Fun facts about the swordfish

The ones Sammy likes best. She tells them in the game, too.

  1. The swordfish has a special heater near its eyes that keeps its eyes and brain warm in cold, deep water.

  2. A swordfish's eyes can be as big as a tennis ball, some of the biggest eyes of any fish!

  3. The swordfish's long, flat sword is really its top jaw, grown super long.

  4. A swordfish swings its sword from side to side to slash and stun its food, not to poke it.

  5. Baby swordfish have teeth and scales, but grown-up swordfish have none at all.

  6. Swordfish sometimes leap high out of the water, maybe to shake off little critters stuck to them.

  7. A baby swordfish hatches smaller than a grain of rice, but grows longer than a grown-up person.

  8. Swordfish dive deep into the dark sea during the day and swim up near the top at night.

Riddle

Can a friend guess it?

Read the clues to someone, one at a time, without saying the animal. How many clues do they need? Fewer is better, just like in the game.

  1. I live far out in the open sea, and I swim in the Adriatic Sea too.

  2. By day I dive deep into the dark sea, and at night I swim up near the top.

  3. I have a special heater near my eyes, and they can be as big as a tennis ball.

  4. When I was a baby I had teeth and scales, but now I have none at all.

  5. My top jaw grows into a long, flat blade that I swing to slash and stun my food.

Sammy might be thinking of a swordfish.

In Thought Zoo, Sammy picks an animal and you ask her yes-or-no questions to find it. You'll find the swordfish in the Croatia adventure.
