Sea turtle, Fernando de Noronha, Brazil  Jun 16, 2025

They"ve got built-in helmets, a slow-and-steady vibe and zero interest in your deadlines. Sea turtles, like this one photographed in Fernando de Noronha, Brazil, have been cruising Earth"s oceans since before T-rex was a thing. There are seven species of sea turtles: green, loggerhead, hawksbill, leatherback, Kemp"s ridley, olive ridley and flatback. Among them, the leatherback sea turtle is the largest, sometimes reaching almost 2 metres in length and weighing between 300 to 640 kilograms. Each species has unique behaviours, diets and nesting patterns—yet all share a deep connection to coastal and marine environments. Let"s protect these ancient mariners—for the oceans, and for the future.
