Well, I have to be honest, my favorites are bigger, and mammals of the sea ~ I love dolphins, whales, seals and manatees. I know we won't have these creatures in our OK Aquarium (I hope), don't want to see them in captivity, but I do appreciate the work and wonder of the Aquarium. I DO love sea otters - what cuties!!! They are doing a good thing there and I applaud them. Would love to have the family pass! Thanks Tasha!
