Pretend a gorilla and a otter meet in river country. Look at the facts. Then you pick.

Would they meet?

Almost never. Their homes sit next to each other.

This is pretend and based on facts. Real animals usually hide or leave.

Read the facts. Make your card. The page waits to pick.

THE SCIENCE PICK

Gorilla!

A STOMP

You skipped a final pick. The facts still stamp a champ.

On river country, Gorilla wins. Gorilla is a lot heavier. Otter would still win some meetings at home.

In the wild, most animals skip a fight. We still judge who the bodies and the place would favor.

Science card: Gorilla 7 · Otter 1.

Your card: Gorilla 0 · Otter 0.

The last page follows the whole animal — body plus home — not one bar chart.

Send this fight

A friend can read the same facts.

Victory lap · Gorilla

Five seconds of gorilla. Blink and you miss the champ.
