Do they need camouflage? I'm Jonathan Bird and this is Shark Academy! Most people, when they imagine a shark, think of something like this: a reef shark, with the classic sharky look. Almost all sharks of this type are grayish with a darker top and lighter underside. This is called countershading. What is it for? Imagine sunlight falling on a shark with no countershading. The top would be illuminated more brightly than the underside. This would make the shark very easy to see, and its shape is obvious. However if you darken the top of the shark so that it matches the brightness of the underside when sunlight falls on it, now it's much harder to see, and its shape has been disguised. That is countershading, and it's what sharks do to help blend in while swimming in plain sight. Other sharks like the Wobbegong live entirely on the bottom and hunt by ambushing their prey. They have evolved complex coloration and camouflage to blend in to the sea floor. The Whale shark? Well, in addition to counter shading it has spots on top. Biologists think these help the shark use the dappling of sunlight near the ocean surface to disguise their shape. Why does the world’s biggest fish need camouflage? Well, that’s anyone’s guess! Don’t go away! If you’re interested in sharks, there are more than 30 Shark Academy episodes to watch! You can also join my underwater adventures on Jonathan Bird’s Blue World!

Sea Turtle Cave | JONATHAN BIRD'S BLUE WORLD Extra

In Malaysia there is an island called Sipadan, famous for beautiful reefs, lots of fish and tons of sea turtles. But there is also a cave where sea turtles die. Jonathan and the team visit the cave in this spooky extra!

One of the locations where we filmed is a tiny island in Malaysia called Sipadan, that has a huge sea turtle population. The island is a divers’ paradise—surrounded by beautiful coral reefs, and teeming with fish. Sipadan is actually the top of a seamount, so underwater it has steep walls dropping quickly into the abyss. In the side of one of the walls is a small cave. It doesn’t go back very far, but there is a sign posted to warn divers. People should not venture in without training or a qualified local guide. Our divemaster and guide had been in this cave hundreds of times and knew it like the back of his hand. He wanted to show us something, so we went in with him. In one corridor, you can see the line on the wall where the sea level was long ago, during an ice age, when the oceans were lower. This section was half full of air. But around the next corner, we found something spooky. The remains of a sea turtle. Looking around, we discovered that the room is filled with the remains of sea turtles. Shells, bones, skulls. In one corner, the remains of a sea turtle laid out just as it died. Dozens of sea turtles lie silently in this room. Why? Did they come in here to die peacefully? Did they come in for a place to rest, get lost and drown? We will never know. The sea turtle cave is one of the great mysteries of Sipadan Island.

Shark Attacks | SHARK ACADEMY

In this fun and enlightening video, Jonathan Bird talks about shark attacks! How likely are you to be attacked by a shark? Are sharks statistically dangerous? Find out more than you ever needed to know about shark attacks! ********************************************************************** If you like Shark Academy, don't forget to subscribe!

I’m Jonathan Bird, and this is Shark Academy! You are 75 times more likely to drown at the beach than to be killed by a shark. And…for every human killed by sharks, about 25 million sharks are killed by humans. It hardly seems fair for us to be afraid of them. In an average year in the USA, there are only about 16 shark attacks, and most are not fatal. On the other hand, 41 people a year are killed by lightning in the USA! Nevermind what this tells us about people standing outside in the rain, it means sharks just aren’t that dangerous. In fact, 15,000 people are killed each year in bicycle accidents in the USA. So just to put it in perspective, let’s look at 20 things around the world that kill more people every year than sharks: Traffic, falling coconuts, high school sports, champagne corks, tripping, choking on food, bacteria from raw meat, cows. Seriously. Wind, bee stings, horses, cold weather, falling from ladders, hot tap water. Seriously., ants, dogs, falling icicles, Hippos. I couldn’t make this stuff up. Lightning, vending machines, jellyfish, and even falling out of bed (not kidding!) And the most dangerous animal to humans? This: the malaria-carrying mosquito, which is responsible for 800,000 human deaths every year. So next time you are worried about sharks, don’t be. Watch out for sneaky vending machines!

