Euprotomicrus bispinatus

WHAT TO LOOK FOR

This is thought (at present) to be the smallest shark in the sea. It is a tiny, cylindrical shark with a bulbous snout, large eyes, and luminous organs on the underside of its body. Its gill slits are tiny and it has low lateral keels on its caudal peduncle. The shark has a tiny flaglike first dorsal fin which is a quarter of the length of their second dorsal fin. Its caudal fin is nearly symmetrical and paddle-shaped,
