2.The two main adaptations that desert animals must make are how to deal with lack of water and how to deal with extremes in temperature. ... Since water is so scarce, most desert animals get their water from the food they eat: succulent plants, seeds, or the blood and body tissues of their prey.
3.Aestivation and hibernation are the types of sleeping pattern. The main difference between aestivation and hibernation is, aestivation is summer sleep while hibernation is winter sleep in which an organism passes the winter period in dormant condition. Aestivation: ... They take sleep during the hot hours of daytime.
4.Aquatic animals also have adaptations to regulate temperature, since water transfers heat faster than air. Sea otters use a layer of air pockets combined with oily fur to stay warm. Oxygen is transferred from water through organs called gills in fish, sharks, and rays.
5.The bodies of birds are adapted for flying. Many of a bird's bones are hollow which makes birds' bodies lightweight. Flying birds have large chest muscles that move the wings. Birds have feathers that help them fly.
6.Herbivores : Animals like cows , buffaloes , sheep etc., that eat plants. Carnivores : Animals like lions, tigers, etc., that prey on and eat other animals. Omnivores : Animals like bears, crows etc., that eat both plants and animals.
7.Lions and tigers are carnivores (meat-eaters). They have long, pointed teeth to grip their prey and sharp teeth for cutting up meat. These animals do not have flat chewing teeth because they swallow their food in chunks.
8.Many large carnivores that hunt regularly, such as hyenas and jackals, but also animals rarely thought of as scavengers, such as African lions, leopards, and wolves will scavenge if given the chance.
9.A few examples of parasites are tapeworms, fleas, and barnacles. Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans. They get food by eating the host's partly digested food, depriving the host of nutrients.
10.The disguising of military personnel, equipment, and installations by painting or covering them to make them blend in with their surroundings.
11.Clams protect themselves by closing up their shells. Porcupines, porcupine fish and starfish have spines on the surface of their body. The spines can injure enemies that go near or attack these animals. ... This makes it easier for these animals to hide from their enemies.
