On the right whale, the parasites live mainly on callosities (raised callus-like patches of skin on the whales' heads).

The lice predominantly eat algae that settle on the host's body ...

Cymothoa exigua, or the tongue-eating louse, is a parasitic isopod of the family Cymothoidae. It enters a fish through the gills. The female attaches to the tongue, while the male attaches to the gill arches beneath and behind the female. Females are 8–29 mm (0.3–1.1 in) long and 4–14 mm (0.16–0.55 in) wide.
