When you think about how animals sleep, you probably picture them lying down in a safe spot. Fish don’t really sleep the way land animals do, but they do rest. Sharks are a bit different from typical fish, and their resting behavior varies quite a bit from species to species. So do sharks sleep on … Read more
When you watch a shark glide through the water, it’s easy to wonder how it breathes. You see dolphins and whales coming up to the surface to breathe air, and you know fish extract oxygen from water somehow. Sharks are fish, but they’re also really different from the small fish you see in an aquarium. … Read more

If you’ve ever looked closely at pictures of whales, you might have noticed they’re often covered in weird white or grayish lumps. Those lumps are barnacles, small creatures that attach themselves to the whale’s skin and stay there for life. With some whales carrying hundreds or even thousands of barnacles, it raises a question: do … Read more
