Why do frogs croak at night?
Show answer & explanation
Answer: Males attract females
To scare predators — Wrong. Croaking would attract predators, not scare them. Many predators hunt frogs by sound.
Males attract females ✓ — Correct! Male frogs croak to attract females during breeding season. Each species has a unique call so females find the right mates. Nighttime is safer for calling when many visual predators are inactive!
Night air helps their voice — Wrong. Night air doesn't affect frog voices. They call at night because it's safer from daytime predators.
