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 ]
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.
Many land planarian species described during the second half of the 19th century and the first half of the 20th century were classified based solely on external characters. Currently, the land planarian genera are highly based on their internal anatomy, especially the anatomy of the copulatory apparatus. As a result, species with old ...
Caenoplana variegata is a species of land planarian. [1] It was first described in 1888 as Geoplana variegata by Joseph James Fletcher and Alexander Greenlaw Hamilton. [1] [2] The currently accepted name is Caenoplana variegata [1] [3] although the name accepted by Australian authorities is Australopacifica variegata. [4]
During most of the 20th century, many new land planarian species, mostly from Australia and South America, were placed in Geoplana. In 1955, Eudóxia Maria Froehlich defined that Geoplana vaginuloides would be the type-species of Geoplana , as it was the first species listed by Stimpson.
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.
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 ...
