One of the characteristics most distinctive of fish, but at the same time one of the most deadly for these animals, is that they do not have the ability to breathe out of water, a situation that if prolonged can quickly lead to an agonizing death. However, there is a fish that can not only be fout of the water, but also does it for up to three hours, something impressive. Do you have any idea what species it is?
The biologist Heinz Arno Drawert was the person who found this new species of fish in Bolivia, which he had seen 30 years ago and which he recently saw again during a walk and which, according to the expert, is a new species of killifish gender seasonal Moema (Cyprinodontiformes: Rivulidae) from the PiraĆ river basin, southwest of the Amazon basin.
In addition to his physical and appearance characteristics that are visible to the naked eye, one of his qualities and strengths is his ability to survive out of water for a period of between two and three hours a day, something that according to the environmental engineer also breaks the schemes that people know about traditional fish.
During an interview with Mongabay Latam, Heinz Arno Drawert explained how this fishwhere it can be found, among other curious facts that make this species very special and apparently unique.
These are the characteristics of this fish that survives up to three hours out of water
In the talk that the researcher had with said medium, he mentioned the characteristics of this new species Seasonal Killifish of the genus Moema that can be out of the water for up to three hours.
He explained that this fish it has a pattern of lines that form a C on its body, with a light blue dot followed by a red dot, its fins are uniform in color, it does not have a black spot on the side that usually distinguishes the species to which it belongs and can stick to tree leaves.
The species discovered in Bolivia by the associate researcher of the Noel Kempff Mercado Natural History Museum, in Bolivia, this fish It is usually very territorial, so when the dominant male approaches the rest, both females and other males jump out of the water in order to avoid being attacked, an action that can be considered not only as a characteristic of the species, but also also as a defense and protection mechanism from its predator.
According to the biologist, the Rivulidae have amphibious characteristics, which allows them to breathe out of water. They also inhabit bodies of water that tend to dry up quickly, their eggs can survive droughts, not to mention their rapid sexual development.
This fish can measure between 15 and 20 centimeters, species that can be found in tropical regions, but not in cold or temperate zones.
Despite being precise in pointing out that this fish It is not an amphibian, the researcher also commented that this quality allows it to move easily towards other puddles. Regarding its reproduction, the specialist said that this species can reproduce itself.
About what would be the greatest risk to which a fish Rivulidae, pointed out that the destruction of their habitat is the most dangerous for this species, as are the effects of climate change.
