Tahlequah

A mother killer whale who famously pushed the body of her dead newborn for 17 days in 2018 has lost another calf, and researchers say she is again carrying the body in an apparent act of grief.

The southern resident killer whale known as Tahlequah captured global sympathy in 2018 when she pushed the body of her dead calf for more than two weeks in waters off British Columbia's south coast.
