The diverse order Carnivora (IPA: /ˈkɑː(ɹ)nɪˌvɔːɹə/ or /kɑː(ɹ)ˈnɪvəɹə/; from Latin carō (stem carn-) 'flesh', + vorāre 'to devour') includes over 260 species of placental mammals. Members of the order are often called "carnivores", but the word "carnivore" can also refer to a meat-eating animal of any type. While the Giant Panda is almost exclusively an herbivore (it occasionally eats fish, eggs and insects), nearly all others eat meat as their primary diet item: some (like the cat family) almost exclusively, others (like the bears and foxes) are more omnivorous. Carnivorans are the most diverse in size of any mammalian order, ranging from the Least Weasel (Mustela nivalis), at as little as 25 grams and 11 cm (4.3 in), to the Polar bear ((Ursus maritimus)), which can weigh up to 1000 kg (2200 lb), to the Southern Elephant Seal, adult males of which average 2,270 kg (5,000 lb) and measure 4.2 m (13.9 ft) (and may grow considerably larger).
