Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. [ 2 ] These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. [ 3 ]
Bipalium is a genus of large predatory land planarians. They are often loosely called "hammerhead worms" or "broadhead planarians" because of the distinctive shape of their head region. Land planarians are unique in that they possess a "creeping sole", a highly ciliated region on the ventral epidermis that helps them to creep over the substrate ...
Formerly, the Tricladida was split according to their habitat: Maricola (marine planarians); Paludicola (freshwater planarian); and Terricola (land planarians). [9] Planarians move by beating cilia on the ventral dermis, allowing them to glide along on a film of mucus. Some also can move by undulations of the whole body by the contractions of ...
Bipalium kewense, also known as the shovel-headed garden worm, is a species of large predatory land planarian with a cosmopolitan distribution. [1] [2] It is sometimes referred to as a "hammerhead flatworm" due to its half-moon-shaped head, but this name is also used to refer to other species in the subfamily Bipaliinae.
The complete mitogenome of Caenoplana coerulea is 18,621 bp in length. [7] Its main characteristic is a cytochrome c oxidase subunit 2 gene of unusual length, with a cox2 encoded protein 505 aa in length (compared to about 250 aa in other geoplanids); this characteristic of a very long cox2 is also found in other members of the subfamily Rhynchodeminae, to which Caenoplana coerulea belongs.
The subfamily Geoplaninae was initially defined by Ogren and Kawakatsu (1990) [4] for land planarians which have a broad creeping sole, mouth in the second half of the body, dorsal testes, subepithelial longitudinal musculature well developed and parenchymal longitudinal musculature absent or not well developed. The eyes contour the anterior ...
Kontikia is a genus of land planarians native from islands in the Indo-Pacific region, but several species have been introduced elsewhere. [1] Description
The genus Timyma includes planarians of elongate body and spatula-like anterior end. Although most land planarians native from South America have dorsal testes, Timyma has ventral testes, which at first suggested that it is related to the Australasia species of the tribe Caenoplanini. [1]
