Gastrotricha

Filum **Gastrotricha** (), adalah kelompok hewan mikroskopis (0,06-3,0&nbsp;mm), seperti cacing, pseudoselomata, dan terdistribusi secara luas dan melimpah di air tawar dan lingkungan laut. Mereka sebagian besar bentik dan hidup dalam perifiton, lapisan organisme kecil dan detritus yang ditemukan di dasar laut dan tempat dasar badan air lainnya. Mayoritas hidup di dan di antara partikel sedimen atau pada permukaan terendam lain, tetapi beberapa spesies terestrial dan hidup di darat dalam lapisan air di sekitar butir tanah. Gastrotricha dibagi menjadi dua ordo, Macrodasyida yang laut (kecuali untuk dua spesies), dan Chaetonotida, beberapa di antaranya adalah laut dan beberapa air tawar. Hampir delapan ratus spesies gastrotricha telah dijelaskan.

## Klasifikasi
