If you ever really looked a great blue heron in the eye and watched him hit a pinfish swimming in ankle deep water you have no problem believing the velocoraptor is a bird's great grandpappy.
We really don't have that many poisonous snakes. The most common around my house is the black racer. I go get them out of people's screen rooms all the time. You can just grab them since they don't really have much in the way of teeth. I usually give them a finger to bite and grab them with the other hand.
Those down under folks can scare me with snake stories. They have the nasty ones.
