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 ...
Urticina piscivora, common names fish-eating anemone and fish-eating urticina, [2] is a northeast Pacific species of sea anemone in the family Actiniidae. [1] Description
It has been observed as a beneficial predator of Aiptasia and Majano sea anemones. They will eliminate this nuisance pest within a two- to six-week period depending on the anemone population and size of the tank; however, they will eagerly feed on any soft corals and may cause more harm than good to the decoration.
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.
The individual species are generally highly host specific. The sea anemone protects the anemonefish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles, and functions as a safe nest site. In return, the anemonefish defends the anemone from its predators and parasites.
Clark's anemonefish is the least host specific anemonefish, living in association with all ten species of sea anemones that host anemonefish: Cryptodendrum adhaesivum; Entacmaea quadricolor Bubble-tip anemone; Heteractis aurora beaded sea anemone; Heteractis crispa Sebae anemone; Heteractis magnifica magnificent sea anemone; Heteractis malu ...
The relationship between anemonefish and their host sea anemones is not random and instead is highly nested in structure. [9] A. akindynos is a generalist, being hosted by the following 6 out of the 10 host anemones: [4] [2] [9] Entacmaea quadricolor Bubble-tip anemone; Heteractis aurora beaded sea anemone; Heteractis crispa Sebae anemone
Intruding anemones are not normally killed but usually retire to a safer place. [2] Actinia bermudensis is an omnivore. The main items of prey are gastropods, isopods and small bivalves. Other food items may include other marine invertebrates and algae. [3] Many sea anemones form a symbiotic relationship with zooxanthellae.
