They live exclusively in freshwater lakes and rivers and come in a wide variety of colors that change based on their environment, making them masters at camouflage. Preferring cool, clear streams and lakes, they can be found in waters averaging 10-16 degrees C (50-60 degrees F) so if you want to go diving with trout you better bring a thick wetsuit. Different species are native to North America, northern Asia, and Europe, and were introduced to Australia and New Zealand by fishing enthusiasts in the 19th century. The most commonly sighted species are the brown trout in Europe and the rainbow trout in both America and Asia. Not only are they exciting to see while diving, they are an important food source for humans and many animals such as bears and birds of prey.
