The Fish Quiz is an educational game based on the best scientific knowledge for about 300 species of marine and freshwater fishes. Have fun choosing the right environment, size, food, sex, and home for the fish in the photo. True fish sounds comment your choice. Learn as you play. Fish enthusiasts may score 50% correct answers, whereas fish experts will score 75% or more. You can explore the underlying information with the scientific database, and you can send us a comment if for example you think that the whale shark is a top predator instead of a plankton feeder. The Fish Quiz is part of the FishBase information system (www.fishbase.org) and the income from this App is used to support the continuous updating and improvement of FishBase.
