Photo @materas // A gray whale shows its tail before a deep dive in Magdalena Bay, Baja California Sur, Mexico. Gray whales migrate to Magdalena Bay in the winter to mate and calve. The unique scars and markings on the tail are used to help biologists identify individual whales, which can reach sizes of up to nearly 50 feet and live for up to 70 years!
