Im making a comic and have 2 questions for reality factors?

Question

1) can reptiles see ultra violet light like dogs see only 1 color or maybe a species that hasent been discovered in caves yet see ultraviolet and see heat emited in a different color like floresent orenge?

2) if both your achilles tendons were severed would you fall forward or backward while peeing and could the stream go in the persons face?

Answer 1

Reptiles can see some colors on the electromagnetic spectrum of visible light, I dont think any such species has been discovered yet.

If you were peeing, and both achilles tendons were severed, the direction of your fall depends on your center of gravity.. If you are leaning back, you will fall backwards, in which case, the stream would go up and back down like a fountain, and if forward, the stream may reach the face area.

Interesting question, I had fun answering it lol.

Answer 2

Reptiles can see in the UV spectrum. I don't know about heat vision, that is the other end of the visible spectrum, infra red.

If your Archilles tendons are cut, your calf muscles become useless, so you would not be able to stop yourself falling forward, because these are the muscles that would contract.
