On January 21st, 2007, a thought-to-be-extinct "Frilled Shark" (Chlamydoselachus anguineus) was found alive off the coast of Japan near the Awashima Marine Park in Shizuoka, southwest of Tokyo. The shark was captured but died shortly afterwards.

The shark is about 2 meters long, and, from a distance, resembles a large eel. However, it can can be distinguished as a shark by the 6 gill slits. Its dorsal fin is very small, while it's a**l fin is large. It's caudal fin is also strange; the dorsal part is almost unnoticable. It's teeth are tricuspid, and sharp, despite being small.

Unfortunately, these sharks have been captured for many years, and often times end up in fertilizer or animal foods, and sometimes even on dinner plates.
