Description

The least puffer (Sphoeroides parvus) is a small pufferfish of the family Tetraodontidae from the western Atlantic. The species has a stocky body with a brownish, mottled pattern and reaches about 15 cm. It inhabits shallow, turbid coastal waters and estuaries over soft bottoms. Like other puffers it can inflate when threatened and its tissue contains the potent poison tetrodotoxin; consumption without proper knowledge is life-threatening. With its powerful incisor teeth it crushes crustaceans and mollusks. Owing to its small size and toxicity the species is of limited fishery importance.
