Bdellocephala Bathyalis
''Bdellocephala'' is a genus of freshwater triclad that inhabits different regions of Eurasia.Kawakatsu, M., Sluys R., Timoshkin O. A., Naumova T. V., Nishino M., & Takai M. (2001). Redescription of Japanese Bdellocephala annandalei from Lake Biwa-ko with comparative redescription of the Far Eastern and Kamchatkan Bdellocephala species (Tricladida, Paludicola). Belgian Journal of Zoology. 131, 205-211. Description As in other genera of the family Dendrocoelidae, species of ''Bdellocephala'' have an anterior adhesive organ. However, differently from other dendrocoelids, species of ''Bdellocephala'' lack a well-developed penis papilla in the male copulatory apparatus, which is uncommon in freshwater planarians.

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilateral symmetry, bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and th ...

Platyhelminthes
The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food cannot be processed continuously. In traditional medicinal texts, Platyhelminthes are divided into Turbellaria, which are mostly non-parasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been proven not to be monop ...
