Description

The smallspine turretfish is a boxfish (Ostraciidae) from shallow reef and seagrass water of the Indo-West Pacific. The species grows to about 12 cm and has a rigid, box-shaped, yellow-brown armour of fused bony plates, triangular in cross-section, with small spines on the back. With that stiff box it swims slowly with waving fins and snaps at small invertebrates, worms and algae. Under stress its skin can release a toxin, but by touch it is not seriously harmful to humans.
