Archeologists hold to an opinion that thousands of years ago the lake used to be a bay, but after dozens of volcanic eruptions the refuse stone formed a neck of land. Thus the part of the sea became a lake that with the passing of time became fresh because of running into rivers. Over the years the bull sharks got accustomed and became freshwater ones. Scholars are still arguing if it is possible to single them out as a separate species.

The locals say the sharks appeared in Managua because of the Indians who are believed to have made a sacrifice on the shore of the Caribbean Sea and thus sharks were drawn here and farther along San Juan River. So in such way they got into Managua.
Besides them there are a lot of other unusual predatory fish including saw-fish and sword-fish, lizards, for example, jesus lizards that can walk on water on their hindpaws. But still beaches around here are never empty. The locals are not afraid and feel free to come into the water and swim.
Within the bounds of the lake there are 300 islands and islets. The most popular among them is Ometepe island that was formed of two volcanos.
