Each one is a hyperlink too so clicking on them will give you all the info you're likely to need on them - locations, rank, school, recipes used in, rarity, aquariums, XP rewarded, sell price range, sizes etc...it even gives the fun descriptions of them that we get in our tome once we catch one
There are a few different ways to sort the list as well eg rank, rarity, world, school and aquarium size.
