Giraffe|Twiga(Giraffa camelopardalis)
Giraffes are the tallest mammals in the world. Despite their size, giraffes like humans have only seven neck vertebrae.
There are Masai Giraffe(Giraffa camelopardalis tippelskirchi) Reticulated Giraffe (Giraffa camelopardalis reticulata) and Rothschild's Giraffe (Giraffa camelopardalis rothschildi)
Giraffe are diurnal and nocturnal and usually found in parties of 5-20 individuals. Though giraffe are gregarious they rarely interact with another and do not form bonds.
Instead of defending a territory, adolescent males establish a dominance hierarchy by a ritualized form of fighting called "necking".
Females do not form a dominance hierarchy and do not 'neck'.
Bulls test females for oestrus by inducing them to urinate, then collecting a sample in their mouth and curling their upper lip to help them analyze the hormone content and determine if female is read to mate.
Giraffes are ruminants, browsing on trees and bushes particularly on acacia leaves, pods and soft thorns using upper lip and 45-50cm prehensile tongue to reach among the foliage.
