A ezihlukahlukene izilwane. Izinto ukuze Isifundo

Ngo biology, zonke izinto eziphilayo, futhi khona emhlabeni, zihlukaniswe ngamaqembu amane omkhulu ngokuthi imibuso. Lokhu amagciwane, izitshalo, isikhunta nezilwane. embusweni ngasinye sibandakanya ezihlukahlukene izizukulwane nezinhlobo ehlanganisa inani elikhulu amayunithi. Amazing kanye ezihlukahlukene enkulu izilwane zasendle. Futhi, izilwane zihlukaniswe owumphumela futhi amaningi, ezilwane ezingenamgogodla kanye yezilwane ezinomgogodla eziphilayo. Isayensi ekubhekaneni ekutadisheni kwabo libizwa kwezilwane (biology kwesigaba).

A ezihlukahlukene izilwane: ngezigaba

Ezingenamgogodla ngokuvamile ezihlobene izimpethu, ama-mollusk echinoderms, ezinamagobolondo, arachnids nezinambuzane. Lezi zilwane (yebo, izimpethu - futhi izilwane) abanalo ngaphakathi noma ngaphandle umgogodla evelele. Ngezinye izikhathi lapho igobolondo chitinous ukuthi wenza lo msebenzi. Ezilwaneni ezinomgogodla zihlanganisa inhlanzi, izilwane eziphila emanzini nasezweni, ezihuquzelayo, izinyoni, izilwane ezincelisayo (abantu libhekisela isigaba odlule, ngoba feeds abantwana babo ubisi lwebele).

Ezingenamgogodla: Worms

A ezihlukahlukene izilwane zasendle ungase ucabange, ukutadisha lezi izidalwa. Leli qembu kuhlanganisa engaphezu kuka-46 eziyinkulungwane zinhlobo zezinto eziphilayo. Izikelemu bashukunyiswa esebenzisa imisipha nokunwebeka nge eguqa umzimba bacondze etindzaweni letehlukene. Zihlala kwezilwandle, emifuleni, emachibini, emaxhaphozini, emhlabathini. Bright, omele owaziwa - the okusasibungu. It uhlala emhlabathini, ekusizeni ukuze kuhlukaniswe futhi imvundo. Kubalulekile kakhulu zonke izinhlobo umsebenzi epulazini. Eziningi zalezi amakilasi izimpethu ewusizo. Ngokwesibonelo, umnyundu. Zisetshenziswa imithi. A izimpethu zasolwandle ukukhonza njengephayona ukuphakelwa okulinganayo ngoba inhlanzi commercial kuvuna abadobi. Ngaphandle kwawo, izinhlobo ezithile zezinhlanzi zingeke ziphinde zibe khona ukudla. Nokho, kukhona ama-worms eziningi yisinanakazana ezikhona ngezithukuthuku nezinye izinto eziphilayo (izimuncagazi kuwo). Ngenxa ukuntula inhlonipho inhlanzeko yomuntu siqu izimuncagazi ezinjalo angangena futhi ngaphakathi emzimbeni womuntu futhi siphile khona iminyaka. Ngakho manje ubone ukuthi kubaluleke kangakanani ukulandela imithetho elula kwenhlanzeko: ugeze izandla ngaphambi kokudla, ungayisebenzisi izitsha ezingcolile, ukungavumeli khona izimpukane. By endleleni, ama-worms, ukuyohlala nezinye izinto eziphilayo ezishisa kakhulu zikhipha izinhlayiyana imikhiqizo eyingozi empilweni yabo, kancane kancane ushevu enkosini yayo. Umuntu uba wethukile, konke yakhe ecasulayo, washeshe Ufika bakhathala futhi buthaka, kukhona ukudakwa njalo, futhi kufanele ube ukuphazamiseka sina odokotela ekususeni izindlela ezikhethekile lonke leli izilwane nomzimba womuntu.

