The spotted trunkfish (Lactophrys bicaudalis) is a member of a family of fishes known as Ostraciidae. This group also includes boxfishes, cofferfishes, and cowfishes. The spotted trunkfish is found in coral reefs throughout the Pacific and Indian oceans, the Caribbean Sea, and the south eastern Atlantic Ocean. This species secretes a colorless toxin from glands on its skin. The toxin is only dangerous when ingested, and predators as large as sharks can die as a result of eating a trunkfish. It grows to a length of 12 inches (30 cm).
