BetterZooa

The underwater world is teeming with relatives—some close, some separated by hundreds of millions of years!

BetterZooa challenges how well you know the fishy branches of life’s family tree.

You’ll try to guess the Mystery Fish in as few tries as possible. Every wrong guess teaches you something: wrong guesses will narrow down the answer by taxonomic rank. The closer your guess, the clearer the picture becomes. Dive deep, think smart, and trace your way through evolution—one fish at a time.
