louse
Human head louse (Pediculus humanus).
The elephant louse (Haematomyzus) is uniquely adapted for feeding on hosts with thick skin, such as elephants and warthogs. While it is classified as a chewing louse, it possesses specialized mouthparts that are intermediate between those of chewing and sucking lice.12
These adaptations include:
- Modified Mandibles: The louse features modified mandibles located at the end of a long, specialized proboscis.2
- Piercing Capability: Unlike typical chewing lice that feed on skin debris or secretions, the elephant louse has mouthparts specifically evolved to pierce the thick skin of its host.1
This specialized structure allows the insect to access its food source despite the significant physical barrier presented by the host's hide.1
