Most other species have external gills, often associated with the parapodia. These are typically fairly simple structures, capable of distinguishing only light and dark, although some species have large annnelida with lenses that may be capable of more sophisticated vision.

The blood vessels themselves are contractile, helping to push the blood along, so most species have no need of a heart. Some polychaetes exhibit remarkable reproductive strategies. Tubifex worms are often klazifikasi as a live food for fish, especially tropical fish and certain other freshwater species. These minute reproductive organs are attached to the ventral side of the body wall in the celomic cavity.

Soon, the Tubifex worm withdraws its body from the egg case by its backward abnelida movements. Groups that may be descended from the polychaetes include the oligochaetes earthworms and leechessipunculansand echiurans.

Although the Tubifex worms are hermaphroditesthe male k,asifikasi female organs become mature at different times; thus self-fertilization is avoided, and cross-fertilization is encouraged. Tubifex is a cosmopolitan genus of tubificid annelids that inhabits the sediments of lakesrivers and occasionally sewer lines. This page was last edited on 15 Decemberat Revealed by a snake camera inspection of sewer piping under the Cameron Village shopping center, videos of the creature went viral on YouTube in under the name “Carolina poop monster”.


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 Lamarck Once mature, the gametes are shed into the surrounding water klasitikasi 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. The digestive tract is a simple tube, usually with a klasifikqsi part way along. The eye spots sense when the epitoke reaches the surface and the segments from millions of worms burst, releasing their eggs and sperm into the water.

However, polychaetes vary widely from this generalised pattern, kllasifikasi can display a range of different body forms.

Lastly, in poorly cleaned aquaria, Tubifex can become established as a pest species, covering the bottom of the aquarium in a thick carpet which may be considered unsightly.

Retrieved from ” https: In other projects Wikimedia Commons Wikispecies. The head, or prostomiumis relatively well developed, compared with other annelids. The head also includes a pair of antennaetentacle-like palpsand a pair of pits lined with ciliaknown as “nuchal organs”. This risk can be partially solved by keeping the worms under brisk running water until they have voided klasitikasi contents of their digestive systems.


klasifikadi The cocoon is formed around the clitellum as a soft, box-like structure into which the ova and the sperm are deposited. Polychaetes are extremely variable in both form and lifestyle, and include a few taxa that swim among the plankton or above the abyssal plain. Retrieved April 26, The name of the genus is taken from Aphroditethe Ancient Greek goddess of love.

The effect is produced by many hexagonal cylinders within the spines, which “perform much more efficiently than annlida optical fibres “. For the Ancient Greek goddess, see Aphrodite. Wikimedia Commons has media related to Polychaeta.

The two main blood vessels furnish smaller vessels to supply the parapodia and the gut. When harvested from sewers, open bodies of anneliea, and even from hatcheries, they may be infected with various diseases. World Register of Marine Species. The blood may be colourless, or have any of three different respiratory pigments.

At this stage, the sperm of one worm is passed into the spermathecae of the other worm.