clams

Ukwehlukahluka kwezimangaliso izilwane futhi clams ezinkulu. Leli qembu has ezingaphezu kuka-130 eziyinkulungwane zilwane. Futhi ukuphila cishe noma kuphi, ngisho nezihlahla. Kodwa iningi labo uhlala olwandle ekujuleni ezahlukene. Ezinye zazo zinamakhulu eminyaka zikhona. Shellfish ekhasini kokubili izitshalo nezilwane ezincane, kanye imfucuza eziphilayo. Cishe bonke avikelekile ngesimo igobolondo (ngaphandle, isibonelo i-squid, naye imbaza, kodwa unamandla futhi nokuqala kokuhlala kwezingxenye igobolondo). Sekuyisikhathi eside abantu kudliwe shellfish sokudla. Ezinye amalungu aleli qembu kukhona ngisho izibiliboco.

echinoderms

Lokhu starfish (1,500 zinhlobo), lethiwa ngenxa imisebe emzimbeni (abaningi eziyisihlanu kuzo, kodwa abanye ngisho akhawunti izingcezu kufika ku-50). Izinkanyezi, abahlala kolwandle, zihlukile ngobukhulu futhi ukubukeka. Sici isici starfish - ikhono sikhiqize (njenge izibankwa). Uma nemilenze wesilwane elinqunywe ke endaweni yayo ke liyakhula libe izinga entsha. A ugongolo ka bathinteka ngabanye entsha eba ngaphansi kwezimo ezimvunayo. Iningi starfish - eziyingozi.

sea urchin angasogwini (800 zinhlobo) futhi basonta echinoderms. urchin umzimba embozwe izinaliti ezinobukhulu obuhlukahlukene. A obuphelele kuhlume ongafinyelela 30 amasentimitha. Jerzy ukuhambisa ngosizo izinaliti. Kodwa kwakukhona abanye kubo anobuthi kakhulu, esiyingozi kwezinye izilwane.

ezinamagobolondo

NgoLwesine kutholakale isidumbu sendoda lezi zilwane siqukethe izingxenye armored: ikhanda, thorax nesisu. Nemilenze, okuyinto zitholakala ku esiswini nasesifubeni, ukuvumela zomdlavuza ukuhambisa yonkana kobuso. Amehlo abo akhiwe izimbobo eziningi ezincane, futhi ekhanda kukhona amabhangqa amaningana emihlathini.

Arachnids nezinambuzane

A ezihlukahlukene izilwane eziphilayo emhlabeni, limelelwe kahle, futhi la maqembu, lapho kunezinhlobo ezingaphezu kuka 27,000 zinhlobo. La maqembu amabili ahlobene. izinambuzane kuphela Zinemilenze eyisithupha kanye izicabucabu - eziyisishiyagalombili. Kepha kukho konke izinambuzane amaphiko, ngisho isakhasa. Izicabucabu amaphiko azitholakali. Futhi, isakhiwo somzimba lihlukile: isinambuzane has a ikhanda, thorax nesisu, futhi izicabucabu - cephalothorax nesisu.

ezilwaneni ezinomgogodla ezinamehlo

A ezihlukahlukene izilwane eziphilayo eplanethini yethu, kulula ukucabanga ukuthi izinto ngeke kokuhlola yezilwane ezinomgogodla squad. Le nhlanzi, embozwe izikali. Ziyakwazi ezihlukahlukene zezinto eziphilayo, phakathi okuyinto yasendulo kakhulu ayehlala olwandle kusukela kudala (oshaka, izinhlanzi crossopterygian). Lokhu nezilwane eziphila ezweni nezilwane ezihuquzelayo, futhi izinyoni, nezilwane ezincelisayo ezihlala emhlabeni. Ukwehlukahluka kwezimangaliso izilwane omkhulu kangangokuthi ngisho sezilwane abanolwazi akukuniki impendulo eqondile embuzweni ukuthi izinhlobo eziningi ezikhona emvelweni. Ngoba akukho impendulo eqondile futhi: njalo ekuvuleni ezisanda kutholakala, ezinye izinhlobo zezinto eziphilayo zinyamalale. It eyenziwa umjikelezo bemvelo, okuhlanganisa i Izinhlobonhlobo eziningi zamakhekheba izilwane (bheka ngenhla isithombe).
