I am curious... play if you want!
My second favorite is the octopus- it comes in so many forms, can immitate other animals both in color and mimicry, and they seem intelligent yet we know so little about them. Their mystery intrigues me.
My third favorite would be the elephant- their ability to have emotions is amazing and so is their familial structure.
Others I like just for beauty- polar bear, tigers, penguins, hummingbirds....
