petrushkagoogol Posted July 10, 2017 Report Share Posted July 10, 2017 Humans can see in color, bulls in B/W. Is there any animal which can see in monochrome ? eg) only blue. Would such an animal be able to survive on Earth ? Quote Link to comment Share on other sites More sharing options...
JMJones0424 Posted July 11, 2017 Report Share Posted July 11, 2017 Bulls don't see in black and white. They, like most mammals, are di-chromatic, meaning they see colors in much the same way that red-green colorblind humans do. Animals with monochromatic vision do exist. For what it's worth, black and white color vision is monochromatic. It is very rare in humans, but it does exist. In other animals, it is common in marine mammals.

connorbro Posted July 27, 2017 Report Share Posted July 27, 2017 I wonder what color vision bugs and insects have. Quote Link to comment Share on other sites More sharing options...
exchemist Posted July 28, 2017 Report Share Posted July 28, 2017 I wonder what color vision bugs and insects have. My understanding is that bees have excellent colour vision and can see part of the ultra-violet. They need this to be effective at finding the nectar in flowers. Conversely, flowers are coloured to attract pollinating insects, which would not work if they did not see in colour. Bumble bees seem especially attracted to the colour yellow, as demonstrated in my largely yellow kitchen, when the door is open on warm days. I regularly have to capture bumble bees (with a glass jar and a piece of card underneath) and take them back outside. connorbro 1 Quote Link to comment Share on other sites More sharing options...
DrKrettin Posted July 28, 2017 Report Share Posted July 28, 2017 Our local lizard (gallotia galloti) has males with beautiful big blue spots on their sides which have been shown to be more pronounced in ultra-violet. It seems reasonable to assume that this corresponds to their vision spectrum. Frustratingly, I don't know how to upload a photo I have of my favourite in the garden. Anyway, my guess is that for mating purposes, intensity of colour matters more than size. Quote Link to comment Share on other sites More sharing options...
connorbro Posted July 31, 2017 Report Share Posted July 31, 2017 That's a great information and observation. I would love to read more about that. Quote Link to comment Share on other sites More sharing options...
