Here's why:
* Sessile Animals: Some animals are sessile, meaning they stay in one place for their entire lives. Examples include:
* Barnacles: They attach themselves to rocks, boats, and other surfaces in the ocean.
* Corals: They build colonies and live in one spot.
* Sponges: They filter food from the water and remain fixed to a surface.
* Parasitic Animals: Some animals are parasitic, meaning they live inside or on other animals and rely on them for food and shelter. They may not have the ability to move independently. Examples include:
* Tapeworms: Live inside the intestines of animals and absorb nutrients.
* Ticks: Attach themselves to animals and suck their blood.
* Fleas: Live on the skin of animals and feed on their blood.
While most animals do move from place to place, there are exceptions. The ability to move is just one characteristic of animal life.
