In most parts of the natural world, eyesight is key. Animals use it to find food, escape danger, and move around. But in some of the darkest places on Earth– like deep caves, underground tunnels, and certain underwater spots– evolution took a different route. Some animals lost their eyes over time. Others never had them at all. For these creatures, not being able to see isn’t a weakness– it’s just how they’ve adapted. In total darkness, vision doesn’t help much. So, instead, they rely on other senses, like touch, smell, vibrations, or chemical signals, to survive and find their way. Here are five incredible animals that live without eyes!
