Map Of The Smoothtooth Blacktip Shark’s Habitat

Smoothtooth Blacktip Shark Habitat Map

The smoothtooth blacktip shark lives in two specific locations – eastern Yemen and Kuwait, 1900 miles apart. In Yemen, it dwells in the Gulf of Aden with a narrow continental shelf 1.6 miles deep cut off from freshwater sources. At the same time, in Kuwait, they live in the Persian Gulf, which is shallow (130 ft) and connected to the Tigris-Euphrates-Karun river system giving it a source of fresh water.

Their habitats are varied from estuaries to coral reefs, which are mostly shallow.



Smoothtooth blacktip sharks feed mainly on marine catfish but also consume small bony fish.


They are viviparous, giving live birth to pups. These sharks become sexually mature between 3 and 3.9 feet long.

Interactions with humans

The IUCN classifies this shark as “Endangered” or “EN” due to its small range and population. As the waters in the Arabian Peninsula are subject to heavy fishing, these sharks are often caught as bycatch.
