World's Oldest Killer Whale J2, aka 'Granny,' Presumed Dead

World's Oldest Killer Whale J2, aka 'Granny,' Presumed Dead

Researchers estimate that J2 could be as old as 105, which would make her the oldest known killer whale on Earth.

The center said Granny was last seen on October 12, 2016, as she swam north ahead of others in her clan.

Granny, who was officially designated "J2" by scientists who studied her and her pod, is believed to be over a century old, born around the time when the Titanic was built.

"It was inevitable that this day was going to come but it is very sad news and a further blow to this population", Darren Croft, an evolutionary biologist from the University of Exeter in the United Kingdom who has studied Granny and other older female orcas, told BBC News. The orcas, including Granny, have been the subject of a four-decades long study from the Center for Whale Research in Friday Harbor, Wash.

Granny was the matriarch of her pod.

Granny was recognizable by a small nick on her dorsal fin.

Like humans, only two other mammals are known to experience menopause because they live long past their reproductive years - orcas and short-finned pilot whales.

Dr Balcomb said he last saw the whale on 12 October, 2016, when she swam north far ahead of the others. "And in recent years her world has changed dramatically with dwindling salmon stocks and increases in shipping threatening the survival of this incredible population".

The Center for Whale Research has announced that J2 has not been spotted with the southern resident Puget Sound J pod recently and thus presumes that she has died.

When he first began documenting Granny and her familiy in that year, he saw that the mature female was nearly always travelling with a mature bull.

"Perhaps other dedicated whale-watchers have seen her since then", he said.

"This mature bull was know as J1 or 'Ruffles" due to the waves in the trailing edge of his dorsal fin, ' Mr Pidcock explained.
