Y know who has blue blood? It's not royalty—it's shrimp!

I recently found out that shrimp have blue blood, and I was totally amazed! It’s all because of hemocyanin, a protein that helps transport oxygen in their bodies, much like hemoglobin does for us, but it’s blue instead of red. I had no idea that something as simple as blood could be so different in the animal world. It made me think about all the other weird and fascinating things in nature that we don’t often hear about. For example, did you know that octopuses have three hearts, or that some species of frogs can freeze themselves during winter and thaw out alive in spring? The animal kingdom is full of surprises! What’s the most interesting or bizarre animal fact you know? I’d love to hear your thoughts!
