Why is the Blind Cave Fish named Fish?

The "Blind Cave Fish" is not its official name. It's a common name used for several different species of fish that have adapted to live in caves. These fish have evolved to lose their sight and often have other adaptations, like heightened senses of touch and smell, to navigate their environment.

Here's why they are called "fish":

* They are fish: These creatures are members of the class Actinopterygii (ray-finned fishes). They have the same basic physical characteristics as other fish, like gills, fins, and scales.

* It's a descriptive term: "Blind Cave Fish" is a descriptive name that tells you something about the fish's habitat (caves) and its most notable feature (lack of sight).

It's like calling a bird a "migratory bird" or a mammal a "sea mammal." The name describes a characteristic or behavior rather than being a scientific name.

Scientific names are more precise: Each species of cave fish has a scientific name, such as *Astyanax mexicanus* for the Mexican tetra, which is a common cave fish species.
