Fan Fact of the Day -Tortoises and crocodiles are seemingly immune from biological aging – a phenomenon known as negligible senescence or biological immortality.
Unlike humans, who continue to age after reaching maturity – caused by a gradual accumulation of cellular damage, tortoises, can continue to reproduce at very old ages and show few signs of functional decline as they get older. Instead, they tend to die due to disease or predators.
Bonus fact – the world’s oldest recorded non-colonial animal (like corals and moss), was a 507-year-old ocean quahog clam named Ming, that was unfortunately killed by the researchers that found it while determining its age.
