Here are some examples of sessile animals:
* Sponges: These filter feeders are attached to rocks, coral, or other surfaces.
* Barnacles: These crustaceans are attached to rocks, boats, and other surfaces.
* Corals: These colonial animals are attached to the seafloor.
* Oysters: These mollusks are attached to rocks, reefs, and other surfaces.
* Sea anemones: These cnidarians are attached to rocks, coral, and other surfaces.
Sessile animals have evolved a variety of adaptations to survive in their stationary lifestyle. For example, they may have specialized feeding mechanisms to capture food that comes to them, or they may have strong attachments to resist currents or waves.
