Commonly found in the waters of North Carolina, Spinner Sharks are born measuring between 24 and 30 inches. Males typically mature at around 4 feet, while females reach sexual maturity at about 5 feet, with the average size being 6.4 feet. These sharks have a lifespan of 11 to 20 years, and the largest recorded Spinner Shark reached an impressive length of 9.1 feet.
Spinner Sharks inhabit subtropical, tropical, and temperate regions, living in both inshore and offshore waters across continental and insular shelves, extending from Cape Cod to Brazil at depths ranging from 0 to 328 feet. They migrate inshore during the spring and summer months to feed and reproduce.
With their extensive range, Spinner Sharks have a diverse diet, preying on various species including ladyfishes, sardines, herrings, anchovies, sea catfishes, lizardfishes, mullets, bluefishes, tunas, bonitos, croakers, jacks, mojarras, grunts, tongue-soles, squids, octopuses, cuttlefishes, rays, other sharks, and carrion.
After a gestation period of 11 to 15 months, Spinner Sharks give birth during the summer in inshore waters, typically delivering litters of 3 to 20 pups, although litters of 7 to 11 are more common. While noted for being involved in 16 reported shark bites, Spinner Sharks have not caused any human fatalities.
As of February 11, 2020, Spinner Sharks are classified as vulnerable due to the threats posed by bycatch and overfishing. In North Carolina, regulations allow fishermen to harvest more than 55 individuals of this species on each vessel per trip throughout the year with no minimum size limit.
