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 ...
Sea anemones (/ ə ˈ n ɛ m. ə. n i / ə-NEM-ə-nee) are a group of predatory marine invertebrates constituting 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.
When these anemones are growing alongside each other they appear to know whether or not they are closely related. If they are, they will tolerate each other's close presence, while if they are unrelated, they will attack each other. [5] The waratah anemone can also reproduce sexually with planktonic larvae settling far away from the parent ...
The nematocysts of the anemone can have dangerous effects, including the rupturing of human blood cells. The deeplet sea anemone was observed to have a symbiotic relationship with shrimp , as they cluster around its base in both temperate and Northwest Atlantic waters.
Pacific sea nettles, Chrysaora fuscescens. Cnidaria (/ n ɪ ˈ d ɛər i ə, n aɪ-/ nih-DAIR-ee-ə, NY-) [4] is a phylum under kingdom Animalia containing over 11,000 species [5] of aquatic invertebrates found both in fresh water and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites.
The anemones maintain the balance of the deep ocean by preying on small marine animals. Without the anemone, these smaller creatures could become abundant and overwhelm the resources of the ecosystem.

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.
