I'm trying to compile a concise list of animals (not bird or fish types) so we can have a 'database'. I'll add a new letter every few days, if you can all add onto the thread we should create a veritable zoo!
U
Uakari - Black, Red, White/Bald
Ulysses Butterfly
Umbrella Jellyfish
Upside Down Jellyfish
Urial
Uromastyx/Mali/Moroccan Spiny-Tailed Lizard
Urutu Snake
Utah Prairie Dog/Ground Squirrel
