Impethu Marine: izinhlobo, incazelo kanye izici ukuphefumula

Sea izimpethu - izidalwa engavamile. Abaningi babo ibukeke izimbali kumnandi noma elikhanyayo itheyiphu flat, futhi kukhona izinhlobo kubangele ukubukeka imikhuba yabo ukuphahlaza eshaqisayo. Ngokuvamile, worm zasolwandle - kukhona ezithakazelisayo kakhulu. Singasho kolyuchegolovogo, polychaete, annelid zilwane, flat, izinwele-worm, njalo njalo. Uhlu omkhulu ngempela. Kulesi sihloko sizohlola izinhlobo eziningana imininingwane.

impethu Marine tube polychaete

Marine isihlava isithombe okuyinto ifana i imbali ezingavamile, okuthiwa tube polychaete noma "isihlahla sikaKhisimusi". Lokhu kusho uhlobo Sabellidae umndeni elikhanyayo. I-Latin igama isilwane - Spirobranchus giganteus, kanye English - isihlahla sikaKhisimusi worm.

Ukuhlala lolu hlobo ulwandle izimpethu ezonini ezishisayo-Indian nasePacific Ocean Ocean. It ukhetha ekujuleni encane, coral ehlathini namanzi okuhlanzekile.

Ukuze bative bavikelekile, worm zasolwandle yakha ngamapayipi calcareous calcium carbonate ion. Animal adonse yokwakha ngokuqondile amanzi. Ukuze ion umsipha "Isihlahla sikaKhisimusi" likhomba isakhi esithile organic nezindlala ezimbili ngomlomo. Njengoba worm ikhula, tube kumele kwengezwe, pristraivaya indandatho entsha kuze kube sekupheleni of the yokukhosela ubudala.

Izibungu polychaete tube worm zikhetha indawo ngaphansi kwendlu banesibopho. Baqala ukwakhiwa kuphela kwamakhorali efile noma ebuthaka. Ngezinye izikhathi zibuthe amakoloni lonke, kodwa futhi apholile olulodwa ivamile impela. Inwebisa, amakhorali ukufihla ifoni, kusale phezu nenhle ezimibalabala "Isihlahla sikaKhisimusi" kuphela. Phela, umbala ulwandle impethu kuxhopha ngempela igcwaliswe. Iphuma ngombala oluhlaza okwesibhakabhaka, ophuzi, obomvu, omhlophe, pink, variegated, nezimanakanaka, ngisho elimnyama. Amashumi ongakhetha. abantu Neskoro ukuhlanganisa imibala ehlukene.

Beautiful "isihlahla" ongaphandle - hhayi nje umhlobiso, imisebe gill, okuyinto sifeze umsebenzi kwezitho okunomsoco nokuphefumula kwezimila. isibungu ngasinye zasolwandle has Kuvunguza emibili gill.

Mayelana nokuphepha kwabo polychaete annelids anakekele ngaphansi kwendlu ukwakhiwa. Lime tube has lid Friend, bangena itheku futhi amvalele ngesikhathi kancane usongo worm ne-torque.

Kuye uhlobo Spirobranchus giganteus siphile kusuka eminyakeni 4 kuya kwezingu-8.

polychaete

Polychaetes teluhlobo annelids, polychaetes ekilasini. Emvelweni, zihlala abantu abangamaphesenti angaphezu kuka-10 eyinkulungwane. Species. Iningi labo enihlala ezilwandle, futhi phansi kuyindlela yokuphila. Umndeni ngamunye (isib Tomopteridae) akha peraliale (yolwandle oluvulekile noma ulwandle, hhayi othinta phansi). izizukulwane eziningana atholakala amanzi aqabulayo, ezifana iChibi iBaikal.

lugworm

Omunye abameleli ezivame kakhulu polychaete babhekwa ringed izimpethu polychaete zasolwandle, ogama lakhe - lugworm. Lubhalwe ngesiLatini, futhi kuzwakala sengathi Arenicola emtateni. Isilwane kunalokho enkulu, nobude bawo 20 cm. Uhlala worm olwandle Burrows arc emise wemba phansi esihlabathini. Amandla kulolu hlobo ukhonza ezinzulwini okuyinto impethu sidlula amathumbu.

umzimba omdala inezingxenye ezintathu - i thorax, emzimbeni umsila. Ikhava yangaphandle yakha izindandatho yesibili okuyinto ayihambisani izingxenye. izingxenye besisu emzimbeni worm 11, futhi pair ngamunye zitholakala gills lwentshebe.

