Umkhumbi worm: incazelo, izici, futhi izici ekilasini

Kulesi sihloko sibheka izici isakhiwo molluscs, ezibizwa ngokuthi "umkhumbi worm". Cha, singazi wenza iphutha - izilwane ezinjalo zikhona.

Umkhumbi worm: isigaba futhi uhlobo isilwane

Into wukuthi worm umkhumbi, olubizwa nangokuthi teredo, noma umbazi, ngokuhamba yokuziphendukela kwemvelo iye yashintshwa abalulekile. Ikakhulukazi kumayelana Sakhiwo sangaphandle wesilwane. Ngakho-ke, Uma unganakile, kunzima ngempela ukuba wazi ukuthi yini umkhumbi ekilasini worm. Eqinisweni, ummeleli subkingdoms ezinamangqamuzana amaningi futhi uhlobo shellfish. Kwavulwa ikilasi esimele worm umkhumbi, ngokuthi "Bivalve".

sakhiwo sangaphandle

Teredo umzimba has simise cylindrical esifinyelela ubude elilodwa. Njengoba worm umkhumbi kungokwalabo ekilasini bivalves, it has izici esingokwemvelo kwesakhiwo. is kungene kujule kuphi? Itholakala ekupheleni phambi umzimba futhi siqukethe enezinto ezimbili elincane labantu abangaba ngu-1 cm. Ngosizo lwabo imbaza sokuzivivinya ugodo. kwakhiwa leaf ngasinye by izingxenye ezintathu ne imiphetho jagged.

Kungenjalo imbaza isakhiwo shipworm inezici ayisibonelo salokhu amayunithi ehlelekile. Isidumbu sakhe isicaba singatsheki futhi siqukethe ukwahlukana amabili: esifubeni kanye nasemilenzeni. Njengoba izimbaza akudingeki amakhanda, futhi abanayo imizimba, etholakala kulo. It tentacles, pharynx, nolimi nge grater, nemihlathi nezindlala salivary. Isiphuku ihlanganisa ingxenye esemuva zemizimba yabo. Lapha sahlela nezindlala ukuthi secrete calcareous izinto.

Cishe yonke indikimba umkhumbi worm phansi kwezinkuni. Uma uyikha phezulu le, kukushiya kuphela ekupheleni emuva kanye no-pair of namapayipi amunca amanzi. Ngabo eyenziwa ubuhlobo isilwane nge imvelo. Enye ukuzivikela indlela teredo ezithakazelisayo. Kanye USiphon, ngesikhathi sokuphela ezingemuva somzimba ipuleti okuqinile carbohydrate chitin. Uma kwenzeka ingozi, isilwane udonsa namapayipi amunca amanzi enkambweni ukhuni. Ngakho imbobo uvala ipuleti chitinous.

ukukhahlamezeka kwendawo

Zonke bivalves ukuphila emanzini. Bona ingatholakala zonke izilwandle, ngaphandle kuphela abandayo kakhulu. Lokhu kungenxa yokuthi bondliwa filtration. Umkhumbi isihlava sidlula amanzi USiphon kusukela izinsalela organic yawo. Omunye umthombo wamandla teredo kuyinto izinkuni. benza ihamba Nge igobolondo encishisiwe. Ngakho-ke teredo bahlala ukhuni zinsika nemikhumbi, Driftwood, iwela phansi, futhi rhizomes nezitshalo zasolwandle.

sakhiwo sangekhatsi

Njengazo zonke mollusk, izimpethu zasolwandle abe yesibili umzimba ingaphakathi. Nokho, igebe phakathi izidumbu zigcwele ezicutshini okuxekethile. Ihlelo lokukhambisa iingazi sesilwane - ayivaliwe. Siqukethe izitsha inhliziyo negazi. Igazi kusukela Umthambo ingena ngaphakathi komgodi umzimba. Lapha-ke ixubene uketshezi, futhi izona zonke izinhlaka. Kulesigaba exchange igesi. Igazi engena enhliziyweni ngemithambo. Umkhumbi impethu - izilwane nongenanembeza. Ngakho-ke, ukuphila ngamanzi abandayo kakhulu, akakwazi.

