The blue button is a small sea creature that floats on the surface of warm oceans. It looks like a jellyfish, but it is really a colony of tiny animals called polyps. Its sting is not powerful, but it can cause slight skin irritation.1

Leef in
Warm tropical and subtropical Pacific, Atlantic and Indian oceans, Mediterranean Sea and eastern Arabian Sea1
Stille Oseaan, Atlantiese Oseaan, Indiese Oseaan, Karibiese See, Timorsee & Arafurasee, Baai van Bengale
Tuis
It lives on or near the surface of the sea and drifts with the currents and wind. Recent reports describe large numbers washing up along coastlines in Japan, and increases in the Ionian and Adriatic seas.1
Lengte

Wat eet dit?
It is a passive drifter, so it relies on currents and wind to bring food. It mainly feeds on copepods and crustacean larvae, and it can also hunt active crustaceans such as crabs and fish.1

Hoe om dit te herken

  • A round, almost flat, hard golden brown float about one inch (2.5 cm) wide1
  • Bright blue turquoise to yellow polyps hanging from the float1
  • Blue strands with knobs of stinging cells at the tips1
  • Looks similar to a jellyfish, but each 'individual' is a colony of polyps1

Word dikwels verwar met: It looks superficially like a jellyfish. It is related to Velella and to the Portuguese man o' war, which are also colonial animals that float on the surface.1

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

It has stinging cells called nematocysts at the tips of its tentacle-like strands. The sting is not powerful and may cause slight irritation to human skin.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

The sting is not powerful and may cause slight irritation. In recent years, the first recorded case of contact dermatitis (a skin rash caused by contact) from this species was reported in Japan.1

As dit steek

  • 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
