Question 8
Which animal is known for the longest lifespan among vertebrates, with some individuals living for centuries?
Correct answer: Greenland shark
Greenland sharks are exceptionally long-lived vertebrates; scientific estimates suggest some may live for several centuries. The estimates are based on radiocarbon dating of proteins in their eye lenses, so individual ages are uncertain.
