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.
Hirudinea, whose name means "leech-shaped" and whose best known members are leeches. [8] Marine species are mostly blood-sucking parasites, mainly on fish, while most freshwater species are predators. [13] They have suckers at both ends of their bodies, and use these to move rather like inchworms. [15]
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida.They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract.
Two planarian species have been used successfully in the Philippines, Indonesia, Hawaii, New Guinea, and Guam to control populations of the imported giant African snail Achatina fulica, which was displacing native snails. However, these planarians are themselves a serious threat to native snails and should not be used for biological control.
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]
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 ...

The subclass Hirudinea (leeches) contains three orders with various habitat preferences. Branchiobdellida are commensal with freshwater crayfish, grazing algae from their exoskeletons. Acanthobdellida are parasitic on freshwater fishes such as grayling. Leeches can be found in nearly every part of the world, in freshwater, terrestrial, and ...
