Stomphia Coccinea
''Stomphia coccinea'' is a small reddish, orange or brownish sea anemone in the family Actinostolidae from the North Atlantic, North Pacific and Arctic Ocean. It can swim away when necessary in order to escape a predator. Morphology The specific name ‘coccinea’ means ‘scarlet’ and refers to the anemone's distinctive often reddish and orange-striped coloration both on the column and on its up to 80 tentacles. The anemone can grow to a size of 6 cm in diameter, but the anemone has a very flat appearance when retracted. Ecology This species attaches itself to rocks and shells, with the most common substrate in northern Europe being the shell of the horse mussel ''Modiolus modiolus'', where, as a suspension feeder it consumes planktonic material. When there is an attack from one of its predators, such as a starfish, or an individual of the nudibranch species ''Aeolidia papillosa ''Aeolidia papillosa'', known as the common grey sea slug, is a species of nudibranch in ...

Sea Anemone
Sea anemones are a group of predation, predatory marine invertebrates of the order (biology), 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 (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional n ...

Modiolus Modiolus
''Modiolus modiolus'', common name northern horsemussel (Scottish Gaelic: , Scots: ), is a species of marine bivalve mollusk in the family Mytilidae. Description ''Modiolus modiolus'' is a large mussel growing to 22 cm (9ins) long though 10 cm (4ins) is a more typical size. The shell is purplish or dark blue and robust, with horny protuberances when young. The two valves are roughly triangular or bluntly oblong with rounded umbones near the anterior end. The annual growth lines are clear and there is a fine sculpturing of concentric grooves and ridges. The interior of the shell is white with a broad pallial line, large anterior adductor muscle scar and smaller posterior adductor muscle scar. The body is deep orange and the mantle is unfrilled. The shell is firmly attached to the substrate by byssus threads.

Nudibranch
Nudibranchs () are a group of soft-bodied marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", or "sea rabbit". Currently, about 3,000 valid species of nudibranchs are known.Ocean Portal (2017)A Collage of Nudibranch Colors Smithsonian National Museum of Natural History. Retrieved 17 April 2018. The word "nudibranch" comes from the Latin "naked" and the Ancient Greek () "gills". Nudibranchs are often casually called sea slugs, as they are a family of opistobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic ''Sacoglossa'' and the colourful Aglajidae, are often confused with nudibranchs. Distribut ...

Aeolidia Papillosa
''Aeolidia papillosa'', known as the common grey sea slug, is a species of nudibranch in the family Aeolidiidae.Gofas, S''Aeolidia papillosa''.In: MolluscaBase (2017). Accessed through: World Register of Marine Species (WoRMS), 26 July 2017. Distribution This nudibranch species thrives in cold-temperate waters in the Northern Hemisphere on the Atlantic coast of The British Isles and Northern Europe, the Atlantic coast of North America, and the north Pacific Coast of North America. This species has recently been shown to have a more restricted distribution than previously thought, with animals from California, France and Chile being three other species. Description ''Aeolidia papillosa'' can be easily identified by its large number of cylindrical cerata covering its body except for a triangular area that extends from the rhinophores to the mid dorsum. The color is variable, usually with speckled darker markings in the head and back regions. To distinguish from different Aeo ...

Cnidarians Of The Atlantic Ocean
Cnidaria () is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and Scyph ...

Animals Described In 1776
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...
