Houtman Abrolhos
The Houtman Abrolhos is unusual in having a luxuriant and diverse living coral reef at such a high latitude. 194 species in 50 genera have been recorded there, all but two of which are tropical. This is a surprisingly high coral diversity, considering the high latitude of the reef, and the relatively low diversity of other biota. For a full list, see list of corals of the Houtman Abrolhos.
Horn of Africa
The Horn of Africa holds more endemic reptiles than any other region in Africa, with over 285 species total and about 90 species which are found exclusively in the region. Among endemic reptile genera, there are "Haackgreerius", "Haemodracon", "Ditypophis", "Pachycalamus" and "Aeluroglena". Half of these genera are uniquely found on Socotra. Unlike reptiles, amphibians are poorly represented in the region.
