Beaked whales are known for their diving capabilities, but it's only now that it has been revealed that how remarkable their skill is. A Cuvier's beaked whale has set a new deep-sea diving record by diving two miles into the Pacific Ocean.

The dive was noticed during a study in which diving behaviours and locations of eight Ziphius off the Southern California coast were studied for periods of three months between 2010 and 2012.

The paper titled, 'First Long-Term Behavioral Records from Cuvier's Beaked Whales (Ziphius cavirostris) Reveal Record-Breaking Dives' has been able to collect 3,732 hours of dive data and dives of 9,816 feet and lasting 137.5 minutes.

"One key adaptation that seems to allow beaked whales to dive more deeply than other species is a dramatic reduction in air spaces within their bodies", said Erin Falcone from the Cascadia Research Collective in Washington State.

Experts said the record is absolutely spectacular. Water pressure two miles under water is 4,707 pound per square inch and it is equal to 320 atmospheres. It is the presence of air spaces in the body that would crush humans in such depths. Decline in air spaces not only makes whales 'crush resistant', but also reduce the consumption of dissolved gases into their tissues.

Another factor that works in the favor of Cuvier's beaked whales is that they need less recovery time when they come on surface between dives. It is said that they take an average of less than two minutes. Resaerchers are now studying the whale's behaviour in response to the military activity in southern California.
