#video | the worms, without mouth and digestive system eat most unexpected way

Every living organism needs food intake, but in the world there are creatures that have no mouth or digestive system. For example, these include paracetemol flat worms that live on the seabed in regions with a temperate climate. Not being able to directly consume nutrients, these creatures manage to live in peace for over 500 million years. And the secret is that inside they are full of bacteria Riegeria that secrete essential for life organic compounds.

Bacteria inhabit the bodies of the worms, called trophosome, and fills almost the entire cavity of their bodies. The worms themselves are transparent, but it is these organs bacteria give them a white color. The bacteria are chemosynthetic, that is for energy use is not the color of the sun, and chemical reactions. In particular, we are talking about the reaction of carbon dioxide and hydrogen sulfide, which synthesizes lipids, proteins, sugars, fatty acids and vitamins.

Over thousands of years, bacteria Riegeria so simplified its genome that now they perform the most important functions only. Marine microbiologist Harald Gruber-Vodicka said that they had never seen such a symbiosis when bacteria from is so simplified genome produces so many nutrients.

In these symbioses, the host almost digested inside the bacteria. However, this is not the case — the micro-organisms themselves secrete the body needs substance in the form of tiny droplets. Because of this, they always remain intact, and this symbiosis can be considered perfect and winning like flat worms and microbes.

Regarding worms is another interesting material — recently a group of researchers from the University of Michigan found that the roundworms have a substance that prevents aging.
