Our results show that nocturnal geckos are able to dis-
criminate colours in very dim light. Exactly what they use
this ability for and precisely how well they see colour,
remains to be investigated. Geckos are only the second ani-
mal group after a nocturnal hawkmoth (Kelber et al. 2002)
that have been proved to see colour when we are colour-
blind. However, this remarkable ability may be more com-
mon than we thought.
