Sea anemone is a kind of marine animal, their body shape and structure are quite special.In terms of specific classification, sea anemones belong to the phylum Cnidaria, so they belong to Cnidaria.In fact, Cnidaria is a relatively low level of animals, their body structure is relatively simple, not too complex body structure and organs.They don't have brains in their bodies to think effectively; In addition, they do not have advanced respiratory organs, that is, lungs.
From the point of view of feeding habits, sea anemone is a carnivore.Although the body structure of sea anemones is very simple, they are relatively efficient when hunting, because the body of sea anemones is covered with tentacles, which are distributed with some stinging cells, which can release venom, which can be used to paralyze prey around.When fish pass by, the anemones release their venom unexpectedly, and they can catch and eat the fish.
As mentioned above, the sea anemone belongs to the phylum Cnidaria, so it is a Cnidaria.In fact, the original name of Cnidaria is coelenterate, so sea anemones belong to a kind of coelenterate.As coelenterates, sea anemones also fit many of the characteristics of coelenterates.For example, in terms of body shape, most coelenterates have radially symmetrical bodies with fixed shapes, as do sea anemones.For example, coelenterates generally have stinging cells on the outside of their bodies, and sea anemones have tentacles, which are distributed with many stinging cells.Also, coelenterates are generally carnivorous, and the main food of sea anemones is meat.
