Acricoactis is a genus of sea anemones of the family Acricoactinidae. It currently includes only one species.
The following species are recognized: [2]
Venom is a type of poison, especially one secreted by an animal. Venom has evolved in a wide variety of animals, both predators and prey, and both vertebrates and invertebrates.
Anemone is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are commonly called windflowers. They are native to the temperate and subtropical regions of all continents except Australia, New Zealand and Antarctica. The genus is closely related to several other genera including Anemonoides, Anemonastrum, Hepatica, and Pulsatilla. Some botanists include these genera within Anemone.
Clownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized: one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild, they all form symbiotic mutualisms with sea anemones. Depending on species, anemonefish are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. The largest can reach a length of 17 cm, while the smallest barely achieve 7–8 cm.
Stichodactylidae is a family of sea anemones that contains the genera Stichodactyla and Heteractis. 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. 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 failure. In contrast, the venom of Heteractis has shown potential in treatment of lung cancer.
The aggregating anemone, or clonal anemone, is the most abundant species of sea anemone found on rocky, tide swept shores along the Pacific coast of North America. This cnidarian hosts endosymbiotic algae called zooxanthellae that contribute substantially to primary productivity in the intertidal zone. The aggregating anemone has become a model organism for the study of temperate cnidarian-algal symbioses.
Tube-dwelling anemones or ceriantharians look very similar to sea anemones but belong to an entirely different subclass of anthozoans. They are solitary, living buried in soft sediments. Tube anemones live inside and can withdraw into tubes, which are composed of a fibrous material made from secreted mucus and threads of nematocyst-like organelles known as ptychocysts. Within the tubes of these ceriantharians, more than one polyp is present, which is an exceptional trait because species that create tube systems usually contain only one polyp per tube. Ceriantharians were formerly classified in the taxon Ceriantipatharia along with the black corals but have since been moved to their own subclass, Ceriantharia.
Anemonastrum narcissiflorum, the narcissus anemone or narcissus-flowered anemone, is a herbaceous perennial in the genus Anemonastrum and the buttercup family. Basionym: Anemone narcissiflora Hook. & Arn.
The Alaska pollock or walleye pollock is a marine fish species of the cod genus Gadus and family Gadidae. It is a semi-pelagic schooling fish widely distributed in the North Pacific, with largest concentrations found in the eastern Bering Sea.
Cribrinopsis fernaldi, also known as the crimson anemone, snakelock anemone, chevron-tentacle anemone and Fernald brooding anemone, is a sea anemone native to the Pacific Ocean off northwestern North America.
Lybia is a genus of small crabs in the family Xanthidae. Their common names include boxer crabs, boxing crabs and pom-pom crabs. They are notable for their mutualism with sea anemones, which they hold in their claws for defense. In return, the anemones get carried around which may enable them to capture more food particles with their tentacles. Boxer crabs use at least three species of anemones, including Bundeopsis spp. and Triactis producta. The bonding with the anemone is not needed for survival, however, and boxer crabs have frequently been known to live without them, sometimes substituting other organisms such as sponges and corals for the sea anemones.
Sea anemones are the marine, predatory animals of the order Actiniaria. They are named after the anemone, a terrestrial flowering plant, because of the colourful appearance of many. 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.
Dendronotus iris is a species of sea slug, a dendronotid nudibranch, a shell-less marine gastropod mollusc in the family Dendronotidae.
Condylactis gigantea is a tropical species of ball anemone that is found in shallow reefs and other shallow inshore areas in the Caribbean Sea – more specifically the West Indies – and the western Atlantic Ocean including southern Florida through the Florida Keys. It is also commonly known as: giant Caribbean sea anemone, giant golden anemone, condylactis anemone, Haitian anemone, pink-tipped anemone, purple-tipped anemone, and Florida condy. This species can easily be seen growing in lagoons or in inner reefs as either individuals or loose groups, but never as colonies. They are often used as a model organism along with others in their genus for facultative symbiosis with monocellular algae.
Corallimorphus is a genus of colonial anthozoans similar in appearance to sea anemones and in body format to scleractinian stony corals. These animals are cnidarians in the family Corallimorphidae. Members of the genus live off the Pacific coast of the US.
Epiactis is a genus of sea anemones in the family Actiniidae. There are about nineteen recognised species and the type species is Epiactis prolifera.
Metridium farcimen is a species of sea anemone in the family Metridiidae. It is commonly known as the giant plumose anemone or white-plumed anemone. It is found in the eastern Pacific Ocean from Alaska down to Catalina Island, California.
Triactis is a genus of sea anemone in the family Aliciidae. It is monotypic, having only one species – Triactis producta. This is found in shallow waters in the Indo-Pacific where it lives on the seabed, rocks and corals. It derives much of its energy needs from the symbiotic algae it contains. It also forms a mutualistic relationship with small Lybia crabs.
Heteractis aurora is a species of sea anemone in the family Stichodactylidae.
Dofleinia armata, commonly known as the striped anemone or armed anemone, is a species of sea anemone in the family Actiniidae. It is the only species in the genus Dofleinia.
Acricoactinidae is a family of sea anemones. It currently includes only one species.
