Animals and humans can in crease the weight and more fat and take care of depednent intake of food consumed. 

However, what occurred in your head when there are animals whose body was shortened and elongated according to the season. There are fish that like you know it.

Rare phenomenon was the subject of researchers from Finland and Norway are the results of research published in the journal Functional Ecology. This is a resea rcher from the two countries, also the phenomenon of downsizing the first body was found in fish.

The researchers said the reduction took place during the winter. They describe, reduction or shrink age in body size was triggered by a condition called anroexia over the winter, a time when the fish ap petite dropped dramatically when the winter.

To arrive at these conclusions, the research team led by Ari Huusko from the Finnish Game and Fisheries Research Institute in Paltamo experimenting with salmonid groups, such as salmon and trout. The researchers create a pool of experiments that have been designed in such a way as to have conditions like winter in subtropical areas.

"We were faced with un expected facts and has never been documented before. Fish actually shrink in winter condition. Young salmon showed a significant reduction in body size, as much as 10 percent of the length of his body," the researchers said in its publications.

Re searchers do not know the exact biological mechanisms that lead to the downsizing of the body. However, researchers speculate that it is associated with diminished fluid, such as gel, contained in the spine which triggers the body size reduction. (HERMAWAN)
