Definition of Gastrotricha in English: Gastrotrichaplural noun ˌɡastrəˈtrʌɪkəɡasˈträtrikə Zoology A small phylum of minute aquatic wormlike animals that bear bristles and cilia. They are thought to be related to the nematode worms and rotifers. 〔动〕腹毛动物门 Example sentencesExamples - With the two examples from Nematomorpha and Gastrotricha I aimed to exemplify these interconnections and show gaps in knowledge that are mainly due to the evaluation of nematomorphs and gastrotrichs as ‘lesser known groups.’
- Furthermore they have several plesiomorphic characters, such as a myoepitheal pharyngeal bulb, comparable to the other Cycloneuralia, especially the Nematoda and Gastrotricha.
- These are the horsehair worms or Nematomorpha and the Gastrotricha.
- The name Gastrotricha derives from the possession of ventral locomotory cilia which are covered by cuticle, a unique feature among metazoan animals.
- They concluded that Gastrotricha is the sister-taxon of a monophyletic clade comprising Nematoda, Nematomorpha, Priapulida, Kinorhyncha and Loricifera.
Derivativesnoun ˈɡastrətrɪk Zoology Furthermore, the micrognathozoans have two rows of multiciliated cells that forms a locomotory organ, similar to that in some gastrotrichs and interstitial annelids. Example sentencesExamples - With the two examples from Nematomorpha and Gastrotricha I aimed to exemplify these interconnections and show gaps in knowledge that are mainly due to the evaluation of nematomorphs and gastrotrichs as ‘lesser known groups.’
- There are also a number of differences, however, perhaps most important of which is the observation of a clade consisting of the gastrotrichs plus platyheminthes that is basal to all other lophotrochozoan taxa.
- The body cavity nature varies considerably in these phyla, from complete absence of body cavity in the entoprocts and gastrotrichs to the priapulid body cavity that is actually interpreted as a true coelom by some authors.
- A gastrotrich (meaning ‘hairy stomach’) uses myriad hairs over its head and belly to glide, wriggle, and squirm, looking for food.
