The parasite that replaces a fish's tongue with its own living body
In short: The tongue-eating louse is a specialized parasite that consumes a fish's tongue and then permanently occupies the space. This video explores the survival strategies of the Cymothoa exigua, a unique member of a vast family of fish-infesting parasites.
The Cymothoa exigua is one of nearly 400 species within a family of parasites that target fish. While some relatives prefer to feed on blood from gills, latch onto heads, or burrow directly into flesh, this specific louse focuses its efforts on the tongue. By consuming the organ, the parasite effectively takes its place, becoming a permanent fixture in the host's mouth.
Niko Zlotnik examines how these creatures locate their hosts and the evolutionary strategies that allow them to thrive in such a niche environment. Understanding these behaviors offers insight into the diverse and often extreme methods parasites use to secure a home.
