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

Wat eet dit?
It feeds mainly on zooplankton, ctenophores, other jellies and sometimes crustaceans. It uses its stinging tentacles to immobilise prey, then moves the food into its gastrovascular cavity, a body cavity used for digestion.1

Hoe om dit te herken

  • 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

Word dikwels verwar met: 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

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

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

Wat doen dit as dit bang is?

When touched, its tentacles fire venom-coated stinging filaments that stun or deter a perceived predator.1

As dit steek

  • Misting vinegar over the affected area can neutralise the sting. This stops unfired stinging cells from firing and adding to the discomfort.1
  • Klim uit die water en pluk enige tentakels af (met handskoene of 'n lap).
  • Vir tropiese kubuskwalle: gooi vir minstens 30 sekondes asyn oor die steke, roep hulp en wees gereed om KPR te doen. Vir bloublasies en die meeste ander: spoel af met seewater, dan warm water vir die pyn.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

  • Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
  • Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
  • As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

1

Its body has no excretory or respiratory organs.1

2

Its stinging cells can also entangle or anchor prey, not only inject venom.1

3

Sea turtles, ocean sunfish and larger jellyfish are its main natural predators.1

4

It has a free-swimming stage and a polyp stage, and each reproduces in a different way.1

5

Its body is radially symmetrical, with a single mouth at the centre of one end.1

Mite-breker

Mite: The Atlantic sea nettle lives in the Atlantic and other oceans around the world.

Waarheid: Earlier reports from other oceans were often mistaken, because this jellyfish was confused with other Chrysaora species. It is known from the Atlantic coast of the United States.1
