Members of this family occur in a variety of different colors, and are notable for the hexagonal or "honeycomb" patterns on their skin. They swim in a rowing manner. Their hexagonal plate-like scales are fused together into a solid, triangular or box-like carapace, from which the fins, tail, eyes and mouth protrude. Because of these heavy armoured scales, Ostraciidae are limited to slow movements, but few other fish are able to eat the adults. Ostraciid boxfish of the genus Lactophrys also secrete poisons from their skin into the surrounding water, further protecting them from predation. Although the adults are in general quite square in shape, young Ostraciidae are more rounded. The young often exhibit brighter colors than the adults. Ostraciids occur in the Atlantic, Indian, and Pacific oceans, generally at middle latitudes, although the common or buffalo trunkfish (Lactophrys trigonus) which lives mainly in Florida waters may be found as far north as Cape Cod. The scrawled cowfish, Acanthostracion quadricornis, can grow up to 50 centimetres (20 in) in length, but is generally smaller at higher latitudes. The various members of this family are able to secrete cationic surfactants through their skin which can act as a chemical defense mechanism. An example of this is pahutoxin, a water-soluble, crystalline chemical toxin that is contained in mucus secreted from the skin of Ostracion lentiginosus and other members of the trunkfish family when they are under str...
