Several things make of Barracuda Lake a special place. One is that here you can find sweet and salty waters. The top 4 meters are of sweet water, while the rest is salt water. Second, is that here waters are from warm to very warm (from 28 to 38 Celsius degrees). Third, is that here you can experience the thermo clines first hand. Fourth, is that the lake has its own fauna, including a solitary Barracuda (hence its name).
Unfortunately, I was unable to see the barracuda. All I could see where the crabs and the little fish in the picture.
