"Greenland Sharks' Slow Metabolism Key to Longevity"
Greenland sharks, known for their extraordinary lifespans of up to 400 years, may owe their longevity to a slow and stable metabolic rate. Research by Ewan Camplisson suggests that unlike most animals, these sharks do not experience significant changes in metabolic enzyme activity as they age. Understanding these mechanisms could provide insights into human aging and health, although the complexity of aging means much more research is needed.
