Sea anemone feeding at night #shorts - Get an up-close look at a sea anemone (or polyp) in action as it feeds on small sea creatures like shrimps and worms in this night dive footage filmed at Panagsama Beach, Moalboal, Cebu, Philippines. A highly recommended location for night diving, this video offers a unique perspective on the feeding behavior of sea anemones.

About the feeding behavior of sea anemones:

Sea anemones are carnivorous animals that feed on a variety of small aquatic organisms such as plankton, crustaceans, and fish. They capture their prey using their long, venomous tentacles, which are lined with specialized cells called cnidocytes. These cells contain stinging structures called nematocysts, which are used to paralyze and capture prey. Once the prey is captured, it is brought to the anemone's oral disk and then ingested. Some species of sea anemones also engage in symbiotic relationships with certain species of fish, such as clownfish, in which the anemone provides protection for the fish and the fish provides food for the anemone.

Sea anemones on Wikipedia: [ Ссылка ]
Anemones are a group of predatory marine invertebrates of the order Actiniaria. Because of their colourful appearance, they are named after the Anemone, a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and Hydra. Unlike jellyfish, sea anemones do not have a medusa stage in their life cycle.

A typical sea anemone is a single polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional nourishment comes from a symbiotic relationship with single-celled dinoflagellates, with zooxanthellae, or with green algae, zoochlorellae, that live within the cells. Some species of sea anemone live in association with clownfish, hermit crabs, small fish, or other animals to their mutual benefit.

Sea anemones breed by liberating sperm and eggs through the mouth into the sea. The resulting fertilized eggs develop into planula larvae which, after being planktonic for a while, settle on the seabed and develop directly into juvenile polyps. Sea anemones also breed asexually, by breaking in half or into smaller pieces which regenerate into polyps. Sea anemones are sometimes kept in reef aquariums; the global trade in marine ornamentals for this purpose is expanding and threatens sea anemone populations in some localities, as the trade depends on collection from the wild.
