Sea Creatures: Dolphin Trivia Quiz — Enjoyable Three-Choice Questions on Fun Facts

breathing hole

Dolphins breathe by inhaling air through a blowhole located on top of their heads. While swimming underwater, they keep the blowhole closed, and when they surface, they open it to take a quick breath. This allows them to exchange gases efficiently.

Make a sound from the forehead

Dolphins may appear to produce sounds from their mouths, but in fact they emit sound waves through a fatty mass in their head. This functions as an acoustic lens, focusing the sound waves and projecting them over long distances.

To make it easier to swim

Dolphins gather around ships because the waves and currents created by the vessel make it easier for them to swim. They use the wave generated at the bow as a form of “surfing,” allowing them to move efficiently, which is why they behave this way. People often perceive this as play, but in reality, it’s a clever strategy that helps them travel more easily.

bubble ring

The rings of water that dolphins blow from their mouths are called “bubble rings.” Dolphins use their tongues to create rings of air, and the way those rings float stably underwater is truly mysterious. You can often see them during dolphin show performances.

bait

Dolphins obtain moisture from their food and use the water contained in what they eat to maintain their internal fluid balance. Because they do not drink seawater or tap water as is, they tend to prefer foods with a high water content.
