Description
The gray whale (Eschrichtius robustus), also known as the grey whale, is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of 14.9–15.2 m (49–50 ft), a weight of up to 41 to 45 tonnes (45 to 50 short tons; 40 to 44 long tons) and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age. One of the longest-living gray whales currently is a female, first sighted in 1977, and estimated to be 53–55 years old as of 2024.
