Abstract

Human imagination has always been intrigued with the sea and its mysterious depths and the organisms. In the 19th century biologists considered that because of the pressure, temperature and light intensity deep-sea has no life. By the end of the 19th century thanks to the Challenger expedition (1872-1876) begins exploration of the deep-sea. In 20th century technology development allowed scientists to explore deep-sea. Deep-sea shows low diversity of species and biomass, but its habitants and its biological features are found to be very interesting. Thousand meters below the surface hydrostatic pressure is 100 times bigger so animals, which are indeed bizarre and fearsome looking creatures, are well adjusted to the deep-sea conditions. On the grounds of this paper and its subject I can conclude that the sea is an extremely rich habitat made of diverse community of flora and fauna which have develop numerous adaptations to survive. Evolutionary process of certain species is still going on. As long as there are life and living organisms they will be subjected to evolution and will be forced to adjust the new conditions and habitants. Never the less there is still a lot of secrets laying beneath the sea surface. A lot of organisms are still unrevealed, a lot of habitats undiscovered and incredible to humans. Great depths and the organisms, with their adaptations, living in them are still a mystery for we have only began to discover that world but those discoveries showed that deep waters are full of secrets and mysteries yet to be discovered.
