The blind cavefish
The blind cavefish is an extodinary creature. It thrives in dark caves in southern Missouri, although it was originally from Mexico. It is only about 2 inches long, and is a pink-white color. Its diet includes blind crayfish, flatworms, copepods, and amphipods. Females lay around twenty eggs, and they need very little food to survive. It has two forms, and they are the blind cave fish form and the Mexican Tetra form. Their lifespan is about five to ten years. Some say they are vulnerable, and others think the species is endangered, so I am not sure which is true. A large threat to them is water pollution. They are very interesting creatures, so I hope you research and find even more about them!
