Questions & Answers

Q: Why do bats use both sight and echolocation?

Bats use both sight and echolocation to navigate as echolocation works for short distances, and visual cues are essential for long-distance travel.

Q: What do ostriches do when it looks like they have their heads in the sand?

Ostriches actually dig nests when it looks like they are burying their heads, with male ostriches building nests up to two to three feet deep.

Q: Why is urine not recommended for jellyfish stings?

Urine makes jellyfish stings hurt more, as the venom from the jellyfish's tentacles reacts negatively with urine, causing more pain. Vinegar is suggested for relief.

Q: How do chameleons change colors?

Chameleons change colors by adjusting their chromatophores and using a nano crystal guanine lattice triggered by neurotransmitter signals, for various reasons including stress and mating.
