There is a fish that lives on ... trees

Because of 'living' life, larvae fish can temporarily change their biological structure to adapt to life on the branches. Instead of soaking in water, this particular fish . breathes air and hunts continuously for months.

With the scientific name Rivulus marmoratus Poey , larvae hunting fish parasites on mangrove stems have been awarded the title of the most exotic fish that humans have ever known. In addition to being able to live on trees, Poey fish also has another " natural" ability to lay babies without mating.

This extraordinary capable fish was discovered by biologists on a field trip through the swamps in Belize and Florida - where they found hundreds of long-spotted fish by burning fingers in the branches. and rotten tree trunk. Inside the stalks, they lie in tandem along the ' trails ' that the insects have previously chiseled.

Anyway, living in a tree is not as comfortable as in a lake, if not extremely suffocating and crowded. Poey fish, known for its clear territorial division - must have tried very hard to contain the wrath.

An equally important question is, how did the fish transform their body's metabolism and structure to adapt to the new environment?

According to an analysis from researchers, bringing Poey fish has been ' upgraded ' to concurrently function as a water and nutrient holder, the remaining wastes will be excreted through the skin. More specifically, this change is only temporary. The natural structure is returned to its original form after the fish return to the water environment.

Previously, Poey fish was famous for being the only vertebrate that could reproduce without a partner. In other words, they develop both male and female genitals, which are responsible for fertilizing eggs right inside your body.

In terms of the ability to breathe air, Poey also has another 'ally' that is a walking catfish in Southeast Asia - its bearing allows breathing underwater and on land.

And the Indian perch is going to suffocate if you don't regularly throw yourself out of the water to get the air.
