EVERYDAY SCIENCE

Detailed explanation-1: -All animals are motile (i.e., they can move spontaneously and independently at some point in their lives) and their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their lives.

Detailed explanation-2: -Although all animals can move, not all locomote or displace the body over a distance. Locomotion serves the animal in finding food and mates and in escaping predators or unsuitable habitats.

Detailed explanation-3: -All animals can move, at least during some stage of their l ife cycle . Muscles and nerves work together to allow movement. Being able to move lets animals actively search for food and mates. It also helps them escape from predators.

Detailed explanation-4: -Motile marine animals are commonly called free-swimming, and motile non-parasitic organisms are called free-living. Motility includes an organism’s ability to move food through its digestive tract. There are two types of intestinal motility – peristalsis and segmentation.
