today i learned – weds 17th oct 2018

this fact genuinely blew my mind 😱 hopefully it will yours too 😏

#tdil that iguanas have three eyes 😱 … no, they legit do 🦎

how mad is that?! 😱 now, before you go telling me that you’ve seen an iguana and it definitely didn’t have three eyes … i can assure you that they do 😅

you see, the third eye isn’t actually an eye that looks the same as the other two 👍🏻 instead, it’s a special eye that is simply there to sense changes in light ☀️

it can’t create any form of image, as it’s just a rudimentary retina and lens … but it’s hella important because it helps protect the lizard from aerial attack! 🦅

wondering where you can see the mystery third eye? just look for the opalescent grey spot on top of their heads 😁

how awesome is that?! what an epic bit of evolutionary goodness 😎

laters! 😃 #tdil


it feels weird to have an actually informative fact on here for once 😂 fancy something else? just take a look ->here<-

(images! the header is ->here<- and the other is ->here<-)
