Wosafa modabwitsa Turritopsis nutricula

Posachedwapa, asayansi chidwi modabwitsa Turritopsis nutricula. Mofanana ndi kukopa tcheru kwambiri akatswiri, makamaka geneticists ngati zolengedwa yosavuta? Ndipo onse kutsegula lotsatira. A wasayansi ku Italy Fernando Boero (mwangwiro kwa mwini kafukufuku wawo) anabzala mu Aquarium modabwitsa a mitundu. Poyamba, palibe ali nawo bwinobwino, mwina chifukwa choti sangathe wodzichepetsa kukula (5 mm) ndi maonekedwe nondescript kwathunthu. Pa zifukwa zina zatsopano wasayansi anayenera kudzachitike, ndipo anaiwala pitomitsy wakeyo. Ndinakumbukira pamene Aquarium ndi wauma ndipo anthu ankaoneka kuti afe. Boero anaganiza kuziyeretsa ku Aquarium, ndi kudzaza ndi experimental zotsatirazi, koma ndi chidwi nthawi zonse, anaganiza zoyamba kuphunzira modabwitsa kale zouma.

Kodi zinali anadabwa atazindikira kuti iwo sanafe, ndi kukhala mphutsi. Iye anadzaza thanki ndi madzi. Patapita mphutsi nthawi poluzasohshie kukhala ndi tizilombo ting'onoting'ono, imene kenako anawomba nsalu pa modabwitsa latsopano. Kotero kunapezeka kuti utitiri Turritopsis nutricula - sufa modabwitsa, zomwe zimapangitsa zimaoneka zovuta. Mozama chibadwa chake komanso akhoza "kusuntha chammbuyo", mwachitsanzo. E. MBABWERERA KWA siteji koyamba chitukuko ndi kuyamba moyo. M'mawu ena, wachisavundi modabwitsa Turritopsis nutricula sichingataike chifukwa m'badwo likuyandikira. Iye afa, ngati munthu anadya kapena anang'amba.

Asayansi amakhulupirira kuti kakang'ono wosafa modabwitsa - ili ndi thupi lapansi okha amene buluzi ndi rejuvenate nokha. Komanso, dongosolo adzabwereza izo nthawi zosawerengeka. Wosafa modabwitsa Turritopsis wa mtundu Hydroids, amene mamembala moyo mu nyanja ya mabacteria ndi kotentha ndi otentha. Kuti mtundu uwu ndi atsamunda coelenterates m'madzi, womwe ndi tizilombo ting'onoting'ono, madera amene wapangidwa anthu mazana angapo. Iwo - ngati tchire, ndipo komabe mwamphamvu Ufumuyo gawo lapansi ndi. Ngakhale pali umodzi. The umodzi njuchi matumbo polyp M'mimbamo chikugwirizana ndi wamba mwa njuchi lonse la E. patsekeke. M'mawu ena, onse ogwirizana ndi "m'matumbo wamba", limene pali yogawa chakudya zonse wagwa.

Wosafa modabwitsa ali mzikiti mawonekedwe ambulera, m'mphepete mwa corolla ndi a tentacles lapansi. Ndipo chiwerengero cha tentacles kumawonjezera ndi zaka: kumene anawomba nsalu kuchokera modabwitsa adzakhala zosaposa 8, komanso m'tsogolo chiwerengero zingawonjezere magawo 90. Medusa mbali ziwiri: woyamba - ndi polyp, wachiwiri - chabe modabwitsa. Monga otsiriza, zingakhale kwa maola angapo kapena miyezi ingapo, ndiyeno abwelela ku sitepe yoyamba, umasinthasintha kubwereza mkombero.

Wosafa modabwitsa mbadwa ku Caribbean, koma lero kale m'madera ena m'mayiko ambirimbiri. Izi zinachitika chifukwa chakuti Turritopsis nutricula kwambiri zikuchulukireni. Ena amakhulupirira kuti zimenezi kuchuluka zingachititse kuti kuswa nyanja bwino. Koma Maria Miglietta (Dr. Otentha Institute Research) akukhulupirira kuti sitiyenera nkhawa m'mizere malo onse a mtundu umenewu hydroids. Mu Turritopsis nutricula zambiri zimadya adani, amene zikugwira kupulula ana awo. Koma mwina, sikokwanira, chiwerengero cha modabwitsa wosafa chaka zikuchulukirachulukira.
