Characteristics


These sharks have a black edge to their caudal and pectoral fins. They appear grey from a distance, but actually have a bronze tint to their skin.

Behavior


Grey reef sharks do not pose a threat to humans, but have been inquisitive around divers. If there is food in the water, this shark will become very active and even aggressive. The expected lifespan is estimated to be at least 25 years. When threatened, the Grey reef shark will arch its body up and move its head slowly from side to side while swimming. This is thought to be a way of intimidating unwanted company. If it goes ignored, the shark may attack.

Reproduction


Grey reef sharks are viviparous (give birth to live young). The female can birth up to six pups at a time after a gestation of one year. Females are capable of storing sperm until an egg is released. After the babies are born, they are left to feed and protect themselves.