Lugworm kuqinisa izindonga emizini yabo izimbici. mink Ubude -. 30 cm Kusukela gumbi, umzimba impethu has a front end ingxenye e mink ovundlile, nengxenye yalo engemuva - e ohlangothini mpo. Ngenhla ukuphela inhloko worm Kumiswa phezu hopper phansi, njengoba kuyintando njalo edla inzika. Sokuzikhulula lobworm udalula mink ekupheleni labaqaphi elingemuva. Kuleli qophelo, worm zasolwandle kungaba yizisulu umhlaseli.

nereid

Nereida - annelid zasolwandle. Lolu hlobo ezinwabuzelayo ukuthi ukhonza njengelungu ukudla izinhlanzi eziningi zasolwandle. Umzimba isihlava yakhiwa izingxenye. Ngesikhathi phambi sise ikhanda, lapho ihambe, umlomo, nemihlathi amabili namabhuzu amehlo. Boca izingxenye anikezwa nge spikes flat, efana ukudla. Lapha basuke bagxila bristles eziningi eside.

Ngesikhathi Nereids bokuphefumula abathintekayo bonke ubuso umzimba. Mane uphefumule annelid nemisundu eminingi, okuyinto ujwayelene kuwo wonke umuntu. Nereid uhamba ngokushesha kokudabula fan emise amaqhubu. Kulokhu, phansi umzimba kusekelwa tufts ka bristles. Esikhathini imenyu annelid zasolwandle kuhlanganisa ulwelwe nezilwane ezincane, okuyinto bantule nemihlathi.

umkhuba ukuphefumula

Indlela umoya, esetshenziselwa nereids, kungaba kucatshangelwe lolu hlobo worm ngaphandle. uphefumule kanjani nabanye abameleli ringed? Yini kuvamile ukuphefumula zasolwandle annelids? Breath kwezinhlobo eziningi kwenzeka ngokusebenzisa gills, okuyinto zisekujuleni ekukhuleni-izindwani. Gills unikezwe inombolo enkulu capillary. Kwandzisa igazi nomoya-mpilo ethathwe emoyeni okuyinto ziyoncibilika emanzini. Lapha emanzini ukhiqiza-carbon dioxide.

flatworms Marine

Esikhathini emajukujukwini olwandle ihlangabezana kwelinye ikilasi izibungu - zasolwandle flatworms. Zibizwa ngokuthi ama-ciliary noma turbellarians. Lesi sigaba babephakathi ezingaphezu kuka 3.5 ayizinkulungwane. Species. Umzimba embozwe abameleli epithelium ciliated, esiza ukuhambisa. Abanye abameleli turbellarians ingabonakala kuphela ngesibonakhulu, kodwa kukhona izinhlobo ukufinyelela 40 cm ubude. Phakathi flatworms akuyona kuphela khulula-eziphilayo zasolwandle, kodwa futhi yisinanakazana, kuhlanganise tape.

flatworm Marine - ngokuvamile nomzingeli. Enaka ngihambahambe ngamadolo noma ukubhukuda. Ingabe bilaterally izilwane izinhlangothi zazo ziyalingana. Turbellarians baye isicaba umzimba okusaqanda noma ukuma side. Ngaphambili ingxenye yomzimba kukhona izinzwa, nomlomo ohlangothini ventral.

Wokugaya ukudla ipheshana ciliated izimpethu incike zilwane. Kungaba isintu impela, noma kunalokho eziyinkimbinkimbi, nge esinezimila emathunjini.

Ezinye izinhlobo zama-zasolwandle turbellarians ahlotshiswe-Araba, kodwa kukhona ubuhle egqamile, kodwa phawula ukuthi akunakwenzeka.
