Tame Silver Foxes are the results of nearly 50 years of experiments in Russia to domesticate the silver fox. Notably, the foxes did not only become more tame, but more dog-like as well: the new foxes lost their distinctive musky "fox smell", became more friendly with humans, put their ears down (like dogs), wagged their tails when happy and began to vocalize and bark like domesticated dogs.

Unlike Rays and other 'flat' fish that are flat in the sense that they lay on their 'stomach', with their 'back' to the surface, flounder are flat in that they lay on one side with the other side up. In other fish this would mean that one eye faces up, while the other eye is in the mud. Flounder are born like this, with an eye on each side of their head. One eye later migrates to the other side of the body so that both eyes are facing up.
