Themistidae
''Themiste'' is a genus of peanut worms. It is the only genus in the family Themistidae. Members of this family are filter feeders, and have their feeding tentacles arranged in an elaborate crown-like structure. This is in contrast to other sipunculans which are deposit feeders. Species The genus contains the following species: * '' Themiste alutacea'' (Grube & Ørsted, 1858) * '' Themiste blanda'' (Selenka and de Man, 1883) * '' Themiste cymodoceae'' (Edmonds, 1956) * '' Themiste dehamata'' (Kesteven, 1903) * '' Themiste dyscrita'' (Fisher, 1952) * '' Themiste hennahi'' (Gray, 1828) * '' Themiste lageniformis'' (Baird, 1868) * '' Themiste minor'' (Ikeda, 1904) * ''Themiste pyroides ''Themiste pyroides'' is a species of unsegmented benthic marine worm in the phylum Sipuncula, the peanut worms.

Sipunculans
The Sipuncula or Sipunculida (common names sipunculid worms or peanut worms) is a class containing about 162 species of unsegmented marine annelid worms. The name ''Sipuncula'' is from the genus name ''Sipunculus'', and comes from the Latin ''siphunculus'' meaning a "small tube". Sipuncula was once considered a phylum, but was demoted to a class of Annelida, based on recent molecular work. Sipunculans vary in size but most species are under in length. The body is divided into an unsegmented, bulbous trunk and a narrower, anterior section, called the "introvert", which can be retracted into the trunk. The mouth is at the tip of the introvert and is surrounded in most groups by a ring of short tentacles. With no hard parts, the body is flexible and mobile. Although found in a range of habitats throughout the world's oceans, the majority of species live in shallow water habitats, burrowing under the surface of sandy and muddy substrates. Others live under stones, in rock crevic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Themiste Pyroides
''Themiste pyroides'' is a species of unsegmented benthic marine worm in the phylum Sipuncula, the peanut worms. It occurs in the intertidal zone and shallow water in the western Atlantic Ocean and the northeastern Pacific Ocean. It lives in crevices and under rocks, extending its "crown" of branching tentacles into the surrounding water to feed. Description ''Themiste pyroides'' is a large peanut worm. It has a cylindrical or spindle-shaped body and an extensible introvert at the tip of which is an elaborate "crown" of branching tentacles. The cuticle is covered by tiny papillae but seems smooth. The introvert is longer than the body and is fully retractable into the body. The crown consists of six dichotomously branching tentacles surrounding the mouth, the branches bearing pinnules, used by the worm for filter feeding (most sipunculids are deposit feeders). The body is yellowish-brown to dark brown, the collar (region of the introvert just below the crown) is smooth and blotc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Themiste Hennahi
''Themiste hennahi'' is a species of unsegmented benthic marine worm in the phylum Sipuncula, the peanut worms. It is native to shallow waters on the Pacific coast of North and South America. This worm was first described in 1828 by the British zoologist John Edward Gray as ''Themiste hennahi'', the type specimen having been collected by the Rev. W. Hennah, with the type locality being Peru. Description The body of this worm is cylindrical. The introvert (the retractable anterior part of the worm) is tipped by a crown-like structure of six branching tentacles which surround the mouth. The collar (immediately behind the tentacles) is not reddish-purple as it is in '' Themiste dyscrita'', and the introvert is devoid of spines. Distribution and habitat ''Themiste hennahi'' is native to the tropical and subtropical eastern Pacific Ocean, its range including the western coast of the United States, and the coasts of Peru and Chile. It burrows into sandy, gravelly, silty and muddy sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Anders Sandøe Ørsted (botanist)
Anders Sandøe Ørsted, also written as ''Anders Sandoe Oersted'' or ''Anders Sandö Örsted'' (21 June 1816 – 3 September 1872) was a Danish botanist, mycologist, zoologist and marine biologist. He was the nephew of physicist Hans Christian Ørsted and of politician Anders Sandøe Ørsted. Career In his early career, he published on Danish and Arctic nematodes and on the zonation of marine algae in Øresund. Between 1845 and 1848, he travelled extensively in Central America and the Caribbean and published numerous papers on the flora, concentrating on the plant families Acanthaceae and Fagaceae. One of his better known publications i''L'Amérique Centrale'' He was appointed professor of botany at the University of Copenhagen in 1851, a post he held until 1862. He was succeeded by Ferdinand Didrichsen. His studies of what has since been known as juniper-pear rust showed that this fungus annually switches between two hosts; ''Juniperus sabina'' is the primary ( telial) host a ...
