In an intriguing parallel to human biology, females of whale species which experience menopause have evolved extended lifespans, enabling them to support their offspring for longer, according to research by the University of Exeter, the University of York and the Centre for Whale Research.

The study focused on five whale species known to experience menopause. Menopausal female whales tend to live about 40 years longer than males of the same species, giving them extra years to care for their young and grandchildren.

Their groundbreaking study, published in 2022, marks a significant milestone in understanding and preserving vital marine ecosystems that are crucial for mitigating climate change.

The enactment of the Small Passenger Vessel Act (SPVA) in 2022 amended US maritime law, affecting the liability of small passenger vessel owners for safety violations that lead to accidents.

Orcas have long been considered a single global species, with different forms in different regions, known as “ecotypes.”

However, scientists have long recognised the differences between resident and transient orcas, known as Bigg's killer whales, in the North Pacific. Resident orcas maintain close-knit family pods and prey on salmon and other marine fish, while Bigg’s orcas roam in smaller groups and hunt other marine mammals such as seals and whales.
