Atlantic sea nettle
The Atlantic sea nettle is a jellyfish that lives along the Atlantic coast of the United States. It has a bell-shaped body and stinging tentacles that it uses to catch food and to defend itself. Its sting is painful for people, but it is not strong enough to cause death except through an allergic reaction.1

Com reconèixer-lo
- Bell-shaped body that is usually semi-transparent1
- Small white dots and reddish-brown stripes on the bell1
- Typically pale, pinkish or yellowish, with deeper stripes near the edge of the bell1
- Bells without stripes look white or opaque1
- Smaller than the Pacific sea nettle1
Sovint es confon amb: It was often confused with several other Chrysaora species, so older reports of this jellyfish from other parts of the Atlantic and other oceans may be wrong. C. chesapeakei, found in estuaries on the Atlantic coast of the United States and in the Gulf of Mexico, was only recognised as a separate species in 2017. The Atlantic sea nettle is smaller than the Pacific sea nettle and has more variable colouring.1

Què fa el seu verí?
Each tentacle is covered in thousands of microscopic cells that fire venom-coated stinging filaments on contact. The venom can kill smaller prey or stun predators. In people, the sting most likely causes a painful but non-lethal rash that usually lasts about 20 minutes. Some earlier reported stings in the Philippines caused vascular insufficiency (poor blood flow) and mononeuritis (inflammation of a nerve).1
Com de perillós és per a les persones?
Perill per a les persones: DolorósPot fer molt de mal, però gairebé mai no és greu.Its sting is rated from moderate to severe. It is not potent enough to cause human death, except through an allergic reaction. While the sting is not particularly harmful, it can cause moderate discomfort.1
Què fa quan té por?
When touched, its tentacles fire venom-coated stinging filaments that stun or deter a perceived predator.1
Si pica
- Misting vinegar over the affected area can neutralise the sting. This stops unfired stinging cells from firing and adding to the discomfort.1
- Surt de l'aigua i treu els tentacles que quedin (amb guants o un drap).
- Per a les cubomeduses tropicals: tira vinagre sobre les picades durant almenys 30 segons, demana ajuda i prepara't per fer RCP. Per a les caravel·les portugueses i la majoria de les altres: esbandeix amb aigua de mar i després amb aigua calenta per al dolor.

Estigues segur
- No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
- Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
- Si te'n pica un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.
