Usingafi muramba Turritopsis nutricula

Munguva ichangopfuura, masayendisiti kuziva muramba Turritopsis nutricula. Ndizvowo zvinogona ndirumbidzwe zvakanyanya nezvokurara, uye kunyanya nhaka kwezvinhu zvisikwa nyore zvakadaro? Zvino vose vari inotevera yokutanga. A musayendisiti wokuItaly Fernando Boero (setsikawo nokuda kwavo pachavo tsvakurudzo) wakasimwa kupinda akwariyamu muramba kwemarudzi. Kare, hapana munhu ane kwazvo, zvichida nokuti vachiri mwero saizi (5 mm) uye zvachose nondescript chitarisiko. Nokuda kwechimwe chikonzero, musayendisiti kuedza aifanira kumbosiyiwa, uye iye Vakakanganwa pitomitsy yake norugare. Ndakayeuka apo akwariyamu hwaoma, uye vagari sokuti kufa. Boero akasarudza kuchenesa kubva akwariyamu uye muzadze pamwe inotevera experimental, asi yake zvatinosiita kuziva, akasarudza kudzidza muramba kare yaoma.

Zvazvakanga Akashamisika payakafukidzwa yakawanikwa kuti havana kufa, uye kuva mazana. Akavazadza zvakare mota nemvura. Kwapera nguva poluzasohshie mazana kuva polyps, umo gare gare vakakosa kure muramba itsva. Saka vakatendeuka kuti nhata Turritopsis nutricula - haufi muramba, izvo zvinoita kuti zvinoita sezvisingabviri. It unoshanda pachake majini ayo uye vanogona 'kufamba shure ", kureva. E. Unodzokera kune kutanga kwekupwanyiwa kukura uye kurarama zvakare. Nemamwe mashoko, usingafi muramba Turritopsis nutricula hazvigoni kurasika nokuda kuuya zera. Iye akafa, kana munhu akadya kana akabvambura.

Masayendisiti zvino tenda kuti duku usingafi muramba - iyi ndiyo chete muviri yepasi kuti anogona panoda uye kusimbisazve pachako. Uyezve, uku kutenderera kudzokorora izvozvo kasingaperi. Usingafi muramba Turritopsis ndowenyika genus Hydroids, ane nhengo kurarama mumakungwa ari dzinodziya uye dzinopisa zvikamu. To genus iri yaitonga zvomumvura coelenterates, dzinova polyps, dzaidzorwa izvo akaumbwa anoverengeka zana vanhu. Ivo - kufanana mumakwenzi, uye vachiri zvakasimba vasiyana substrate. Kunyange zvazvo pane chimwe. The chete nyuchi intestinal polyp mhango zvakabatana zvakajairika kuburikidza yose muhutongi E. mhango. Nemamwe mashoko, ivo vose vakabatanidzwa "vanhuwo dumbu", ine kugoverwa kwezvokudya zvose rawa.

Usingafi muramba ane nzvimbo chimiro amburera, pamusoro pamuuyo Corolla ndiko tentacles. Uye nhamba tentacles kunowedzera nezera: mune richangobva vakakosa kure muramba vachava anopfuura 8, uye munguva yemberi nhamba kuchawedzera 90 dzakabatana. Medusa muzvikamu zviviri: chokutanga - the polyp, wechipiri - chete muramba. Semvura yokuteverera, zvinogona kubva akawanda maawa kune yakawanda, uye ipapo anodzokera wokutanga danho, nokusingaperi vachidzokorora ichitanga.

Usingafi muramba chizvarwa kuenda muCaribbean, asi nhasi watova kuwanikwa dzimwe nenzvimbo nzvimbo. Izvi zvakaitika nokuti kuti Turritopsis nutricula vakawanda kwazvo. Vamwe vanodavira kuti zvakadaro kuwedzera uwandu zvingaita kuti rwakavhunika munyanza pachiyero. Asi Maria Miglietta (Dr. Tropical Research Institute) anodavira kuti hatifaniri kunetseka achizadza zvose reservoirs kwaiita hydroids. In Turritopsis nutricula akawandisa zvikara vavengi, vari mubasa kuparadzwa yevana vavo. Kunyange, zvichida, hazvina kukwana, sezvo nhamba haufi muramba nerimwe gore iri kuwedzera.
