Here's an awesome animal list (take it with a grain of wikipedia-salt, of course).
Did you know that if you want to say that someone is "alligator-like," you can call them "eusuchian"?
Or that a baby crocodile is called a "crocklet"? (Even better: a baby falcon is called an "eyass.")
Or that a group of earthworms is called a "sloop"?
Or that a group of siskins is called an "ebert"? Not to be confused with... (Okay, sorry, it's late.)
Or that the male and female armadillo is called a "lister" and a "zed," respectively?
(I'm picking these out more or less at random.)
Answer: this list is coming very handy in a song I am writing. Of course!
