The Ostracioidei are marine fishes that have the body almost entirely encased in a rigid carapace of enlarged scale plates (Matsuura 2015).
Characters (from Matsuura 2015): Body almost completely encased in bony shell or carapace formed of enlarged, thickened scale plates, usually hexagonal in shape and firmly sutured to one another; carapace with openings for mouth, eyes, gill slit, pectoral, dorsal, and anal fins, and for flexible caudal peduncle; scale plates often with surface granulations, may be prolonged into prominent carapace spines over eyes or along ventrolateral or dorsolateral angles of body; mouth small, terminal, with fleshy lips; teeth of moderate size, conical, usually fewer than 15 in each jaw; gill opening moderately short, vertical to oblique slit in front of pectoral-fin base; spinous dorsal fin absent; most dorsal-, anal-, and pectoral-fin rays branched; caudal fin with eight or nine branched rays; pelvic fins absent.
