A team of scientists from the University of St. Andrews in Scotland has used a new eavesdropping technique to record the vocalizations of little-known beaked whales in the North Atlantic Ocean. The results, published in the journal Current Biology, revealed that these whales can dive to depths of up to 2,992 feet (912 meters), making them the deepest diving mammals ever recorded.

"This is a really exciting discovery," said study lead author Dr. Peter Tyack. "Beaked whales are incredibly elusive, and we know very little about them. This new technique is allowing us to eavesdrop on their conversations and learn more about their behavior."

Beaked whales are a group of 22 species of whales that are found in all oceans. They are typically deep-diving predators that feed on squid and fish. Beaked whales are known for their long, slender bodies and distinctive beaks.

The scientists used a hydrophone array, which is a series of underwater microphones, to record the vocalizations of beaked whales in the North Atlantic Ocean. The hydrophone array was deployed near the Mid-Atlantic Ridge, where beaked whales are known to congregate.

The scientists recorded the vocalizations of beaked whales over a period of several months. They were able to identify the vocalizations of four different species of beaked whales, including the Sowerby's beaked whale, the True's beaked whale, the Blainville's beaked whale, and the Gervais' beaked whale.

The scientists also used the vocalizations of the beaked whales to track their movements. They found that the whales were diving to depths of up to 2,992 feet (912 meters). This is deeper than any other mammal has ever been recorded diving.

The scientists believe that the beaked whales are diving to such depths to feed on squid and fish. Squid and fish are abundant in the deep ocean, and the beaked whales are able to use their echolocation to find them.

The scientists' findings provide new insights into the behavior of beaked whales. This information will help scientists to better understand the ecology of these elusive animals.
