Syllidae
Syllidae, commonly known as the necklace worms, is a Family (biology), family of small to medium-sized polychaete worms. Syllids are distinguished from other polychaetes by the presence of a muscular region of the anterior digestive tract known as the ''proventricle''. Syllid worms range in size from to . Most syllids are benthic organisms that transition to a pelagic epitoke for reproduction. They are found in all regions of the ocean, from the intertidal zone to the deep sea, and are especially abundant in shallow water. They are found in a range of habitats, moving actively on rock and sandy substrates, hiding in crevices and among seaweeds, and climbing on sponges, corals, hydrozoans, seagrasses and mangroves. They are generalist feeders. A young Syllid was one of the first worms to be found with pollen from seagrass in its stomach, making it a possible pollinator. The ''proventricle'', Syllid worm's most distinctive anatomical feature, allows the worm to feed by sucking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Syllis Ramosa
''Syllis ramosa'' is a species of polychaete worm in the family Syllidae. It is found in the deep sea where it lives within the tissues of a sponge. It was the first branching polychaete worm to be discovered, with each worm having a single head and multiple anuses. History During the period 1872 to 1876, the Royal Navy's HMS ''Challenger'' was used in the ''Challenger'' expedition to survey and explore the world's oceans. One of the unknown animals dredged from the ocean depths near the Philippines was a species of sponge which was found to contain numerous branching worms inside its cavities. In 1879, one of these worms was formally described by the Scottish marine biologist William Carmichael McIntosh, who named it ''Syllis ramosa''. Branching polychaete worms were previously unknown. Distribution This bristle worm was first discovered living commensally with a sponge at a depth of about near the Philippines and at a depth of in the Arafura Sea. Further branching worms h ...

Polychaete Worm
Polychaeta () is a paraphyletic class of generally marine annelid worms, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm (''Arenicola marina'') and the sandworm or clam worm ''Alitta''. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extremely high temperatures near hydrothermal vents. Polychaetes occur throughout the Earth's oceans at all depths, from forms that live as plankton near the surface, to a 2- to 3-cm specimen (still unclassified) observed by the robot ocean probe ''Nereus'' at the bottom of the Challenger Deep, the deepest known spot in the Earth's oceans. Only 168 species (less than 2% of all polychaetes) are known from fres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramisyllis
''Ramisyllis'' is a small genus of polychaete annelid marine worms. Both species are characterised by their branching body plans. Both species are found in shallow water, with ''R. multicaudata'' native to Darwin Harbour, Australia, and ''R. kingghidorahi'' native to the Sea of Japan near Sado Island, Japan Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asia, Asian mainland, it is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea ....

Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from the Ancient Greek word (), meaning "the depths". Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here, known as bottom dwellers, generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the ...
