What does a sea anemone do when it is not covered by water?

When anemones feel threatened they retreat into stumps anchored on rocks, coral or the sea bottom. Some species can survive out of water for several hours during low tide by retaining water in their body cavity.

Why do clownfish swim in anemones?

Nematocysts release toxins when a small animal contacts an anemone’s tentacle. This allows the clownfish to swim comfortably between the tentacles of anemones, creating a protected environment in which potential predators are killed off by anemone stings.

Why do clown fish rub against anemones?

Anemone tentacles sting and kill other species of fish, but the clownfish is protected from the anemone’s sting. It is believed that the clownfish is protected due to a mucus coat on the outside of its skin. They do this by rubbing themselves on the anemone’s tentacles over and over again.

How does crab breathe in water?

Crabs breathe underwater by drawing water (which contains oxygen) over their gills using an appendage called a scaphognathite, which is located on the crab’s underside, near the base of its claws. The water passes over the gills, which extract the oxygen.

Can dolphins breathe underwater?

Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. The blow is the sound you hear, and the spray of water you see, when the dolphin forcefully breathes out and clears away any water resting on top of his blowhole.

Why do clownfish live in anemones?

Why are sea anemones important to the ocean?

Sea anemones are among the most famous examples of marine life forms that exhibit symbiotic relationships in the ocean. Through mutualistic symbiosis, sea anemones benefit from clownfish, which help ward away predators, get rid of parasites, and offer nutritious waste in exchange for meal scraps and protection within the anemone’s tentacles.

Are there any sea anemones that have detachable tentacles?
