Eritrea is a country in the Horn of Africa region of Eastern Africa. It is bordered by Ethiopia in the south, Sudan in the west, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately 117,600 km2, and includes the Dahlak Archipelago and several of the Hanish Islands.
Eritrea has several species of mammals and a rich avifauna of 560 species of birds.
Eritrea is home to an abundant amount of big game species. Enforced regulations have helped in steadily increasing their numbers throughout Eritrea. Mammals commonly seen today include the Abyssinian hare, African wild cat, Black-backed jackal, African golden wolf, Genet, Ground squirrel, pale fox, Soemmerring's gazelle, warthog. Dorcas gazelle are common on the coastal plains and in Gash-Barka.
Lions are said to inhabit the mountains of the Gash-Barka Region. There is also a small population of African bush elephants that roam in some parts of the country. Dik-diks can also be found in many areas. The endangered African wild ass can be seen in Denakalia Region. Other local wildlife include bushbuck, duikers, greater kudu, Klipspringer, African leopards, oryx and crocodiles. The spotted hyena is widespread and fairly common. Between 1955 and 2001 there were no reported sightings of elephant herds, and they are thought to have fallen victim to the war of independence. In December 2001 a herd of about 30, including 10 juveniles, was observed in the vicinity of the Gash River. The elephants seemed to have formed a symbiotic relationship with olive baboons, with the baboons using the water holes dug by the elephants, while the elephants use the tree-top baboons as an early warning system.
It is estimated that there are around 100 African bush elephant left in Eritrea, the most northerly of East Africa's elephants. The endangered African wild dog was previously found in Eritrea, but is now deemed extirpated from the entire country. In Gash-Barka, snakes like saw-scaled viper are common. Puff adder and red spitting cobra are widespread and can be found even in the highlands. In the coastal areas marine species that are common include dolphin, dugong, whale shark, turtles, marlin, swordfish, and manta ray.