Shark Teeth | SHARK ACADEMY

I'm Jonathan Bird and this is Shark Academy! Different sharks feed on different things, and so shark teeth have evolved along with sharks. Small bottom-dwelling sharks that feed mostly on invertebrates have flattened teeth for crushing. Sharks that feed on fish typically have pointy teeth designed to grab and hold slippery prey so it can't get away, and the prey is swallowed whole. The Mako and Sand Tiger shark have these kind of teeth. Sharks that feed on larger animals have more saw-shaped teeth designed for taking bites out of larger prey. The white shark, Bull shark and Reef sharks have teeth like this. The most extreme example of a cutting tooth is the fossilized tooth of the extinct Megalodon shark, kind of like a prehistoric Great White that was larger than any shark alive today, including the whale shark. The Megalodon had the biggest teeth of any shark known. This is a set of jaws from a Bull shark and in the front you can see the active row of teeth that the shark was using, but if you look in the back, you can see, like a conveyor belt, there’s a steady supply of replacement teeth ready to go as soon as one of those front teeth would break off or fall out. So the shark had essentially an unending supply of teeth. In this way, sharks never run out of teeth and they don't need to go to a dentist! It's estimated that some sharks go through 35,000 teeth in a lifetime!

Shark Reproduction | SHARK ACADEMY
 
03:51
In this great educational segment, Jonathan explores the reproductive strategies of sharks, explaining how some sharks lay eggs (oviparity), produce live young (viviparity) or produce eggs that develop internally (ovoviviparity). ********************************************************************** If you like Jonathan Bird's Blue World, don't forget to subscribe!

Or both? How do sharks reproduce? I’m Jonathan Bird and this is shark academy! Unlike fish, which produce large amounts of eggs, most of which never reach maturity, sharks produce far fewer, but larger, offspring, and they have a much better chance of reaching adulthood. Sharks can reproduce in several ways. Many small sharks, like the horn shark, the swell shark and cat sharks actually lay eggs on the bottom. The baby shark develops in there, living off a yolk sac filled with nutrients. The baby, a miniature version of its parents, is born after a few months to a year of gestation, depending on water temperature and the species. Sharks using this reproductive strategy are called oviparous. Meaning egg-laying. Other sharks are viviparous. They give birth to live young which develop inside the mother shark, receiving nutrients and oxygen from mom through an umbilical cord, just like humans. Larger sharks like Blue sharks, Bull sharks and Hammerheads use this technique. The last group of sharks are ovoviparous, (also known as Aplacental Yolk Sac Viviparous). In this system, the mother produces eggs like the oviparous system, but instead of laying her eggs on the bottom, she carries them inside her body until they hatch. When the babies pop out, you might think the shark was viviparous, but the babies had no umbilical cord inside, they lived off a yolk sac. In the weird category, the Sand Tiger shark has a strange variation on its ovoviviparous reproduction known as intrauterine cannibalism. The mother produces up to 50 pups in each of two uteruses, but the first baby in each uterus that reaches about 4" long eats all its siblings! After 12 months of gestation, the mother then gives birth to a pair of 3 foot long pups! Pups that are well fed! Because sharks put so much more time, effort and energy into producing a viable offspring than bony fish do, they give birth to far fewer pups. A whale shark produces the most pups of any shark—around 300 at a time—but then again, mom is the size of a bus. The Thresher and Sand Tiger only produce two pups at a time. The Blue shark can produce 135 at a time, which is a lot for a shark not the size of a bus. Gestation is long too, averaging 9-12 months. Baby Spiny Dogfish take 22 months—almost two years—for their young to develop. Most sharks take quite a while to become mature enough to reproduce as well. Great Hammerheads take 9 years. Lemon and Bull sharks take 15 years. Spiny Dogfish? 20 years. So, between the small litters, a long gestation period and long time to reach maturity, sharks just don’t reproduce very quickly. This is the reason they are so vulnerable to overfishing. If you’re interested in sharks, there are more than 30 Shark Academy episodes to watch!

It's probably the most famous reef in the world, and the largest. It's not just visible from the air, but from space. Cairns is a city in Queensland, the northeast state of Australia.

