Why do blue whales dive deep?
Whales are marine mammals that dive for various reasons, such as: feeding and mating. Their prey are found at varying depths under the water and depending on where in the water column that is, whales dive to various depths for varying periods of time. … As they dive down, pressure increases with increasing depth.
How deep do whales typically go?
Experts have suggested that this was an unusually deep dive for this species, and a more normal depth is 2,000 metres. All whales rely on coming to the surface of the water to breathe oxygen – so they must hold their breath for remarkably long periods of time.
Can a killer whale dive deeper than 1000 feet?
South Atlantic killer whales have destroyed their own record for deep dives—by 1,000 feet. Killer whales in the South Atlantic Ocean are willing to dive more than a thousand feet more than previously recorded—if they are certain to get a snack at the end of it, researchers have discovered.
Do whale lungs collapse?
Deep diving whales and seals have reinforced airways that allow the lungs to collapse during the dive, preventing damage. The collapse forces the air away from the alveoli (where the gas exchange between the lungs and blood occurs).
How long can a blue whale stay underwater during a dive?
Blue Whales can hold their breath for about 90 minutes, but typically do not exceed 30 minutes underwater at a time.
