Spectral sensitivity of the visual system of endemic Baikal amphipods

Abstract

In this work, we attempted to explore the visual system of Baikal endemic amphipods with behavioral experiments. These data show that a littoral species Eulimnogammarus cyaneus can sense most wavelengths in the human-visible range, while in the case of a deep-water species Ommatogammarus flavus we did not see any response to light.
