Why is a dolphin a special mammal?
The blowhole on top of a dolphin’s head acts as a “nose,” making it easy for the dolphin to surface for air. Other characteristics of dolphins that make them mammals rather than fish are that they give birth to live young rather than laying eggs and they feed their young with milk.
What makes dolphins unique compared to other species?
Dolphins evolved from land mammals whose legs were underneath their bodies. As a result, dolphins tails move up and down as they swim, whereas a fish’s tail moves from side to side. Dolphins are warm-blooded and have blubber to keep them warm.
Why is a dolphin a mammal and not a shark?
