Data from: Ontogenetic adaptations in the visual systems of deep-sea crustaceans

For all visually competent organisms, the driving force behind the
adaptation of photoreceptors involves obtaining the best balance of
resolution to sensitivity in the prevailing light regime, as an increase
in sensitivity often results in a decrease in resolution. A number of
marine species have an additional problem to deal with, in that the
juvenile stages live in relatively brightly lit shallow (100–200 m depth)
waters, whereas the adult stages have daytime depths of more than 600 m,
where little downwelling light remains. Here, I present the results of
electrophysiological analyses of the temporal resolution and irradiance
sensitivity of juvenile and adult stages of two species of ontogenetically
migrating crustaceans (Gnathophausia ingens and Systellaspis debilis) that
must deal with dramatically different light environments and temperatures
during their life histories. The results demonstrate that there are
significant effects of temperature on temporal resolution, which help to
optimize the visual systems of the two life-history stages for their
respective light environments.
