Creator description · original textText language: English
The Greenland shark is the longest-living vertebrate on Earth, with a lifespan capable of reaching centuries. This video explores a fascinating biological paradox: despite exhibiting severe cellular hallmarks of aging, including massive cardiac fibrosis, extreme lipofuscin (age pigment) accumulation, and heavy oxidative stress, the shark's heart remains perfectly healthy and functional. Discover how this elusive deep-sea giant relies on extraordinary physiological resilience rather than resistance to aging, allowing it to sustain a beating heart for hundreds of years.
