They have a diverse population worldwide and exist in different species all over the world. More passive acoustic work will be conducted, and they hope to do more tagging and eDNA sampling, improving their techniques over time.“We want to continue to introduce new technologies into the project to learn more about the distribution and ecology of the various species of beaked whales,” Cholewiak said. They have a diverse population worldwide and exist in different species all over the world. In the past, whalers have sought out the Sperm whale for the valuable spermaceti oil, which makes an extremely fine lubricant. The species was identified from a skull found on the Mediterranean coast of France. A part of their tooth protrudes from the gums and has a shape similar to the tip of a spade. Their large head makes up to 33% of their body length and mass. Cuvier’s beaked whales can dive for one hour at an approximate depth of 1,000 meters.
