The animal with the longest lifespan is the ocean quahog (Arctica islandica). This clam, found in the North Atlantic Ocean, can live for over 500 years.
Other Long-Lived Animals:
While the ocean quahog holds the record, other animals have impressive lifespans:
- Greenland shark: These sharks can live for over 400 years.
- Bowhead whale: These baleen whales can live for over 200 years.
- Galapagos giant tortoise: These tortoises can live for over 100 years.
- African grey parrot: These intelligent birds can live for over 50 years.
- Red sea urchin: These spiny invertebrates can live for over 100 years.
Factors Contributing to Long Lifespans:
Several factors contribute to the long lifespans of these animals:
- Slow metabolism: Many long-lived animals have slow metabolisms, which reduces the rate of cellular aging.
- Low body temperature: Cold-blooded animals, like the Greenland shark, have lower body temperatures, which can slow down aging processes.
- DNA repair mechanisms: Some animals have efficient DNA repair mechanisms, which help to prevent damage to their cells.
- Environmental factors: Factors like diet, habitat, and lack of predators can also influence lifespan.
