Mpethu Marine: iintlobo, inkcazo kunye neempawu eziphefumlayo

worms Sea - izidalwa ezingaqhelekanga. Abaninzi kubo khangela ezifana neentyatyambo ezicingelwayo okanye iteyiphu eliqaqambileyo tyaba, yaye kukho iintlobo ezibangela inkangeleko kunye nemikhwa yazo ndiba yokunqakulisa. Ngokubanzi, umbungu elwandle - kukho umdla kakhulu. Kokuba kolyuchegolovogo, polychaete, iintlobo annelid, tyaba, iinwele-ndingumbungu, njalo njalo. Olu luhlu omkhulu ngokwenene. Kweli nqaku siza kuqwalasela iintlobo ezininzi iinkcukacha.

worm Marine tube polychaete

photo Marine impethu leyo ikhangeleka ngathi intyatyambo nezingaqhelekanga, ebizwa polychaete ityhubhu okanye "umthi weKrismesi". Oku kubhekisela uhlobo intsapho eliqaqambileyo Sabellidae. Kwigama lesiLatini isilwanyana - Spirobranchus giganteus, kwaye IsiNgesi - iKrismesi umthi worm.

Ukuphila olu hlobo ziimpethu yolwandle kwindawo lemvula Indian kunye Pacific the Ocean. It ithanda ezinzulwini ezincinane, neekorale bush kunye namanzi acocekileyo.

Kukuziva ukhuselekile, umbungu baselwandle wakha ityhubhu calcareous of calcium carbonate ion. Animal kwizicatshulwa kwakhiwe ngqo emanzini. Kuba ion lungu "Umthi weKrismesi" ichonge becandelo elithile organic amadlala ezimbini ngomlomo. Njengoko worm ikhula, ityhubhu kufuneka kongezwe, isangqa omtsha pristraivaya ukuya ekupheleni yokuhlala endala.

Ezidla tube polychaete ziintshulube ukuba ukhetha indawo phantsi indlu banoxanduva. Baqala zokwakha kuphela kuneekorale abafileyo okanye ababuthathaka. Ngamanye amaxesha ubuthe kumathanga yonke, kodwa sihlale abangatshatanga eziqhelekileyo. Ukwandisa, neekorale ukufihla ifowuni, eshiya phezu kuphela imibala "Umthi weKrismesi" unomtsalane. Ke kaloku, umbala beentshulube ulwandle eliqaqambileyo ngokwenene igcwaliswe. Ifike oluhlaza, mthubi, obomvu, omhlophe, ezipinki, zaqiniswa ngamaqamesi, zinala, kwaye abamnyama. A zisezele ongazikhetha. abantu Neskoro sidibanisa imibala eyahlukileyo.

Beautiful ngaphandle "umthi" - hayi nje uhombiso, kunye reyi kumculo, eziqulathe nomsebenzi ezigqeba ngesondlo kunye nokuphefumla. mpethu zaselwandle nganye reyi ezimbini siba dj.

Malunga ukhuseleko lwabo polychaete annelids kunyamekela ngaphantsi kwendlu yokwakha. Ikalika ityhubhu has isiciko tight, uthathele kwi ugwebu amvalele kwi encinane ingozi worm torque.

Ngokuxhomekeka kuhlobo Spirobranchus giganteus baphile emi-4 ukuya kwi-8.

polychaete

Polychaetes abanamathele uhlobo annelids, iklasi polychaetes. Kwindalo, ukuba kuka-10 amawaka. Types. Abaninzi kubo bahlala kweelwandle, kwaye ezantsi yindlela yobomi. Usapho ngamnye (umz, Tomopteridae) zihlala peraliale (yolwandle evulekileyo okanye ulwandle, Ungandichukumisi ezantsi). kwisizukulwana amaninzi afumaneka emanzini fresh, ezifana Lake zamanzi.

lugworm

Enye abameli lixhaphakileyo polychaete zicingeleka engqongwe iintshulube polychaete zaselwandle, ogama - lugworm. E Latin, kuvakala ngathi Arenicola Marina. Le isilwanyana kunokuba enkulu, ubude bayo ngu-20 cm. Ubomi i impethu zaselwandle Usana arc emile Ndagqobhoza emazantsi entlabathini. Amandla olu hlobo isebenza ndee apho kumpethu udlula amathumbu.

umzimba omdala ibandakanya ezintathu - isifuba, esisu kunye nomsila. I-inshorensi engaphandle iyinxalenye UA yesibini ezo abufani segmentation. Iziqwempu esiswini kumzimba kwimpethu-11, yaye isibini ngasinye afumaneka iigilizi zaziya.

