Nurse Sharks

The Ginglymostomatidae are a cosmopolitan family of carpet sharks known as nurse sharks, containing four species in three genera. Common in shallow, tropical, and subtropical waters, these sharks are sluggish and docile bottom dwellers. They are the most abundant species of shark found in shallow coastal waters. Nurse sharks typically attack humans only if directly threatened.

The name nurse shark is thought to be a corruption of nusse, a name which once referred to the catsharks of the family Scyliorhinidae. The nurse shark family name, Ginglymostomatidae, derives from the Ancient Greek words γίγγλυμος (gínglumos), meaning "hinge", and στόμα (stóma), meaning "mouth".
