More than 70 percent of the planet covered by water. Three-quarters of the oceans have a depth of over 800 meters. Here begins the realm of the infinite sea depths beyond our reach.
This unknown world is 90 percent of the habitable space of the planet. We know more about the surface of the moon than about the sea floor. In this eternal darkness, inhabited by strange life forms. Only a few decades ago it was thought that life at these depths is impossible, but today scientists believe that the first life appeared on the bottom of the ocean. Energy, resources, food and even the climate is influenced by oceans. There to decide the future of our planet?
Only with the help of latest technology it is possible to comprehend the mysteries of the deep sea. Deep research is long and expensive, so so slowly, the scientists shed light into the darkness. Costly expeditions to the most modern vessels ply the seas in search of answers. Continue reading
The content of the fish in a saltwater aquarium can be very challenging. Maintenance of the necessary salinity of the water and a sufficiently high oxygen level in it even in a well – equipped aquarium is not easy. Most marine fish bred in aquariums, is habitat, so these fish cannot tolerate fluctuations. Reef the oxygen level is always high and a lot of light, because the corals grow only in shallow and clean water.
Sea water is very corrosive, so the aquarium must be made entirely of glass or plastic, without metal parts. Although marine fish are less inclined to jump out of the vessel compared to freshwater, the aquarium must be carefully closed to avoid contamination. It will also help to control evaporation: when water evaporates, salinity increases, so the vessel should be topped up with distilled water. Continue reading
In recent years, studies of the deep sea are very active. However, the oceans keep so many secrets that I reveal have scientists of several generations. There is evidence that to date 99% of the area of the bottom of the oceans of the Earth remain unexplored. However, there are animals, scientists are already open. And most of them boggles the imagination as to their appearance and lifestyle. A large part of deep-sea animals are predators. So, bathysaurus that live in tropical seas, is the predator who has mastered the very deep part of the sea.
He is able to swallow everything that gets in his way. His sharp tongue equipped with teeth, does not give the prey the slightest chance to escape. Bathysaurus not necessary friend of life: nature gave him the genitals of male and female at once. Long and sharp fangs has a fish-Viper. Your teeth that do not fit in the mouth, it is able to kill any prey, but can eat fish larger than themselves: her stomach is stretched if necessary. Continue reading
