Eastern Atlantic and the Mediterranean Sea, near rocky bottoms, cliffs and reefs of the continental shelf.
Description
The dusky grouper is a robust grouper of the family Serranidae reaching about 1.5 metres. The sturdy, dark-brown body bears irregular pale blotches and has a rounded tail and thick lips. Like many groupers it is a protogynous hermaphrodite: individuals begin as females and later, as large animals, become males. The species lives sedentarily near rocky bottoms, cliffs and reefs in the eastern Atlantic and the Mediterranean, often at a fixed shelter. As an ambush predator it takes octopus, crabs, lobsters and fish. Because of its curious, site-attached nature it is vulnerable to spearfishing; through overfishing it is assessed as Vulnerable (VU).
