Iintlobo zeekrebe kwiMeditera
KwiMeditera, kukho iindidi ezingaphezu kwama-40 zookrebe eziye zachongwa. Ezinye zezona ntlobo zixhaphakileyo kunye nezaziwayo ezinokufumaneka kula manzi ziquka:
- Ukrebe omhlophe (ICarcharodon carcharias)
- Ukrebe oluhlaza (I-Prionace glauca)
- Hammerhead shark (Sphyrnidae)
- ingelosi shark (i-squatina squatina)
- Bull shark (taurus carcharias)
Nganye kwezi ntlobo zineempawu ezizodwa kunye nokukhethwa kwendawo yokuhlala, eyenza ukuba zilungele kwaye zihluke ngaphakathi kwe-ecosystem yoLwandle lweMeditera.
Iindawo ezihlala ookrebe kwiMeditera
Ookrebe kwiMeditera banokufumaneka kwiindawo ezahlukeneyo, ukusuka kumanzi angekho nzulu kunye nonxweme ukuya kwiindawo ezinzulu kunye ne-pelagic. Ukukhethwa kwendawo yokuhlala kuyahluka ngokuxhomekeke kuhlobo kunye nokuziphatha kwayo.
El Ukrebe omhlophe Ifumaneka zombini kumanzi onxweme kunye nolwandle oluvulekileyo, rhoqo kufuphi ne-seal colonies, enye yezinto zayo eziphambili. Kwelinye icala, i ukrebe oluhlaza ubukhulu becala i-pelagic, okuthetha ukuba ihlala emanzini avulekileyo kude nonxweme nakwimimandla engaselunxwemeni.
El I-hammerhead ukrebe Ngokuqhelekileyo ifumaneka kwiindawo ezishushu kunye neendawo ezitshisayo, kwaye inokubonwa kufuphi nomphezulu wolwandle, kunye nobunzulu obufikelela kwi-1100 yeemitha. Yena ingelosi shark Luhlobo lwe-benthic oluhlala emazantsi olwandle, apho luzingcwabela esantini ukuze luzingele amaxhoba alo, njengentlanzi kunye neecrustaceans. Ekugqibeleni, i inkunzi ukrebe Ifumaneka ikakhulu kumanzi angekho nzulu elunxwemeni nakwishelufu yelizwekazi.
Ukuziphatha kunye nokondla
Ukuziphatha kunye nokutya kookrebe kwiMeditera kuyahluka ngokuxhomekeka kwiimpawu ezithile zohlobo ngalunye.
El Ukrebe omhlophe Lirhamncwa elinobuchule, litya kakhulu izilwanyana zaselwandle, njengeentini, amahlengesi, neeporpoise. Basenokutya iintlanzi namafudo olwandle. Kwelinye icala, ookrebe abaluhlaza batya iindidi ngeendidi zeentlanzi nee-cephalopods, ezifana nesquid.
Los I-hammerhead ukrebe banokutya okwahluka-hlukeneyo, okunokubandakanya iintlanzi ezinamathambo, iicrustaceans, i-cephalopods, kunye nabanye ookrebe. Ookrebe beengelosi, njengoko besitshilo ngaphambili, batya amaxhoba e-benthic afana neentlanzi kunye neecrustaceans. Ekugqibeleni, i ookrebe benkomo zingamarhamncwa angenelelayo atya iindidi ezininzi zezinto eziphilayo, ukusuka kwiicrustaceans kunye neentlanzi ezinamathambo ukuya kwizilwanyana zaselwandle.
Iimfuno malunga nookrebe beMeditera
Kukho inani elikhulu leenyani ezinomdla kunye nezinomdla malunga nookrebe abahlala kuLwandle lweMeditera.
1. I ookrebe abamhlophe kwiMeditera bakhuselwe zizivumelwano zamazwe ngamazwe ezithintela ukuloba okanye urhwebo lwabo.
2. Nangona kukho inkolelo ethandwayo yokuba ookrebe bayingozi ebantwini, uhlaselo lookrebe kwiMeditera lunqabile. Ngapha koko, ngaphantsi kwe-2% yalo lonke uhlaselo lukakrebe emhlabeni lwenzeka apha.
3 I ingelosi shark Ithathwa njengenye yeekrebe ezinqabileyo kwihlabathi kwaye idweliswe njengabaseMngciphekweni ngokuBalulekileyo kuLuhlu oluBomvu lweManyano yeZizwe ngeZizwe yoLondolozo lweNdalo (IUCN).
Ukugcinwa kookrebe kwiMeditera
Ulondolozo lweentlobo zookrebe kuLwandle lweMeditera lubalulekile ukugcina ulungelelwano lwendalo yaselwandle. Phakathi kwezona zoyikiso ziphambili ezijongene nazo ezi zilwanyana kukuloba ngokugqithisileyo, ukuloba ngempazamo okanye ukubanjiswa ngengozi, kunye nokonakaliswa kweendawo zokuhlala.
Ukuqinisekisa ukuphila kwezi ntlobo zezilwanyana, kubalulekile ukuba kuphunyezwe amanyathelo olondolozo afana nokukhuselwa kweendawo zokuhlala ezibalulekileyo, ulawulo lokuloba nokwazisa uluntu ngokubaluleka nexabiso lokrebe kuLwandle lweMeditera.
Ukuqukumbela, ookrebe beMeditera banomdla kwaye iintlobo ezahlukeneyo zezilwanyana ezidlala indima ebalulekileyo kwimpilo yendalo yaselwandle. Ukwazi ngakumbi ngebhayoloji yabo, ukuziphatha kunye nokudiliza iintsomi ezibangqongileyo, sinokuba negalelo kulondolozo lwabo kwaye siqinisekise ukusinda kwabo kula manzi amangalisayo.
