What is an interesting fact about trout?
What is an interesting fact about trout?
Trout is the common name for a number of species of freshwater fish. They are native to the Northern Hemisphere but have been widely introduced to other areas. Trout are distributed naturally throughout North America, northern Asia and Europe.
How long does a trout live?
How long do trout live? Based on scale readings, the general view is that trout will generally live for around 6 or 7 years, but this figure is highly variable. There is anecdotal and photographic evidence that some trout can live a great deal longer.
Do trout have teeth?
Large trout have strong jaws and can easily bite aggressively and draw blood. Smaller trout have teeth but usually small enough not to worry about. Unlike many species of fish, trout have vomerine teeth which grow on the roof of the upper jaw. These teeth are used to hold and move food down the throat of a trout.
How fast can a trout swim?
We estimated the overall average swim speed for Rainbow Trout to be 0.84 m/s (SE = 0.02), with a 95% confidence interval of 0.79–0.89 m/s, and that for Westslope Cutthroat Trout to be 0.84 m/s (SE = 0.03), with a 95% confidence interval of 0.78–0.90 m/s.
How do trout sleep?
The answer is yes, fish do sleep. Fish need rest just like humans and other animals, but the way in which fish catch their zzz’s is quite different from how most animals sleep. Some fish lie near or on the bottom when sleeping while other fish must constantly swim to push water over their gills to breathe.
Do trout have tongues?
Yes, most fish do have tongues, but they aren’t at all like ours. Most fish have a bony structure called the basihyal on the floor of the mouth that superficially resembles a tongue. But it doesn’t have taste buds, isn’t muscular and has very little range of motion, so it isn’t directly equivalent.
Can you lip a trout?
While it’s fine to lip some species of fish like bass, it is best to keep your fingers out of a trout’s mouth because it puts unnecessary stress on the fish, and because they have small teeth. Keep those hands on the body of the fish!
Do trout hibernate?
Trout and other stream fish prefer to spend winter in habitats with large deep pools and boulders and survive well under stationary ice. Backwaters and side channels are important for escaping surface ice, underwater ice dams, and anchor ice. Other fish move upstream into snow-blanketed tributary streams.

Can Fishes see in the dark?
Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.
Do fish play?
Biologists have documented fish playing with a bottom-weighted thermometer and other objects. Play, like much of animals’ psychology including emotions, motivations, perceptions and intellect, is part of their evolutionary history and not just random, meaningless behavior.
