• Ukuhanjiswa kwezilwane ezihuquzelayo
• Ukunyakaza okungenamgogodla kokuhamba
• Izibonelo zezilwane ezinwabuzelayo

Incazelo yesichasiso 'ezinwabuzelayo ' inobudlelwano obuqondile negama 'ukugeleza ', futhi lapho lisetshenziswa ezilwaneni likhuluma ngalabo abahamba ngomhlaba, okusho ukuthi, kulo.

Yize abanye besebenzisa umqondo ukukhuluma ngisho nangezinyoni ezindiza phansi noma ezingeni lomhlabathi, incazelo ngqo yezilwane ezikhasayo yilezo izilwane ezikhasayo. Incazelo ibuye inabele emkhakheni wezitshalo, ngoba izitshalo ezinwabuzelayo yizo ezinweba isiqu sazo phansi.

Ukuhanjiswa kwezilwane ezihuquzelayo

Izilwane ezikhasayo zivame ukuhlotshaniswa neqembu lezilwane ezihuquzelayo, okukhishwa kwazo kuncike ekuhuduleni imizimba, isenzo esinikeza igama laso esigabeni sezilwane ezihuquzelayo. Noma kunjalo akuzona zonke izilwane ezihuquzelayo ezihambayo, ngoba izilwane eziningi zihamba ngaphandle kokuzihlanganisa naleli qembu: ngaphezu kokukhasa, izilwane ezihuquzelayo kufanele zibe nesici sokuba nesikhumba esinesikhumba esomile, esomile, esine-keratinized nesiwugqinsi.

Esikhundleni salokho, izilwane ezihuquzelayo ziyiqembu langaphakathi phakathi kwabakhasa, lapho kuvulwa khona imikhakha ehlukene: ingxenye ebalulekile yezilwane ezihuquzelayo inemilenze emine yemisipha nomsila osiza ukulinganisela, lezi yizilwane ezihuquzelayo ezingakhambi njalo kodwa kungenzeka, lapho bedinga ukuhamba ngejubane eliphakeme, ukukhuphuka ngemilenze yabo futhi baphakamise ngokuphelele isisu sabo emhlabathini.

Olunye uhlobo lwezilwane ezihuquzelayo, phakathi kwalo inyoka njengesibonelo esicacile, ayinazitho zomzimba futhi ingakhasa kuphela. Lezi zilwane kumele zibe namandla okuqina futhi zikwazi ukujwayela imvelo, ukuze zikwazi ukumelana namandla okuhamba ngaleyo ndlela kuphela.

Ukunyakaza okungenamgogodla kokuhamba

I- ukufuduka kwamanye ama-invertebrate Njengezikelemu, kusekelwe eqinisweni lokuthi ingxenye ethile yomzimba iyavuvukala ngokugijimisa umzimba emuva naphambili: lokhu kuvuvukala kukhiqizwa ngesikhwama semisipha esinganweba noma sivumelane. Lesi sigaba sokunyakaza sibizwa nge-peristaltic, futhi kujwayelekile kuwo wonke ama-annelids.

Icala elithile lelo iminenke, okwakucatshangwa ukuthi isikhathi eside ngenxa yesilayidi esinayo, iyakwazi ukudala izindlela ezihamba phambili zokuhamba. Ngokuphambene nalokho, uphenyo lwakamuva luqinisekisa ukuthi ukufuduswa kweminenke kunikezwa yiminyakazo ye-peristaltic yemisipha eyenzeka ngaphakathi komzimba.

Iminenke ihamba phambili ngaphandle kokusebenzisa amandla kumaphuzu athile, kepha ngokusabalalisa amandla aphansi endaweni enkulu kakhulu. Into yokunamathisela, ngakho-ke, iyivumela ukuthi ihambe kalula, kepha akuyona impande yekhono lokuhamba enikezwa yisimo sayo njenge-annelid.

Nalu uhlu lwezilwane ezikhasayo ezibandakanya izilwane ezihuquzelayo nama-annelids.
