Carnivorans are a taxonomic order within the class Mammalia. They are one of the largest orders of mammals, with over 280 living species. Carnivorans are found on all continents except Antarctica. They range in size from the smallest carnivoran, the least weasel, which weighs only about 100 grams, to the largest carnivoran, the polar bear, which can weigh over 1,500 kilograms.
Carnivorans are typically predators, although some species, such as the giant panda and red panda, are herbivorous. Carnivorans have a variety of adaptations that help them to hunt and eat meat. These adaptations include sharp teeth and claws, strong jaws, and a digestive system that is designed to process meat.
Carnivorans play an important role in ecosystems. They help to control the populations of other animals, including herbivores and omnivores. This can help to maintain the balance of ecosystems and prevent overpopulation. Carnivorans are also important for the cycling of nutrients. When they eat meat, they consume the nutrients that are stored in the tissues of their prey. These nutrients are then released back into the environment through the carnivore's urine and feces.
Carnivorans are a diverse and fascinating group of mammals. They play an important role in ecosystems and are a part of our natural world.
