anatomy
The small blacktip shark is a 1.5 to 2.5 m tall shark with a long, pointed snout. The beginning of the first dorsal fin is level with or slightly behind the attachment of the pelvic fins. The color is dark gray on the back and whitish on the belly. All fins except the anal fin are darkly colored at the tips.

The habitat is from the surface to a depth of around 30 meters, partly also in river mouths. Widespread in tropical and subtropical seas:
- western Atlantic (Massachusetts to southern Brazil),
- Eastern Atlantic (Canary Islands to Zaire),
- western Mediterranean,
- Indian Ocean (South Africa via India to Thailand and Australia),
- western Pacific (Philippines, China) and
- eastern Pacific (California to Peru), as well as Hawaii, Tahiti and Galapagos Islands.

In addition to sexual reproduction , this species of shark also has the ability to reproduce by means of virgin generation . The small blacktip shark is not the only type of shark that is able to reproduce parthenogenetically: single-sex reproduction has also been demonstrated in the hammerhead shark .
