Ectoparasite:
Ectoparasites are defined as parasites that infest the outer surface of their hosts, which can include species that live exclusively on humans, such as lice and scabies, as well as those that are incidental hosts, like fleas. They can cause intense itching and may transmit diseases through their bites. [ScienceDirect]
