Interesting fact: Gray whales undertake one of the longest annual migrations of any mammal, traveling up to 20,000 kilometers round-trip.
The answer: Adult gray whales typically weigh between 30,000 and 40,000 kilograms (66,000 to 88,000 pounds).
Gray whales are large baleen whales found primarily in the North Pacific Ocean. They can grow up to 15 meters (49 feet) long. Their weight varies with age and sex, but adults usually weigh between 30 and 40 metric tons. These whales are known for their distinctive mottled gray coloration and rough skin patches caused by parasites. Their substantial weight supports their long migrations between feeding grounds in the Arctic and breeding lagoons in Mexico.
