Most terrestrial animals crawl. Crawling is the characteristic mode of locomotion for most reptiles, amphibians and mammals. Insects generally crawl when they aren't flying, and terrestrial molluscs, such as snails and slugs, crawl on a single, specialized foot.Know More
Newts and salamanders crawl, as do frogs and toads when they aren't hopping. Lizards crawl with a characteristic side-to-side motion that is replicated by their close relatives the snakes. Birds generally do not crawl, though some penguins slide on their bellies for high-speed and long-distance travel. Most terrestrial invertebrates crawl, and even flying species, such as flies, moths and bees, usually revert to a stepwise, six-legged locomotion to move efficiently across surfaces.
Some animals crawl at various stages of life, but not at others. Humans, for example, typically crawl in infancy and can revert to all fours when the situation calls for it, but this is slow and inefficient relative to the adults' normal upright posture.
Many terrestrial animals have ways of moving apart from crawling, such as the horse's gallop or trot and the adult human's bipedal walk, but crawling on four, six or eight legs is common. Some animals can also form a ball and roll, such as the pangolin.Learn More

The snowy owl of the Arctic tundra has thick feathers to keep it warm when temperatures are extremely low. These birds live year-round in Alaska, Canada, northern Europe, Russia and Greenland. However, snowy owls can sometimes travel to southern Canada or the northern United States if winter prey is scarce.Full Answer >

Some examples of predator-prey relationships are lion-cape buffalo, tiger-deer, snake-frog, python-rabbit, bear-fish and cheetah-gazelle. Predator-prey relationships exist in all habitats and ecosystems. An eagle hunts smaller birds such as pigeons and swallows. An orca hunts seals and walruses in the sea.Full Answer >
