Morphometric and meristic variability in lampreys of the genus Lethenteron (Petromyzontida: Petromyzontiformes) in Sakhalin Island rivers
2018
Abstrakt
The occurrence of lampreys of the genus Lethenteron (Cephalaspidomorphi, Petromyzontiformes, Petromyzontidae) in nineteen rivers and one lake in Sakhalin Island is documented in this chapter of the book. Morphometric parameters in larvae and adult specimens from the selected areas are compared using statistically significant differences.
Sex differences in adults in respect to morphometric parameters are also presented.
