How long does the Cymothoa exigua live?

Cymothoa exigua, commonly known as the tongue-eating louse, typically has a lifespan of about 2 to 3 years. This parasitic isopod attaches itself to the tongues of fish, replacing the tongue over time. Its life cycle involves several stages, and it thrives in the host's mouth, feeding on blood and tissue. The duration of its life can vary based on environmental conditions and the health of its host.
