**New York, NY (January 9, 2025)** – A groundbreaking study published in *Science Advances* has revealed that the lifespans of several whale species are significantly longer than previously estimated. Researchers using decades of photographic data and analysis of whale remains have determined that southern right whales can live well past 100 years, with some potentially reaching 150 – nearly double the previously accepted lifespan.

This contrasts sharply with the North Atlantic right whale, a critically endangered species closely related to the southern right whale. The study found their average lifespan is a mere 22 years, rarely exceeding 50, attributed primarily to human-caused mortality from fishing gear entanglement and ship strikes. This stark difference highlights the devastating impact of human activity on whale populations.

The findings build upon earlier research showing bowhead whales can live over 200 years. This new data suggests that extremely long lifespans are not unique to bowheads but are potentially characteristic of other baleen whale species, including blue, fin, sei, humpback, gray, and sperm whales. While current estimates for these species place their lifespans around 80-90 years, the researchers believe these figures are likely underestimates due to the decimation of older whales during the era of industrial whaling.

The study emphasizes the crucial implications of these long lifespans for conservation efforts. Whales with such extended lifespans reproduce slowly, making them particularly vulnerable to threats. Conservation strategies must account for these long lifecycles to be effective, particularly given the looming threat of climate change.

The researchers predict it could take another century for whale populations to fully recover to pre-whaling levels, even for species whose numbers are currently rebounding. The study serves as a stark reminder of the lasting impact of human activities on wildlife and the urgency of implementing robust conservation measures.
