Crown of Thorns Starfish Threaten the Great Barrier Reef
Help us save the Great Barrier Reef. Your donation will support our research on containing the Crown of Thorns Starfish outbreaks that devastate the Reef: http://australianmuseum.net.au/Help-the-Reef Since 1980, Australia's Great Barrier Reef has lost half its coral. The main causes are storm damage and COTS. We can’t stop the storms, but we can promote coral recovery by containing COTS. Further research is required on causal factors and methods of control. The Australian Museum’s Lizard Island Research Station is ideally located for COTS research and has hosted significant discoveries, such as the new single-shot injection technique shown in the video above. It is expensive to maintain first-rate marine research facilities on a remote tropical island. Visiting scientists contribute as much as they can afford, but the Station could not continue without the ongoing support of the Australian Museum and donors.

How a Crown-of-Thorns starfish reacts to the smell of a Giant Triton
Researchers at AIMS are currently investigating the mechanisms that drive Crown-of-thorns starfish (COTS) outbreaks on the Great Barrier Reef and how they might be controlled. One project, part of the Australian Government's National Landcare Initiative Reef Rescue Program, is looking into the potential for natural predators to be used to control COTS numbers. The giant triton, a large marine snail, is a known natural predator of COTS. Using its well-developed sense of smell, a giant triton is able to locate and pursue a COTS, eventually catching, killing and eating it. However, COTS also have a keen sense of smell, and can sense when a giant triton is near. Read more about the project here: http://www.aims.gov.au/docs/media/featured-content/-/asset_publisher/Ydk18I5jDwF7/content/the-triton-that-ate-the-crown-of-thorns Watch the video to see how a COTS reacts to the scent of a giant triton.

Crown of Thorns Starfish invasion - SATAFIA  Session in NAPAI - Caluya, Antique, Philippines - April
We faced a Crown of Thorns Starfish invasion and we tried to do damage control with the help of the local pana fishermen. The video was taken in Napai, one single dive-site/pana fishing spot in Caluya Antique, Philippines. in one session more than 1800 pieces got collected and removed. we were only collecting in the shallow area since we have no scuba gear available. Unfortunately the COTS became a constant challenge. Caluya is a group of 10 Islands and it seems the COTS are just moving from island to island and leave a path of destruction. We hope to raise awareness with the locals, that they might organize themselves to maintain their fishing-grounds 'free' of Crown of Thorns Starfish. We tried to offer a small financial incentive of 1php/pcs. for the locals to collect the COTS. in some areas the COTS were like a carpet over the hard corals, a good free-diver is collecting up to 15pcs in one single dive. Special thanks to DFS - German Environmental Consulting for raising awareness on the issue and providing a cash incentive for the fishermen. http://www.dfs-online.de/

Pacific triton hunts and eats crown-of-thorns starfish
The Pacific triton (Charonia tritonis, also known as the “giant triton”) is a large marine snail that inhabits coral reefs throughout the Indo-Pacific region. They feed on echinoderms, and are particularly fond of crown-of-thorns starfish, a coral-eating starfish that occurs in outbreak proportions on the Great Barrier Reef and elsewhere. Despite the COTS sharp spines and having a highly toxic coating (saponin), tritons are highly effective COTS hunters, as shown in this video, taken at AIMS' Townsville facility.

At first glance, starfish, more properly called sea stars, aren't doing much of anything. But Jonathan's investigations reveal a slow-motion predator that hunts and attacks its prey. Traveling the world, Jonathan investigates sea stars from the tropics to the Antarctic and uses time-lapse photography to reveal an amazing complexity to the world of the sea star. ********************************************************************** If you like Jonathan Bird's Blue World, don't forget to subscribe!

