Red Snailfish (Elassodisus sp.)
Snailfish are scaleless with thin, loose gelatinous skin. Their pectoral fins are large and provide for means of locomotion. Snailfish can range between 5 cm to 77 cm in length. They are benthic fish and their diet consists of small invertebrates such as benthic crustaceans, mollusks, and polychaete worms. Some species are also believed to prey on smaller fish. This snailfish was seen at Southern Hydrate Ridge at a depth of about 600 m.
