***Marine Mondays*** The frill shark, first scientifically recognised in 1879, dates back to the Late Cretaceous (100.5–66 Ma) is one of the oldest species in the world and often referred to as living fossils. Found at depths of 1500 m in the Pacific Ocean, this shark is mainly found as by catch. It was first observed in its natural habitat in 2004 by the ROV Johnson Sea Link II. They can grow up to 2 m and have 25 rows of sharp teeth. Unlike other sharks, frilled sharks bend their body when they are about to catch their prey, seeming almost snake-like in the water.Their long jaws are highly distensible, allowing them to swallow whole prey over more than half its size. The frilled shark is seldom encountered alive. It doesnt pose a danger to humans although scientists have accidentally cut themselves examining its teeth :) #MarineMondays
