Can My Goldfish See In Colour?
December 15th, 2011 by admin
YES!! Goldfish can see colour better than humans! Many thanks to all of those that attended the fantastic lectures by Professor Ron Douglas from City University London. A big thank you to Colour Group GB for sponsoring Ron to come down and deliver the lectures.
Kestrels prey on well camouflaged Field mice, but unfortunately for the Field mouse, Kestrels can see in UV. Urine reflects UV so a Kestrel can spot a Field mouse from its urine trail!
How fast does a light have to flash before it is seen as continuous? If a light is flickering above 60 times a second (60Hz) then humans can’t tell but a chicken can see up to 105 flashes a second and a fly or a bee can see up to 300Hz!
Question: Out of the following animals which see no colour? Dog, bull, frog, bee, squid, cat or do all of them see no colour?
Answer: Squid see no colour!
Once again thanks to Professor Ron Douglas for delivering the lectures and a special thanks to the Colour Group GB for sponsoring Ron to come and deliver the lectures for us.
