An endangered orca is carrying a dead calf around on her head in a tragic repeat of behavior that made headlines six years ago.
Tahlequah, or J35, became famous in 2018 for embarking on what some scientists described as a "grief" tour, pushing her dead calf through the ocean for 1,000 miles (1,600 kilometers) until she eventually let go. She went on to successfully rear two other calves. But now, Tahlequah, part of a struggling group called the southern resident killer whale population, appears to be grieving another calf.
