Crown of Thorns Starfish Threaten the Great Barrier Reef
 
06:32
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
 
00:52
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.

Sea Stars | JONATHAN BIRD'S BLUE WORLD
 
08:30
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! You can buy some Blue World T-shirts & Swag! http://www.blueworldtv.com/shop You can join us on Facebook! https://www.facebook.com/BlueWorldTV Twitter https://twitter.com/BlueWorld_TV Instagram @blueworldtv Web: http://www.blueworldTV.com ********************************************************************** You might not think of sea stars as being very intelligent, and you’d be right, but you might be impressed by some of the amazing things they can do, especially considering they don’t have a brain! 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.

Pacific triton hunts and eats crown-of-thorns starfish
 
00:50
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. Avoiding human activities that increase starfish numbers is more effective than trying to control Crown-of-Thorns outbreaks once they happen.

It's famous for its natural underwater vertical swim through or chimney which divers can enter at 6 metres and exit at 18. It is also the visiting site of many larger pelagic fish including chevron barracuda, big schools of mackerel, jacks, trevally and tuna. You may encounter a seasonal whale shark with over 40 spotted at Sail Rock in 2012 alone. Giant moray eels and lion fish have also taken up residency.

The predatory crown-of-thorns starfish (COTS) is a key threat to the Great Barrier Reef, in addition to the impacts of climate change, such as coral bleaching and pollution. Outbreaks are becoming more common, believed to be driven by human activity. Recent research shows manual COTS control is effective.

In fact, these little blighters are one of three threats that the great barrier reef encounters every day, the other two being coral bleaching and cyclone damage. Now the other two threats are pretty hard to deal with… but killing the starfish is, to be honest pretty easy. The only issue is that this of course takes time and plenty of man hours to do, But not anymore! Queensland researchers have developed world first robots that have been designed to inject crown of thorns starfish with a lethal injection. ::Contributors:: - ABC News - Laura Garty - NOAA - Mark Newman - Shaun Johnson ....................................

Crown of Thorns
 
00:52
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.

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. MOre info here http://bit.ly/xusqw5

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.
Jairo Rivera - Recent advances and knowledge gaps in crown-of-thorns sea star

Seminar title: Recent advances and knowledge gaps in crown-of-thorns sea star Seminar type: CoralCoE seminar series Presented by: Jairo Rivera Date: Thursday, 28 February 2013 Abstract: Outbreaks of the crown-of-thorns sea star (COTS), Acanthaster planci, represent one of the most significant biological disturbances on coral reefs and remain one of the principal causes of widespread decline in live coral cover in the GBR. Control of COTS outbreaks may be the most immediate and effective mechanism by which to reverse sustained declines in the abundance of live coral cover, thereby maximizing opportunities for coral reef organisms to resist and adapt to sustained and ongoing threats from climate change and other more direct anthropogenic disturbances. However, previous control measures have been costly, largely ineffective, and often involved dangerous side effects. Attempts to control outbreaks, either by collecting adult individuals or injecting individuals with toxic chemicals, are ineffective at all but very localized scales, and control of COTS through manipulation of predators, parasites or pathogens has not been fully investigated. During my seminar I will talk about three different approaches that are being explored. The first approach is focused on the identification of natural predators and parasites of COTS. Observations of actual predation on A. planci are rare and there is little direct and quantitative data to assess the role of predators in limiting the population size of A. planci. The second approach is the erradication of A. planci through injections of proteins and osmoregulators that induced rapid disease and death and are less harmful to the marine environment when compared to other chemicals used. The third approach is a transmissible disease that can be induced under certain environmental conditions and the development of taxonomy studies for the identification of natural enemies as the first step in developing an effective control method. Biography: Jairo completed his Bachelor of Veterinary Science (Hons) at the University of Caldas. After that he did 3 GradDip in Medical imaging (Radiology, Ultrasound, CT and MRI). He then obtained his first Doctorate in Veterinary Science with emphasis in Animal Surgery and Medicine at the University of Leon (Spain) awarding a Summa Cum Laude and patented his Bone graft. Jairo worked as a professor of animal surgery, radiology and internal medicine for seven years and then made a career shift and moved to Australia and completed a PhD in Marine Biology and Microbiology at James Cook University. The primary focus of his research is the Pathogenesis of crown-of-thorns (Acanthaster planci).

Crown-of-Thorns

The infamous Crown-of-Thorns sea star(Acanthaster planci). Located in Hawaii. Fortunately, the hawaiian islands have natural predators for these sea stars; usually small shrimps, fireworms, small crabs, and the Triton's Trumpet Snail(Charonia tritonis)/pu; 'ole have been known to predate on these venomous invertebrates. A word of caution for a first-time encounter; do not touch the CoT's spines as they are venomous. Most important fact: Cutting up or removing the CoT from the reef won't solve the problem. Cutting up echinoderms like astaroidias like starfish won't kill the animal, in fact; you'll only end up making more of them since they can regenerate into a new animal should a limb be torn or cut off. Best method of removal is to carefully pry the animal off the rock with a stick(i.e. rod, spear, pole) and "relocate" it to a sandy patch far from any rocks and coral. That way the local predators can get at the animal. This individual is the biggest I've seen, by far. NEVER, EVER, cut the CoT to pieces.

https://wiki.qut.edu.au/display/cyphy/COTSBot Crown-Of-Thorns Starfish (Acanthaster planci) are described as one of the most significant threats to the Great Barrier Reef. Since the 1960's, land-based nutrient runoff has accelerated outbreaks of COTS which are destroying large areas of reef. With few natural predators, traditional control of COTS required manually injecting the starfish in excess of 10 times with a biological agent. In 2014, a new agent was released, which was developed by the James Cook University (JCU) requiring only one injection per starfish. This advancement provided the stimulus for us to revisit automated (robotic) COTS population control and monitoring. The intention of COTSbot is to provide a proof-of-concept robotic system that consolidates prior and ongoing research into image-based COTS detection, robotic vision, manipulator control, and shallow water Autonomous Underwater Vehicle (AUV) design, navigation and control, to directly facilitate COTS reduction. This multi-stage project will validate and demonstrate AUV performance to stakeholders and ensure the system components are a useful and flexible enabling foundation technology for environmental monitoring beyond the problem of COTS control.
