  • The carnivorous sea squirt is one of many new deep-sea creatures found by U.S. and Australian scientists exploring southern Australia's Tasman Fracture Zone in January 2009. Found on the seafloor, 13,143 feet underwater, the 20-inch sea squirt is said to trap fish and other prey in their funnel-like front section, much like a Venus fly trap. Most of the 2,000 known species of sea squirts are not predatory and filter their food, usually plankton, from the seawater.National Geographic: Bizarre Species Found... (January 18, 2009)

    Modern-day deep-water coral reefs were also found, however, there is strong evidence that this reef system is dying, with most reef-forming coral deeper than 1,300 metres newly dead.—Ron ThresherCosmos Magazine: Carnivorous sea squirt... (January 19, 2009)
