While researching this question, I went to a research facility called Pacuare Reserve, on a beach where many leatherback sea turtles go to nest. I got to participate in boots-on-the-ground conservation efforts, and see the incredible biodiversity in the area.
Unfortunately, I don't have any pictures of these turtles, as I only saw them at night and the flash would hurt their eyes. They can grow to be up to 6 feet long and have no natural predators except for sharks, but turtle populations are still shrinking dramatically. There are two main reasons for this. Firstly because the sex of the eggs is determined by the temperature of the sand, which is increasingly warm, resulting in an unbalanced population. The second threat to eggs is poaching from the impoverished nearby communities. Before the reserve was established, 98% of the eggs were poached. We patrolled the beaches at night and collected their eggs to keep them safe.

There were three types of monkeys at the reserve, including howler monkeys, whose roar sounds like a much larger animal.
