Mammals are vertebrate animals characterized by the production of milk in females for the nourishment of young and endothermic or "warm-blooded" bodies. Mammals encompass some 5,500 species (including humans), distributed in about 1,200 genera, 152 families and up to 46 orders. The vast majority of mammals have seven cervical vertebrae (bones in the neck), including bats, giraffes, whales, and humans. They possess a neocortex — is a brain region that is unique to mammals.