Starfish, more correctly called sea stars, live just about everywhere in the ocean, from the tropics, to Antarctica and everywhere in between. They come in all shapes and sizes from fat and stubby… to long and skinny. This brittle star walks with a coordinated effort using its rays like legs. But most sea stars get around using hundreds or thousands of tiny tube feet on their underside. This is a Northern Sea star, living in the coastal waters of New England, and it’s a predator. It’s hunting a scallop. It’s a drama played out in slow motion as the sea star moves in for a grip on the scallop’s shell. But the scallop is not defenseless. With a mighty blast of water, the scallop jets away to safety. So the sea star wraps itself around a mussel. Mussels are attached to the bottom and can’t get away. The sea star uses it’s strong tube feet with suction cups to pull the mussel open a tiny bit, and digests its victim by injecting its stomach inside the mussel. Picking up the sea star, I can see that it has the mussel firmly in its grip. But not all sea stars feed on mussels and scallops. A Basket star feeds on plankton in the water. It has finely branched arms that act like a net, to catch the tiny bits of food floating by. It positions itself to be able to grab as much plankton as possible in the current. Exploring a reef in the tropical Pacific, I find a Crown-of-thorns sea star dining on the coral. This thorny, armored sea star is one of only a few animals that can digest living coral. It wraps itself around a coral colony and eats the polyps, leaving a dead, bleached coral skeleton behind. Here’s a healthy colony of plate coral. And here’s one that has been eaten by a crown-of-thorns. Outbreaks of these sea stars have been known to kill entire reefs. Carefully picking one up to avoid the sharp and venomous spines, I can see the stomach, which the sea star inverts out of its mouth to digest the coral outside of its body. These sea stars are the second largest in the world, growing bigger than a dinner plate. But if you think these are big, wait until you see the largest sea star in the world! To find it, I've come all the way to British Columbia. I'm looking for the Giant Sun Star, and you won't believe the size of this thing! In the cold, murky waters of the Canadian north Pacific, I swim through beautiful gardens of sponges, anemones and soft coral, searching for a Giant Sun star. And then, down on the bottom, I find what I’m looking for. It has up to 24 arms, more properly called rays and reaches 3 feet across. This is the world’s largest sea star! Compared to most sea stars, the Giant Sun Star is a speed demon, cruising along the bottom in search of its favorite food—other sea stars and the occasional sea cucumber! Here, a sea cucumber makes an emergency retreat to escape this hungry Sun Star on the move! A thousand miles south on a reef in the tropics, I find a blue Linckia sea star on the bottom. Like the vast majority of sea stars, this one has only 5 rays. With tiny tube feet on its underside, this sea star barely seems to move, but when I speed things up with time lapse photography, Linckia sea stars appear very active, moving about and grazing the bottom for food. But even more curiously, they are polite, restraining from walking on top of each other. Like bumper cars, when one Linckia touches another, they each go the other direction. It’s all very civilized. In an hour, a Linckia on the move can travel several car lengths.

Crown-of-Thorns Starfish
Hordes of Crown-of-Thorns starfish can devour coral reefs. The Crown-of-Thorns starfish (Acanthaster planci) feeds on coral. Low numbers of this starfish increase reef diversity, but large numbers can destroy reefs. Avoiding human activities that increase starfish numbers is more effective than trying to control Crown-of-Thorns outbreaks once they happen.

Scientists take on Pacific crown of thorns starfish threat (PMC)
SUVA (Pacific Media Centre): The crown-of-thorns phenomenon may sound like something from a Hollywood storyline. But instead it's the name given to the rapid mass reproduction of the crown of thorns (COT) starfish - the biggest threat to the Pacific's coral reefs. Named for its long poisonous spines on its exterior, the starfish are the primary cause for the extinction of live coral in the South Pacific. Dr Pascal Dumas, a researcher at the Institute for Regional Development (IRD), has been working on the phenomenon in the Pacific for almost a decade. Although this has always been a natural marine cycle for the starfish, climate change such as warming sea temperatures and nutrient run off from floods and drains into the sea are possible factors for the starfish’s population explosion.

