Platyhelminthes (from the Greek πλατύ, platy, meaning "flat" and ἕλμινς (root: ἑλμινθ-), helminth-, meaning "worm") [4] is a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates commonly called flatworms or flat worms.
Pseudoceros are simultaneous hermaphrodites [9] and reproduce sexually via random hypodermic insemination through the body tissue. [10] These organisms participate in penis fencing, [9] which is a behavior where the flatworms use their extended penises to stab and inseminate the other, while avoiding becoming inseminated themselves.
The Turbellaria are one of the traditional sub-divisions of the phylum Platyhelminthes (flatworms), and include all the sub-groups that are not exclusively parasitic.There are about 4,500 species, which range from 1 mm (0.039 in) to large freshwater forms more than 500 mm (20 in) long [3] or terrestrial species like Bipalium kewense which can reach 600 mm (24 in) in length.
Pseudocerotidae is a family of flatworms which includes the Bedford's flatworm. Pseudocerotidae are simple organisms categorized by their oval bodies and tentacles [7] and bright colors. They use the cilia to glide along surfaces. [8] Most commonly referred to as marine flatworms, closely related to the orders Macrostomorpha and Lecithoepitheliata.
Planarians are bilaterian flatworms that lack a fluid-filled body cavity, and the space between their organ systems is filled with parenchyma. [5] [13] Planarians lack a circulatory system, and absorb oxygen through their body wall. They uptake food to their gut using a muscular pharynx, and nutrients diffuse to internal tissues.
In areas where the land snail population has been exhausted, it has been known to eat other flatworms. [7] The diet of Platydemus manokwari is also affected seasonally. According to studies done by Sugiura, more than 90% of the land snails were preyed upon by P. manokwari in the period from July to November, and only 40% of the land snails were ...
