The Oldest Living Vertebrate on Earth 🦈

本站添加: 2026-04-30

The Greenland shark is the longest-living vertebrate known to science, with lifespans estimated at up to 400 years, meaning some individuals alive today may have been born in the 1600s; these deep-sea giants grow incredibly slowly at about 1 centimeter per year and do not reach maturity until over 100 years old, living in the freezing Arctic Ocean at a completely different pace than life on land.
