Description

Anika Preuss and co-authors study how the seal louse clings to diving seals without being torn off. Their 2025 paper compares the louse's legs with those of the human head louse, a land-based relative. The seal louse endures deep pressure, strong drag, salt water, and shifting temperatures on its host.

Using X-ray tomography and laser microscopy, the team found a compact, sturdy leg design. The louse has a fused lower leg segment, an extra set of leg muscles, and a shortened claw tendon, a trait not seen in other insects. These traits boost grip force while saving energy. Tests showed the louse moves well only on hair-like surfaces, tying it fully to host fur.
