This is the world’s smallest fish, know its size


There are millions of species of creatures present on Earth. All living beings have their own nature and shape. But do you know which is the smallest fish in the world? Let us tell you that the size of this fish is equal to the nail of an adult human. Know where scientists have discovered this fish and what is its name. 

The world’s smallest fish

According to the report of The Guardian. Scientists from Berlin have spotted a unique fish in the rivers of Myanmar. The name of this fish is Danionella cerebrum. The size of this fish is only 12 millimeters and it appears completely transparent. But this small fish can make sounds louder than 140 decibels. If you compare this sound with gunshot, ambulance siren and jack hammer, then the sound of the fish will be louder.

Let us tell you that according to scientists, according to its size, it is the loudest ever found. It is a noisy fish. The loudest sound among aquatic creatures is considered to be that of pistol shrimp, which can make sounds up to about 200 decibels. It does this to scare the hunter.

The sound of the fish is loud

Scientists took this fish to Berlin and did research. . Verity Cook, lead author of the research published in the journal PNAS, said that the sound of Danionella cerebrum is so loud that if you pass near fish tanks, you may get scared after hearing the sound. This is extraordinary because these fish are very small and the sound is very loud. Most of the sound of fish is converted back into water. This is the reason why vibrations are seen in the water when these fish stand near the tanks. 

How do fish make sounds

According to Cook All bony fish have a swim bladder. A gas-filled organ that helps them stay under water. Many fish use their muscles to drum on this bladder to produce sound. But Danionella is different from these. When it contracts its muscles, it pulls the ribs. Due to which the muscle hits the bone. This sound comes from there. According to the information, both male and female fish of this species make sounds. But generally other female fishes do not make any sound.
