Choanotaenia infundibulum

Choanotaenia infundibulum is a type of tapeworm that is an internal parasite of chickens. C. infundibulum is a 50-200 mm (2-8 in) long flattened, segmented, ribbon-shaped worm that invades the chicken's gastrointestinal system.

Life cycle: C. infundibulum has an indirect life cycle, using flies and beetles as intermediate hosts. Chickens become infected by consuming the C. infundibulum eggs shed in the feces of infected house flies and beetles.
