Worm
Worms are many different distantly related bilateral animals that typically have a long cylindrical tube-like body, no limbs, and no eyes (though not always). Worms vary in size from microscopic to over in length for marine polychaete worms (bristle worms); for the African giant earthworm, ''Microchaetus rappi''; and for the marine nemertean worm (bootlace worm), ''Lineus longissimus''. Various types of worm occupy a small variety of parasitic niches, living inside the bodies of other animals. Free-living worm species do not live on land but instead live in marine or freshwater environments or underground by burrowing. In biology, "worm" refers to an obsolete taxon, ''vermes'', used by Carolus Linnaeus and Jean-Baptiste Lamarck for all non-arthropod invertebrate animals, now seen to be paraphyletic. The name stems from the Old English word ''wyrm''. Most animals called "worms" are invertebrates, but the term is also used for the amphibian caecilians and the slowworm '' A ...

Chaetonotida
The Chaetonotida is an order of gastrotrichs. They generally have a tenpin or bottle-like shape. Chaetonotids inhabit both freshwater and marine environments. They can be distinguished from other gastrotrichs by the absence of pores in the pharynx, and by the presence of adhesive glands at the posterior end of the animal only. Most freshwater species are parthenogenetic Parthenogenesis (; from the Greek grc, παρθένος, translit=parthénos, lit=virgin, label=none + grc, γένεσις, translit=génesis, lit=creation, label=none) is a natural form of asexual reproduction in which growth and development .... The smooth or complex cuticle has a variable number of adhesive tubes, and the pharyngeal lumen of Chaetonotids is Y-shaped. A valve may be present at the junction of the pharynx and midgut. The epidermis in most organisms in this order is partly syncytial. The Chaetonotids are divided into two suborders, Multitubulatina and Paucitubulatina. Multitubulatina are ...
