Sandperches are members of Pinguipedidae family. They live mainly on open sedimentary or rubble bottoms, some in the vicinity of reefs, others on mud substrata. They usually rest upon the bottom, propping themselves on their pelvic fins. They can be recognized by having elongate, with a long dorsal fin with 4 or 5 spines and 20 to 24 soft rays. Their pelvic fin insertion is below or before pectoral base. Most sandperches are distinctively though rarely brightly coloured.
All sandperches are carnivorous, feeding principally on benthic crustaceans, especially crabs and shrimps, occasionally on small fishes. They are easily approached, in general, underwater.
There are 7 genera and about 90 species of sandperches worldwide. Malaysia has 2 genera and about 10 species.
