SAN FRANCISCO (KGO) -- A drone captured rare video of two little gray whales swimming next to their mom in Southern California.
The twin babies and their mom were spotted by people on a whale-watching boat off Dana Point.
According to the boat captain, it's rare to see a gray whale with two calves. Usually there's just one baby.
He says this is something he has never seen before.
