Located along the eastern coast of the U.S., with a few introduced populations scattered along the western U.S. coast and the southeast coast of Britain, this sea anemone is a member of the sea ...
The sea anemone benefits from the products of the algae's photosynthesis, namely oxygen and food in the form of glycerol, glucose and alanine; the algae in turn are assured a reliable exposure to sunlight and protection from micro-feeders, which the sea anemones actively maintain. The algae also benefit by being protected by the sea anemone's ...
Aiptasia is a widely distributed genus of temperate and tropical sea anemones of benthic lifestyle typically found living on mangrove roots and hard substrates. These anemones, as well as many other cnidarian species, often contain symbiotic dinoflagellate unicellular algae of the genus Symbiodinium living inside nutritive cells.
These sea anemones exclusively reside within the shallow waters of the tropical Indo-Pacific area and are in the main family of sea anemones that hosts several varieties of clownfishes. [1] Most sea anemone species are harmless to humans, but at least some Stichodactyla are highly venomous and their sting may cause anaphylactic shock and organ ...
There are thousands of different species of sea anemones in the ocean with some living as far deep as 32,000 feet. ... We also do not yet know the detrimental effects that deep-sea mining might ...
The giant Caribbean sea anemone is a macrophagous carnivore and feeds upon fish, mussels, shrimp, zooplankton, and sea worms. It will not, however, go near any natural predators, such as red leg hermits, the grey sea slug, or the tompot blenny. The anemone's nematocysts help it to capture food as well as defend against predators.
A number of sea anemone species are commensal with other organisms. Certain crabs and hermit crabs seek out sea anemones and place them on their shells for protection, and fish, shrimps and crabs live among the anemone's tentacles, gaining protection by being in close proximity to the stinging cells.
When a predator approaches the anemone, their reaction is to withdraw their tentacles and oral disc. These are the preferred attack sites for predators, because the concentration of anthopleurin is the lowest in these sites. The body region of the sea-anemone that is exposed to the predator contains the highest concentration of anthopleurin.
