I once hit a 14 point buck in my 1980 Mercury Zephyr. It rolled over twice, tried to get up, fell down, tried again and ran way. The biggest dear I've ever seen. Team Zephyr just needed a new radiator though.
I hit a doe in a 1993 Honda Civic Hatchback, but due to the radiator being so small and only on one side, I escaped with a lost bumper and crumpled hood. Four months later I was driving home from work, and there were 5 deer spread across the two lane highway. So...I knew my car was done either way, so I sped up to 75 and well that deer went for a long flight through the air.
Never hit a bird, hit an opossum once though. Pretty sure I've run over a snake or two.
I once saw a turtle crossing the highway, so I pulled over to go help him out, and as I was getting out of my car a diesel ford toughing a motorboat crushed the little guy. :(
