Question

Dolphins and whales have gills to breathe in water.

• A. True
• B. False

Answer 1

The correct option is B False

Dolphins and whales do not breath with gills like other aquatic species. They belong to mammals and have to come to the top of the water to breathe air through blowholes which are present at their top of heads. They have lungs which other aquatic species do not have.

So the correct answer is 'False'.
