This picture definitely wins the thread.
Since I moved to Texas, I've encountered a lot of creatures that I'd never seen in person before, some of them just hanging around my house.
The first pic is of an alligator devouring some kind of large frog. I ran into this guy at a local botanical garden, right on the sidewalk between the cafe and the theater. Some people have seen alligators in my neighborhood, too, although they're mostly smaller than this one.
