Until tempers cool about sharks Bay Sharm El Sheikh, I would like to remind that there in the Red sea is not less dangerous inhabitants. Will tell you about some of them:
Jerzy. If the people of Japan it is a real delicacy, it is possible for tourists on the Red sea, thanks to their sharp needles, the trouble is a real one. In shallow water there is a big risk to step on them. So always watch your step, if the bottom is not sandy. Sea urchins inhabit the coastal waters, often settling there in the cavities of the rocks. Reach a length of 35 centimeters (depending on the species).
If You stepped on a hedgehog, the first thing you need to remove the needle from the body. Doctors advise to clean the wound with hot water or drop into her injured body. Then clean the wound with warm water and soap and apply an anesthetic ointment. The prick hedgehogs in extreme cases lead to paralysis or even death. Continue reading
Typical representatives of the nekton is the herring. It is well known that this fish has great commercial value. Until comparatively recently, it was promyshlyali in such large quantities that its price was very low, despite excellent taste and nutritional quality. In recent years, due to the sharp increase of the fishing fleet and introduction of intensive methods of production occurred overfishing. The number of herring in the oceans have decreased dramatically.
If in the future the intensity of the herring fishery will increase or even remain at current levels in the coming years, this valuable food fish will become a Museum rarity. Reduction of stocks of herring and concerned consumers and fishermen, but the first sounded the alarm scientists.

Species differences are not only in the details of the structure and the size of the fish, much deeper than they differ from each other in biology, numbers, distribution. Therefore, the fishery for mackerel fishes should be strictly subordinated to scientific data, to each type needs special approach. Continue reading
Sponges that are sold in stores and are used for washing dishes or cleaning the kitchen, not real. They are made from synthetic materials, although very similar to a real sponge and easy to use.
But these sponges appear in the sea, not in a chemical laboratory. For a long time many were convinced that they know all about sponges. It was believed that this plant, until in 1825 a man by the name of Robert Grant proved that sponges were animals!
It considered the sponge in water through a microscope. And saw trickles of water, which went in through one hole and out through another. Still, for many years, scientists did not know what kind of animal. Thought it was a tiny single-celled creatures that live together in one big colony.
We now know that sponges are the dried skeletons of marine animals belonging to the class of “porous”. This is a pretty significant group of animals. Although sponges are one of the lowest forms in the animal Kingdom, their structure is quite complicated. Continue reading
