Nikonos RS SLR camera; Nikonos 50mm objective and Rene Aumann UW Services X2 teleconverter; two Nikonos S-105 strobes; Ektachrome VS 100 film; F11; 1/125s; TTL. Taken at: 16m depth; diving from MS. FeBrina. Trip organised by Chris Newbert of RS Tours. Shot on: 13:25 1st March 2005; sunny, slight current. Ascidians are chordates, belonging to the same animal group as vertebrates. Most are transparent, gelatinous, tubular in shape or encrusting. Sea Squirts have an oral or incurrent siphon and a cloacal or excurrent siphon that is used for feeding. The boy of an adult is covered with a tough layer of polysaccharides and proteins. Many sea squirts have spectacular coloration. Most tunicates are hermaphrodites, whilst some species reproduce asexually.
