Haloclavidae

	Haloclavidae Haloclavidae is a family of sea anemones. Members of the family are found worldwide and many live largely buried in soft substrates with only their oral disc and tentacles protruding. Characteristics Members of this family mostly have elongated columns which are often differentiated into different regions. The column is either smooth or has tubercles or suckers on its surface. The base is often rounded and used for digging but in some species it is flattened and adhesive to small objects. There is usually no sphincter but when one is present, it is endodermal. The tentacles are short and there are seldom more than 48, arranged cyclically. The mesenteries or internal tissue walls are few. There are no muscles attaching them to the basal disc but they do have strong retractor muscles. At least six pairs of the mesenteries are perfect, reaching from the base as far as the actinopharynx or throat of the anemone. There is a single, well defined siphonoglyph The siphonoglyph is a ciliat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Peachia Quinquecapitata ''Peachia quinquecapitata'', also known as the twelve-tentacled parasitic anemone, is a species of sea anemone in the family Haloclavidae. It is found in the Pacific Northwest. The larva is parasitic on certain species of Anthomedusae. Description ''Peachia quinquecapitata'' lives with its elongated column buried in the sand and its twelve tentacles fanned out on the surface. The oral disc is red and the translucent tentacles are banded with buff and brown in a chevron pattern. Like other members of the genus '' Peachia'', it has a "conchula", an enlargement on the lip by its mouth, which in this species is divided into five lobes. Distribution ''Peachia quinquecapitata'' is found in shallow seas in the Pacific Northwest of the United States including Puget Sound. Life cycle The life cycle of ''Peachia quinquecapitata'' was investigated in the laboratory. Spawning was induced by manipulating light levels. The eggs had a diameter of 120 µm and, after fertilisation, develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Addison Emery Verrill Addison Emery Verrill (February 9, 1839 – December 10, 1926) was an American invertebrate zoologist, museum curator and university professor. Life Verrill was born on February 9, 1839 in Greenwood, Maine, the son of George Washington Verrill and Lucy (Hillborn) Verrill. As a boy he showed an early interest in natural history, building collections of rocks and minerals, plants, shells, insects and other animals. When he moved with his family to Norway, Maine at age fourteen he attended secondary school at the Norway Liberal Institute. Verrill started college in 1859 at Harvard University and studied under Louis Agassiz. He graduated in 1862 with a B.A. He went on scientific collecting trips with Alpheus Hyatt and Nathaniel Shaler in the summer of 1860 to Trenton Point, Maine and Mount Desert Island and in the summer of 1861 to Anticosti Island and Labrador. In 1864 Verrill made reports on mining, or prospective mining, properties in New Hampshire, New York, and Pennsylvania. Tw ...
