This infographic compares the known mitochondrial adaptations that grant Ocean Quahogs their remarkable 100+ year lifespan, highlighting the mystery behind why some individuals achieve an extraordinary 500+ years.

Gill tissue has the lowest oxidative damage of any tissue, cardiac mitochondria show no decline even after 100+ years, and both keep ROS production minimal through modified electron transport. But here's what puzzles me: these adaptations explain why the species lives so long—not why some individual quahogs live 50 years while others reach 500.
