The Way Eye See It

This is just a random little project I started for no reason. I was collecting the inside stickers from printable CD labels, and got the idea to draw various different eyeballs from all sorts of creatures. How many do you recognize? (And don't feel bad if it's not many, I'm not the best eyeball drawer in the world.) See below for answers:)

Human, snow owl, pengiun, iguana, spider, snail, shark, horse, cuddle fish, chameleon, goat, cat, barn owl, alligator, Secretary bird, tarsier, dragonfly, shrimp, frog, wolf.