Ninety minutes later, I arrive at the Sunlover pontoon. I have never seen a dive operation like this before. The boat is huge, but we don't dive from the boat. Instead we dock at this massive pontoon—sort of like a floating dive shop—and spend the day right next to the reef in a protected spot. Pure luxury! A lot of people who don't dive love to come out and get a first hand look at the reef here. The water is clear and it's not too deep. But even people who don't like to get wet can see the reef. On a submarine! And for a diving experience unlike any other, anyone can try the Sea Walker experience. All you need is a 40 found helmet! I walk down the stairs into the water and the staff outfits me with the strangest piece of dive gear I have ever used. With no fins on, I just walk out to a massive school of fish. My hair doesn't even get wet! This is incredible! They’ve got about a thousand fish around here. I feel like Doctor Sylvia Earle – deep sea diver. This is a very different way to go scuba diving, and this just goes to show you if you don’t want to wear a mask, don’t want to wear a regulator, and maybe you can’t even swim that well, you can do this! It’s just like walking. You know I’ve had a lot of experiences underwater, and this is definitely one of the most unique! To demonstrate how this helmet works, I have an ordinary water glass, which obviously is full of water, but if I turn it upside down, I can fill it with air. (Fills it with air) And now you can see that it keeps the air in, but if you turn it right side up – so we don’t want to turn this right side up. I pose for a picture, because you never know when you're going to get to do this again! Next I meet Vance Fahey who will be my divemaster for a scuba dive on the reef today. Not only do I have a nice easy staircase to walk right down into the water, but a platform for putting on my fins. I can get used to this! On the platform is a group of new divers getting their first taste of the underwater world. At last I head out onto the reef to explore. I see many types of hard corals, beautiful pastel colored soft corals, and lots of fan coral. Near the reef, I find one of the largest Giant Clams I have ever seen. I can't imagine how much this clam must weigh. The mantle gets its bright colors from imbedded symbiotic algae that harvest the sun's rays for energy. I find a huge crack in the reef and have a little fun swimming through it. On the other end, I'm greeted by a sea turtle. She comes right over. There are lots of divers around this reef and this turtle knows that the divers won't hurt her. Once she has decided that I'm not doing anything terribly interesting, she goes back to looking for her favorite sponges to eat. I turn and head back towards the platform across the shallow reef. At the platform I'm greeted by a friendly Mauri Wrasse. This monster of a fish reaches both the length and the weight of a motorcycle. I'm just glad they prefer to eat crustaceans and mollusks--not divers! I think I've made a new friend!

I’m Jonathan Bird and welcome to Shark Academy! Most bony fish have an organ called a swim bladder that they use to adjust their buoyancy. By adjusting how much gas is in its swim bladder, a fish can keep itself perfectly neutral so it doesn’t sink or float. Sharks have no swim bladder, so they tend to be heavier than water and sink like a rock. Some sharks, like the Wobbegong, have dealt with it by becoming bottom-dwellers. Other sharks, like Blue sharks, have evolved very large pectoral fins to act as airplane wings. As the shark cruises gently through the water, the fins provide lift to keep the shark aloft. Many sharks like the Basking shark have evolved massive, oily livers. The oil is more buoyant than water, and helps offset some of the shark’s density, to help keep the shark from sinking. A few sharks, like the Sand Tiger and the Whale shark are known to gulp air at the surface. By putting some air in their stomachs, they don’t sink quite so much. Not having a swim bladder gives sharks one big advantage over bony fish—the ability to rapidly change depth without worrying without bursting the swim bladder. If a bony fish ascends faster than it can remove gas from the swim bladder, it will literally explode! Check out our other exciting Shark Academy episodes to learn everything about sharks!

Anemonefish and Clownfish: The Real Nemo (HD) | JONATHAN BIRD'S BLUE WORLD
 
06:43
Thanks to the Disney/Pixar movie Finding Nemo, virtually everyone has heard of the clownfish. Jonathan travels the Pacific to investigate the behavior of real clownfish. Even though they don’t actually talk in real life, they are beautiful and fascinating fish to observe. JONATHAN BIRD'S BLUE WORLD is an Emmy Award-winning underwater science/adventure program that airs on public television in the United States. ********************************************************************** If you like Jonathan Bird's Blue World, don't forget to subscribe!

