Animals That Eat Meat & Plants | Sciencing
Animals that eat meat only are classified as carnivores, though in reality (plant- eaters), omnivores (which consume both plant and animal. People who eat meat argue that it's “natural” for humans to consume animals. But is this Humans' intestinal tracts are much longer, like those of plant-eaters. A carnivore is an animal or plant that eats the flesh of animals. Most, but not all, carnivorous animals are members of the Carnivora order; but.
Carnivora is a taxonomic grouping; that is, it lumps together species based on their relationship on the tree of life.
But a whole host of them are omnivores and some — the giant panda, for example — primarily consume vegetation. Furthermore, other mammalian orders certainly include carnivorous members; one, Cetacea whales and dolphinsis an exclusively carnivorous grouping — much more exclusively carnivorous than Carnivora, in fact.

Examples include cats felidspinnipeds, raptors birds of preysnakes, crocodilians, sharks and nearly all spiders. Facultative carnivores are those that include significant amounts of plant material in their diet.
Most dogs canidsfor example, are facultative carnivores, though gray wolves and African wild dogs painted hunting dogs are hypercarnivorous. Facultative carnivores that eat particularly large proportions of plant matter alongside meat, such as many bears, are more commonly simply called omnivores. Carnivore Adaptations Because only a small proportion — often very roughly generalized as 10 percent — of energy gets transferred up the links of a food web, an ecosystem can support many more plants primary producers, in energy or trophic terms than herbivores, and many more herbivores than carnivores.
It follows that carnivorous animals, generally speaking, must expend more energy than your average herbivore in tracking down its less-abundant food. The traps work in various ways. A Venus flytrap Dionea muscipulafor example, has hinged leaves that snap shut when trigger hairs are touched.
A pitcher plant has a pitfall trap; its leaves fold into deep pits filled with digestive enzymes. And sundews and butterworts have sticky mucus on their stalks that stops insects in their tracks.

Venus flytrap Dionaea muscipula with a trapped fly. Marco Uliana Carnivore types There are three different categories of carnivores based on the level of meat consumption: Carnivores that eat mostly meat are called hypercarnivores. The cat family, including lions, tigers and small cats, for example, are obligate carnivores, as are snakes, lizards and most amphibians. Many hypercarnivores, including some members of the Carnivora order, have heavy skulls with strong facial musculature to aid in holding prey, cutting flesh or grinding bones.
Many also have a special fourth upper molar and first lower molar. These two teeth together are called the carnassial teeth.
Carnivorous baleen whales, which have no teeth at all, use a similar strategy to strain krill from sea water. Their mouths contain rows of strong, flexible baleen plates made of keratin, the same protein that's in human fingernails.
Carnivores: Facts About Meat Eaters
Animals that depend on meat for at least 50 percent of their diet are called mesocarnivores. Along with meat, these animals will also eat fruits, vegetables and fungi. Mesocarnivores are typically small to mid-size species and often live close to human populations. Raccoons, foxes and coyotes are examples of mesocarnivores.

Hypocarnivores are carnivores that eat the least amount of meat — less than 30 percent of their diet, according to National Geographic. These animals, which can also be considered omnivores, eat fish, berries, nuts and roots, as well as meat.
Size The world's largest animal is also the world's largest carnivore. The blue whale Balaenoptera musculus grows up to feet 30 meters long and weighs up to tons metric tons.
The largest carnivore on land is the polar bear, which can weigh to 1, lbs. The smallest carnivorous mammal is the least weasel. It grows no more than 16 inches long
