The pictures were taken at the Avalon Pier in Kill Devil Hills around 445Pm. I stopped at the pier to check out the rip current and wave situation, given that it was coming on low tide. I noticed the yellow rod bent over and some commotion on the end of the pier.
According to a NOAA "Fish Fact Sheet:"
Black tip sharks are one of the most common shark species found inshore off the coast of Florida. Although the majority of shark bites in Florida are likely attributable to this species, there has never been a fatal attack credited to this species in this region.
Scientific name: Carcharhinus limbatus
Distribution: Off the east coast of the United States black tip sharks range from New England to Mexico but are most commonly found between North Carolina and Texas, especially in spring and summer.
Habitat: This shark inhabits shallow coastal waters and estuaries and offshore surface waters. Black tip sharks use shallow inshore waters from South Carolina to Texas as nursery areas for their pups in spring and summer. They can be found in groups as young or adults feeding in shallow water.
Life history: This species is a relatively fast growing shark, reaching maturity at about 4-5 years of age and living longer than 10 years. Number of pups per litter is usually 4 to 6. Maximum size of black tips off the U.S. eastern seaboard is about 6 feet in length
Management: In the Atlantic, black tip sharks are part of the large coastal shark management group, which is overfished; commercial and recreational fishing regulations are in place for this species.
