While living in and on the host species, the animal parasite has evolved certain adaptations. Describe these adaptations with examples.
In accordance with their life styles, parasites evolved special adaptations.
These are the loss of unnecessary sense organs, presence of adhesive organs or suckers to cling on to the host (e.g. suckers in tape worm), loss of digestive system (e.g. tapeworm) high reproductive capacity (e.g. roundworm).
