The hexagonal plate-like scales of these fish are fused together into a solid, triangular, box-like carapace, from which the fins and tail protrude.

Young boxfishes are more round in shape and may exhibit bright colors. Because of their body scale structure, boxfish are limited to slow movements.

The boxfish are a family, ostraciidae, of squared, bony fish belonging to the order tetraodontiformes – closely related to the pufferfish and filefish. They come in a variety of different colors, notable for the hexagonal or “honeycomb” patterns in their skin and skeletons. They swim in a rowing manner. Fish in the family are known variously as boxfish, cofferfish, cowfish and trunkfish.
