Heteractis magnifica, also known by the common names magnificent sea anemone or Ritteri anemone, is a species of sea anemone belonging to the Stichodactylidae family native to the Indo-Pacific area.
Stichodactyla is a genus of sea anemones, of the family Stichodactylidae. They are host anemones, which maintain a relationship mutualistic with other animals, in their case with crabs of the genus Mithraculus, shrimp of the genus Periclimenes , and with various species of clownfish, of the genus Amphiprion, establishing a relationship of coexistence. In this way, crabs and fish protect themselves from their predators between the stinging tentacles of the anemone, and the anemone benefits from the cleaning of its oral disc and tentacles as a result of the continuous movements of the animals.
The starburst anemone or sunburst anemone is a species of sea anemone in the family Actiniidae. The sunburst anemone was formerly considered the solitary form of the common aggregating anemone, but was identified as a separate species in 2000.
Urticina crassicornis, commonly known as the mottled anemone, the painted anemone or the Christmas anemone, is a large and common intertidal and subtidal species of 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.
Members of the genus Metridium, also known as plumose anemones, are sea anemones found mostly in the cooler waters of the northern Pacific and Atlantic oceans. They are characterized by their numerous threadlike tentacles extending from atop a smooth cylindrical column, and can vary from a few centimeters in height up to one meter or more. In larger specimens, the oral disk becomes densely curved and frilly.
Sea anemones 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. 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.
Diadumene lineata, the orange-striped green sea anemone, has several morphotypes which have been described multiple times.
Nemanthus annamensis, commonly known as the gorgonian wrapper, is a species of sea anemone found in central Indo-Pacific waters.
Actinia tenebrosa, commonly known as the waratah anemone, is the most common species of sea anemone found in the waters of eastern Australia and New Zealand. It is found relatively high on the seashore, in rock pools, and various cracks and shaded surfaces such as under rock overhangs in the intertidal zone.
Epiactis prolifera, the brooding, proliferating or small green anemone, is a species of marine invertebrate in the family Actiniidae. It is found in the north-eastern Pacific. It has a feature rare among animals in that all individuals start life as females but develop testes later in their lives to become hermaphrodites.
Metridium senile, the plumose, fluffy, 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.
Urticina eques is a species of sea anemone in the family Actiniidae. It is commonly known as the white-spotted rose anemone or strawberry anemone.
Actinodendron arboreum, commonly known as tree anemone or hell's fire anemone, is a species of sea anemone in the family Actinodendronidae. It is native to the Indo-Pacific where it grows at depths of down to 28 metres (92 ft). Most sea anemone species are harmless to humans, but A. arboreum is highly venomous and its sting can cause severe skin ulcers.
Phyllodiscus is a monotypic genus of sea anemones in the family Aliciidae. The only species is Phyllodiscus semoni, commonly known as the night anemone, which is native to shallow seas in the central Indo-West Pacific, such as Indonesia, the Philippines and southern Japan. It is venomous and can cause a painful, long-lasting sting to humans. It is called unbachi-isoginchaku in Japanese which translates as "wasp-sea anemone".
Anthopleura stellula is a species of sea anemone in the family Actiniidae. It was first described in 1834 by Wilhelm Hemprich and Christian Gottfried Ehrenberg as Actinia (Isacmaea) stellula. 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.
Gonactinia is a monotypic genus of sea anemones, and G. prolifera is the only species in the genus. It is sometimes called the storey anemone and is found on either side of the northern Atlantic Ocean.
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.
Epiactis lisbethae, commonly known as Lisbeth's brooding anemone, is a species of sea anemone in the family Actiniidae. It is similar in appearance to the common brooding anemone, and like it is native to shallow waters on the western coast of North America.
Epiactis fernaldi, commonly known as the Fernald brooding anemone, is a species of sea anemone in the family Actiniidae. It is native to shallow waters around the San Juan Islands off the western coast of North America.
Metridium dianthus is a species of sea anemone in the family Metridiidae. It is found in the northern Atlantic Ocean and in the northeast Pacific Ocean. There is also a record from South Africa, possible resulting from an introduction.
