Blue whales are mammals. They breathe air with lungs, pretty much just like you and I. When they dive, they hold their breath.
A whale CAN drown- they cannot stay underwater indefinitely. When underwater, they hold their breath. They are REALLY good at holding their breath, and their bodies have adapted to doing that.
whales are the largest underwater animal.
Adult gray whales can stay underwater for approximately 10 - 15 minutes.
Whales cannot swim very far underwater just because they are too big. Whales can swim up to 3000 feet underwater.

Whales come up to "vent" every ten to fifteen minutes. A common myth is that whales can go hours without breathing air.

The blue whale can stay underwater for 20 minuties
Dolphins are not fish they are mammals or air breathing creatures that live underwater and come up for air like whales . ps.dolphins are part of the whale family
