This name is appropriate because, apart from the lack of salt, this lake is very much like the sea complete with waves, archipelagos of islands and sharks. Despite being a freshwater lake, Lake Nicaragua contains sharks that have adapted to freshwater life.
The theory for the presence of these sharks was that over a period of time, the gap closed forming a lake and trapping the sharks which then adapted as the water as it gradually changed from saline to fresh.
