The great lake of Nicaragua (Cocibolca) has a total length of 170 kilometres. It is dominated by two volcanoes: Momotombo, which has an altitude of 1400 metres, and another much smaller volcanic cone, Momotombito (389 metres), which can be seen in the centre of the picture. In the waters of this beautiful lake, a true wonder of nature, naturalists have found three species of fish, originally from the Pacific Ocean, which have been able to adapt to fresh water thanks to the high urea content in their blood. - 1977
