Sensitivities of the Sandhopper eye

A recurring theme of posts here is that an understanding of behaviour requires knowledge of (amongst other things) the sensory apparatus available to the navigating animal. Ugolini et al add to their extensive studies of the Sandhopper with a characterisation of the spectral photoresponses of its compound eyes. A strong UV-blue sensitivity is confirmed, which may be the channel for celestial compass information. Allied with a green channel, this is likely to provide the sandhopper with a visual system ideally suited for identifying terrestial landmarks, the use of which has been previously demonstrated by this group.
