BLACK sea and its inhabitants: who is dangerous to humans?

Fortunately, the really dangerous creatures, meeting with which threatens people severe poisoning, injury or even death, in the Black sea no. But still, one should be wary of some of its inhabitants. For example, in shallow water there is often found kornerot jellyfish (Rhizostoma pulmo), which has a characteristic dense “dome”. Its stinging cells, located at the mouth of the blades under the dome is quite scorching.

Another major black sea jellyfish – Aurelia, (long-eared jellyfish) many people believe is absolutely safe because of its stinging cells, located on the edges of the dome, much weaker than kornerot, and can not penetrate the skin. However, if a person touches the jellyfish, and then, without washing hands, you RUB your eyes or touch the lips, the tongue, the sensation will be very unpleasant. Although the black sea jellyfish is immeasurably less dangerous than, for example, the infamous “Portuguese ship” (“sea wasp”), it is better not to approach them and, especially, not to touch.
