Blue Whales Return
Critically endangered blue whales, the largest creatures ever known to have existed, are returning to Britain’s sub-Antarctic island of South Georgia.
U.K. scientists say the whales appear to be growing in numbers around the island after being nearly wiped out by whaling 50 years ago. While only a single blue whale was seen there between 1998 and 2018, 58 were spotted in a survey in February of this year.
Another recent study found that humpback whales are also returning to the same waters.
