EVERYDAY SCIENCE

Detailed explanation-1: -Nocturnal animals tend to have bigger eyes and wider pupils. Their eyes have more rod cells than cone cells, and the wider pupil is able to collect more light, which enables them to see better in the dark than we can. They also have a reflective layer called tapetum behind the retina.

Detailed explanation-2: -The absence of sweat glands, and the concentration of urine are other physical adaptations made by desert animals. Because fat intensifies heat, a unique physical adaptation of some desert animals is the storage of fat in humps or tails, rather than throughout the entire body.

Detailed explanation-3: -In order to survive, prey animals rely on camouflage, warning signals, well-developed senses, weapon-like body parts, and defensive behaviors. Predators also have camouflage coloring and blend in with their surroundings, but for them the purpose is to hide when hunting prey.

Detailed explanation-4: -Sweating. People do it, and so do horses. Radiating heat. Elephants can radiate heat from their ears, which they hold out from their bodies; jackrabbits do the same thing with their long ears. Estivation. This is the opposite of hibernation. Hiding out. Panting. Shedding. Taking a dip. 07-Jul-2010
