Why can Greenland sharks live so long?

Greenland sharks live a long life because their lifestyle is slow.

The life span of Greenland sharks is between 272-5 12 years old, and the growth rate is very slow, only about one centimeter a year. It is not until 156 years old that they begin to breed the next generation. Mature Greenland sharks can be more than 500 cm long and swim quite slowly.

Extended data:

The eyes of Greenland sharks are indeed parasitic with copepods, which will eat the cornea of Greenland sharks, destroy corneal tissue and make the eyes partially blind. Of course, not all Greenland sharks have this problem.

Greenland sharks can feel the presence of light in the dark. Copepoda, a serious species in sharks, is a yellowish-white creature. It can emit its own bioluminescence. Although copepods can make sharks' eyes real names, their own light will become bait for sharks to prey.
