Meioglossus
''Meioglossus psammophilus'' is a species of acorn worm in the family Harrimaniidae, the only known species of the genus ''Meigolossus''. It inhabits the Western Caribbean and Bermuda. The name of the species derives from two Greek words; ''psammon'' and ''philos'' which in translation means ''friend of the sands'' in reference to adult stage of species' lifestyle. The length of the species is . It is able to reproduce asexually through paratomy Paratomy is a form of asexual reproduction in animals where the organism splits in a plane perpendicular to the antero-posterior axis and the split is preceded by the "pregeneration" of the anterior structures in the posterior portion.

Acorn Worm
The acorn worms or Enteropneusta are a Hemichordata, hemichordate class of invertebrates consisting of one order of the same name. The closest non-hemichordate relatives of the Enteropneusta are the echinoderms. There are 111 known species of acorn worm in the world, the main species for research being ''Saccoglossus kowalevskii''. Two families—Harrimaniidae and Ptychoderidae—separated at least 370 million years ago. Until recently, it was thought that all species Fauna (animals)#Infauna, lived in the sediment on the seabed, subsisting as deposit feeders or suspension feeders. However, the early 21st century has seen the description of a new family, the Torquaratoridae, evidently limited to the deep sea, in which most of the species crawl on the surface of the ocean bottom and alternatively rise into the water column, evidently to drift to new foraging sites. It is assumed that the ancestors of acorn worms used to live in tubes like their relatives Pterobranchia, but that they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harrimaniidae
Harrimaniidae is a basal family of acorn worms. A taxonomic revision was undertaken in 2010, and a number of new genera and species found in the Eastern Pacific were described. In this family the development is direct without tornaria larva, and circular muscle fibers in their trunk is missing. There is some indication that Stereobalanus may be a separate basal acorn worm lineage, sister to all remaining acorn worms. Species The following genera and species are listed in the World Register of Marine Species: .

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Hemichordate
Hemichordata is a phylum which consists of triploblastic, enterocoelomate, and bilaterally symmetrical marine deuterostome animals, generally considered the sister group of the echinoderms. They appear in the Lower or Middle Cambrian and include two main classes: Enteropneusta (acorn worms), and Pterobranchia. A third class, Planctosphaeroidea, is known only from the larva of a single species, ''Planctosphaera pelagica''. The class Graptolithina, formerly considered extinct, is now placed within the pterobranchs, represented by a single living genus ''Rhabdopleura''. Acorn worms are solitary worm-shaped organisms. They generally live in burrows (the earliest secreted tubes) and are deposit feeders, but some species are pharyngeal filter feeders, while the family Torquaratoridae are free living detritivores. Many are well known for their production and accumulation of various halogenated phenols and pyrroles. Pterobranchs are filter-feeders, mostly colonial, living in a collageno ...

Worsaae
Jens Jacob Asmussen Worsaae (14 March 1821 – 15 August 1885) was a Danish archaeologist, historian and politician, who was the second director of the National Museum of Denmark (1865–1874). He played a key role in the foundation of scientific archaeology. Worsaae was the first to excavate and use stratigraphy to prove C. J. Thomsen's sequence of the Three-age system: Stone, Bronze, Iron. He was also a pioneer in the development of paleobotany through his excavation work in the peat bogs of Jutland. Worsaae served as Kultus Minister of Denmark (the cultural and education minister) for Christen Andreas Fonnesbech from 1874 to 1875. Early life and education Jens Jacob Asmussen Worsaae was born in Vejle, Denmark in 1821. He was the fifth of eleven children born into a wealthy, educated family. His father was a civil servant (a county treasurer) for the County of Vejle and also a member of the Royal Society of Northern Antiquities. Worsaae's archaeological interests began in 1832 ...

Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...
