Quais cuidados devemos tomar ao encontrarmos uma água-viva (medusa)?

It is generally best not to touch jellyfish washed up on the beach, and particularly not in the water. Remember that the stinging tentacles can be far from the main body of the Jellyfish, so be aware of this when swimming near them, or walking barefoot along the sand. When diving in water where jellies are likely to be encountered, it is best to wear at least a rash guard and a thin hood to reduce exposed skin.

Em qual ambiente vivem as esponjas? E os cnidários?

O que podemos fazer se formos queimados por uma a água-viva?

First aid frequently depends upon the type of Jellyfish and the severity of the sting. The first step is to get the victim out of the water. If there is severe allergic reaction, call 911 (or the equivalent emergence service) immediately. Rinse the sting area with seawater or warm water (in some places, it is recommended to use vinegar, and some even suggest urine, but for some types of jellyfish, vinegar or fresh water can reactivate the stinging cells, making the matter worse). There are also commercially available sprays and liquids designed for treatment of Jellyfish stings. Once the wound has been rinsed to stop further stinging and remove the nematocysts, it can be soaked in warm water, or covered with an ice pack, and treated for pain with commercial topical pain relievers.
