A deep-sea cucumber known as a “headless chicken monster” has been filmed in the Southern Ocean for the first time using camera technology developed by Australian researchers.

The creature was filmed off East Antarctica and it is the first time the species has been seen in the area.

“Some of the footage* we are getting back from the cameras is breathtaking*, including species we have never seen in this part of the world,” Australian Antarctic Division Program leader Dirk Welsford said.

The creature, En ypniastes eximia, has only been seen before in the Gulf of Mexico and was captured in the Southern Ocean by cameras developed by the Australian Antarctic Division.

It is known as a “headless chicken monster” because that’s what it looks like.

Our oceans are home to an incredible number of amazing sea creatures

“The housing that protects the camera and electronics is designed to attach to toothfish longlines* in the Southern Ocean, so it needs to be extremely durable*,” Dr Welsford said.

“We needed something that could be thrown from the side of a boat and would continue operating reliably* under extreme pressure in the pitch black for long periods of time.”

The information collected from the cameras is being presented at the annual Commission for the Conservation of Antarctic Marine Living Resources meeting starting in Hobart yesterday.

Australia’s commissioner for the meeting will push for a new East Antarctic Marine Protected Area.

“The Southern Ocean is home to an incredible abundance* and variety of marine life, including commercially sought-after* species, the harvesting of which must be carefully managed for future generations,” commissioner Gillian Slocum said.

The 10-day Antarctic conservation meeting will also include proposals on how to respond to climate change.

Not a vegetable or a fruit!

A marine animal with a tough, leathery skin in a group of creatures called echinoderms, with starfish and sea urchins.

Tube feet that look like tentacles around their mouths gather algae, tiny aquatic animals and waste into its mouth.

Fish and humans eat sea cucumbers. They are a delicacy — a special-occasion food — in Asian cuisines*.

Home is the ocean floor. Some species live in shallow water, others in deep water. There are about 1250 known species found all around the world.

Defence against attack is pretty spectacular! Some discharge sticky threads to capture enemies. Others can mutilate* their own bodies. And others shoot their organs out of their anus*. The good news is they quickly grow their organs again.
