TED-Ed: Inside the killer whale matriarchy - Darren Croft

The video explores the social structure and survival strategies of Southern Resident killer whales, focusing on the vital role of grandmothers. These matriarchs lead their families, especially in hunting, and their evolutionary adaptations include menopause, which allows them to invest in their families rather than reproducing. The video highlights the critical need for conservation efforts due to declining salmon populations and suggests further research to understand other whale populations.
