Planarians (triclads) are free-living flatworms of the class Turbellaria, [2] [3] ... The mouth is located in the middle of the underside of the body, which is ...
Land planarians are carnivorous and most species are active predators, but some are mainly scavengers. [22] All planarians feed through a muscular and eversible pharynx located slightly posteriorly to the middle of the body length and opening through a ventral mouth. The pharynx is an extensible tube-like organ bearing a complex muscular coat.
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 ...
Luteostriata abundans is a small to medium-sized land planarian with an elongate body and parallel margins. The largest specimens have a length of about 60 millimeters or more. The largest specimens have a length of about 60 millimeters or more.
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 ...
Most adult individuals of B. adventitium are 5–8 cm (2.0–3.1 in) in length. The head is expanded and fan-shaped, being easily distinguishable from other common species of Bipalium, such as Bipalium kewense and Bipalium pennsylvanicum, because these have a head in the shape of a half moon. [1]
The first species of Luteostriata was described in 1857 by Max Schultze and Fritz Müller as a Brazilian yellow planarian with a broad black longitudinal stripe in the middle of the back and a narrow deep orange stripe on each side of it. [5] They identified it as Planaria elegans, a species described by Darwin, and put it in their new genus ...
Planaria is a genus of planarians in the family Planariidae. Due to its excellent ability to regenerate, species of Planaria has also been used as model organisms in regeneration studies. [ 1 ] When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual. [ 2 ]
