The Aleutian Islands form one of the most geologically active regions in North America. The island chain, which stretches westward from Alaska, is home to two dozen active volcanoes. And since the start of the 20th century, it’s been the epicenter for more than 30 earthquakes of magnitude 7.5 or stronger.

The hagfish is one of those animals that scientists aren’t quite sure how to classify. These bottom-feeders have a skull but no backbone. Like lampreys, they have no jaw, but then lampreys do have vertebrae. Hagfish look like eels, but with naked skin instead of scales. They can survive up to 36 hours without oxygen — while their hearts keep beating — and they’ve been around for more than 350 million years, long, long before the first dinosaurs ever walked the Earth.
