Lernaea [Lernaea]

Description

Lernaea is one of the most well-known genera within the Lernaeidae family, comprising species commonly referred to as anchor worms. These copepods are external parasites of freshwater fish, easily recognizable by their long, thread-like body and the anchor-shaped appendages they use to secure themselves to the host. Lernaea species can cause severe damage to fish, leading to infections, reduced growth, and even mortality, posing a threat to wild and cultured fish populations.
