What to know about oceanic blacktip sharks
A clean field guide focused on habitat, identification, behavior, and conservation context without burying the useful parts.
The blacktip shark (Carcharhinus limbatus) is a requiem shark common in tropical and subtropical coastal and brackish waters worldwide. It has a stout, fusiform body, pointed snout, long gill slits, and no ridge between the dorsal fins. Most individuals show black tips or edges on the pectoral, dorsal, pelvic, and caudal fins and usually reach about 1.5 m (4.9 ft). Blacktip sharks are swift, energetic piscivores known to make spinning leaps out of the water while attacking schools of small fish. Both juveniles and adults form groups of varying size. They are viviparous; females typically give birth to one to ten pups every other year. Young spend their first months in shallow nurseries, and females often return to their natal nurseries to give birth. In the absence of males, females are capable of asexual reproduction. Normally wary of humans, they can become aggressive when food is present and have been involved in a number of attacks on people. The species is of commercial and recreational importance for meat, skin, fins, and liver oil.
Assessed as Vulnerable due to low reproductive rate combined with high value to fisheries leading to substantial exploitation.
