Which mammal holds its breath in water for 120 minutes?

Some mammals live in water. These are various whales and dolphins. They can hold their breath for a long time. Bottlenose whales can stay under water for about two hours (120 minutes). They have such abilities due to the structural features of the respiratory system, the need for air, and also due to the ability to experience hypoxia. A person can stay in water holding their breath for a very short time – about 2 minutes. Even with long training sessions and developed lungs, it will not be possible to hold your breath for more than 5 minutes.
