Suckermouth-amored catfishes ( Pterygoplichthys spp.) is one of the most widespread invasive species in Vietnam. However, it is relatively unknown how these species have evolved in divergent adaptations to local conditions varying in habitat types, which is essential for managing their invasion in Vietnam. We addressed this by analyzing a large num...
