Ushaka ompunga omhlophe ojiwe ngomhlophe (Carcharhinus albimarginatus) ungowoshaka abakhulu kakhulu, i-oda le-carchinoids, inhlanzi yeklasikhi eyindilinga.
Ukusatshalaliswa koshaka we-whitetip grey.
Ushaka wempunga omhlophe omhlophe utholakala ikakhulu ezindaweni ezishisayo zasentshonalanga ye-Indian Ocean, kufaka phakathi uLwandle Olubomvu namanzi ase-Afrika asempumalanga. Iyasakazeka nasentshonalanga yePacific. Kutholakala kusukela eningizimu yeJapan kuye enyakatho ye-Australia, kufaka phakathi iTaiwan, iPhilippines kanye neSolomon Islands. Ihlala olwandle olusempumalanga yePacific ukusuka eMexico engezansi kweCalifornia kuye eColumbia.
Indawo yokuhlala i-grey whitetip shark.
Ushaka omhlophe ophelile okumhlophe uyinhlobo ye-pelagic ehlala kuzo zombili izindawo ezingasogwini naseshalofini emanzini asezindaweni ezishisayo. Imvamisa ifika emashalofini ezwekazi naseziqhingini, ekujuleni okungafika kumamitha ayi-800. Oshaka baphinde bazalele ngasogwini lwamakhorali nasezixhotsheni zamanzi, naseziqhingini ezingasogwini lolwandle. Amajuba abhukuda emanzini angajulile ukugwema ukudliwa.
Izimpawu zangaphandle zikampunga we-whitetip shark.
Ushaka we-whitetip shark unomzimba omncane, ohlanjululwe ngomlomo omude oyindilinga. Isiphetho se-caudal asymmetrical, ne-lobe enkulu ephezulu. Ngaphezu kwalokho, kukhona amaphiko amabili omgogodla. Owokuqala mkhulu futhi ukhombe, futhi ugijima usondele endaweni efanayo yomzimba njengamaphiko wepectoral. Umphetho wesibili ngemuva mncane futhi ugijima ngokufana nowokugcina wendunu. Kukhona igebe phakathi kwamaphiko emhlane. Amaphiko e-pectoral made, amise okweqanda, futhi acijile njengamaphiko ezinye izinhlobo zoshaka abampunga.
I-whitetip shark empunga inamazinyo ezinsaha emhlathini ongaphansi nongaphezulu. Umbala ojwayelekile womzimba umpunga omnyama noma onsundu ngaphezulu; ama-scuffs amhlophe ayabonakala ngezansi. Wonke amaphiko anamathiphu amhlophe eceleni komugqa ongemuva; kuyisici sokuxilonga esihlukanisa laba oshaka ezihlotsheni zabo eziseduze kakhulu: oshaka abampunga kanye noshaka we-whitetip reef.
Oshaka abamhlophe abampunga bakhula bafike kumamitha amathathu ubude (ngokwesilinganiso samamitha amabili kuya kwangu-2,5) kanti abesifazane bavame ukuba bakhulu kunabesilisa. Isisindo esiqoshwe kakhulu soshark we-whitetip grey ngu-162.2 kg. Kunamabhangqa amahlanu ama-gill slits. Amazinyo ahlelwe ngemigqa eyi-12-14 ohlangothini ngalunye lwemihlathi yomibili. Emhlathini ongenhla, zinxantathu ezimise okwezinti ezingalingani esisekelweni bese zishaywe ngamadevu ekugcineni. Amazinyo aphansi ahlukaniswa yimisipha emincane.
Ukuzaliswa koshaka we-whitetip grey.
UGrey Whitetip Sharks uyalingana phakathi nezinyanga zasehlobo. Abesilisa bahlanganiswe ngababili, izakhiwo zokuzala ezilinganayo ezaziwa ngokuthi imikhaza esemaphethelweni amaphiko azo. Abesilisa bayaluma futhi baphakamise imisila yabesifazane ngenkathi yenqubo yokukhwelwa ukuze kukhululwe isidoda ku-cloaca yowesifazane ukuze kukhulelwe kwangaphakathi. Oshaka abampunga o-whitetip bayi-viviparous.
Imibungu iyakhula emzimbeni kamama, idla nge-placenta unyaka owodwa. Oshaka bazalwa ngobuningi kusuka ku-1 kuye ku-11 futhi bafana noshaka abancane abadala, ubude babo bungamasentimitha angama-63-68. Bahlala ezindaweni ezingajulile zemifula bese bangena emanzini ajulile lapho bekhula. Abesilisa abasebancane bayakwazi ukuzala ngobude obungamamitha ayi-1.6-1.9, abesifazane bakhule bafike kumamitha ayi-1.6-1.9. Ukunakekela inzalo yalolu hlobo akubonwa. Ayikho imininingwane ethile ngempilo yoshaka abampunga emvelweni. Kodwa-ke, izinhlobo ezihlobene kakhulu zingaphila kuze kube yiminyaka engama-25.
