AbstractThe taxon Gastrotricha includes marine and freshwater species of microscopical size. Traditionally, two subtaxa, Macrodasyida and Chaetonotida, are distinguished. Their phylogenetic position has recently become unresolved, because the traditional concept of a closer relationship to Cycloneuralia (or Ecdysozoa) is not supported by molecular ...

PREFAZIONE Perché un nuovo testo di Zoologia? La risposta sta innanzitutto nella quantità di nuove informazioni, derivanti dagli studi basati sull’uso di approcci cladistici e molecolari, che hanno rivoluzionato le nostre conoscenze sui rapporti filogenetici tra gli animali, soprattutto invertebrati.

Gastrotricha are microscopic (0.6–3.0 mm in body length) aquatic invertebrates closely related to Nematoda, with most of which they share a meiobenthic life style. In marine habitats they are mainly interstitial whereas in fresh waters they are an important component of the periphyton and benthos; members of three freshwater families are semipelagic ...

The Behavior of Heterolepidoderma sp. (Gastrotricha)
Zoological Science, 1998The behavior of Heterolepidoderma sp. was studied with the same approach as those already used for many species of ciliates. The ethogram we drew comprehends both helicoidal swimming (n = 20, r = 52.5 +/-12.2 mum, pitch = 512 +/- 101 mum, v--> = 215 +/- 43 mum/sec), periodically interrupted by irregular patterns changing the direction of the swimming ...
