I believe my Patronus would be a dolphin. They are loyal to those who they do not know, like saving sailors from drowning, and they're gentle, sweet, kind creatures always ready to help. But they also have a protective, aggressive side, that will come out when a loved one is endangered, like a baby dolphin being circled by a shark. They stay together during life and when one dies they mourn for days. They are hunted by dolphin poachers, like in The Cove, but still they try to help parts of their pod.

I think this describes me pretty well. Loyal, kind, protective, and aggressive when they need to be.
