Fish exist in almost all water bodies on earth and often play an important role in the life of both humans and the entire ecosystem. Fish, like people, are unique and this uniqueness lies both in the structure of the body and in behavior. Some like solitude, while others gather in flocks of up to several million individuals. Some fish are even able to climb tree trunks, while others can go without water for several days.
In addition, most scientists believe that all mammals are descended from fish, which makes them even more unique creatures.
We all know the size that sharks can reach and what bizarre shapes fish in tropical waters can be. But there are also very tiny fish, whose dimensions are calculated in millimeters.
Our rating today will tell you about the smallest fish in the world that are known to people. We present you the photos and names of baby record holders.
10 Stickleback, 50 mm
एक प्रकार की छोटी मछली grows up to a small five centimeters. A distinctive feature of this species is the presence of special, sharp fins, which the fish, in case of danger, uses as protection from predators.

In addition to the status of one of the smallest fish in the world, zebrafish is one of the fish that have left our planet. The fact is that this fish was taken with them to the orbit of our planet for scientific research.
The observation of the young is facilitated by the fact that the embryos develop outside the female and are distinguished by good health and endurance.
It would seem that the similarities between fish and humans are minimal, but this is not entirely true. Similarities still exist, especially in the structure of the cardiac apparatus. This makes it possible to conduct research in the development of certain drugs with the active participation of zebrafish.
The fish gained great popularity due to active breeding in the aquarium. This was facilitated by the fact that scientists modified the species by introducing a gene from mollusks into it, which allowed the fish to acquire a neon glow.
8. Formosa, 30 mm

This fish leads a generally very passive lifestyle and keeps to the bottom. Larger predators like to eat this fish. It is not a fishery at the moment.
4. Mistichthys, 12,5 mm
An amazing fish called mystihtis, is unique in that it is completely transparent. The habitat is the Philippine Islands, in addition, they also live in the waters of sea lagoons and among the waters of mangroves.
A distinctive feature of these fish is that they swim far into the open ocean to spawn. In addition, despite their small size, they are an integral part of the Philippine fisheries.
3. Goby pygmy pandaka, 11 mm
This fish lives off the coast of Southeast Asia and is famous for its tiny size. For aquarists, this crumb became known back in 1958, despite this, keeping it in captivity is a very difficult task.
This schooling fish, despite its size, is a craft for local residents. They make a snack out of it and eat it regularly.
Due to their small, almost imperceptible size, the study of this species is problematic. They hide almost all their lives on the seabed, under the protection of shells and various other natural shelters.
2. Pygmy goby, 9 mm
