Talk:Vision in toads

Color vision
I wonder whether toads can distinguish several colors or not, but I didn't find anything about that in the article. Apparently, Ewert didn't investigate that issue, but maybe an expert could provide some information from other sources. Even if the question is still unsettled, that may be worth noting. - Jochen Burghardt (talk) 08:27, 21 March 2014 (UTC)
