Summary

The noctural desert elapid Walterinnesia aegyptia Lataste was observed in the habitat and in captivity. This species is of extremely poor sight and finds its prey mainly by its olfactory sense. It is active around midnight at temperatures down to 10°C and collects various kinds of diurnal and crepuscular reptiles, which are pulled out of their hidingplaces. Its extremely semantic coloration serves as a defense device and does not come in to conflict with its specialized way of foraging.
