A recent study proposes that female killer whale menopause is followed by them taking up roles of the pod leader. It has been observed that they assist other whales of the pod to endure survival, particularly in times of hardship by steering them in the right direction in search of food.
Therefore, these female killer whales with their active leadership of the pod lead a long and fruitful life prior to their routine of conceiving babies. Their period of reproduction takes place between ages of 14 to 40, although it is usual for them to survive with a healthy life till the age of 90. The makes on the other hand, rarely can survive till 50. This recent study was published in the journal Current Biology.
The only three kinds of female species to survive even decades after menopause are us humans, short-finned pilot whales and the mighty killer whales. Study signifies the female killer whales take on the leadership position of the pod as they are no longer busy with bearing children.
Authors of the study have stated that “The value gained from the wisdom of elders can help explain why female resident killer whales and humans continue to live long after they have stopped reproducing.”
Marine mammal researchers belonging from the University of Exeter have studied the behavior of 102 killer whales surviving in the wild. The 751 hours of video captured over the duration of 9 years was assessed by the team of researchers. It was clear from the study that the older female whales were more probable to take on leadership in the cluster of whales and direct its team for the hunt of Chinook salmon, their primary source of food. The study reports “Leadership by post reproductive-aged females is especially prominent in difficult years when salmon abundance is low. This finding is critical because salmon abundance drives both mortality and reproductive success.”