Ukuziphatha kwe-whitetip shark empunga.
Oshaka abampunga omhlophe ngokuvamile bayizinhlanzi ezihlala zodwa, futhi ukusatshalaliswa kwabo kuhlukaniswa, ngaphandle kokuxhumana okusondelene kwabantu.
Yize bengaba nolaka lapho besongelwa, abukho ubufakazi bokuthi bahlala endaweni ethile.
Oshaka abampunga beWhitetip babonisa isimilo esinolaka, okuphazamisa izilwane ezinkulu. Bahambisa amaphiko abo omsila nomsila, benze ukugoba okubukhali komzimba ngaphandle kokunyakaza, "bathuthumele" ngomzimba wabo wonke futhi bavule umlomo kakhulu, bese bezama ukubhukuda ngokushesha basuke esitheni. Uma usongo luqhubeka, oshaka, njengomthetho, abalindeli ukuhlaselwa, kepha zama ngokushesha ukuphuma. Yize kungeyona indawo, oshaka abamhlophe bahlasela amalungu ohlobo lwabo, yingakho bavame ukuthwala izibazi zempi emizimbeni yabo.
Kubantu, lolu hlobo lukashaka lubhekwa njengengozi, yize isibalo sabantu abalunyiwe asisikhulu kakhulu uma siqhathaniswa nezinye izinhlobo zikashaka ezinkulu.
Amehlo we-whitetip grey sharks aguqulelwe umbono emanzini anodaka, lesi sici sibavumela ukuthi babone izikhathi eziphindwe kalishumi kunokubona komuntu. Ngosizo lwemigqa eseceleni namangqamuzana ezinzwa, oshaka babona ukudlidlizela emanzini futhi babone ushintsho emikhakheni kagesi ebaxwayisa ngabangaba izisulu noma izidlakela. Banokuzwa okuthuthukile futhi umuzwa onamandla wokuhogela ubavumela ukuthi bathole inani elincane legazi kumthamo omkhulu wamanzi.
Ukudla ushaka we-whitetip grey
Oshaka abampunga abampunga yizilwane ezidla ezinye futhi badla izinhlanzi ze-benthic nezinambuzane zasemanzini ezihlala ekujuleni okuphakathi: i-spiny bonito, izinkozi ezijwayelekile ezinamabala, ama-wrass, i-tuna, i-mackerel, kanye nezinhlobo zomndeni iMykphytaceae, i-gempilaceae, i-albuloids, usawoti, ama-squid amancane, oshaka, octopus. Banolaka kakhulu ngesikhathi sokuphakelwa kunezinye izinhlobo eziningi zikashaka futhi bayashibilika bezungeza ukudla lapho behlaselwa.
Indima ye-ecosystem ye-grey whitetip shark.
Oshaka abampunga abampunga benza njengezilwane ezidla imvelo futhi bavame ukubusa izinhlobo zikashaka ezinjengeGalapagos kanye ne-blacktip shark. Ezinye izinhlanzi ezinkulu zingazingela izingane. Ama-crustaceans e-Ectoparasitic akhona esikhunjeni soshaka. Ngakho-ke, zilandelwa izinhlanzi ezilawulwayo kanye ne-rainbow mackerel, ezibhukuda zisondele kakhulu kuzo bese zikha izimuncagazi zesikhumba.
Okusho umuntu.
Kuyadotshwa oshaka abampunga. Inyama, amazinyo, nemihlathi yabo kuyathengiswa, kanti amaphiko abo, isikhumba, kanye noqwanga kuthunyelwa kwamanye amazwe ukuze kwenziwe imithi nezikhumbuzo. Inyama kashaka isetshenziselwa ukudla, futhi izitho zomzimba zingumthombo wezinto ezibalulekile zokwenziwa kwezinto ezahlukahlukene zasendlini.
Yize kungakaze kube nokuhlaselwa okurekhodwe koshaka we-grey whitetip kubantu emhlabeni wonke, laba oshaka bangaba yingozi kubantu abadilika eduze kwezinhlanzi.
Isimo sokongiwa koshaka we-whitetip grey.
Ushaka wempunga omhlophe ompunga ubhekwa njengosengozini yi-International Union for Conservation of Nature and Natural Resources. Ukwehla ikakhulu kubangelwa ingcindezi yokudoba ehlotshaniswa nezindawo zokudoba ze-pelagic nezasolwandle (zombili ziyasebenza futhi zingenzi lutho, lapho oshaka bebanjwa ngamanetha njenge-by-catch), kuhlangene nokukhula kancane kwalezi zinhlobo nokuzala okuphansi.
