Summary

Description

With its flat body, broad trunk and large, very high pectoral fins, Squatina squatina resembles a large ray more than a shark. Its skin is grey to reddish or greenish-brown and is scattered with small white spots and blackish dots. The dorsal fins have a dark leading edge and a pale trailing edge. Whisker-like nasal barbels project from near the nostrils. The monkfish, or angelfish as it is sometimes known, has large, round eyes with vertical slit pupils. It can grow up to 1.8 m in length and 80 kg in weight.

Recorded distribution in Britain and Ireland

Expected distribution all around the offshore coast of Ireland and Britain as far north as the Shetland Isles and as far south as southern Ireland.
