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 ]
Each planarian transports its secretion to the other planarian, giving and receiving sperm. Eggs develop inside the body and are shed in capsules. Weeks later, the eggs hatch and grow into adults. In asexual reproduction, the planarian fissions and each fragment regenerates its missing tissues, generating complete anatomy and restoring ...
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 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.
Planaria torva is a species of planarian in the family Planariidae. [1] When an individual is cut into pieces, each piece has the ability to regenerate into a fully ...
Convolutriloba retrogemma is a reddish-brown flatworm 2 mm in length also commonly known as redbug, red planaria, rust flatworm, or simply red flatworm. It is a marine flatworm that gets energy from its endosymbiotic algae or from the consumption of small invertebrates such as copepods and rotifers.
The killer also left behind a cryptic message at the scene, with the words “deny,” “depose,” and “defend” inscribed on live rounds and shell casing left outside.
Bipalium species are predatory.Some species prey on earthworms, while others may also feed on mollusks. [10] [11] These flatworms can track their prey. [12]When captured, earthworms begin to react to the attack, but the flatworm uses the muscles in its body, as well as sticky secretions, to attach itself to the earthworm to prevent escape.
