Annelids
The annelids (Annelida , from Latin ', "little ring"), also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The Annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polychae ...

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] |
Aphrodita
''Aphrodita'' is a genus of ocean, marine polychaete worms found in the Mediterranean sea and the eastern and western Atlantic Ocean. Several members of this genus are known as "sea mice". Etymology The name of the genus is taken from Aphrodite, the Ancient Greek goddess of love, said to be because of a supposed resemblance to human female genitalia. The English name may derive from the resemblance to a bedraggled house mouse when washed up on shore. Description The body of the sea mouse is covered in a dense mat of parapodia and ''wikt:seta, setae'' (hairlike structures). Adults generally fall within a size range of , but some grow to . The sea mouse has two pairs of feeler-like appendages close to the mouth and does not have eyes. Locomotion is carried out by several small, bristly, paddle-like appendages. They are hermaphroditic which means that they have functional reproductive organs of both sexes. The eggs of one individual are fertilised by the sperm of another. St ...
