because it is dark in a cave, good eye sight is not required.
The main idea is to explore and provide explanations for the evolutionary phenomenon of cave fish losing their eyesight. Researchers study this process to understand how environmental factors can drive changes in species over time, leading to the loss of unnecessary traits like eyes in dark cave environments.
The Blind Cave Fish is named the Blind Cave Fishbecause it has no eyes!
Fish do not have as good eyesight as us but they can still see up to one hundred metres long.
A fish someone killed by pulling out it's eyes. A Blind Fish, as in the Mexican Tetra, a blind cave fish.
Some of the most blind animals include moles, which have very poor eyesight and rely on their other senses to navigate underground. Other examples are cave-dwelling species like the Mexican tetra fish and certain species of cave-dwelling salamanders, which have evolved to live in complete darkness and have lost their eyesight over time. Additionally, some species of blind snakes, such as the brahminy blind snake, have adapted to a burrowing lifestyle, leading to their blindness. These adaptations highlight the diverse ways animals can thrive in environments where vision is less critical for survival.
The most important sense that a cave fish typically relies on is its lateral line system, which is a sensory organ that detects vibrations and changes in water pressure. Since cave fish often live in complete darkness, they have adapted to their environment by losing their eyesight and enhancing their ability to sense movement and navigate through their surroundings using this lateral line system. This adaptation allows them to effectively find food and avoid predators in the murky cave waters.

The Osteichthyes is evolved from lungs of early bony fish. The fish have many types of evolved.
Cave fish don't have eyes.
you can.go to maraqua and near the big hole in it has a cave go in the cave and you will find a pond you can fish there.
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
Because that is where fish evolved.
