What is StickKleback?

Stickleback is a type of barbed fish found in the northern hemisphere. Sticklebacks are part of the Gasterosteus genus and include eight different types, all distinguished by different number of rear spines. StickKleBacks are often studied by evolutionary biologists because of the speed they develop. Most species have large eyes, square tails, and instead of a scale of bony plates cover their bodies. Colors vary between species. During mating, however, men change color and become shades bright yellow to black. StickKleBacks usually live for one to three years. In spring, men build nests using plants and excretion from their kidneys. Then they swim in the samples near the nest to attract a friend.

As soon as it was attracted, the woman was placed in her nest, then the man fertilizes eggs. After fertilization, the male remains in the nest that monitors eggs and aerates the eggs until they hatch and over the hatch. This behavior is seen in all kinds of Stickleback except white. Large fish, birds and some mammals such as otterY, prey to StickKlebacks. Although people do not eat these fish, they can use them for oil, fertilizer and animal feed.

Sticklebacks live in salt and fresh water. Their ancestors originally lived in an open ocean, but many species have since moved to lakes and rivers and adapted to the freshwater environment. The three -month market is one of the most common freshwater fish found in Britain. This is also common in other areas of Europe, the United States and Asia.

Evolutionary biologists study StickKleback because of its ability to quickly develop in a new environment and some ten years to make noticeable changes. The study of these fish is compared with Finches Charles Darwin on Galapagos Islands. Many freshwater sticklebacks have lost some or all bony plates and abdominal spine present on their sea ancestors. These boards and spine were necessary for protection in seawater but in SLAdoval environments were difficult feeding and maneuvering. The basic coloring of the sticklebacks is also lightweight to help ensure camouflage in a new sweet environment.

There is evidence that StickKleBacks shares several genes such as skin color, with other animals, including humans. Scientists believe that the study of the evolution of the StickleBacks can lead to information about the evolutionary process of man. As a result, extensive research is still being carried out on the development of StickleBack.
