how many different species of hedgehogs are there
Hedgehog A hedgehog is any of the spiny mammals of the subfamily Erinaceinae, in the eulipotyphlan family Erinaceidae. There are seventeen species of hedgehog in five genera, found through parts of Europe, Asia, and Africa, and in New Zealand by introduction. There are no hedgehogs native to Australia, and no living species native to the Americas (the extinct genus Amphechinus was once present in North America). Hedgehogs share distant ancestry with shrews (family Soricidae), with gymnures possibly being the intermediate link, and have changed little over the last 15 million years.[2] Like many of the first mammals, they have adapted to a nocturnal way of life.[3] Hedgehogs' spiny protection resembles that of the unrelated porcupines, which are rodents, and echidnas, a type of monotreme.
Western black rhinoceros The western black rhinoceros (Diceros bicornis longipes) or West African black rhinoceros was a subspecies of the black rhinoceros, declared extinct by the IUCN in 2011.[1][2] The western black rhinoceros was believed to have been genetically different from other rhino subspecies.[3] It was once widespread in the savanna of sub-Saharan Africa, but its numbers declined due to poaching. The western black rhinoceros resided primarily in Cameroon, but surveys since 2006 have failed to locate any individuals.
