Whale Longevity
Recent research reveals that Southern right whales can live beyond 100 years, with some reaching 150, while North Atlantic right whales face an average lifespan of only 22 years due to human-induced threats like fishing gear entanglement and ship strikes. Using survivorship curves and photographic identification, scientists determined these lifespans. Long-lived species like bowhead whales can exceed 200 years. Understanding whale lifespans aids conservation strategies, given their slow reproductive rates. Future studies aim to assess the long-term recovery of whale populations impacted by historical whaling, with full age structure restoration expected to take a century.
