The richness and variety of the wildlife of Ethiopia is dictated by the great diversity of terrain with wide variations in climate, soils, natural vegetation and settlement patterns.
Ethiopia contains a vast highland complex of mountains and dissected plateaus divided by the Great Rift Valley, which runs generally southwest to northeast and is surrounded by lowlands, steppes, or semi-desert.
Ethiopia is an ecologically diverse country, ranging from the deserts along the eastern border to the tropical forests in the south to extensive Afromontane in the northern and southwestern parts.
The nation is a land of geographical contrasts, ranging from the vast fertile west, with its forests and numerous rivers, to the world's hottest settlement of Dallol in its north.
These include primitive bichirs, lung fishes, catfish, cyprinids, cyprinodonts, cichlids, several caracins and a few spiny rayed families.
The following fish families are most peculiar of this region: Historically, throughout the African continent, wildlife populations have been rapidly declining owing to logging, civil wars, hunting, pollution, poaching and other human interference.
Human impact threatens many species, with greater threats expected as a result of climate change-induced by greenhouse gas emissions.
