• Animals on a cold prairie in winter huddle to decrease heat loss.

• Bees swarming in a hive raise the temperature inside the hive.

• Dogs pant and sweat through their tongues.

• Elephants lack sweat glands, but they wet down their thick skins with water and flap their ears, which are rich in capillaries.

• Humans shiver and jump around to keep warm.

Clarifying Terms

1. Cold-blooded and warm-blooded are not scientific terms.

2. Ectotherm means heated from outside and is probably closest in meaning to cold-blooded.
