Read our privacy policy Dolphins and other toothed whales like orcas use a Kim Kardashian and Katy Perry-like “creaky voice” to catch prey in the deep, said a new study. Researchers found the toothed whales particularly use the vocal fry register to produce their echolocation calls to reflected sound and catch prey. “During vocal fry, the vocal folds are only open for a very short time, and therefore it takes very little breathing air to use this register,” Dr Elemans said. While this creaky voice register may be considered “annoying” or “authoritative” in humans, the vocal fry has helped toothed whales become an evolutionary success story.
