Many people believe that there are jellyfish in lake Michigan. But, the truth is that they are not found in the lake. Jellyfish are found in salt water bodies and freshwater bodies. Lake Michigan is a freshwater body and it has no salt water near it.
Jellyfish are not a common sight in Lake Michigan, but they have been spotted. In the 1800s, a jellyfish was found in Lake Michigan. The jellyfish was seen again in the 1980s and then again in the 2000s. Some people think that these sightings are due to human-caused climate change, while others think it is because of natural causes like changes in the water temperature.
