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.

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.

Injecting Poison into Crown of Thorns Starfish
More information at: http://www.oceanguard.com - Right now a war is being waged beneath the waters of the Great Barrier Reef on tourists reefs off Cairns by the Association of Marine Park Tourism Operators (AMPTO). They are trying to control out of control numbers of Crown of Thorns Starfish on their reefs. Supported by State and Federal Governments who have only in recent years fully realised the problem that is the Crown of Thorns Starfish (COTS) which is midway through a fourth major outbreak. What about the rest of the reef? In regard to the rest of the reef system, what is missing is a sense of urgency in the battle against (COTS) from the authorities, for In several months time, the breeding season of COTS will begin, where tens of thousands of these coral eating monsters will congregate to breed, with each female adult starfish capable of producing 60 million eggs. With less predators to control COTS in their early stages, you are looking at millions of adults in the future let loose to destroy what remains of the reef. 4000 adults can eat an acre of live coral in a week. Do the maths. At that rate, there will be soon nothing left.
The Underwater Army Tackling Crown of Thorns Starfish
They're divers on a very important mission; to preserve the world's largest coral reef ecosystem from a predator whose appetite knows no bounds. One of the team securing the containment lines around the reef is Mat Trueman, a dive supervisor who now dedicates his life to the fight against Crown of Thorns Starfish (CoTS). "I like to do my part to make sure we're getting rid of the Crown of Thorns on the reef so that it helps preserve it for future generations,' said Mat. Mat works for the Association of Marine Park Tourism Operators (AMPTO), the organisation that manages the Crown of Thorns Control Program in Queensland. He leads teams of up to 12 men and women on 10-day voyages off the coast of Cairns and Port Douglas in Tropical North Queensland. While it sounds like an idyllic job, diving the Great Barrier Reef four times a day - to contain outbreaks - is gruelling work. Thanks to a new culling technique, which sees the starfish injected with bile salts from cattle, Mat and his team are reclaiming reef territory faster than ever before. One quick and simple injection euthanizes a starfish, without harming the reef, a far cry from the previous method in which divers had to inject the reef pests up to 30 times.

Crown of Thorns
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.

Back in 1984, The PMBC surveyed crown-of-thorns starfish outbreaks in the reefs on several islands in the Andaman Sea. Serious outbreaks were found on some, while others did not show outbreaks, however there was a presence of dead coral which was suspected to have been caused by crown-of-thorns starfish. In early 2007, an outbreak was found in a small cove, south of Ba-ngu Island (the northernmost island of the Similian group). The reef had been hugely degraded within a few months as a result. The staff of PMBC and Similian National Park removed 65 in an area of about 150 x 50 metres in March 2007. At the present time, outbreaks are still found in some areas. At Racha Yai Island, south of Phuket, recent outbreaks were found at some spots on the east coast of the island, and this year near Ko Aeo, south east of Phuket. The crown-of-thorns starfish is a natural part of the reef ecosystem, and if the population levels are balanced, it is beneficial to the environment. These starfish choose to eat fast growing coral species, particularly staghorn coral. Fast growing coral species can cover areas very quickly, and compete for space with slow growing species. The crown-of-thorns starfish helps to maintain a balance, and allows space for the slowing growing species, therefore creating higher levels of diversity. Currently, high levels of fertilizer are used in agriculture, and are subsequently being flushed to the sea. This fertilizer provides food for phytoplankton, and when phytoplankton blooms it causes zooplankton to bloom as well. The larvae of the crown-of-thorns starfish begins as zooplankton, so the presence of fertilizer causes the crown-of-thorns starfish to proliferate. Another cause of the abundance of these starfish is a lack of predators such as the rare Triton shells, or triggerfish, due to illegal fishing and sales of shells. Khun Nipon also wants to tell people not to feed fish with bread as the fish then do not eat naturally, including the larvae of crown of thorn starfish. Many divers have asked him how many crown-of-thorns starfish in a certain area define it as an outbreak. Scientists approximate if there are greater than 10 individuals in one hectare, that area is considered to have an outbreak. If there are greater than 30 individuals in one hectare, the outbreak is at a very serious level. If any divers find an outbreak case, it is acceptable to kill or remove the starfish to help preserve the affected reefs. However, if the outbreak area is within a National Park, a permit must be obtained before anything can be removed. There are several methods which can be used to limit the number of crown-of-thorns starfish. You can use a knife to cut the central part of the starfish body, but should take care not to merely cut it in half, as the two halves can regenerate. Another option is to collect the starfish and bring them on shore to dry out. -------------- You may also call khun Nipon at the PMBC for more information at Tel : 076 391128 Fax : 0 76 391127 Email : [email protected]
