Aulactinia veratra, the green snakelock anemone, is a species of sea anemone in the family Actiniidae. It is native to the southeastern Indian Ocean and the southwestern Pacific Ocean.
The green snakelock anemone averages about 20 mm (0.8 in) in height, but individuals in some areas have reached 60 mm (2.4 in) when fully extended. The broad column has rows of verrucae (wart-like outgrowths) on its surface to which coarse grains of sand and fragments of shell adhere. The oral disc has a central mouth surrounded by a whorl of long, tapering tentacles with blunt tips, varying in number from 24 to 124. When expanded, both the column and tentacles of this anemone are usually green, but brown or red individuals sometimes occur. When retracted, with the oral disc and tentacles tucked inside the body cavity, green individuals may appear black. [2]
The green snakelock anemone is found in shallow seas around the west, south, and east coasts of Australia, Tasmania and both islands of New Zealand. It is found in the intertidal zone in rock pools, under overhangs, between boulders, and in crevices. The base is firmly attached to a rocky substrate even when the anemone is in a rock pool and appears to be immersed in sand. It is often found growing close to the sand anemone. [2]
The dahlia anemone is a sea anemone found in the north Atlantic Ocean, the North Sea and the Baltic Sea. Its colour is variable, from deep red to brown or purplish, with green spots and darker tentacles. Dahlia anemones live attached to rock on the seabed from the lower tidal limit down to a depth of 100 m and also attached to other organisms. Their diet comprises small fish and crustaceans, which they immobilize by firing groups of stinging cells (cnidae) into them. Dahlia anemones are closely related to mottled anemones, and both species are usually referred to as northern red anemones.
Anemonia sulcata, or Mediterranean snakelocks sea anemone, is a species of sea anemone in the family Actiniidae from the Mediterranean Sea. Whether A. sulcata should be recognized as a synonym of A. viridis remains a matter of dispute.
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.
Urticina crassicornis, commonly known as the mottled anemone, the painted anemone or the Christmas anemone, is a large and common intertidal and subtidal sea anemone. Its habitat includes a large portion of the coastal areas of the northern hemisphere, mainly polar regions, and it lives a solitary life for up to 80 years. Mottled anemones are similar to Dahlia anemones and both are commonly referred to as northern red 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.
Sagartia troglodytes is a species of sea anemone in the family Sagartiidae, also known as the mud sagartia or the cave-dwelling anemone.
Metridium senile, or frilled anemone, is a species of sea anemone in the family Metridiidae. As a member of the genus Metridium, it is a type of plumose anemone and is found in the seas off north-western Europe and both the east and west coasts of North America.
Anthothoe albocincta, or white-striped anemone, is a species of sea anemone in the family Sagartiidae. It is native to the coasts of Australia and New Zealand.
Oulactis muscosa, also known as the sand anemone and speckled anemone, is a species of sea anemone in the family Actiniidae.
Heteractis malu, also known as the malu anemone, delicate sea anemone or white sand anemone, is a species of sea anemone in the family Stichodactylidae.
Condylactis aurantiaca, commonly known as the golden anemone, is a species of sea anemone in the family Actiniidae. This species always remains largely buried in sand or sediment, attached to the substrate, with only the oral disc and tentacles visible.
Aiptasia diaphana, commonly known as the yellow aiptasia or glasrose, is a species of sea anemone native to shallow waters in the temperate eastern Atlantic Ocean and the Mediterranean Sea. It has been introduced into the Red Sea.
Anthopleura thallia, commonly known as the glaucous pimplet, is a species of sea anemone in the family Actiniidae. It is found in shallow water in the northeastern Atlantic Ocean and the Mediterranean Sea.
Diadumene cincta is a small and delicate, usually orange, sea anemone. It has a smooth slender column and up to 200 long tentacles, and normally grows to a length of up to 35 mm (1.4 in), with a base of 10 mm (0.4 in), but specimens twice this size have been recorded. Diadumene cincta is found in the northeastern Atlantic Ocean.
Actinothoe sphyrodeta, the sandalled anemone, is a small sea anemone in the family Sagartiidae. It is native to the northeastern Atlantic Ocean and is common on the north, west and south coasts of Britain. It is usually grey or whitish but may have an orange oral disc. The translucent white tentacles that grow around the edge of the oral disc can number up to 120.
Anthopleura stellula is a species of sea anemone in the family Actiniidae. It is found in the Indian Ocean and the Red Sea, and is unusual among sea anemones in that it can divide itself in two transversely.
Actinostola callosa is a species of sea anemones in the family Actinostolidae in the order Actiniaria. It is a deep sea species and occurs in both Pacific and Atlantic Oceans from the continental shelf to abyssal depths.
Metridium canum is a species of sea anemone in the family Metridiidae. It is found in the southwestern Pacific Ocean and the seas off New Zealand.
Corynactis viridis, the jewel anemone, is a brightly coloured anthozoan similar in body form to a sea anemone or a scleractinian coral polyp, but in the order Corallimorpharia. It is found in the northeastern Atlantic Ocean and the Mediterranean Sea and was first described by the Irish naturalist George Allman in 1846.
Mesacmaea mitchellii is a species of sea anemone in the family Haloclavidae. It is found in the northeastern Atlantic Ocean and the Mediterranean Sea where it burrows in soft sediment.
