It is quite an exception in the world of the fish. A group of scientists has discovered the Opah fish also known as moon, the first warm-blooded fish, sailing through the waters of Australia and the US, among other countries.

This fish species is more typical characteristics of animals and birds, as shown in research scientific. The Opah produces heat by moving their fins, and has developed an internal system “heat exchange” in their gills to maintain the temperature of your body and accelerate your metabolism.

Thus, body temperature remains stable at around 4 ° C and 5 ° C, with a more similar to that used for mammals and birds, which maintain their body temperature regardless of the environment in which they are system. The internal structure could help scientists discover how to hold the fish in the profundidaes living, of 50 meters underwater at night and 200 during the day.
These movements fish height should, say the . researchers to hunt for food that perform similar migration

This system also gives it an advantage over its ‘competitors’: while fish navigate the deep where lives the Opah are usually slower, the constant movement of this fish makes you more quickly. The scientists made their discovery by monitoring the temperature of the animal and check that was stable at different heights.
