Cuvier’s beaked whales, also known as goose-beaked whales, can grow to be 23 feet (7 meters) long, and can weigh up to 6,800 lbs (3,080 kilograms).

They spend 90% of their time under the water, at depths or in shallower dives. When the whales do come up for a rare breath, they surface for around 2 minutes on average before diving again, leaving marine scientists little time to spot the whales.

Previously, in 2014, another team of researchers reported a record-breaking Cuvier’s beaked whale dive that lasted 2 hours and 17.5 minutes. However, when the new study’s authors examined data from 2017, they discovered a pair of extreme dives performed by one whale that obliterated the existing record. The first dive lasted 2 hours and 53 minutes, and that new record was quickly surpassed by an even longer dive of 3 hours and 42 minutes, according to the study. – Tiny Fox Lab