Lugworm komeleza iindonga kumakhaya abo kunye yencindi yomlomo. ngoboya Ubude -. 30 cm Ukususela ndlwana, umzimba worm uye ekupheleni inxenye ngaphambili kwi ngoboya tyaba, yaye ngasemva - kwicala nkqo. Ngaphezu ekupheleni intloko ye kwandlelwe kwakheka kwi hopper ezantsi, ekubeni usoloko edla yodaka. Defecation lobworm ubhenca ngoboya ekupheleni diff. Kweli nqanaba, umbungu yaselwandle nga ngamaxhoba irhamncwa.

nereid

Nereida - annelid zaselwandle. Olu hlobo inyakanyaka isebenza ukutya intlanzi ezininzi zaselwandle. Umzimba kwandlelwe yenziwe komsindo. Phambili sise ngasentloko, apho nemisipha, umlomo, nemihlathi kunye ngambini ngamehlo. Boca ziqwempu banikwe spikes osicaba, ezifana ikhaba. Apha bebekelwa ezifumaneka ezininzi elide.

Xa Nereids kwi ukuphefumla ababandakanyekayo yonke kumphezulu umzimba. uphefumle nje annelid yimisundululu, leyo abaziqhelileyo wonke. lihamba Nereid ngokukhawuleza kokudlula kwi ezimile fan outgrowths. Kulo mzekelo, ezantsi umzimba kuxhaswa besusa ezifumaneka. Kwi menu ukuba annelid zaselwandle kuquka ulwelwe nezilwanyana ezincinane, kuswela imihlathi.

ukuphefumla umkhuba

A indlela umoya, nesetyenziswa nereids, libe nokuthathelwa ingqalelo le hlobo beentshulube ngaphandle. Njani ukuphefumla abanye abameli engqongwe? Yintoni eziqhelekileyo uphefumla annelids yaselwandle? Breath kweentlobo ezininzi kwenzeka Kwakukhuhlwa, ezo zibekwe ekukhuleni-ngamaphiko. Iigilizi babonelelwa inani elikhulu ngcanjana. Enrichment yegazi kunye oksijini evela emoyeni leyo unyityilikiswa emanzini. Apha emanzini uvelisa carbon dioxide.

flatworms Marine

Ezinzulwini olwandle udibana olunye udidi ziimpethu - marine flatworms. Bona ngokuba ciliary okanye turbellarians. Olu udidi babephakathi ngaphezulu kwe-3.5 amawaka. Species. Umzimba igutyungelwe nabameli epithelium ciliated, nto leyo kusinceda. Ezinye abameli turbellarians ingabonwa kuphela phantsi ngemicroscope, kodwa kukho iintlobo ukuba ukufika-40 cm ubude. Phakathi flatworms ukhululekile-eziphilayo iintlobo zaselwandle, kodwa olwaye lwamfimfitha, kuquka tape kuphela.

flatworm Marine - kaninzi nomzingeli. Uhlabela ngamadolo okanye bequbha. Ngaba bilaterally izilwanyana macala. Turbellarians ziye atshabalalisa elimbhoxo umzimba okanye side. Inxalenye phambi mzimba izivamvo, kwaye umlomo kwicala ventral.

iphecana ciliated ntshulube wokudla kuxhomekeke iintlobo. Kunokuba kakhulu likumgangatho ophantsi, okanye mandithi ezintsonkothileyo, kunye emathunjini yegqabi.

Ezinye iintlobo ze yaselwandle turbellarians zala-plain, kodwa kukho umdak enemibala eqaqambileyo, kodwa phawula ukuba nje akunakwenzeka.
