Ezingenamgogodla

izilwane ezilwane ezingenamgogodla - abameleli eziningi zezilwane ukuthi ungenalo backbone. Lesi sigaba sihlanganisa ezingabonakali ngeso lenyama (owumphumela), ama-worms ephansi, ama-sponge eyisinambuzane, ama-mollusk echinoderms, nabanye. Sekukonke, leli qembu nesithupha izinhlobo.

Ukuhlukaniswa kwezilwane ku ezilwaneni ezinomgogodla ezinamehlo ezingenamgogodla Lamarck yaqaphela 1801. Phakathi yezilwane ezinomgogodla eyaziwa mayelana zinhlobo ngamashumi amane anamahlanu amawaka. ezingenamgogodla eqaphelekayo ekhona isamba 1 million 260 ayizinkulungwane zilwane. Kulokhu, elula - mayelana ngamashumi amabini anamahlanu amawaka, izipanji - engaba mihlanu, izimpethu ephansi - cishe abangamashumi amabili, mollusk - engaphezu kwekhulu, eyisinambuzane - mayelana zinhlobo ayisikhombisa nesishiyagalolunye namakhulu.

Abantu abaningi zama-izinambuzane ethulwa. Kwakumelwe ayisigidi. Kulokhu, izinambuzane zasemanzini kukhona oda eziningi. Kufanele kuqashelwe ukuthi amanye awo asemanzini ngesikhathi elalikudle lapho liseyisibungu kuphela. Nakuba abanye kuwo lokuphila. Coelenterates izilwane cishe namakhulu ayisishiyagalolunye zilwane. Kumele kuqashelwe ukuthi lezi zinhlobo ekhona imvelo okuningi kunalokho waziwa. Ngaphezu kwalokho, izinkulungwane eziningana kunqunywa minyakayonke amasha.

Ezingenamgogodla hlala emhlabathini, olwandle, nasemachibini, imifula, amachibi, amachibi. abameleli abaningi izimuncagazi. Kulokhu, zingabantu yisinanakazana phezu kwezilwane, futhi izitshalo.

Indima ezingenamgogodla ngokwemvelo mikhulu. izinsalela Solid Abamele, owaphila ekuqaleni nezikhathi Geological, baba izakhi yamadwala, futhi kwezinye izimo - omningi. Ngokwesibonelo, amathambo ezilwane ezilwane ezingenamgogodla, yokuqothulwa, cishe ngokuphelele ezakha namathempeli ngokhonkolo namatshe.

ukubaluleka olungafani leli qembu futhi ngamunye. Ngokwesibonelo, ezingenamgogodla abaningi, kanye imikhiqizo yabo imfucuza esetshenziswa ukulungiselela ukudla kwabantu (uju, isibonelo). abameleli abaningi esetshenziswa ukondla commercial izinhlanzi, izilwane, izinyoni. Amaparele, amagobolondo of mollusk ngengcina yezinyosi , kanye nabanye abameleli abaningi emaqenjini kwezilwane ezilwane ezingenamgogodla ebonakala imikhiqizo imfucuza ongowenani elikhulu kwezomnotho kanye lobuchwepheshe. Avame elisetshenziswa control inkathazo. Ezingenamgogodla kukhona izilwane ezidla ezinye kanye nezinambuzane, ukuze awabhubhise. Le ndlela iphathelene izindlela begazi yokulawula inkathazo. Izazi zesayensi yokwakheka komhlaba ekunqumeni yobudala sedimentary amatshe zahlola izinsalela ezingenamgogodla wezinsalela zamandulo.

Nokho, ngokwemvelo, kukhona eziningi eziyingozi yaleli qembu. ezingenamgogodla Ziningi abathwali pathologies yisinanakazana futhi ezithathelwanayo, izinambuzane lamabele imikhiqizo yayo. Zingaba ezinobuthi futhi umonakalo izitshalo, emahlathini njll

Indawo ekhethekile eqenjini ukuthatha coelenterates. Lapho echaza ngokwesiko ibonisa wesimethri osabalalayo, futhi ezimbili izingqimba lwegciwane (yi-ectoderm futhi endoderm). Ngokuvamile lokhu kubhekwa Owadala umzimba Isilwane kusukela izingqimba ezimbili EPITHELIAL: integument (epidermis) futhi abami mafutha anciphisa isikhala esingaphakathi emathunjini (gastrodermisa). Phakathi laphakathi elise zezinzwa ungqimba gelatinous (mesoglea). Ngo oyiyo iqukethe Imicu yotshani collagen namaseli amoeboid e esincane.

Thina abamele coelenterates Awekho ezikhethekile izitho zokuphefumula kanye excretion. It kuvame ukuhlotshaniswa isakhiwo ezimbili ungqimba isakhiwo, esinikela contact lamaseli iningi epithelia nge imvelo bangaphandle.

Ukuze coelenterates libhekene ampofu isimiso sezinzwa. Iningi ucansi okusakazwa futhi elinesimo ukucaca noma izibungu planktonic.
