According to the country profile related to biodiversity of wildlife in Djibouti, the nation contains more than 820 species of plants, 493 species of invertebrates, 455 species of fish, 40 species of reptiles, three species of amphibians, 360 species of birds and 66 species of mammals. Wildlife of Djibouti is also listed as part of Horn of Africa biodiversity hotspot and the Red Sea and Gulf of Aden coral reef hotspot. Mammals include several species of antelope, such as Soemmerring's gazelle and Pelzeln's gazelle. As a result of the hunting ban imposed since early 1970 these species are well conserved now. Other characteristic mammals are Grevy's zebra, hamadryas baboon and Hunter's antelope. The warthog, a vulnerable species, is also found in the Day National park. The coastal waters have dugongs and Abyssinian genet; the latter needs confirmation by further studies. Green turtles and hawksbill turtles are in the coastal waters where nestling also takes place. The Northeast African cheetah ''Acinonyx jubatus soemmeringii'' is thought to be extinct in Djibouti.
