picture info	Echiura The Echiura, or spoon worms, are a small group of ocean, marine animals. Once treated as a separate phylum, they are now considered to belong to Annelida. Annelids typically have their bodies divided into Segmentation (biology), segments, but echiurans have secondarily lost their segmentation. The majority of echiurans live in burrows in soft sediment in shallow water, but some live in rock crevices or under boulders, and there are also deep sea forms. More than 230 species have been described. Spoon worms are cylindrical, soft-bodied animals usually possessing a non-retractable proboscis which can be rolled into a scoop-shape to feed. In some species the proboscis is ribbon-like, longer than the trunk and may have a forked tip. Spoon worms vary in size from less than a centimetre in length to more than a metre. Most are deposit feeders, collecting detritus from the sea floor. Fossils of these worms are seldom found and the earliest known fossil specimen is from the Darriwilian, ...

	Echiuridae Echiuridae is a family of spoon worms in the suborder Echiurida. It is a monotypic family, the only genus being ''Echiurus''. These worms burrow into soft sediment on the seabed. Species The World Register of Marine Species recognises the following species in the genus:- * '' Echiurus abyssalis'' Skorikow, 1906 * '' Echiurus antarcticus'' Spengel, 1912 * ''Echiurus echiurus ''Echiurus echiurus'' is a species of spoon worm in the family Echiuridae.

picture info	Cosmopolitan Distribution In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so. Killer whales ( orcas) are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between. Such a taxon (usually a species) is said to have a ''cosmopolitan'' distribution, or exhibit cosmopolitanism, as a species; another example, the rock dove (commonly referred to as a ' pigeon'), in addition to having been bred domestically for centuries, now occurs in most urban areas around the world. The extreme opposite of a cosmopolitan species is an endemic (native) species, or one foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Listriolobus Pelodes ''Listriolobus pelodes'' is a species of marine spoon worm. It is found in shallow seas in the North East Pacific off the coast of California. It lives in a burrow in soft sediments. Description ''Listriolobus pelodes'' has a plump, sausage-shaped body about long and wide. An extensible spoon-shaped proboscis projects from the anterior (front) end of the body and the mouth is at its base on the ventral side. There is a pair of hooked setae (bristles) projecting from the ventral surface of the body behind the mouth and a pair of nephridiopores nearby. The anus is at the posterior end of the body. There are two anal vesicles on either side of the rear end of the gut which are used for respiration. The body is a translucent green colour and there are eight longitudinal bundles of muscle in the body wall. Distribution ''Listriolobus pelodes'' is found along the coast of North America ranging from northern California as far south as Baja California at depths between about . It live ...