Crown of Thorns sea star - Puako, Hawaii
Definitely one of the most unusual looking creatures on the reef! These sea stars have 19-20 legs and eat the algae on coral, leaving the coral blanched white in their wake (which you can see at the end of the video). I saw these creatures in Puako Bay on the big island. These are very otherworldly creatures.

Frederieke Kroon: Identifying fish predators to manipulate crown of thorns starfish predation
Population outbreaks of the Crown-of-Thorn seastar (CoTS), Acanthaster cf. solaris, have resulted in a significant decline in coral cover on the Great Barrier Reef (GBR). Release of predation pressure remains one of the most likely hypothesised influences on CoTS population dynamics. To inform management of CoTS predators, we aim to identify fish species that predate on different life history stages of CoTS on the GBR. We have developed a highly innovative and non-invasive method to identify CoTS DNA in fish faeces, and successfully applied this in both laboratory and field settings. Specifically, we are applying a genetic marker, developed to identify A. cf. solaris larvae in seawater, to identify potential fish predators of CoTS that may be important as natural controllers. Fish species of interests are those that may prey on larval, post settlement and adult CoTS. So far, CoTS eDNA has been confirmed in faecal matter of three planktivorous fish species, suggesting they may play a role in reducing larval abundance and settlement. Future work will focus on fish species that may prey on settled CoTS, including species that are fished recreationally and commercially. This work will inform CoTS management by recommending approaches around the use of predator manipulation in mitigating CoTS outbreaks. eDNA, fish, fisheries, predation, [email protected]

Since the 1960's, land-based nutrient runoff has accelerated outbreaks of COTS which are destroying large areas of reef. Link to project page: https://wiki.qut.edu.au/display/cyphy/COTSBot

Me interacting with crown-of-thorns sea stars. This footage is from Hawaii (the Big Island), where the crown-of-thorns population density is normal and does not present a problem (unlike the "outbreak" situations on the Great Barrier Reef). Where I dive, crown-of-thorns are few and far between, and finding one is always a thrill to me because they are such beautiful and amazing creatures. I love counting the arms (the number varies) or very gently coaxing one up. If you're going to handle a crown-of-thorns, the trick is to be extremely slow, relaxed, and gentle. You have to be careful where (and mostly how) you touch it, and to be aware that at any time you could be pricked, and accept that and be okay with it. They are covered with incredibly sharp venomous thorns that can easily puncture a glove. Some people have very bad (allergic?) reactions to being pricked, but I have been pricked a couple of times (before I got my taming techniques down) with no ill effects other than a little blood and the quick sharp pain, like a spindle. (Being pricked made me SMILE.) Later the spot was tender, swollen/bulgy, and blue just around the puncture location, but it was fine by the next day. However, I don't recommend touching them unless you're aware of the dangers of being pricked, because it's very easy to do it wrong, and it can happen in an instant. If you do pick up a crown-of-thorns and turn it over, the underside is breathtakingly gorgeous. It's one of the most beautiful things I've ever seen. Flower-like, alien, unfurled. A gaping, circular, teeth-lined mouth. Delicate, soft colors, radiatingly symmetrical. Erotic. Fierce. Lovely and voracious like a flower. And all those feet, feet, feet, reaching and exploring, hanging on. The tube feet are huge and yellow, with suckers on the ends, and the crown-of-thorns will hang on to your hand with a powerful grip. Okay, maybe I'm a little crazy, but I AM in love.

Crown of Thorns Starfish
Killer of coral reefs. The Crown-of-Thorns Starfish clasps a stick. Hold out of the water. If you step in its toxic thorns you'll have a real problem. This starfish moves much faster than common starfish.

Crown of Thorns Starfish
The mystery of one of the most efficient eating and breeding machines in nature. This starfish eats only one thing - coral. It has already reached uncontrollable numbers over a large part of the Great Barrier Reef. Also under impact from global warming and coral bleaching, this diverse and delicate reef ecosystem is under extreme pressure.
