Mammal Meaning and Definition in Wikipedia


Mammals are the group of vertebrate animals which form the class Mammalia. They have fur and a very precise kind of temperature regulation. The females bear live young, and produce milk for the young. Parental care of the young is universal among mammals, and it is essential because live birth limits the number of offspring.

Most marsupial and eutherian mammals have a reproductive cycle known as the oestrous cycle (U.S: estrous cycle). Females are sexually active only during the oestrous stage, when they are 'on heat' for a few days each month. If an ovum is not fertilised, the endometrium (uterus lining) is resorbed. Oestrus cycles may occur once or twice a year, or many times a year. Each group of mammals has its own frequency.