In real life, these little fish are a lot different from their Hollywood portrayal—I mean other than the fact that they don’t actually talk. But you may find these colorful little fish quite surprising. Join me on a dive to meet some real anemonefish! Anemonefish are found all over the tropical parts of the Indian and Pacific Oceans. They are quite common on coral reefs, so it wont take me too long to find one. Searching a reef on the Pacific Island of Yap, I soon come across a pair of Orange-fin Anemonefish, frolicking in an anemone that looks like a shag carpet. They are not afraid of me at all. I can swim right up and look them in the eye. There are 28 different species of anemonefish—all of which are very colorful, but the Clown anemonefish (sometimes called the clownfish) is probably the most beautiful. This is the species that was the basis for the character in Finding Nemo. Anemonefish get their name because they live in a toxic anemone. This lush carpet has venomous tentacles that sting most fish. But the anemonefish is covered in a special slimy mucous that keeps the anemone from stinging it. Because of this adaptation, the anemonefish can live, protected by the anemone, happily playing in the very tentacles that would kill other fish. Anemonefish are not the only animals that can live in the anemone. Cleaner shrimps hide here as well. They eat by cleaning the parasites from the fish, and in exchange for their services, the fish graciously don’t eat the shrimp. But it’s hard to relax when you are batted around by hyperactive anemonefish all day long! The protection afforded by the anemone is the reason why the anemonefish aren’t afraid of me. They know that the anemone’s stinging tentacles keep them safe. If another fish like this damselfish comes near the anemone, the anemonefish become territorial, and chase it away. They protect their anemone just as much as the anemone protects them, so it’s a good relationship. And if a fish gets too close, the anemone gets a meal—using its venomous tentacles to sting and disable the fish. This fish is lunch. The anemone might look like some kind of weird plant, but it’s actually a simple animal with a mouth in the middle. It’s basically a jellyfish that can’t swim. The anemone is a formidable allay to the anemonefish in more ways than one. They use the protection of the anemone to keep their eggs safe too. The female anemonefish deposits her eggs on the reef, under the edge of the anemone. Then her subservient males take over. The males provide all the egg care. The female just sits back and watches. In any group of anemonefish, there is always one anemonefish which is the largest. This is the dominant female. In anemonefish society, the females are the boss. One of the most interesting things about anemonefish is that they are all born male, but as they mature, some will completely transform into females! Only when the dominant female dies will the next male in line get the chance to transform into a female and become the head honcho. Until then, all the smaller anemonefish in the anemone are subservient males. Truth is stranger than fiction as it turns out, and as my dive comes to an end, I realize that anemonefish are even more fascinating than Hollywood would have us believe. The animals of the ocean truly are remarkable.

Nudibranchs | JONATHAN BIRD'S BLUE WORLD Extra
 
04:32
In this fun Blue World extra, we explore a small colorful mollusk known as a nudibranch. Jonathan Bird's Blue World is an Emmy Award-winning underwater science/adventure program that airs on public television in the United States. ********************************************************************** If you like Jonathan Bird's Blue World, don't forget to subscribe!

Some of them are completely unknown by the average person. The nudibranch is one such curious animal. A nudibranch is basically a snail with no shell, sometimes called a sea slug. The bushy tuft on the back of this nudibranch is actually the animal’s gills, which is where nudibranchs get their name. Nudibranch means means “naked-gill.” There are thousands of species of nudibranchs in the world’s oceans in thousands of different color patterns, which makes them very popular with underwater photographers. But the bright coloration isn’t just designed to look cool. Scientists call it aposematic—it’s designed to warn predators that it won’t make a good meal. Most nudibranchs produce foul tasting toxins or acids in the form of a slime on their skin. Fish won’t eat them no matter how tempting they might look. Unfortunately, nudibranchs are not the fastest animals on the reef, and they are somewhat rare too. Finding a mate under such circumstances can be challenging. So nudibranchs are hermaphrodites, meaning each individual has both male and female organs. When any two nudibranchs of the same species meet up, they are always compatible because they are both male and female. They approach each other, extend sexual organs from the side of their bodies, and exchange both eggs and sperm with each other. Each will then go off and lay their fertilized eggs. This brightly colored nudibranch egg mass is produced by the equally brightly colored Spanish Dancer nudibranch. It is one of the largest nudibranchs on Pacific coral reefs, reaching the size of a cucumber. The Spanish Dancer gets its name from the way it avoids predators. When threatened, it can escape by swimming away like a flamenco dancer. The animal has little control over the direction it swims, but it gets up into the water column and away from the predator. Eventually, the nudibranch stops undulating and assumes a gliding position to parachute back down to the reef, hopefully out of harm’s reach. The Spanish Dancer also serves as a kind of magic carpet. It’s passenger: an Imperial shrimp. This is transportation that offers protection from predators, as well as a steady supply of food. The shrimp feeds on the poop of the nudibranch! In exchange for the free room and board, the shrimp keeps the tufted gills of the nudibranch clean. While the Spanish Dancer is big, some nudibranchs are bigger. The Lemon Peel Nudibranch found in the northern Pacific reachs a foot long, making this a small one! And while fish won’t eat it, people do. In the Russian Kuril Islands, it is considered a delicasy. Nudibranchs are found in all the world’s oceans, even in the freezing water around Antarctica! Nudibranchs are one of the great things about life in the ocean, where even a lowly Sea Slug can be a thing of beauty.

