Mammals: The Strangest Behaviors and Adaptations

Their blue blood comes from hemocyanin, which is better at transporting oxygen in cold environments.

In some shrimp species, the heart is located in the head because of their body structure.

Some tarantulas flick irritating hairs at predators to defend themselves.

25. Fireflies Produce Light Without Heat

Fireflies glow due to a chemical reaction called bioluminescence, which produces light without generating heat.
