1. DEFINITION OF mammals
A warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, females that secrete milk for the nourishment of the young, and (typically) the birth of live young.
2. BASIC FACTS
Assumed to originate from a line that diverged away from the reptiles about 300 million years ago.
Different species of mammals have evolved to live in nearly all terrestrial and aquatic habitats on Earth. Mammals inhabit every terrestrial biome, from deserts to tropical rainforests to polar icecaps. Many species are arboreal, spending most or all of their time in the forest canopy.
It is estimated that the total number of wild mammals in the world is about 130 billion. The mammal with the highest population is cows, estimated at around 1.5 billion.
The smallest mammal is the Kitti's hog-nosed bat with a length of about 1.1 to 1.3 inches (29 to 33 mm) and weighing less than 0.07 oz (2 g). The largest mammal is the Blue Whale at 98 feet (30 m) in length and 200 short tons (180 metric tons) or more in weight.
Lifespan ranges from a year or two in some rodents, to over 150 years for certain species of whale.
Most mammals are viviparous, giving birth to live young. However, the species of monotreme, the platypuses and the echidnas, lay eggs.
Between 12 to 13 days for the Opossum, to about 640 to 660 days (or roughly 95 weeks) for Elephants.
The diets of mammals span across all three main dietary groups: herbivores, carnivores and omnivores.
