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.

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.

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.

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.

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.

More footage of me interacting with crown-of-thorns sea stars on the Big Island of Hawaii! (Where the crown-of-thorns population is NORMAL and their limited predation is not threatening the reefs.) This time it's a baby, only 3.5" wide. 16 arms. I've NEVER seen a baby crown-of-thorns before! I found it on a shore dive at Pine Trees on the Kona Coast, from an entry spot we named "Pine Tree Portal." When I spotted it, it was crawling across a patch of sand at a very speedy rate. Don't handle crown-of-thorns unless you know what you're doing--the thorns are venomous and extremely sharp, and people have had very bad reactions to being pricked!

This work presents a novel vision-based underwater robotic system for the identification and control of Crown-Of-Thorns starfish (COTS) in coral reef environments. COTS have been identified as one of the most significant threats to Australia's Great Barrier Reef. These starfish literally eat coral, impacting large areas of reef and the marine ecosystem that depends on it. Evidence has suggested that land-based nutrient runoff has accelerated recent outbreaks of COTS requiring extensive use of divers to manually inject biological agents into the starfish in an attempt to control population numbers. Facilitating this control program using robotics is the goal of our research.

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]

Armed with only scuba suits and syringes, an army of divers led by Col McKenzie, is taking on one of the biggest threats to the Great Barrier Reef - the Crown of Thorns Starfish (CoTS) - one shot at a time. In healthy numbers Crown of Thorns Starfish are essential to the Great Barrier Reef, consuming fast-growing corals allowing slower growing corals to develop. But, left unchecked, one CoTS has the potential to devour large coral outcrops. Thanks to a new culling technique, which sees the starfish injected with bile salts from cattle, Col McKenzie and his team at AMPTO are reclaiming reef territory faster than ever before, killing more than 400,000 of the starfish since 2012. Col says it’s not all doom and gloom as the media sometimes suggests. The Great Barrier Reef is spectacular. It’s as big as Japan and one of the few Coral Reef Systems where you can see great coral, whales, coral fish, turtles and big sharks on a daily basis.

Scientists fear starfish could combine with bleaching in “perfect storm” of Reef destruction. A new WWF-Australia report urges a crackdown on the “excessive, and often illegal,” use of industrial fertilisers that trigger outbreaks. – MORE FROM WWF-AUSTRALIA SOCIAL: Facebook... ►https://www.facebook.com/wwfaustralia/ Instagram.. ► https://www.instagram.com/wwf_australia/ Twitter........ ► https://twitter.com/WWF_Australia/ WEBSITE: https://www.wwf.org.au/ SUBSCRIBE TO OUR CHANNEL: https://www.youtube.com/subscription_center?add_user=wwfaustralia – ABOUT WWF-AUSTRALIA: WWF has a long and proud history.

One of the most dominant predators of Pacific corals is the crown-of-thorns seastar, Acanthaster planci. A. planci is considered a generalist coral predator with a preference for branching species such as the acroporids (Carpenter, 2004). The seastar feeds on the coral by everting its stomach over the live coral and secreting a protease enzyme that breaks down the coral tissue (Birkeland and Lucas, 1990). Coral consumption is slow, requiring a leisurely 4-6 hours to digest a coral branch or a small colony. It is estimated that a single seastar can consume 5-6 m2 of live coral per year (Birkeland 1989). The immediate ecological impact of A. planci outbreaks on most reefs is the modification of community structure and the colonization of algae in newly available space following coral mortality (Birkeland and Lucas, 1990). The following footage shows slow-moving crown-of-thorns.
