While most birds and mammals serve as hosts for lice, there are specific animals that are not known to be infested by them. According to scientific observations, lice have not been found on the following animals:
- Platypuses (duckbills)
- Anteaters
- Armadillos
- Bats
- Whales
The absence of lice on these species is notable, as Phthiraptera are otherwise obligate, permanent ectoparasites that have successfully adapted to a wide variety of avian and mammalian hosts.1
