A planarian is one of many flatworms of the Turbellaria class. It is also the common name for a member of the genus Planaria within the family Planariidae.Sometimes it also refers to the genus Dugesia. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers.n asexual reproduction, the planarian detaches its tail end and each half regrows the lost parts by regeneration, allowing neoblasts (adult stem cells) to divide and differentiate, thus resulting in two worms. Some species of planaria are exclusively asexual, whereas some can reproduce both sexually and asexually.
Planarians are free-living, primarily carnivorous flatworms-with a three-branched digestive cavity. Planarians may eat other living, as well as dead, invertebrates, detritus or decaying organic matter, and some prefer diatoms.I feed my planarians egg yolk and bits of beef liver.It is fun to see their gastrovascular cavity filled with egg yolk after a big meal! Most are freshwater forms, but marine and terrestrial planarians exist. White, gray, brown, black, and green or sometimes transparent, planarians range in size from 1/8 to 1 in.mail:Planarians@stevesauter.com. O ne class of the phylum Platyhelminthes or flatworms is free-living, that is, not parasitic. These are the Turbellaria. These soft, flat worms are widely distributed over land, sea and fresh waters.
