The Christmas tree hydroid is a small, branching sea creature that grows in colonies on rocks and hard surfaces in shallow water. It is found in warm seas around the world, and it is common in the Mediterranean Sea. Scientists have used it to study how animals catch their prey.1

Contact with a rope on which this hydroid was growing caused an acute, painful skin inflammation (dermatitis) in several people. Contact with the stinging cells on its tentacles is the cause.1

Ndi yoopsa bwanji kwa anthu?

Ngozi kwa anthu: YopwetekaIngathe kupweteka kwambiri, koma pafupifupi nthawi zonse si vuto lalikulu.

Several people who touched a rope covered in this hydroid got an acute, painful dermatitis. No deaths are known.1

Ikalasa

  • Tuluka m'madzi ndipo chotsa minyewa yolasa (tentacles) iliyonse (ndi magolovesi kapena nsalu).
  • Pa jellyfish ya bokosi (box jellyfish) ya kumadera otentha: thira viniga pamene walasidwa kwa masekondi 30 osachepera, itana thandizo ndipo ukhale wokonzeka kuchita CPR. Pa bluebottle ndi zina zambiri: tsuka ndi madzi a m'nyanja, kenako madzi otentha kuti uchepetse kupweteka.

Nthawi zonse yamba wayimbira nambala yadzidzidzi (112, 000, 911). Awa ndi malangizo wamba a chithandizo choyamba, osati malangizo a dokotala. Zoyambira za chithandizo choyamba

Khala wotetezeka

  • Usakhudze, kugwira kapena kuseweretsa nyama yakuthengo, ngakhale yaing'ono, ndipo ngakhale ikuoneka ngati yagona kapena yafa.
  • Ipatse malo. Ukakumana nayo, khala chete, bwerera m'mbuyo pang'onopang'ono ndipo uilole ipite njira yake.
  • Ikakulasa: khala chete, usasunthe, imbira nambala yadzidzidzi (112, 000, 911) kapena pita kuchipatala mwachangu. Kumbukira m'mene inkaonekera, chithunzi chimathandiza.

Sikufuna kukuvulaza. Imagwiritsa ntchito ululu wake kugwira chakudya kapena kudziteteza, ndipo imakonda kwambiri kubisala. Zambiri za kukhala wotetezeka
