Actinia striata is a species of sea anemone endemic to the Mediterranean Sea. [3]
Actinia striata is a solitary sea anemone. The cylindrical column can grow to a height and diameter of 3 cm (1.2 in) and the foot flares out to a diameter of 6 cm (2.4 in). The crown consists of six whorls of tentacles making 196 tentacles in all. The column is variable in colour, smooth and finely striated, reddish, dull green or brown, with darker streaks. The tentacles are reddish or greenish and the oral disc is plain red and somewhat transparent. The tentacles can be fully retracted, and then the sea anemone resembles a striped gelatinous mound. [3]
This species is endemic to the western Mediterranean Sea. Its range includes the Mediterranean coasts of Spain and France, Italy, Greece, Croatia and Morocco. [1] It occurs down to about 30 m (100 ft) and is found attached to rock in both well lit areas and among seaweed and under rocks. It can occur at greater depths than Actinia mediterranea or Actinia equina . [3]
Like other sea anemones, it is carnivorous, feeding on zooplankton which it catches with its tentacles, which thrust the prey into the mouth. It is a generally uncommon species. The sexes are separate and it is viviparous, with breeding probably taking place in summer. [3]
Actinia striata is found in very shallow water in the Mediterranean Sea and nowhere else. The International Union for Conservation of Nature has assessed its conservation status as being "data deficient" because too little is known about its distribution or population size, and its status. Because of the shallowness of the water in which it lives, it is likely to be affected by the discharge of untreated sewage and deteriorating water quality. However, it is present in several marine protected areas. More research needs to be undertaken to identify the threats that it faces. [1]
The beadlet anemone is a common sea anemone found on rocky shores around all coasts of the British Isles. Its range extends to the rest of Western Europe and the Mediterranean Sea, and along the Atlantic coast of Africa as far south as South Africa.
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.
Actinia tenebrosa, commonly named 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.
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.
Actinia cari is a species of sea anemone in the family Actiniidae. It is native to the Mediterranean Sea where it is an uncommon species.
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.
Phlyctenanthus australis, commonly known as red anemone and southern anemone, is a species of sea anemone in the family Actiniidae. It grows to a maximum size of 10 cm in diameter. The column is red-brown in colour with blue vesicles covering it. The tentacles are reddish-brown and short, and number up to around 100. This species is found in south Australia, New South Wales, down to Tasmania. This species lives on exposed reefs at depths of between 1 and 35 metres.
Actinia mediterranea is a common sea anemone found on rocky shores all along its range in the Mediterranean Sea, Portuguese shores and the coast of north western Africa. Because of its strong resemblance with Actinia equina, they are often confused and share certain common names as Beadlet anemone.
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.
Astroides is a genus of stony cup corals in the family Dendrophylliidae. It is monotypic and the only species is Astroides calycularis, which is endemic to the western Mediterranean Sea. The species was first described in 1766 by the German naturalist Peter Simon Pallas.
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.
Cerianthus membranaceus, the cylinder anemone or coloured tube anemone, is a species of large, tube-dwelling anemone in the family Cerianthidae. It is native to the Mediterranean Sea and adjoining parts of 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.
Paranthus rapiformis, the onion anemone, is a species of sea anemone in the family Actinostolidae. It was first described by the French naturalist Charles Alexandre Lesueur in 1817 and is native to the northwestern Atlantic Ocean and the Gulf of Mexico.
Epiactis ritteri, the sandy anemone or Ritter's brooding anemone, is a species of sea anemone in the family Actiniidae. It is found in the Pacific Ocean on the western coast of North America in the shallow sub-littoral zone.
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.
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.
Isotealia antarctica, the salmon anemone, is a species of sea anemone in the family Actiniidae. It is found in the southern Atlantic and Pacific Oceans and the waters around Antarctica. It is a filter feeder and opportunistic predator.
