Dangerous marine animals

The immeasurable diversity of nature on our planet: scientists consider to 3500 species of mammals and more than 850 000 species of insects. Despite the fact that already for many centuries is explored flora and fauna, and annually published reports of discoveries of new species, which find even in long inhabited and explored areas. So, in the early 30-ies of our century was known to 800 thousand species of butterflies, and by 1942 he already 900 thousand species. Even less studied is the life in the oceans, which often make sensational discoveries.

The existence in the seas and oceans are dangerous animals the people knew even in ancient times, although along with very real views were widespread tales of fantastic sea monsters. It was known about the danger of injections of some animals, on the toxicity of some marine animals by eating them for food and, of course, about large aggressive fish – the shark. Currently published a lot of papers devoted to the description of poisoning from the ingestion of marine animals in different parts of the World ocean. So, only in 50-ies of our century from such poisoning suffered tysjacheletij. According to the researchers, only poisonous fish there are about 500 species, most of which live in the salty waters.

By climatic and geographical basis distinguish polar, Northern, temperate, subtropical and tropical zones. The majority of our population lives in Northern and moderate climatic zones and therefore are not familiar with the fauna and flora of the tropics. Year-round abundance of warmth in them contributes to the rapid development of wildlife. So, in the Amazon region, has about 15 thousand different species of animals. Continue reading

Seaweed

Kelp – brown algae, which have long been eaten by the people who lived near the sea. The edibility differ only in some of its species: laminaria saccharina and palmately dissected laminaria. They are called sea cabbage. Information about its usefulness became widely known, which explains the popularity of this product. But despite this, around kelp considerable controversy supporters that believed in her neoteleostei, and opponents who believe that the damage to health caused by it doesn’t pay get the benefit.

After the extraction of dried cabbage, as it is 80% water, but during drying the product does not lose useful properties, fully preserving all the vitamins and minerals. In the process of manufacturing kelp is minimally processed, which also does not destroy valuable substances, does not lead to their loss or collapse due to exposure to temperature.

The composition of seaweed and the main areas of its application

Laminaria has an unusual smell that repels some consumers who prefer familiar foods and decide on questionable experiments. However, her continued presence in the diet in recommended doses equivalent to the use of nutritional Supplements, because the composition of seaweed rich in mineral substances: iodine, zinc, cobalt, magnesium, sulfur, iron, manganese, and vitamins A, E, C and B. It is the undisputed leader in the amount of iodine in the composition, 100 grams provide organizational the intake of iodine, and in this form it is not excreted, what happens when absorbing it from other sources. On the contrary, it absorbed better than advertised, and expensive drugs. Continue reading

Hammerhead sharks

Class – Cartilaginous fish / subclass – Plasminogene fish (Elasmobranchii) / Superorder Sharks (Selach)

History of the study

The history of the evolution of hammerhead sharks has been very successful. In our days it is one of the most common shark species in the world, and in some places they’re just going in astounding quantities. Hundreds of individuals run around seamounts.

Few other species of sharks form such large flocks. This is one of the greatest mysteries of the ocean. Why are so many of these sharks gathered in one place, at one time. Oddly enough, in these large schools the majority are female, and we don’t yet know why this happens.

Distribution

Widely distributed in tropical and temperate waters of all oceans, except, of course, the Arctic. Most commonly found in the Gulf of Mexico and Caribbean sea, near Hawaii, Philippines, New Zealand and many other seas of warm and temperate latitudes.

Hammerhead shark is truly one of the most unusual sharks. Her appearance seems truly alien, but it is quite common in tropical seas around the world.

When you look at the shark hammer head there is just one question – why this animal has this kind of pharmagology? What is it? And how it appeared? After all, nature creates freaks. And if it generates by mistake, they can not compete with “normal” types and die. All the more strange that there are many types of hammerhead sharks of all shapes and sizes, at least 9 different species. Surely nature could make so many mistakes and “give birth” so many freaks, well there are millions of years?! Continue reading
