Edwardsia timida, also known as the timid burrowing anemone, is a species of sea anemone in the family Edwardsiidae. [2] [3] [4]
This species of sea anemone has a maximum diameter of 5 mm (0.20 in) and maximum length of 7 cm (2.8 in); [5] it is similar to Edwardsia claparedii but even more elongate, with a translucent pale orange colour. It has 16–32 tentacles arranged in 3 cycles, with 4 larger tentacles in the primary cycle. [6] Its column is slender, without tubercles. It has cinclides (pores in the body wall for release of water and cnidocytes). [7] [8]
Edwardsia timida is found in the Irish Sea and English Channel. [9] It is one of 943 species listed by Natural England in 2014 as species of principal importance for the conservation of biodiversity in England. [10]
Edwardsia timida burrows in sand or gravel from lower shore to shallow sublittoral. [11] [12]
Calliactis is a genus of sea anemones. Species in this genus are mutually symbiotic with hermit crabs. The anemone gets a place to live and discarded scraps of the crab's food in exchange for its help in defending the crab.
The sebae anemone, also known as leathery sea anemone, long tentacle anemone, or purple tip anemone, is a species of sea anemone belonging to the family Stichodactylidae and native to the Indo-Pacific area.
Hexacorallia is a class of Anthozoa comprising approximately 4,300 species of aquatic organisms formed of polyps, generally with 6-fold symmetry. It includes all of the stony corals, most of which are colonial and reef-forming, as well as all sea anemones, and zoanthids, arranged within five extant orders. The hexacorallia are distinguished from another class of Anthozoa, Octocorallia, in having six or fewer axes of symmetry in their body structure; the tentacles are simple and unbranched and normally number more than eight. These organisms are formed of individual soft polyps which in some species live in colonies and can secrete a calcite skeleton. As with all Cnidarians, these organisms have a complex life cycle including a motile planktonic phase and a later characteristic sessile phase. Hexacorallia also include the significant extinct order of rugose corals.
Ivell's sea anemone is a species of sea anemone in the family Edwardsiidae. It is endemic to a single location, Widewater Lagoon in West Sussex, England, where it was first discovered by Richard Ivell. It has been listed as Data Deficient by the IUCN since 1996.
Edwardsia is a genus of sea anemones, the type of the family Edwardsiidae. They have eight mesenteries and live in tubes in the sand. The name, in New Latin, commemorates the French zoologist Henri Milne-Edwards.
The snakelocks anemone is a sea anemone found in the eastern Atlantic Ocean and the Mediterranean Sea. The latter population is however sometimes considered a separate species, the Mediterranean snakelocks anemone.
The Fungiidae are a family of Cnidaria, commonly known as mushroom corals or plate corals. The family contains thirteen extant genera. They range from solitary corals to colonial species. Some genera such as Cycloseris and Fungia are solitary organisms, Polyphyllia consists of a single organism with multiple mouths, and Ctenactis and Herpolitha might be considered as solitary organisms with multiple mouths or a colony of individuals, each with its separate mouth.
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.
Phymanthus crucifer, commonly known as rock flower anemone, flower anemone, red beaded anemone or the beaded anemone, is a species of sea anemone in the family Phymanthidae. It has been described as "closely similar" to Heteractis aurora in several ways, commonly exhibiting "tentacles with swollen cross-bars" bearing large clusters of stinging nematocysts. However, P. crucifer may also be found with smooth tentacles, sometimes in the immediate vicinity of a swollen-crossbarred specimen.
Haliclystus auricula is a stalked jellyfish found in the Northern hemisphere. It is the type species for its genus.
Diploria is a monotypic genus of massive reef building stony corals in the family Mussidae. It is represented by a single species, Diploria labyrinthiformis, commonly known as grooved brain coral and is found in the western Atlantic Ocean and Caribbean Sea. It has a familiar, maze-like appearance.
Actinostephanus haeckeli, also known as the snake sea anemone or Haeckles sea anemone, is a species of sea anemone in the family Actinodendridae.
Edwardsiidae is a family of sea anemones. Edwardsiids have long thin bodies and live buried in sediments or in holes or crevices in rock.
Leptopsammia pruvoti, the sunset cup coral, is a solitary stony coral in the family Dendrophylliidae. It is an azooxanthellate species, meaning its tissues do not contain the symbiotic unicellular algae (zooxanthellae) of the genus Symbiodinium, as do most corals. It is native to the Mediterranean Sea. The species was described by Henri de Lacaze-Duthiers in 1897 and named to honor the French marine biologist Georges Pruvot.
Edwardsia claparedii is a species of sea anemone in the family Edwardsiidae.
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.
The spotted ray or spotted skate is a species of skate in the family Rajidae.
The shortfin spiny eel, also called Bonaparte's spiny eel, is a member of the family Notacanthidae, the deep-sea spiny eels, which are not true eels (Anguilliformes).
Stomias boa ferox is a subspecies of deep-sea fish in the family Stomiidae.
