The killer whale also suffers from menopause

Killer whales undergo menopause the same as in humans, and this trait can be evolved to improve their descendants' survival.

The killer whale is one of three animals that continue their longevity after cessation of reproduction, allowing the mother to spend time later to look after their children.

Scientists at the University of Exeter and York (England) analyzed data on birthdays and deaths, as well as details of genetic and social relations in two killer whale communities, which share dense Menopause spots with humans and navigator whales.

'Our goal is to find out why these giant whales apply the same menopausal strategy as humans,' according to the Guardian, quoted by Exeter University expert Darren Croft.

Killer whales stop breeding at age 30, 40 but live until 90 years old.

This unusual whale's social structure may be the cause of this evolutionary trait.

Whales, whether male or female, live with their mother until the mother whale dies. The male whale also continued to return to the maternal side after pairing with female whales in other families.

Therefore, menopause can help the mother whale put all her strength into caring for her children and grandchildren, and avoid competing with her children.

Due to longevity, the killer killer whale also serves as a leader for about 40 family groups, and shares the experience of hunting for young whales.
