Abstract
There are a lot of weird and wonderful adaptations across the Animal Kingdom, and none more so than animals that have adapted to extreme environments, such as caves. Not only are caves dark, but they can be nutrient poor and low in oxygen, making it a challenging environment. Despite this, almost 300 species of cavefishes from around the world are currently known and characterized by their pale bodies and lack of eyes. These fishes have adapted their whole biology from molecular cell biology to physiology and behaviors, meaning that almost every type of biologist can learn something interesting from cavefishes.
