The Bryozoa or ectoprocta are small benthic, sessile, aquatic invertebrates growing as colonies of connected zooids on submerged substrates, feed on suspended organic particles which they captured by the whorls of ciliated tentacles (lophophore). Globally about 94 bryozoan species are found in freshwater, consisting of 24 genera and 10 families (Massard & Geimer, 2008).

Abstract

The Karnataka State of India has a 270 km long coast line bordering Arabian Sea. The habitats are mainly sandy with scattered rocks and rocky islands. The echinoderm fauna of the coast is poorly known. There are several scattered reports of echinoderms from Karnataka (see Sastry, 2007). However, the report of Patil (1953) includes the marine fauna exclusively of Karnataka and only Temnopleurus sp. of echinoderms from Karwar coast of Karnataka.
