Japanese fishermen spotted this rare frilled shark (
Chlamydoseachus Chlamydoselachus anguineus) near the sea surface. Shortly after the fish was captured by marine park officials, however, it died:
The frilled shark is typically found at a depth of around 600 meters (2,000 feet). Its slender body grows to about 160 cm long, and unlike most sharks, which typically have 5 sets of gills, the frilled shark has 6 sets. It is known as a “living fossil” for its resemblance to extinct, Paleozoic sharks.
