The Yellow boxfish (Ostracion cubicus) is a saltwater fish of the family Ostraciidae that grows up to 45 cm.
Description
The yellow boxfish is a striking reef fish of the boxfish family (Ostraciidae) from the Indo-Pacific. The species grows to about 45 cm and has a nearly cube-shaped, bony-plated body; juveniles are bright yellow with black spots, while adults become duller yellow-brown to blue-grey. It inhabits coral and rocky reefs and moves slowly with its pectoral and dorsal fins. As an omnivore it eats algae, sponges, small invertebrates and worms. When stressed the skin secretes a toxin (pahutoxin) that can kill other fishes in an enclosed space; for this reason the species is not eaten. When handled it is harmless to humans.
