Nereis Onychophora
''Nereis onychophora'' is a polychaete worm of the phylum Annelida. The type locality is in the Seram Sea, Indonesia. Etymology The specific epithet, ''onychophora'' , is from grc, ονυχής (transliterated ; meaning ''claws'') and (transliterated ; meaning ''to carry''). It shares this name with the phylum Onychophora. Description The following is the original description of ''N. onychophora'', from Horst (1918): ''Among the plankton-worms, collected at the above-named station, I met with a male ''Heteronereis'', that is characterized by having in the anterior (agamous) body-region, the notopodial fascicle represented by a single, stout, yellow bristle, with a dark brown, hook-shaped apex; the neuropodial fascicle has its usual appearance and contains in its dorsal part some homogomph setigerous bristles and some heterogomph falcigerous ones, whereas ventrally there occur only falcigerous setae, with a terminal piece, that is ciliated along its whole border.

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 fresh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seram Sea
The Seram Sea or Ceram Sea ( id, Laut Seram) is one of several small seas between the scattered islands of Indonesia. It is a section of the Pacific Ocean with an area of approximately located between Buru and Seram, which are two of the islands once called the South Moluccas. These islands are the native habitat of plants long coveted for their use as spices, such as nutmeg, cloves, and black peppercorns, and the seas surrounding them were busy shipping routes. The Seram Sea is also the habitat of several species of tropical goby and many other fish. Like many other small Indonesian seas, the Seram Sea is rocky and very tectonically active. Extent The International Hydrographic Organization (IHO) defines the Seram Sea as being one of the waters of the East Indian Archipelago. The IHO defines its limits as follows: ''On the North and Northeast.''

Indonesia
Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania between the Indian and Pacific oceans. It consists of over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea. Indonesia is the world's largest archipelagic state and the 14th-largest country by area, at . With over 275 million people, Indonesia is the world's fourth-most populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population. Indonesia is a presidential republic with an elected legislature. It has 38 provinces, of which nine have special status. The country's capital, Jakarta, is the world's second-most populous urban area. Indonesia shares land borders with Papua New Guinea, East Timor, and the eastern part of Malaysia, as well as maritime borders with Singapore, Vietnam, Thailand, the Philippines, Australia, Palau, and India ...

Onychophora
Onychophora (from grc, ονυχής, , "claws"; and , , "to carry"), commonly known as velvet worms (due to their velvety texture and somewhat wormlike appearance) or more ambiguously as peripatus (after the first described genus, '' Peripatus''), is a phylum of elongate, soft-bodied, many-legged panarthropods. In appearance they have variously been compared to worms with legs, caterpillars, and slugs. They prey upon other invertebrates, which they catch by ejecting an adhesive slime. Approximately 200 species of velvet worms have been described, although the true number of species is likely greater. The two extant families of velvet worms are Peripatidae and Peripatopsidae. They show a peculiar distribution, with the peripatids being predominantly equatorial and tropical, while the peripatopsids are all found south of the equator. It is the only phylum within Animalia that is wholly endemic to terrestrial environments, at least among extant members. Velvet worms are generally c ...

Phyllodocida
Phyllodocida is an order of polychaete worms in the subclass Aciculata. These worms are mostly marine, though some are found in brackish water. Most are active benthic creatures, moving over the surface or burrowing in sediments, or living in cracks and crevices in bedrock. A few construct tubes in which they live and some are pelagic, swimming through the water column. There are estimated to be more than 4,600 accepted species in the order. Characteristics Phyllodocida are segmented worms and range in size from a few millimetres long to over a metre. Each segment bears a pair of paddle-like parapodia. The prostomium generally has one or two pairs of eyes, a dorsal pair of antennae, a ventral pair of sensory palps and a pair of organs on the neck. The peristomium is a ring, often hidden dorsally by the prostomium and the first segment. There is a muscular proboscis with one or more pairs of jaws. The next few segments tend to differ from those further back in having enlarged do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
