This Hot-Tempered Sea Fish Has a Wider Mouth Than Body (Pics & Video)

Discovered in 1858, this ultra-aggressive little guy grows only to about 30 centimetres (12 inches) in length with a long and slender body, large pectoral fins and much smaller pelvic fins. It lives in the pacific waters, off the coast of North America – from San Francisco, USA to Baja California in Mexico. Sarcastic fringeheads are ambush predators, which means they tend to stake out a hidey hole that offers them both protection and a vantage point from where to pounce on prey. Once they've reverse parked into their chosen nook, they'll aggressively charge at anything that comes too near – including divers. And according to the survivors, they don't like to let go.
