Excerpt: The diverse order Carnivora (pronounced /k r n v r / or sometimes / k rn v r /; from Latin car (stem carn-) "flesh," + vor re "to devour") includes over 260 species of placental mammals. Its members are formally referred to as carnivorans, while the word "carnivore" (often popularly applied to members of this group) can refer to any meat-eating animal. Carnivorans are the most diverse in size of any mammalian order, ranging from the least weasel (Mustela nivalis), at as little as 25 grams (0.88 oz) and 11 centimetres (4.3 in), to the polar bear (Ursus maritimus), which can weigh up to 1,000 kilograms (2,200 lb), to the southern elephant seal (Mirounga leonina), whose adult males weigh up to 5,000 kilograms (11,000 lb) and measure up to 6.9 metres (23 ft) in length. Cladotheria is a group of mammals that is defined as including the ancestor of Dryolestoidea, Peramuridae and living Therians plus all of its descendants. Zofia Kielan-Jaworowska, Richard L.
