About This Quiz

Were you aware that fishes are known to be the oldest aquatic vertebrates found around the world, having a fossil record spanning over 500 million years? Today, fishes can be found in an endless array of places: lakes, streams, rocky shores, reefs, kelp forests, ponds, oceans, estuaries and under sea ice, to name a few. When it comes to freshwater fish, there are thousands of different types. (Over 15,000, to be more precise.)

Freshwater fish species can vary greatly from country to country, not to mention from state to state. Their size, color, diet and even behavior help fishers and fish enthusiasts identify what type of fish they’re dealing with. Fish are unique and differ greatly from one to the other. Some of them you might know very well, especially if you go out fishing regularly or have an appetite for fish. But as you put the names of a few fish in your catch-and-eat bucket list (or perhaps just the eat bucket list), how well do you actually know your fish? Take this quiz and test your scales... I mean, skills.