Borers izitho zokuphefumula kukhona gills, nge okuyinto bumunca umoya-mpilo emanzini. Uhlelo excretory imelelwa nezinso. imikhiqizo umzimba sisodwa okolomantiynuyu ingaphakathi. Umkhumbi isihlava isimiso sezinzwa has uhlobo ehlakazekile-engeyokuqala.

Izici zokuphila

Umkhumbi nezibungu esenzweni njalo. iminithi Omunye benza ini mayelana eziyishumi-imishini ukunyakaza. Ngesikhathi esifanayo baphokophelele Sash, okuyinto ukubhubhisa izinkuni zawo jagged. Ubukhulu of worm umkhumbi uphendulela senyukile njengoba isilwane uqobo. Abakwazi afinyelela 2 amamitha ubude ngenhloso ububanzi ka 5 cm With le ndlela yokuphila ingenye ngaphezulu igama labo -. Umbazi. Okumangazayo ukuthi lezi uhamba clams neze aphambana. Ososayensi basikisela ukuthi uzwe umsindo okusondelayo imishini "umakhelwane" futhi ushintshe isiqondiso sabo. Nansi inhlonipho izilwane komunye nomunye!

Ukuze eziyinkimbinkimbi carbohydrate Ukugaya cellulose, esakhiwa ukhuni, kudinga enzyme ethile. Teredo ayikwazi ngokuzimela nokuwakhiqiza. Isakhiwo engavamile ohlelweni lwabo kokudla khona yayifanekisela nomxhantela eside izimpumputhe isisu, okuyinto njalo ukuqongelela chips. Lihlala amagciwane iqala ubuhlobo bokubambisana. Bona ninamathele cellulose ukuze glucose monosaccharide. Omunye umsebenzi iqala ubuhlobo bokubambisana nitrogen nenkanuko edlulele kuyinto asemanzini.

Lokuzaliswa nokuthuthukiswa

Umkhumbi izimpethu - hermaphrodites. Lokhu kusho ukuthi umuntu indlela ethile kokubili ama-germ cells owesilisa nowesifazane. Amaqanda avundiswa kukhona umgodi wokuqala branchial lapho ukuthuthukisa amasonto 3. izibungu zabo ukuthuthukisa kubo. Bayaphumela emanzini ukubhukuda lapha omunye amaviki 2. Umlenze silwanyana iqala ukukhiqiza amaprotheni izidakamizwa ezikhethekile ngesimo intambo - bisus. Ngalo, isibungu unamathele ugodo. Phakathi nale nkathi teredo has ukubukeka ejwayelekile bivalve. Iningi umzimba wakhe ukufihla amagobolondo, zazo umlenze kuphuma kubonakale. Njengoba isilwane siba njengomuntu isibungu.

Inani bemvelo ukuphila komuntu

Umkhumbi izimpethu kufanele wathola enkazimulweni ezimbi. Empeleni ngibabheka njengomndeni ukuletha eziningi umonakalo ngokubhubhisa ugodo yabo ihamba. kuyingozi ikakhulukazi lezi zilwane kwakufanele endulo, lapho abantu wayengazi ukuthi balwa nabo. Umkhumbi izimpethu bayakwazi ukubhubhisa ngokuphelele phansi noma uhlangothi umkhumbi, kanye naye othulini amabhuloho futhi zinsika ukwesekwa, ukubangela ukufa nezitshalo zasolwandle. Manje nokhuni, okungakwazi abe "isisulu" lomkhumbi izimpethu, embozwe izinto ezikhethekile anobuthi ezenza kube "engenakudliwa ngobubi bawo" yedatha shellfish.

Ngakho, umkhumbi izimpethu, naphezu kwegama layo, yizona ezimelela nekilasi "Bivalve molluscs". Bahlala cishe zonke izilwandle, sokuxazulula phezu kwezinkuni izinto. Lezi zilwane unayo i umzimba side esithambile futhi ezimbili encishisiwe uhhafu igobolondo. Ngosizo lwabo, benza uhamba ehlathini, ngaleyo ndlela angagcina futhi enza umonakalo omkhulu.
