Plumose Anemone
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.

Henri Marie Ducrotay De Blainville
Henri Marie Ducrotay de Blainville (; 12 September 1777 – 1 May 1850) was a French zoologist and anatomist. Life Blainville was born at Arques, near Dieppe. As a young man he went to Paris to study art, but ultimately devoted himself to natural history. He attracted the attention of Georges Cuvier, for whom he occasionally substituted as lecturer at the Collège de France and at the Athenaeum Club, London. In 1812 he was aided by Cuvier in acquiring the position of assistant professor of anatomy and zoology in the Faculty of Sciences at Paris. Eventually, relations between the two men soured, a situation that ended in open enmity. In 1819, Blainville was elected a member of the American Philosophical Society in Philadelphia. In 1825 he was admitted a member of the French Academy of Sciences; and in 1830 he was appointed to succeed Jean-Baptiste Lamarck in the chair of natural history at the museum. Two years later, on the death of Cuvier, he obtained the chair of comparative a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tentacle
In zoology, a tentacle is a flexible, mobile, and elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work mainly like muscular hydrostats. Most forms of tentacles are used for grasping and feeding. Many are sensory organs, variously receptive to touch, vision, or to the smell or taste of particular foods or threats. Examples of such tentacles are the eyestalks of various kinds of snails. Some kinds of tentacles have both sensory and manipulatory functions. A tentacle is similar to a cirrus, but a cirrus is an organ that usually lacks the tentacle's strength, size, flexibility, or sensitivity. A nautilus has cirri, but a squid has tentacles. Invertebrates Molluscs Many molluscs have tentacles of one form or another. The most familiar are those of the pulmonate land snails, which usually have two sets of tentacles on the head: when extended ...

Metridium Canum
''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. Description ''M. canum'' has a cylindrical column of about 10mm diameter, that is wider at the base than it is high when contracted. Cinclides (specialist pores) are present on the upper part of the column, and there are four or five whorls of crowded tentacles on the oral disc. Internally, there are forty-five pairs of mesenteries in four cycles radiating from the body wall. This sea anemone is grey, the tentacles sometimes having black tips. Distribution and habitat The species is native to the Southwest Pacific and the Kermadec Islands The Kermadec Islands ( mi, Rangitāhua) are a subtropical island arc in the South Pacific Ocean northeast of New Zealand's North Island, and a similar distance southwest of Tonga.

Metridium Dianthus
''Metridium dianthus'' is a species of sea anemone in the family Metridiidae. It is found in the northern Atlantic Ocean (including the coasts of the British Isles) and in the northeast Pacific Ocean. There is also a record from South Africa, possible resulting from an introduction. Description This is the largest sea anemone in the northeastern Atlantic; the smooth column can be in height with a pedal disc wider than this. This form is known as "dianthus" and on a large specimen, the oral disc may have a plume of several thousand tentacles some across, often forming several lobes. A smaller form, found most often in brackish water, is known as "pallidus" and may have two hundred tentacles and be across. Distribution and habitat ''Metridium dianthus'' is an adaptable, circumboreal species in the Northern Hemisphere. In the eastern Atlantic, its range extends from the Kola Peninsula in northern Russia to the Bay of Biscay, in the western Atlantic from the Arctic Circle to Dela ...

Metridium Farcimen
''Metridium farcimen'' is a species of sea anemone in the Family (biology), 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 Santa Catalina Island (California), Catalina Island, California. Taxonomy In 1990, Fautin et al. examined the validity of the name ''Metridium giganteum''. A further study in 2000 concluded that ''Actinia priapus''; Tilesius, 1809, ''Actinia farcimen''; Brandt, 1835, and ''Isometridium rickettsi''; Carlgren, 1949 were all synonym (taxonomy), synonyms of ''Metridium giganteum''. Of these, ''Actinia farcimen'' was the name first published. It is, however, a junior Homonym (biology), homonym so the valid name for the species is ''Metridium farcimen''; (Brandt, 1835). Description ''Metridium farcimen'' is a large sea anemone, occasionally reaching a height of one metre (39 in) when fully extended. More usually it is or less in height but is very va ...

Wilhelm Gottlieb Tilesius Von Tilenau
Wilhelm Gottlieb Tilesius von Tilenau (17 July 1769 – 17 May 1857) was a German naturalist and explorer, physician, draftsman and engraver. He was a member of the Order of St. Vladimir and of the Legion of Honour. Early life and education Wilhelm Gottlieb Tilesius was born in Mühlhausen (then part of the Holy Roman Empire) on 17 July 1769. His father was a merchant and actuary and his mother the daughter and sister of surgeons. It was his mother's brother who introduced the young Tilesius to the natural sciences and drawing. In 1790 Tilesius began studies of natural sciences and medicine at the University of Leipzig, and at the same time took drawing lessons from Adam Friedrich Oeser at the art academy in the Pleissenburg. He completed his master's degree of arts in 1795, graduated as a doctor of philosophy in 1797, and in 1801 as a doctor of medicine. In 1795-96 he traveled with the earl and scientist Johann Centurius Hoffmannsegg by ship to Portugal. On this trip he st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metridium Senile
''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. Description The base of ''Metridium senile'' is considerably wider than the column and is attached to rock or another substrate. The column is long, smooth and cylindrical, of a fleshy consistency with a slimy surface lubricated with mucus. There are no warts or suckers and the column is topped by a parapet and deep groove. The oral disc is broad and deeply lobed into several curving sections that overhang the column. The slender, pointed tentacles are very numerous in larger specimens though fewer and relatively longer in smaller ones. Those near the margin are crowded and short whereas further into the disc they are longer and more dispersed. The colour range of this sea anemone is large but for any one spec ...
