The beauty of the underwater world of the ocean / relaxation and enjoyment

Our planet is 70% water, most of the water component is oceans and
seas. The underwater world is a special world filled with marine
microorganisms, fish and other inhabitants. There are many dangers for
a person, because he is not expected there, so you need to follow the
most important rule at the bottom - do not touch anything there. The
most dangerous marine animals can live anywhere, but most of them are
concentrated on the ocean floor. It is worth fearing not only large
creatures, but also small ones who know how to defend themselves no
worse than toothy predators, and the weapon for this is poison.
