Nurse sharks grow to a length of about 14 ft. It is a rather sluggish, bottom-dwelling shark and although large does not attack humans. It has a stout body and a wide head with prominent barbels. Its pectoral fins (the fins on the sides of its body just behind the gills) are muscular and flexible and can be used to help it clamber along the bottom of the sea. Most fish, even sharks, need to be in motion to breath. The nurse shark however, can remain still while resting on the sea floor and facing against the flow of the water by pumping the water through the mouth and gills.

Nurse shark diets consist of bottom-dwelling animals like fish, squid, shrimp, crabs, sea snails, octopus, lobster, sea urchin and coral. It cannot feed on large prey because it has a small mouth. It feeds by sucking the prey into its mouth. Suction-feeding also helps it to extract prey that is hiding in holes or crevices out of their hiding spot. It can also pull out snails from their shells by sucking. The barbels of the nurse shark help it to detect potential prey.





 

The female shark gives birth to around 30 pups at a time. Nurse sharks are ovoviviparous – meaning – the pups hatch from eggs within the shark’s body and live babies are born.
