The lion is another keystone species. Keystone mutualists are organisms that participate in mutually beneficial interaction and the loss of which would have a profound impact upon
Masai giraffe of Herr von Tippelskirch who was a member of a German scientific expedition in German East Africa to what is now northern Tanzania in 1896. Tippelskirch brought back the skin of a female Masai giraffe from near Lake Eyasi which was later on identified as "Giraffa tippelskirchi". The Masai giraffe is distinguished by jagged spots on its body, geographic range including southern Kenya, all of Tanzania, and the Luangwa Valley in Zambia, and genetic evidence. It is the largest-bodied giraffe species, making it the tallest land animal on earth. All giraffes are considered vulnerable to extinction by the IUCN, and
