SandperchPinguipedidae

Sandperches (Pinguipedidae) are benthic fish characterized by elongated bodies that taper towards the head and are slightly flattened towards the rear. They have long dorsal and anal fins, each supported by a few spines, and enlarged lips armed with prominent canine teeth. Their eyes are positioned high on the head, and body patterns often feature distinctive spots and bands. Most species found in the 🌊 Red Sea typically measure 15-30 cm (6-12 in) in length, with some individuals growing to over 40 cm (16 in).

These fish inhabit sand or rubble substrates, frequently near reef edges, at depths ranging from shallow waters down to about 60 m (200 ft). They commonly rest on the seabed, propped up on their widely spaced pelvic fins, waiting to ambush small benthic invertebrates and fish. Among Sandperches, some species exhibit protogynous hermaphroditism, maturing first as females before undergoing a sex change to male, a process often accompanied by notable differences in colouration between sexes.
