I-Polyp i-Polyp iyisidumbu esinqabileyo

I-Hydra yintsapho ekhethekileyo ekwaseklasini yama-polyps polyps, uhlobo lwama-coelenterates. Bahlala kuphela kwimigodla yamanzi ahlambulukileyo, amaninzi agxininiswe needuckweed. Bakhetha ukuhlala kwindawo eqaqambileyo yamachibi kunye namanxuwa, ngenxa yokuba bathanda ilanga. Bondla ngamanzi, iifubhu ezincinci zamangqamu, i- fry, i-cyclops, iplankton yamanzi.

I-Polyp hydra ngobukhulu ifana nengqolowa yebhali. It is translucent, grey in color. Ngakolunye uhlangothi, unomngcipheko owenza imisebenzi yomlomo kwaye yenzelwe ukukhipha imveliso yomsebenzi obalulekileyo, ujikelezwe yimithwalo. Ngakolunye uhlangothi, kukho okubizwa ngokuba yedwa, apho ixutywa emanzini afakwe emanzini.

Umzimba uqulethe iintlobo ezimbini zeeseli-zangaphandle nangaphakathi. Ingaphakathi lonke liphela emathunjini emathumbu. Ukuphefumula kuqhutyelwa ngumhlaba wonke.

Emva kokuthatha indawo ezinzileyo, i-hydra yamanzi iyama ngokulindela ixhoba. Kwiintente zikhona i-cilia encinci ekunceda ekufumaneni ixhoba elisondelayo. Emzimbeni womzimba, i-hydra, ikakhulukazi kwiintente, zinemizimba eneenwele ezijikelezayo ezine-capsule enetyhefu. Xa ixhoba lidibene nelo lisele, inetyhefu edibeneyo iyayibulala. Iimpawu zeHydra zinyusa ixhoba emlonyeni womlomo kwaye uyigxume.

I-Polyp ye-Polyra yindoda yelusi. Unako ukutya umthamo wokutya kathathu. Ukutya ukutya ngokukhawuleza kungena emathunjini emathumbu, apho ichithwa ngokukhawuleza.

Ukuba ii-hydras ezimbini zibanga ixhoba elinye, ziqala ukusondeza ixhoba kumacala amabini. Xa uqhagamshelana naye, umkhulu, onamandla unogqithisa encinci. Kodwa ukuphazamiseka, ukugwinya kwe-hydra akufi. Emva kwithuba elithile liphuma kwi-inside of the swallow. Emva kokutyelela isigxina samathumbu esiswini, "ukugubha", ufumana indawo efanelekileyo, uyamlingana aze ayeke ukulindela ukutya.

Amanzi amanzi aHydra anokuvelisa ngeendlela ezimbini: nge-budding (ngokungenasini) nangokwehlula (ngokwesondo). Kwindlela yokuqala, enye okanye ukukhula okuqela kumzimba wakhe, oya kuthi, xa uvuthiwe, uhlukaniswe "nomama". Kwinyanga enye i-hydra ingadala abantu abafana no-15. Le ndlela elula ivelisa, kuba uninzi lwabantwana lulutho luphila.

Uhlobo lwesibini lokuvelisa lusetyenziswe xa kunqongophala kokutya. Ngaphantsi kwesondlo, ukubunjwa kweeseli zesini kwenzeka . Kwaye kwabanye abantu, iiselini zesilisa zenziwe, kunye nakwezinye - iibhinqa. Emva kokuchumisa iqanda lenziwa, umzekelo omdala ufe, kunye neqanda eliye lahla liye lisezantsi kweli gumbi. Emva kokulala ixesha elithile, i-hydra inokuyifuma kuyo entwasahlobo, kodwa ngokufuthi iyafa.

I-polyp yamanzi yamanzi ayinakulinganiswa ubuninzi bobomi. Ukuba kuyimfuneko, inokuhambisa, ukuguqa umzimba kunye nokuhamba kwedwa. Ukufumana ikhaya elitsha, litsalwa.

I-Polyp hydra ibonakaliswe ngamandla aphezulu okulungisa izixhobo ezonakalisiweyo okanye ezilahlekileyo zomzimba (ukuhlaziywa kwakhona). Xa umntu omnye enqunyulwa kwiingxenye ezimbini, engalingani, i-hydra i-deux ibe. Iingcali zenzululwazi ziye zafakazela ukuba i-hydraire yezemvelo ayifi.
