Urchins Sea - Denizens Enzulwini

Xa iinzulu zolwandle ne etyuwa yolwandle zizilwanyana emangalisayo - urchins yolwandle. Le સંસાધક isisebenzisi njengezinambuzane kokwabo udidi echinoderms. umzimba lokhwalimanzi has a encinane (3-30 cm), wayifulela amacwecwe shell calcareous ukuba abaqhagamshelwe ezahlukeneyo kunye ubude yenaliti. Kuba iyimfuneko intshukumo isilwanyana. Eyes ibekwe emzimbeni eliphezulu.

Kwindalo, kukho urchins ulwandle ipeyinti kakhulu ezimbini: obomvu, omhlophe, emnyama, eluhlaza, oluhlaza, omdaka, purple kunye hina. Ezinye iintaka ukutshintsha umbala ngokuxhomekeke ngumsindo. Inani elipheleleyo izikhonkwane, banikwe iikomityi sokufunxa kwaye ibekwe wonke umzimba, kuba ngaphezu kwamawaka. Bayakwazi ukuba olule kwaye isivumelwano, ukuze isilwanyana kungaba ukukhasa ngokulula ukusuka kwindawo ukuya kwindawo, kwakunye ungalawula ngapha emaweni. Mouth, liqiniswe ulusu ethambileyo, ubunjwe izibini ezintlanu amacwecwe ihlafuna asondezwe, kungqameko ezo iigilizi yangaphandle. urchins Sea babe amalungu ezizodwa lizama - sferidii. Bona ibekwe emlonyeni. sea has amalungu ebambayo ezikhethekileyo - pedicellariae asemaphandleni ezi naliti. Bona banikwa intloko esinetyhefu ulwelo eziveliswa namadlala ezizodwa. Ubuhlungu Animal yityhefu kakhulu. Nalo lokhwalimanzi besilwa neentshaba. Noko ke, asiyiyo kuphela umsebenzi pedicellariae - Bulelani kubo, lokhwalimanzi ecoca umzimba wakho kwenkunkuma kunye ezingcolisa ezahlukeneyo, ayithimbe okuphangiweyo, kwaye edlulisela kwi emlonyeni.

Arthropods kuhlala kubunzulu yeemitha elishumi, ubukhulu becala kufutshane lezixhobo kunye namanzi onxweme. Nangona ukufumaneka ezahlukeneyo iindlela ukukhusela (i pedicellariae inaliti, iintonga), izilwanyana ngokufuthi bangamaxhoba izilwanyana ezinkulu, ezifana no kwikala elwandle, intlanzi, isilwanyana, ezanyisayo zaselwandle kunye neentaka.

Zizalana abantu kuqalisa emva konyaka wesithathu wobomi. iiseli intsholongwane e arthropods kufuphi empundwini. urchins ulwandle uhlobo inokuba ngeenxa nyaka. Noko ke, uninzi ixesha lokukhwela kwenzeka ngexesha efudumeleyo lonyaka. Ekubeni ezi izilwanyana zasemanzini dioecious, neencanda ezizalayo na ngolu hlobo lulandelayo: i-izala amaqanda ayo emanzini, kwaye ngoko ke amadoda umgquba. Izigidi iiseli lwegciwane inkunzi wamatyhalarha ezintweni arthropods baselwandle, iiyure ezimbalwa nje ibe amaso ezincinane isale imicu ezibhityileyo. Ngenxa ukungcangcazela zabo, amaqanda bayakwazi ajikeleza sihambe ngazo zonke iindlela. Emva kwethutyana imibungu zilungiswe apha: Wasolula, ekusekeni amathambo obhityileyo kakhulu calcareous kunye nenkqubo ezine. Ukususela ngelo xesha, amaqanda balahlekelwe ukubagcina zabo zangaphambili, kunye kubathwala phezu kumacala ahlukeneyo. Ebudeni bexesha-hamba kunye milo kwenzeka. Xa isiseko iinkqubo kunye pleutusah ibunjiwe kuphuhlisa sea ezincinane. Ngalo mzuzu, yile mibala kusithwa emazantsi okanye enye umphezulu, kwaziswa isithuba esitsha. Kwabonakala umlenze yokuqala ngokuqinileyo incamathele ematyeni, kwaye isilwanyana iqala ukukhula ngenkuthalo.

In kumazwe eziselunxwemeni eurchin ulwandle iintlobo ekujoliswe. Kumazwe Mediterranean kakhulu ukutya isidoda izilwanyana kunye namaqanda. Noko ke, le lenyule સંસાધક isisebenzisi ukuba kubekho ingozi ethile. Siqubha elwandle, yaye, ngempazamo ndanyathe- lokhwalimanzi, kunokubangela umonakalo omkhulu ukuya elunyaweni. Ukugqobhoza nesikhumba somntu, i iinaliti badla kuyaphula, eshiya umzimba lamacebiso eziyityhefu. Ngenxa yoko kukho intlungu kakhulu elide iiyure eziliqela. Ubuhlungu abathile bale hlobo yityhefu kakhulu.

Nangona kunjalo, iinzuzo engenakuphikwa kunye urchins ulwandle. Bona zaziwa ngokuba orderlies yolwandle enzonzobila, ngenxa namandla wayo icarbon dioxide, ukunciphisa imali yayo emoyeni. Le insides wenkomo ezisetyenziswa kwishishini lamachiza ukudala iziyobisi.
