Animals in the mammalian class, including elephants, dogs, cats, apes, bats, sloths, lemurs, horses and beavers, have sweat glands and sweat through either their eccrine, their apocrine sweat glands or both. Primate mammals, such as apes, gorillas and humans, have eccrine sweat glands all over their bodies. Non-primate mammals, such as dogs and cats, have apocrine glands on their paws and feet that help to cool them off.Know More
Whole body cooling through sweating and evaporation is most effective among humans but is also observed among apes and catarrhine primates, or Old World monkeys. Non-human, hairy primates, such as the gorilla and chimpanzee, sweat through their armpits, palms of their hands and soles of their feet. Contrary to popular belief, pigs, rhinos and hippos, like other warm-blooded mammals, do have sweat glands. They pass sweat through passive diffusion, which is ineffective for cooling their bodies. They cool off by wallowing in cool water or mud, which has the same cooling effect as sweating.
Most non-primate mammals have apocrine sweat glands on their hair follicles. The glands secrete an oily, opaque and colorless liquid that gains a foul odor upon bacterial decomposition. The apocrine sweat gland is also called the scent gland as it is not as effective for cooling as the eccrine sweat gland. In humans, these glands can be found on the armpit and perianal areas.Learn more in Zoology
Animals that achieve true hibernation, which is an inactive, near-death state characterized by low body temperature and slow heart rate and breathing, include bats, hedgehogs and certain species of rodents such as ground squirrels, hamsters, marmots and hazel mice. Animals that achieve a less intense state of dormancy that is commonly called hibernation include bears and other mammals, as well as various species of reptiles, amphibians and fish.Full Answer >
Animals that consume algae include fish, salamanders, newts, frogs and bacteria. Algae, a type of aquatic plant, provides food and nutrition for many creatures. It exists in marine habitats such as oceans and lakes, and appears in ponds, rivers and other freshwater environments.Full Answer >
Animals that eat only plants are known as herbivores. These animals eat a variety of plants and seeds to obtain both nutrition and energy. Examples of herbivores include grasshoppers, deer and rabbits.Full Answer >
Animals in the order Artiodactyla, or even-toed ungulates, include deer, antelope, giraffes, camels, llamas, hippopotamuses, pigs, cattle, sheep and goats. These are mammals whose third and fourth toes carry their weight, rather than the third toe only, as with horses.Full Answer >
