illions of years ago, life began to develop in the form of unicellular organisms on the bottom of the ocean. Later on, these primitive organisms evolved into marine creatures that gradually moved from water to dry land. They adapted themselves to the atmospheric conditions and went through a series of physiological changes. Finally, man evolved.
 

t can be concluded that man had aquatic origins but water was no longer his natural habitat. The new conditions had to be studied and “adjusted” to the human organism. From time immemorial, man has sought methods which would help him walk the “way back”. The development of technology and equipment greatly contributed to the realization of his dream. What attracted mankind to the world of silence was perhaps the inner feeling of relation to the ocean. With rich knowledge and sophisticated devices, he eventually managed not only to penetrate into the marine blues but also to “communicate” with the marvelous underwater life.
