Most species burrow in the substrate but some live in the empty shells of gastropods. It is an order of the class Sipuncula (previously considered a phylum), and contains the following families: * Golfingiidae * Phascolionidae ''Phascolionidae'' is a family of peanut worms The Sipuncula or Sipunculida (common names sipunculid worms or peanut worms) is a class containing about 162 species of unsegmented marine annelid worms.

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.

Peanut Worms
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 crev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Substrate (biology)
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae. Inert substrates are used as growing support materials in the hydroponic cultivation of plants. In biology substrates are often activated by the nanoscopic process of substrate presentation. In agriculture and horticulture * Cellulose substrate * Expanded clay aggregate (LECA) * Rock wool * Potting soil * Soil In animal biotechnology Requirements for animal cell and tissue culture Requirements for animal cell and tissue culture are the same as described for plant cell, tissue and organ culture (In Vitro Culture Techniques: The Biotechnological Principles). Desirable requirements are (i) air conditioning of a room, (ii) hot room with temperature recorder, (iii) microscope r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropoda
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
