Morphological measurements of six cave and nine surface Asellus aquaticus populations

The dataset contains data of 17 functional morphological traits measured on 656 individuals from the Asellus aquaticus species complex from six cave and nine surface populations from four countries. The measured traits are covering a wide range of functionalities including locomotion, fecundity and sensing. By including individuals from both sex, and from surface and cave habitats questions concerning troglomorphic adaptation and sexual dimorphism and their interaction can be addressed.
