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

Anaishi
Warm tropical and subtropical Pacific, Atlantic and Indian oceans, Mediterranean Sea and eastern Arabian Sea1
Bahari ya Pasifiki, Bahari ya Atlantiki, Bahari ya Hindi, Bahari ya Karibi, Bahari ya Timor na Arafura, Ghuba ya Bengal
Nyumbani
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
Urefu

Kasi ya juu
takriban km 0.36 kwa saa (maili 0.22 kwa saa)
Kuogelea, makadirio
Hula nini?
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

Jinsi ya kumtambua

  • 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

Mara nyingi huchanganywa na: 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

Nguvu ya sumu

Mikono inayodunga

Maelfu ya seli ndogo za kudunga hufyatuka kitu kikizigusa.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Hatari kwa watu: HafifuKama kudungwa na nyuki au chini ya hapo. Kimsingi hana madhara kwa watu.

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

Akidunga

  • Toka majini na uondoe vipande vya mikono iliyonata (kwa glavu au kitambaa).
  • Kwa yavuyavu sanduku wa kitropiki: mimina siki kwenye sehemu zilizodungwa kwa angalau sekunde 30, omba msaada na uwe tayari kufanya CPR. Kwa mabotoli ya bluu na wengine wengi: suuza kwa maji ya bahari, kisha maji ya moto kupunguza maumivu.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

  • Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
  • Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
  • Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

1

Each apparent individual is actually a colony of hydrozoan polyps, not a single animal.1

2

Young Malabar trevally fish shelter under the floats and panic when removed from them.1

3

Young Malabar trevally fish appear to prefer a particular colony and will return to their own partner when separated and put back in the same tank.1

4

It is preyed on by sea slugs known as blue dragons and by violet sea-snails of the genus Janthina.1

5

The blue button has a single mouth under its float, which it uses for both eating and removing waste.1

Kuvunja dhana potofu

Dhana potofu: A blue button is a single jellyfish-like animal.

Ukweli: Each blue button is a colony of hydrozoan polyps, which are related to anemones, corals and jellyfish.1
