Pomphorhynchus laevis is a parasitic acanthocephalan worm that can influence the reaction of its intermediate host, the freshwater amphipod Gammarus pulex, to the smell of potential predators like perch, Perca fluviatilis.
Contents
Life cycle
Pomphorhynchus laevis facilitates its movement from its initial host. Research has demonstrated that organisms affected by the parasite exhibit a diminished or inverted avoidance response to the scent of predators when compared to uninfested specimens, supporting the notion that the parasite manipulates its host, with the goal of passing itself on to its definitive host, a freshwater fish. Affected specimens also demonstrate vibrant changes in color, making them more visible to predators.
Biomimetics
This worm swells its proboscis to press microneedles into the intestinal wall, with a very strong adhesive force. This has inspired a structural skin graft adhesive that sticks strongly but has minimal tissue damage while in place and upon removal.
