Scientific submersible makes deep-sea discoveries

CSIRO Media Release – 18 January 2009
Ref 09/07
The remotely operated submersible Jason being recovered on board the RV Thompson. The red cable is the photo-electronic tether to the ship, which controls operations and sends images and data back to the ship. A dead-reef at 1575 metres, dated to approximately 10,000-20,000 years during the last glacial period, located in the Huon Marine Reserve. The low, black mounds are dead masses of the reef-forming coral Solenosmilia. The yellow basket-like animals on the reef are filter-feeding seastars called brisingoids.

A bright red, undescribed species of shell-less coral, called an anthomastid or gorgons-head coral, at 1700 metres deep at the Cascade Plateau, off south-east Tasmania. One of Australia's deepest residents – a bizarre carnivorous sea squirt, or ascidian, standing half a meter tall on the seafloor on the Tasman Fracture Zone at a depth of 4006 metres. The animal feeds opportunistically, triggered when a fish or any other swimming organism touches it. The animal is then trapped by the funnel-like front section, which collapses around the prey item.
