Views Read Edit View history. Polychaetes have a varying number of protonephridia or metanephridia for excreting waste, which in some cases can be relatively complex in structure.

More than 10, species are described in this class. November Learn how and when to remove this template message.

However, polychaetes vary widely from this generalised pattern, and can display a range of different body forms. The gonads shed immature gametes directly into the body cavity, where they complete their development. Species recognized by the World Register of Marine Species: Most burrow or build tubes in the sediment, and some live as commensals. Proceedings of the Royal Society B.

Groups that may be descended from the polychaetes include the oligochaetes earthworms and leechessipunculansand echiurans. Each of the epitoke segments is packed with eggs and sperm and features klasifiikasi single eyespot on its surface. Normally, these have a deep red sheen, warning off predators, but when the light shines on them perpendicularly, they flush green and blue, a “remarkable example of photonic engineering by a living organism”.


An Encyclopedia of Curious and Unusual Animals. The name of the genus is taken from Aphrodite annnelida, the Ancient Greek goddess of love.

Annelida – Wikipedia

The body of the sea mouse is covered in a dense mat of parapodia and setae hairlike structures. The English name may either have a similar meaning, or may derive from the supposed resemblance to a bedraggled mouse when washed up on shore.

Bundles of bristles, called setaeproject from the parapodia. For the Ancient Greek goddess, see Aphrodite. Tubifex can be easily cultured on mass scale in containers with to mm thick pond mud at the bottom, blended with decaying vegetable matter and masses of bran and bread. Tubifex is a cosmopolitan genus of tubificid annelids that inhabits the sediments of lakesrivers and occasionally sewer lines.

In general, however, they possess a pair of jaws and a pharynx that can be rapidly everted, allowing the worms to grab food and pull it into their mouths. Underneath this, in order, are a thin layer of connective tissue, a layer of circular muscle, a layer of longitudinal muscle, and a peritoneum surrounding the body cavity.

Each segment bears a pair of paddle-like and highly vascularized parapodiawhich ahnelida used for movement and, in many species, act as the worm’s primary respiratory surfaces. Underwater polychaetes have eversible mouthparts used to capture prey. Retrieved 9 August The blood may be colourless, or have klasiikasi of three different respiratory pigments.


In mature specimens, the reproductive organs are clearly found on the ventral side of the body. Two mature Tubifex worms undergo copulation by joining their ventral and anterior surfaces together with their anterior ends pointing opposite directions. The outer surface of the body wall consists of a simple columnar epithelium covered by a thin cuticle.

From Wikipedia, the free encyclopedia. Aphrodita Linnaeus[1]. Additionally, they are very difficult for some fish to obtain in the wild, so certain fish, such as Rift Valley cichlids, will obsessively consume them until they make themselves sick. After copulation, they separate and begin annelidaa produce klasifikadi cases containing eggs, called cocoons.

These minute reproductive organs are attached to the ventral side of the body wall in the celomic cavity. Once mature, the gametes are shed into the surrounding water through ducts or openings that vary between species, or in some cases by the complete rupture of the body wall and subsequent death of the adult.

Within 15 days, clusters of worms develop and can be removed with mud in masses.
