Izilwanyana ezirhubuluzayo

Umxholo

• Ukufuduswa kwezirhubuluzi
• Intshukumo yokukhasa engenamqolo
• Imizekelo yezilwanyana ezirhubuluzayo

Inkcazo yesichazi 'erhubuluzayo ' inobudlelwane ngqo nelizwi 'gungxula ', kwaye xa lisetyenziswa kwizilwanyana lithetha ngezo zihamba emhlabeni, oko kukuthi, kuwo.

Nangona abanye besebenzisa umxholo ukuthetha nokuthetha ngeentaka ezibhabhela phantsi okanye kwinqanaba lomhlaba, eyona nkcazo yezilwanyana zirhubuluzayo yile izilwanyana ezirhubuluzayo. Inkcazo ikwanwenwela nakwintsimi yebhotani, kuba izityalo ezirhubuluzayo zezolule isiqu sazo emhlabeni.

Ukufuduswa kwezirhubuluzi

Izilwanyana ezirhubuluzayo zihlala zinxulunyaniswa neqela lezirhubuluzi, ezinesiseko sokudonsa imizimba, isenzi esinika igama laso kudidi lwezirhubuluzi. Nangona kunjalo ayizizo zonke izirhubuluzi ezirhubuluzayoKuba izilwanyana ezininzi zihamba ngaphandle kweli qela: ukongeza ekurhubuluzeni, izilwanyana ezirhubuluzayo kufuneka zibe neempawu zokuba nesikhumba esomileyo, esomileyo, esenziwe ngekeratini kunye nesingqindilili.

Endaweni yokuba, izirhubuluzi ziliqela elingaphakathi kwabarhubuluzi, ngaphakathi apho kuthi kuvulwe iindidi ezahlukeneyo: icandelo elibalulekileyo lezirhubuluzi linemilenze emine yemisipha kunye nomsila onceda ukulingana, ezi zizirhubuluzi ezingahambi ngalo lonke ixesha kodwa ukubakho, xa bafuna ukuhamba ngesantya esiphezulu, ukunyuka ngemilenze yabo kunye nokuphakamisa ngokupheleleyo isisu sabo emhlabeni.

Olunye uhlobo lwesirhubuluzi, phakathi kwalo inyoka njengomzekelo ocacileyo, ayinamalungu kwaye inokukhasa kuphela. Ezi zilwanyana kufuneka zibe nesantya esomeleleyo kunye nesakhono esikhulu sokuziqhelanisa nokusingqongileyo, ukuze zikwazi ukumelana nokukwazi ukuhamba ngaloo ndlela.

Intshukumo yokukhasa engenamqolo

Inkqubo ye- ukufuduka kwezinye izilwanyana ezingenamqolo Njengeentshulube, isekwe kwinto yokuba ilungu lomzimba liyadumba ngokuqhuba umzimba ubuye umva: oku kudumba kuveliswa yingxowa yemisipha enokwanda okanye ityikitye. Eli klasi leentshukumo libizwa ngokuba yi-peristaltic, kwaye liqhelekile kuzo zonke ii-annelids.

Ityala elithile lelo isineyile, apho ixesha elide bekucingelwa ukuba ngenxa yesilayidi esinayo, iyakwazi ukuvelisa iindlela ezifanelekileyo zokuhamba. Ngokuchasene noko, uphando lwakutshanje luqinisekisa ukuba ukufuduswa kweenkumba kunikezelwa yimisipha ye-peristaltic eyenzeka ngaphakathi emzimbeni.

Imigibe iqhubela phambili ngaphandle kokunyanzelisa amanqaku athile, kodwa endaweni yokuhambisa amandla asezantsi kwindawo enkulu kakhulu. Isixhobo sokuncamathela, ke, siyivumela ukuba ihambe ngokulula, kodwa ayisiyiyo ingcambu yesakhono sokuhamba esinikwa yimeko yaso njenge-annelid.

Nalu uluhlu lwezilwanyana ezirhubuluzayo kubandakanya izilwanyana ezirhubuluzayo kunye neel annelids.
