Tahlequah captured national attention after losing a baby under tragic circumstances in 2018. Now, researchers believe the mama whale lost another child.

A killer whale mom, who shot to fame after she carried her dead calf's corpse along with her for more than two weeks in a harrowing tale of grief, has suffered yet another devastating loss, scientists said.

A female orca who previously carried her deceased calf, has lost another baby shortly after birth. Scientists expressed concern for the calf's health. With two of her four calves lost, the situation raises worries for the future of the critically endangered orca population.
