Njengoko besikhankanyile amaxesha amaninzi kule, ulwandle yinto engayekiyo ukusothusa. Singazifumana iintlobo zaselwandle ezizodwa kangangokuba asinakuze sicinge ukuba zinokubakho. Le yimeko yekati yokrebe. Nangona ayisiyondawo ebonakalayo ukuba inkulu, inokusinika umbono wokuba siyibone.

Ayilulo uhlobo lokrebe olunobukhulu obukhulu nangona zikhona ezinye ezinokulinganisa ukuya kuthi ga kwi-4 yeemitha. Into eqhelekileyo kukuba bafike ukulinganisa i-1.20 yeemitha. Umhlathi wayo womelele njengoko unamazinyo agobileyo kwaye ubuncinci ngokomlinganiso. Iwasebenzisa ikakhulu ukuze akwazi ukutya iimollusks, ngamanye amaxesha amancinci kwaye ezinye izilwanyana ezinje ngoononkala.
Indawo yekati yookrebe kunye noluhlu
Lo krebe uyaqhelana nalo naluphi na uhlobo lwamanzi ashushu okanye akweleenjiko, enza ukuba ukusasazwa kwawo kubanzi ngokubanzi. Kukho iintlobo ezahlukeneyo ngokuxhomekeke kwindawo esikuyo. Kukho ezinye eziguqulwe kufutshane namazwekazi aseAsia, eAfrika naseMelika.
Ookrebe bekati baneentloni kakhulu ukudibana nabo ngobuqu kunokuba nzima. Ubungakanani bayo kunye nobukhulu bayo benza ukuba kungabikho lula ukubamba, yiyo loo nto iba luhlobo olunqabileyo. Ngokuphathelele kwindalo, ezinye iintlobo zolu sapho bakhetha ukudada ezinzulwini ezifikelela kwiimitha ezili-100. Nangona kunjalo, kukho abanye abakhetha amanzi aphantsi.
Ikhetha amanzi ashushu kunye nalawo ashushu kuba kukho ukutya okubonelela ngezakha mzimba ezaneleyo zokuphuhlisa nokuzala. Singazifumana iisampulu zekrebe kuLwandlekazi lweAtlantic, ngakumbi kwezona ndawo zinzulu phakathi kweNorway kunye neIvory Coast. Ukuze ukwazi ukuzingela ezi zilwanyana kwaye bathabathe imifanekiso, kuya kufuneka ube ngononophelo olukhulu kuba azibonakali. Banendlela yokuziphatha eneentloni kwaye, ukongeza kubungakanani babo obuncinci, kunzima ukubamba.
Ingadada kubunzulu obufikelela kwiimitha ezingama-2000.
Ukutya
Le krebe itya ikakhulu ukutya kwezilwanyana ezincinci ezingenamqolo ezifumaneka kubunzulu bolwandle. Ukutya kwayo kukutya kwaye kufuna isixa esikhulu senyama. Inokungenisa, nangona ubuninzi buncinci, ezinye zinezithuba kwinto elula yokuba nakho ukubandakanya ezinye zezondlo ekufuneka zikwazi ukuziphuhlisa phantsi kweemeko.
Ngokutsho kweengcali zebhayoloji zaselwandle eziphethe uphando ngezinto ezityiwa ngookrebe, zithi lo krebe utya ezinye iintlanzi ezincinci ngenxa yobukhulu bakhe. Lo ngowona tshintsho luphambili oluyithintelayo ekubeni ikwazi ukuzingela amanye amaxhoba amakhulu. Ngokuchasene noko, oko akuthethi ukuba ukutya kwabo kunqabile kuba kukho iindidi ezininzi de peces ezincinci kunye nezilwanyana ezingenamqolo kwiindawo apho bahlala khona aba krebe.

Ukuzaliswa kwakhona kwekrebe
Lo krebe une uhlobo lwayo lwe-oviparous lokuvelisa kwakhona. Oku kubandakanya ukubeka amaqanda kwindawo ekhuselekileyo kwaye nje ukuba ookrebe abancinci baqandusele, bazimele ngaphandle kwabazali babo.

Umthamo we ukwazi ukuphinda kabini okanye ukuphindaphinda kathathu ubungakanani bakho ukuba uziva usoyikiswa Le yenye yezona zinto zimangalisayo kunye nendlela yokuphila enomdla. Xa esiba noloyiko kuxa ekwazile ukuphinda kathathu ubungakanani bakhe ukuphuma engxakini. Oku kufezekiswa kusetyenziswa umatshini onalo lonke udidi lwalo krebe ovumela isisu sonke ukuba sithathe imilomo emikhulu yamanzi ukwandisa ubungakanani bayo ngokubanzi.
Umahluko phakathi kwe-dogfish kunye ne-cat shark
Ukwahlula iintlobo ezimbini ezifanayo, ezifana ne-dogfish kunye ne-cat shark, kufuneka uyazi inxenye yeempawu zazo zangaphandle. Masibone umohluko ophambili:
