FAMILY PERISTEDIIDAE

ARMORED SEA-ROBINS ARMORED-GURNARDS

Sea Robins are bottom fishes that live at moderate depths in tropical and temperate areas. As with the related Gurnards (Triglidae) sea robins “walk” on the sand and mud bottoms using the lower two rays of their pectoral fins. Members of this family have the head and body flattened below and completely covered in a heavy armor of bony plates and spines. The snout is extended in a bony two-pointed rostrum and there are barbels below the lower jaw. The dorsal fin is divided into spiny and soft parts; the pectoral fin has a main fin (11-13) plus 2 free rays below; the anal fin has no spines; the pelvic fins are wide apart, below base of pectorals, with I, 5 rays.

There are four genera and about 40 known species in the family. In our area there is one circumglobal genus with four endemic species, two of which enter shallow water.
