Common Marine Animals – Sea Anemones

Sea anemones (Actiniaria) are long-dwelling, carnivorous animals that live in the water, belonging to the stony corals and six-tentacled coral subclass, one of the orders, and are constructed very simply, without a central information processing organ, that is, they do not have the most basic brain foundation.

Although sea anemones look like flowers, they are actually predatory animals. Their dozens of tentacles all have a special cell that can release toxins.

Sea anemones are invertebrates, belonging to the phylum Cnidaria, class Anthozoa, and are single-celled animals with two germ layers. They have no exoskeleton and live entirely in the ocean. In warm seas, individuals are larger, with a cylindrical shape, with a slightly enlarged base (pedal disc), which secretes mucus. Because of mucus and muscle, it can be fixed to shallow rocks, wooden piles or shells, crabs, some species once fixed, will not move, and some species can move slightly on them. The upper end is a flattened mouth disc, with one long slit mouth in the center, generally with one narrow depression on either side of the mouth, called mouth groove, the mouth groove wall cells have cilia, when cilia move, can cause fresh water containing micro-organisms to enter along the mouth groove, not only can obtain food, also can conduct gas exchange, containing metabolic waste water, again through the mouth and the mouth center flow out.

tentacles have multiple rows, according to the six-fold rule, and can add up to 200 or more. The tentacles in the water constantly sway, like petals swaying in the wind. The tentacles generally lack activity, all their energy is concentrated on transmitting food to the central digestive system in order to fully meet their survival needs. Sea anemones have a very limited nervous system ability, but also have strong contraction and extension capabilities, with a developed pedal base and wall muscles to shrink or expand the column. When encountering danger, it will shrink its body, empty the tentacles, and retract all the tentacles into its body.
