They may have a tough time wooing princesses, but new research reveals a princely ocular skill that sets frogs apart
Professor Almut Kelber told OT that the research answered a longstanding question in visual physiology.
“The function of the second rod type in frogs and toads had not been known before, and it was not clear whether they could be used for colour vision,” she explained.
Further research will focus on whether all types of frogs and toads have exceptional night vision.
“The existence of these special rods has only been proven for a very few species of toads and frogs. We do not know if they exist in all species, specifically in the day-active species,” Professor Kelber concluded.
