Tumblr Thread: Dragon Evolution And Binocular Vs. Monocular Vision


A flamethrower is by no means a precision weapon. This fun Tumblr thread considers why dragons would have eyes on the sides of their heads. It sounds like it could be because they place the greatest value in the field of view (when considering other predators) over depth perception.

Vertebrate - ll youSee 4G e 20.41 O 59 % 4 galahadwilder A sudden, terrifying thought When you see an animal with its eyes set to the front, like wolves, or humans, that's usually a predator animal.

Bovine - If you see an animal with its eyes set farther back, though-to the side-that animal is prey. Now look at this dragon.

Dragon - They're to the SIDE. O Nicolás Pera - Amisigaudi This raises an interesting-and terrifying- question.

Text - perfectly-generic-blog The eyes-in-the-front thing (usually) only applies to mammals. Crocodiles, arguably the inspiration for dragons, have eyes that look to the sides despite being a predator. pyrrhiccomedy hey what up l'm about to be That Asshole This isn't a mammalian thing. When people talk about 'eyes on the front' or 'eyes on the side, they're really talking about binocular vision vs monocular vision. Binocular vision is more advantageous for predators because it's what gives you d

Text - (The eyes-in-front = predator / eyes-on-sides %3D %3D prey thing holds true far more regularly for birds than it does for mammals. Consider owls, hawks, and falcons vs parrots, sparrows, and doves.) But it's not like binocular vision is inherently "better" than monocular vision. It's a trade-off: you get better at leap-strike-kill, but your field of vision is commensurately restricted, meaning you see less stuff. Sometimes, the evolutionary benefit of binocular vision just doesn't outweig

Text - For example, if you are a crocodile, there is a decent chance that a hippo will cruise up your shit and bite you in half. I'd say that makes monocular vision worthwhile. Which brings us back to OP's point. Why would dragon evolution favor field of view over depth perception? A lot of the stories l've read painted the biggest threats to dragons (until knights with little shiny sticks came along) as other dragons. Dragons fight each other, dragons have wars. And like fish, a dragon would ne

Text - Really, why would dragons have eyes on the front of their heads? Seems like they've got the right idea to me. rachelladytietjens Rebageling for the profoundity of “A flamethrower is not a precision weapon." 171.556 notes
