this body of freshwater in mexico is also home to marine life. I am confused... Only lake Baikal in Russia comes up.

Mexico is a half a world away from Russia.

This is probably the lake you need.

thank you...that makes a lot more sense than lake baikal!:)

You're welcome. I searched for Mexico lake marine life.

I understand your confusion. The reference to a body of freshwater in Mexico that is also home to marine life might be incorrect. As of my knowledge, there is no natural body of freshwater in Mexico that supports both freshwater and marine species.

However, it is possible that the information you came across is referring to an exception or a specific case. To further investigate, you might consider the following steps:

1. Double-check the accuracy of the information: Verify the reliability and credibility of the source that mentioned this body of freshwater. Make sure it is a reputable and up-to-date source.

2. Look for specific examples: If your research still suggests that there might be a freshwater body in Mexico with marine life, search for specific examples or case studies that provide more details. This could include searching for scientific research papers, articles, or reports specifically about this supposed body of freshwater.

3. Consider alternative possibilities: In some cases, there may be unique ecosystems or brackish water conditions where freshwater and marine life overlap. These could be areas affected by natural phenomena, such as underground connections to the ocean, or human interventions, such as artificially created ecosystems or dams that maintain a mix of freshwater and saltwater. Researching these possibilities might lead you to the correct information.

Remember that information can sometimes be inaccurate or misunderstood, even in reliable sources. If you are unable to find sufficient evidence supporting the existence of a particular body of freshwater in Mexico that also sustains marine life, it is possible that it was a mistake or a misinterpretation.
