Anglerfish

Description

Lophius piscatorius,commonly known as the angler,is a monkfish in the family Lophiidae.It is found in coastal waters of the northeast Atlantic,from the Barents Sea to the Strait of Gibraltar,the Mediterranean and the Black Sea.Within some of its range,including the Irish Sea,this species comprises a significant commercial fishery.It has a very large head which is broad,flat,and depressed;the rest of the body appears to be a mere appendage.The wide mouth extends all the way around the anterior circumference of the head,and both jaws are armed with bands of long,pointed teeth.These are inclined inwards,and can be closed so as to offer no impediment to an object gliding towards the stomach,but to prevent its escape from the mouth.The pectoral and pelvic fins are so articulated as to perform the functions of feet,so the fish is able to walk along the bottom of the sea,where it generally hides itself in the sand or amongst seaweed.Around its head and also along the body,the skin bears fringed appendages resembling short fronds of seaweed,a structure which,combined with the extraordinary faculty of assimilating the colour of the body to its surroundings,assists this fish greatly in camouflaging itself in the places which it selects on account of the abundance of prey.It has no scales.
