What is the common name of Ginglymostoma cirratum?
Answer
Nurse shark
The common name of Ginglymostoma cirratum is the nurse shark.
This species is a carpet shark in the family Ginglymostomatidae, found mainly in warm coastal waters of the western Atlantic and eastern Pacific. Its broad head, flattened body, small eyes, two barbels, and long tail reflect a life spent resting on or near the seafloor. Unlike fast-swimming open-water predators, nurse sharks often shelter beneath ledges during the day and forage at night.
The name “nurse shark” has an uncertain history. One explanation connects it to old words such as “huss” or “hurse,” once used for dogfish and other sharks; another links it to the species’ unusual reproductive biology. The scientific genus name Ginglymostoma comes from Greek words associated with a hinged mouth.
Nurse sharks are generally docile, but that does not make them harmless. They can deliver powerful suction-feeding bites if handled, stepped on, or harassed. They are also sometimes confused with other carpet sharks, including the tawny nurse shark and whale shark, which belong to different species and genera.
