Gastrotricha.

2002
Gastrotricha are an important component of the benthos and periphyton of freshwater habitats, where they can reach densities of up to 100 ind/10 cm-2. However, due to their small size and the difficulties met in their study, gastrotrichs, and especially aspects of their reproduction and ecology, are still poorly known.Gastrotricha are aschelminthes ...
