About this game
In this game you see two animals and a question, for example which one is heavier. Tap the one you think wins, then see the real numbers for both.
The two values always differ by at least 25 percent, so the answer is never a coin flip. Each round has 10 questions about Sea animals. You will meet 48 animals, including Blue-ringed octopus, Dugong, Clownfish, and Giant clam. The questions ask about weight, length and how long they live.
The numbers are typical adult values and they are rounded. Real animals vary a lot.
