Also, like all mammals, dolphins even have a tiny amount of hair, right around the blowhole. Whales and porpoises are also mammals.
How does a dolphin give birth?
Dolphins give birth to a single baby; the baby is usually born tail first (unlike most mammals) to minimise the risk of drowning. The birth can take a couple of hours.
