Lactophrys is a genus of boxfishes native to the western Atlantic Ocean. All trunkfish of the genus Lactophrys, secretes a colorless toxin from glands on its skin when touched. The toxin is only dangerous when ingested, so there is no immediate harm to divers. Predators however, as large as nurse sharks, can die as a result of eating a trunkfish.
