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] |

Medusa (biology)
Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary polyp phase before reaching sexual maturity. Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the "true jellyfish") are exclusively marine, but some hydrozoans with a similar appearance live in freshwater. Large, often colorful, jellyfish are common in coa ...

Philip Henry Gosse
Philip Henry Gosse FRS (; 6 April 1810 – 23 August 1888), known to his friends as Henry, was an English naturalist and populariser of natural science, an early improver of the seawater aquarium, and a painstaking innovator in the study of marine biology. Gosse created and stocked the first public aquarium at the London Zoo in 1853, and coined the term "aquarium" when he published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'', in 1854. His work was the catalyst for an aquarium craze in early Victorian England.Katherine C. Grier (2008) ''Pets in America: A History''. p. 53. University of North Carolina Press Gosse was also the author of '' Omphalos'', an attempt to reconcile the geological ages presupposed by Charles Lyell with the biblical account of creation. After his death, Gosse was portrayed as an overbearing father of uncompromising religious views in ''Father and Son'' (1907), a memoir written by his son, Edmund Gosse, a poet and critic ...
