Scientists have discovered that the Cuvier’s beaked whale has set a new deep diving record for mammals.
In 2003 and 2004, researchers traveled to the Canary Islands in the eastern North Atlantic to collect data on 10 whales by attaching electronic tags to their activity patterns. It was found that the Cuvier’s beaked whale can hold its breath for 85 minutes and dive to a depth of 1,900 meters, breaking the 1,200-meter deep diving record held by sperm whales.
The second ranked beaked whale can hold its breath for 57 minutes and dive to a depth of 1,250 meters. The current deep dive record for divers is about 600 meters. Researchers at the Woods Hole Oceanographic Institution say the two species of beaked whales dive deep for long periods of time to forage, and they are able to avoid “decompression sickness” because the front lungs break down when they descend to a depth of 1,000 meters. Instinct collapse prevents compressed oxygen from entering the bloodstream from the lungs.
