#30 Guess who's behind me?
Greenland sharks can live up to 500 years, and the U.S. National Oceanic Administration reports that these creatures have the longest lifespans of any vertebrate.
Greenlandic sharks have no fin spines and no hard tissue on their bodies, but they grow extremely slowly, less than 1 cm per year and can reach more than 6 m in size.
Scientists speculate that such long lifespans may be due in part to their extremely slow metabolism, which is able to withstand extremely cold waters.
These sharks do not reach sexual maturity until they are over 100 years old, so their juvenile life safety is particularly important, even though they are nearly 100 years old.
