Table 5 Aspect ratio of the hamuli of Gyrodactylus spp. infecting goodeid and poeciliid fishes

From: To each his own: no evidence of gyrodactylid parasite host switches from invasive poeciliid fishes to Goodea atripinnis Jordan (Cyprinodontiformes: Goodeidae), the most dominant endemic freshwater goodeid fish in the Mexican Highlands
