A Giant Blind Fish Appears in Meghalaya, India – It Will Refresh Your Cognition
In our impression, cavefish are generally small individuals, belonging to small fish.
This is due to the growth environment of cavefish. Cavefish typically grow in dark rivers or caves without sunlight.
These places are perpetually dark, with no sunlight, which limits the growth of algae due to the lack of photosynthesis.
Even if algae can grow, the plants are relatively small, relying on fewer bottom-dwelling organisms that grow from algae, and fallen leaves cannot reach underground dark rivers.
These reasons lead to a scarcity of food in underground dark rivers, and the fish in the water adapt to the environment in order to survive.
Therefore, the body of the fish is also relatively small, with little food, in order to survive, it can only shrink its size.
Impression: Cavefish individuals are very small
According to the report of 'Hebei Youth Daily': In the Megalaya region of India, there is a place called Chintia Ridge. A research team came to the nearby mountain cave, and they accidentally discovered a giant cavefish in the underground water pool inside.
However, this giant cavefish was no less than 30 cm long, surpassing all its peers. Scientists once thought that the underground water environment in the cave did not have conditions to produce large fish, firstly, the lack of light is not conducive to foraging, secondly, the scarcity of food. However, the existence of this giant cavefish undoubtedly overturned the traditional scientific cognition.

Cavefish are distributed widely in the world, with discoveries in America, Europe, Africa, and Asia.
The first discovery was in 1842, when it was recorded in the United States as a sedentary cavefish – cave loach.
Since 1976, China has reported the capture of a cavefish in the caves of Kunming, Yunnan, and new cavefish have been discovered one after another.
Why are cavefish called cavefish? Because they have been living in underground caves for a long time, their eyes have degenerated, and other
Sensory organshave developed particularly well.Cavefish's newly hatched larvae have eyes, and when these larvae grow to about 2 months old, their eyes gradually degenerate.
Although cavefish have no eyes, they will not hit other objects when swimming on the bottom of the water.

and cavefish have strong hunting abilities, they can find tiny static food on the bottom of the water.
Although they live in completely dark caves, they can use their body's line sense to distinguish directions and hunt for food.
Cavefish is an omnivorous fish with a tendency to carnivorous, and it has a gentle temperament and likes to swim in groups.
The color of the cavefish's body is white or pink, which is very different from the color of ordinary fish.
The body length of the cavefish is generally about 10 cm, and occasionally large individuals are found, but they are rare. This time the discovery of a giant cavefish in India may be a new subject for the scientific community.
