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

An endangered whale was spotted off Washington carrying her calf’s deceased body over a week after the baby was first documented by researchers. The baby Southern Resident killer whale was confirmed dead Dec. 31, the Center for Whale Research said in a Facebook post.

The research center confirmed J35 has been seen carrying the body of J61 with her. The CWR noted this behavior was seen previously by J35 in 2018 when she carried the body of her previous calf that had died for more than two weeks — 17 days.

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.

Two newborn calves joined the Northwest's endangered orcas in December. By New Year’s Eve, one of them was dead and being carried around on its mother’s nose.

An orca who carried her dead calf for 17 days back in 2018 has faced another heartbreaking loss. Tahlequah, or J35 to researchers, touched the hearts of people around the world when she carried the calf’s corpse with her for more than two weeks in what experts have called a 'deep grieving process'.

The bereaved whale mother who made headlines when she heartbreakingly grieved her dead baby for more than two weeks has given birth to a new calf, scientists said.
