Species Composition of Scaly-Headed Gunnels (Pholidae) in Russian Waters
摘要
Abstract
Analyses of morphological characters of the scaly-headed gunnels reveal that Russian waters are inhabited by only one species from this group, Pholis crassispina, while Ph. nebulosa is absent. The article also provides values of important diagnostic characters for both species and clarifies the range of Ph. crassispina in Russian waters.
