So in class, we were asked to add adaptations to our animal and I was wondering if adding goo (a colorless layer, like sweat but thicker) would make an animal fly faster?

Answer :

Answer:

Not necessarily.

Explanation:

The texture of an animal's skin isn't necessarily going to help it fly. Flight consists of aerodynamics and assests like wings, a fanned tail, and/or a pointed figure, like a bird possesses.  Adding this slime/goo that you mentioned will not add to it's aerodynamics, meaning that the answer would be no.

If you give the animal a lighter frame as in bones then they would be lighter and fly easier.