Parrotfish Poop! | JONATHAN BIRD'S BLUE WORLD Extra

In this short Jonathan Bird's Blue World Extra, Jonathan discusses where sand comes from and you may be surprised to learn that a lot of sand is actually fish poop!

Sand is basically just fine particles of rock, which have been eroded away from larger rocks. The color of the sand on a beach is determined by what kind of rocks the sand came from. Around extensive coral reefs, coral rock is the source of the sand, so the beach is bright white like the rock it came from. Near volcanic islands like Hawaii, the sand may be very dark, having originated in dark basaltic rock from a volcano. And while much sand is formed by wind and waves eroding away the rocks, there is another most unusual source of sand in the tropics: the parrotfish. Parrotfish love to munch on live coral. Coral only has a very thin skin of living tissue over the limestone skeleton it produces. Parrotfish dine on the coral by scraping it away with extremely hard teeth. The parrotfish inevitably bites off quite a bit of the limestone as it feeds on the living coral. That limestone passes through the fish’s digestive tract and emerges out the other end as finely ground sand particles. Yes, you heard me right, parrotfish poop out sand! A lot of sand. One scientific estimate suggests that as much as 85% of the sand on a tropical beach is made by parrotfish. So the next time you are enjoying a great day at the beach, you can thank a parrotfish for all the free poop.

Sea Cucumbers | BLUE WORLD ACADEMY

In this entertaining short video, Jonathan explains the basic biology of sea cucumbers. A sea cucumber is a relative of starfish and sea urchins contained within the phylum Echinodermata. ********************************************************************** If you like Blue World Academy, don't forget to subscribe!

Virtually everyone is familiar with the sea star, an animal which is a member of the phylum of invertebrates known as Echinoderms, meaning “spiny skin.” Other Echinoderms include the sea urchins and the feather stars. The sea cucumber is another echinoderm—hard to believe since most of them don’t have very spiny skin at all. But the sea cucumbers are most closely related to sea urchins! There are over 1700 species of sea cucumbers in the world’s oceans, and it’s not hard to guess how they got their name. Most are about the size and shape of a large cucumber. But the similarity to a vegetable ends there! Sea cucumbers have tiny tube feet like sea stars and sea urchins. They can move around, albeit somewhat slowly. There are two basic ways in which sea cucumbers feed. The plankton-feeders extend feathery tentacles into the water as a net for passing plankton. The sticky tentacles gather up particles, then one by one, the sea cucumber licks the plankton off each tentacle with a centrally-located mouth. In the rich waters of New England, an Orange-footed sea cucumber feeds on plankton soup. If I tickle its tentacles, the sea cucumber withdraws them for protection. Other species of sea cucumbers feed by digging though the sediments on the sea floor looking for decaying particles. They typically eat a bunch of sand in the process, which passes completely through their digestive tract. It’s a slow process, but seen in a time lapse, a Tiger tail sea cucumber covers a lot of ground looking for food. You might think that an animal like this would be defenseless, but in fact many sea cucumbers possess a fascinating defense mechanism. When threatened, they can eject a sticky goop called cuvierian tubules to ensnare predators. Others can expel poisonous chemicals to drive predators away. As a result, very few animals will dare to attack sea cucumbers. Due to that general lack of predators, sea cucumbers make a safe home for symbiotic partners. An Emperor shrimp lives in safety on a sea cucumber and in exchange for the protection, keeps its host free of parasites. But of course, there are a few predators that can handle the sea cucumber’s defenses. In the north Pacific, Giant Sun stars will attack and eat sea cucumbers. And in the south pacific, a large snail known as a Partridge Tun specializes in eating sea cucumbers using a powerful venom to subdue its victim. The Echinoderms are a diverse and interesting group of animals, with the sea cucumber as its strangest and possibly most fascinating member.
