Dolphins and all whales need air to breathe because they are mammals with lungs, not fish with gills. they are believed to have evolved as land animals and then returned to the sea.
yes, unlike fish and sharks they don't have gills. they are like whales and have blowholes. they jump out of the water and open their blowholes to get air before gravity works.
The reason dolphins live in water but breathe air is because GOD made them that way.
They have adapted by having fins to swim with.
Dolphins are air breathing mammals, just like us. They do not have gills to get oxygen, so they must surface to breathe through their blow holes.
They need them to breathe through. Dolphins, being mammals, have to inhale air and hold their breath underwater.
all mammals need air to live. This is the same with the dolphin.
Whenever dolphins need to get air they temporarily swim at the surface of the water. Baby Dolphins when born are pulled up to the surface so they don't drown.
Well they need air to breath they can't stay in the water without air they will die.
all dolphins are mammals because of why any other mammal is a mammal because they have live birth and need to breathe air to live.
Dolphins are mammals. They breathe air.
Pink dolphins need water because they are dolphins.
Whales, dolphins, dugongs. turtles, seals, walruses, etc.
Dolphins go to the surface because they need air (oxygen) to breath and fish can air (oxygen) from the water.
Yes, dolphins are mammals and have to come up periodically to breathe air.
They can spin with about 40-50 spinner dolphins in the air
Because the need to check out the other dolphins.
