Ukutya ngokweentlobo zoshaka
Ookrebe abangoo-generalists xa kuziwa ekutyeni kwabo. Kukho malunga nama-400 eentlobo ezahlukeneyo zookrebe, yaye ngamnye kubo ubonakala eqhelana nokutya uhlobo oluthile lokutya. Ezinye iintlobo zidla kakhulu iintlanzi ezinamathambo, ngelixa ezinye zinokutya izilwanyana zaselwandle kunye nabanye ookrebe.
Ukrebe omhlophe, umzekelo, uyaziwa ngokutya izitywina kunye neengonyama zolwandle, ngaphezu koluhlu olubanzi lweentlanzi ezinamathambo kunye ne-cartilaginous. Kwelinye icala, ookrebe iHammerhead batya ukutya okuquka imitha nezinye iintlanzi eziselwandle.
ukutya okungenelelayo
Ookrebe badla ngokuthatha amathuba xa kuthethwa ngokutyisa. Oku kuthetha ukuba banobuchule kakhulu ekufumaneni nasekubambeni naliphi na ixhoba elikwindawo yabo ekufutshane, nokuba ayikuko ukutya abakuthandayo.
NgokomzekeloUkuba iqela leentlanzi ezincinci liqubha kufutshane nokrebe, kusenokwenzeka ukuba ukrebe uya kuxhakamfula eli thuba aze atye intlanzi ngaphandle kokuchitha amandla amaninzi ekutya. Oku kuziphatha kubavumela ukuba bagcine izixhobo zabo kwaye bahlale bekulungele ukujongana namathuba angcono okutya anokuthi avele.
ukutyisa isihluzi
Ngaphandle kokwaziwa njengezilwanyana ezidla inyama, kukho iintlobo zokrebe eziye zamkela indlela engaqhelekanga yokondla ebizwa ngokuba kukutyisa izihluzi. Ookrebe iWhale sharks nebasking sharks yimizekelo ephawulekayo yookrebe abondla ngolu hlobo.
Ezi ntlobo zookrebe, ngaphandle kobukhulu bazo kunye namandla azo okuzingela, ziye zavela ukuze zitye izixa ezikhulu zeplankton kunye nezilwanyana ezincinci zaselwandle ngokuhluza amanzi. Aba krebe bahamba kancinane emanzini bevule imilomo, befaka amanzi amaninzi ngeeseli zabo, apho bahluza kwaye babambe iiplankton ukuze bafumane ukutya.
ubuzim phakathi kookrebe
Nangona kusenokubonakala kumangalisa, kwezinye iimeko, ookrebe banokuba ngamazim abantu. Oku kudla ngokwenzeka xa inani lamaxhoba lisezantsi okanye xa ukrebe esenza impazamo ngelixa ezingela kwaye iqabane lakhe lithatha ithuba lemeko.
Kwiimeko ezininzi, olu hlobo lokutya abantu lubonakalisa amathuba ngakumbi kuneqhinga lokondla elinokwenyani. Ookrebe, njengoko sisazi, banokuba nethuba lokufumana ukutya, kwaye abayi kuliyeka ithuba lokuzalisa izisu zabo ukuba omnye wabazalwana babo uyawa.
I-Scavenger sharks kunye nokubaluleka kwabo kwi-ecosystem yolwandle
Ukongeza ekubeni ngabazingeli, ookrebe badla ngokusebenza indima ebalulekileyo njengabahlaseli kwi-ecosystem yaselwandle. Ngokutya iintsalela zezilwanyana ezifileyo, ookrebe banceda ukugcina ulungelelwano kwi-ikhosistim kwaye bathintele inkunkuma kunye nezinto ezibolayo zendalo ukuba zingafumba ezantsi kolwandle.
Iintlobo ezininzi zookrebe, kuquka nokrebe omhlophe owoyikekayo, azinangxaki ngokutya izilwanyana ezifileyo ukuba zimfumene endleleni yazo. Obu buchule bokutya ukutya osele bufile ngaphandle kokugula bubanika amathuba angakumbi okufumana ukutya ngaphandle kokuchitha amandla bekhangela nokubamba amaxhoba.
Isishwankathelo, ukutya kookrebe kunokwahluka kakhulu ngokuxhomekeke kwiintlobo kunye neemeko zokusingqongileyo abahlala kuzo. Nokuba zitya iintlanzi ezinamathambo, izilwanyana zaselwandle, iiplankton, okanye abanye ookrebe, ezi zidalwa zimangalisayo zihlala zifumana indlela yokuqinisekisa ukuba ziphila kwiilwandle ezininzi zehlabathi. Ngaphaya kwendima yazo njengezilwanyana ezizingelayo, zikwadlala indima ebalulekileyo ekugcineni ulungelelwano lwe-ikhosistim kunye nemekobume yaselwandle.
