Along the edges of the ditches strange dark mounds appear that from a distance have the appearance of oddly-shaped rocks. When approached, however, these peculiar heaps turn out to be composed of groups of Caspian turtles (Mauremys caspica), which, like other reptiles, are sometimes referred to as “cold blooded” because their level of activity is dependent on the ambient temperature. To operate effectively, these turtles must raise their body temperature and this is why they emerge from the cold water to sunbathe for long hours. In springtime tiny baby turtles can be seen practicing their swimming skills.
Not far away catfish are making waves. In springtime, when they suddenly remember that they, too, need to be fruitful and multiply, they perform courtship dances in the shallow water beside the banks. Their companions, the tilapia, make do with digging holes for the eggs they will lay.
