Photographer's Note

Continuing with the series of images caught in my visit to the Ecological Reserve Costanera Sur, I tried during kilometers of long walk, to portray a turtle aquatic without success, given the distance in which they were and the foliage that hid them.

In a while, I found in the edge of the embankment that borders the access roads a turtle totally ready "to model". Of there this image that it wanted to share with you.

In Argentina, the turtle of lagoon - Phrynops hilarii- has ample distribution in the tie region with the water bodies of the river basins of the Parana rivers and Uruguay, arriving by the south until the northern sector of the province from Buenos Aires. The species lives in addition in almost all Uruguay, the south of Brazil and great part of Paraguay.

They are excellent swimmer due to the modifications that in the course of the
evolution it has undergone its anatomy, equipped with a hydrodynamic design, since the shell - considerably smooth is tablet in its dorsal and ventral part. Also the extremities are flattened backwards; in addition they have membranes between the fingers that when extending they facilitate swimming.

The turtle of lagoon is carnivorous; it consumes alive and dead prey. The components of their diet varies in agreement with the age and the station of the year: the young they feed fundamentally with insects, snails and tadpoles; the adults consume insects, fish, pichones of birds and small mammals. Its main predators they are reptiles (like the yacare) and birds (like the storks), that eat eggs and youthful units. The size of the prey and its diet change as they grow, when also it increases his voracity.
