Izilwanyana bufeze

izilwanyana bufeze abulale ngeenjongo ezimbini: ukukhusela kunye ukuhlasela. Kuba abathile, ukukhululwa ityhefu ezi ndlela scaring iintshaba kwaye akhusele ubomi bakho, kuba abanye - isixhobo ekuzingeleni kwimveliso yokutya.

izilwanyana Common enetyhefu phakathi iintlobo zezilo edyokhweni. Ukuba arthropods eziyityhefu (noonomadudwane, izigcawu, ezinye izinambuzane) kwaziwa ngokubanzi, lwezilwanyana ezinjalo kukho iindidi ezine kuphela. Le platypus Australia echidna, nokuphila eMelika, aardvark kunye nabanye shrews. Okubangel 'umdla kukuba, loo aardvark, enalo amathe enobuhlungu, uthambekele marhe yayo! Xa ukulwa ezithi zenzeke phakathi kwamalungu lweentlobo, aardvarks ezifayo buluma ezincinane abachasi bakhe. Kule meko kungenzeka ukuba ukugcina ubungakanani labemi kwinqanaba ngokwaneleyo, kwaye ngokubanzi, yintoni na isilwanyana ukuvelisa ityhefu, sabulala ngokwayo apho - enye iimfihlelo biology.

izilwanyana ezininzi enetyhefu ezingqondweni zabantu ningazi ziidemon. Ekubhekiselelwe kuyo wayesengozini loo mntu ukuba okunene akufane kube njalo. Ubuhlungu ngeekatsi kakhulu umntu kuphela sisilonda esidumbileyoesingaphakathi yobulali ukuba kwiiyure ezimbalwa udlula ngokukhuselekileyo. abhalwe ngokuthembekileyo omnye kuphela ityala lokufa kwabantu (oneminyaka esixhenxe ubudala) evela isilwanyana esinayo silume umntu skolopendry omkhulu. Inyeke waba entloko, mhlawumbi, le ukoyiswa yaba amaziko ebalulekileyo, ngaphandle unyango kakhulu emva kwexesha. Kungenjalo, le siganeko ingase isuswe kuluhlu lwe-manani ezibulalayo.

Yande Russia irhamba eyingozi kuphela entwasahlobo, xa ngenkuthalo ukuveza enzymes. Kwaye yonke enyakazelayo ukubuyisela ityhefu ithatha kakhulu elide ngaphezu kunoogxa ngakumzantsi wayo. Ngoko ke, ubuthi zethu irhamba osetyenzisiweyo ngokonga, wakhetha ukuhlasela moya, yaye abantu ingámluma kuphela self-yokuzikhusela. Ehlotyeni, ekwindla netyhefu irhamba amanqe yaye akukho nako ukwenza iqela mizwa ekhathazayo. izilwanyana ezinetyhefu zimelwe kwi kummandla welizwe lethu ayikho luninzi kakhulu. Kuphela kwimimandla ekumzantsi ukuba 'ukuqhayisa "iintlobo eyityhefu zezilo.

izilwanyana ezininzi zinetyhefu zehlabathi ziye-ebizwa ngokuba "letyhefu kwisixando sokwenziwa." Oku kuthetha ukuba akukho mfuneko yokuba amalungu ezikhethekileyo avelisa ityhefu. Ezinjalo, umzekelo, puffer intlanzi, equlethe tetrodotoxin zomzimba, nkqu hi mpimo lowutsongo ezibulalayo ngabantu. fugue zinetyhefu kakhulu kangangokuba indlela ekulungiselelwa ngayo ukutya kwayo bengasetyenziswa abapheki ngqo eqinisekisiweyo. EJapan, nangona ezi amanyathelo, nyaka ngamnye zenzeka ukufa eziliqela ngenxa yokusebenzisa le ntlanzi.

Izityalo eziyityhefu kunye nezilwanyana ngenxa becala - abameli zendawo kunye nobushushu. Le selectivity uhlobo ngenxa yokuba kwiqondo lobushushu eliphezulu izinga yokucolwa izinto eziphilayo kakhulu ngaphezulu kwe xa ephantsi abemi ekweleenjiko unako ukuhlawula Yinyongo yophuhliso eNtofontofo kunalawo kwi ezinezinga ephakathi yaye kubanda.
