Babukeka kanjani oshaka abakhulu abamhlophe?
Ushaka omkhulu omhlophe ungomunye walabo okuthiwa oshaka bangempela. Ngoba unomumo ojwayelekile woshaka: Umzimba wakhe umise okwe-torpedo, okuwenza umbhukudi ophelele. Ikhala liyikona futhi licijile. I-caudal fin emise okwesikela, i-dorsal fin engunxantathu, kanye namaphiko amade e-pectoral, anombala omnyama emaphethelweni, akungabazeki. Isisu simhlophe, ingemuva siluhlaza kuya kompunga-nsumpa.
Ngokwesilinganiso, ushaka omkhulu omhlophe ungamamitha angu-4.5 kuya ku-6.5 ubude, abanye baze bafike kumamitha ayisikhombisa. Izibonelo ezincane zinesisindo esingamakhilogremu angu-700, esikhulu kunazo zonke esifika ku-2000 kilograms. Umlomo ubanzi futhi uyindilinga kancane, amazinyo awunxantathu. Amehlo amakhulu kanye nemifantu emikhulu yegill kuyamangaza.
Bahlala kuphi oshaka abakhulu abamhlophe?
Ushaka omkhulu omhlophe utholakala cishe kuzo zonke izilwandle, ikakhulukazi ezindaweni ezipholile. Kodwa-ke, iphinde ibonakale olwandle olushisayo nolwandle olushisayo, lapho ngokuvamile itholakala ebusika kuphela. Kuvame kakhulu ukubona ngasogwini lwaseNingizimu Afrika, e-Australia, eNew Zealand naseCalifornia.Ushaka omkhulu omhlophe uzingela emanzini angashoni eduze nosebe lapho kuhlala khona izimvu zamanzi eziningi namabhubesi olwandle. Uma kungenjalo, ngokuvamile uhlala ngaphezu kwamashalofu ezwekazi nasemithambekeni yawo. Lezi yizindawo ezisolwandle lapho imiphetho yamazwekazi yehlela khona ngokujula olwandle.
Ushaka omkhulu omhlophe ubhukuda ngokuqondile emanzini nasekujuleni okungafika kumamitha ayi-1300. Kwesinye isikhathi uhamba amabanga amade kakhulu.
Oshaka abakhulu abamhlophe baba neminyaka emingaki?
Akwaziwa ukuthi oshaka abakhulu abamhlophe bangafinyelela iminyaka emingaki. Nokho, abacwaningi basola ukuthi bangabandala njengabantu. Iminyaka kashaka inganqunywa cishe ngosayizi womzimba wakhe: ushaka omkhulu omhlophe ongamamitha amahlanu kuya kwayisithupha ubude uphakathi kweminyaka engama-21 kuya kwengama-23 ubudala.

Baphila kanjani oshaka abakhulu?
Ushaka omkhulu omhlophe ungumzingeli ophelele. Ngoba unesitho esikhethekile emakhaleni akhe: okuthiwa ama-ampoules e-Lorenzini. Lezi izimbobo ezigcwele i-gelatinous substance. Ngalokhu, ikwazi ukuzwa izizinda zikagesi zempango yayo ikude kakhulu. Amehlo nekhala kuthuthuke kangcono kakhulu kunabanye oshaka. Ngokwesibonelo, angabona nemibala futhi ezwe ngisho nephunga elincane kakhulu emanzini.
Ngaphezu kwalokho, inethiwekhi ekhethekile yemithambo yegazi inikeza amehlo nekhala ukuze basabele ngokushesha. Ukujikeleza kahle kwegazi kuyisizathu esenza ukuthi ushaka omhlophe abe nokushisa komzimba okwenyukile futhi awunagazi elibandayo futhi alincikile ekushiseni kwendawo ezungezile.
Izinga lokushisa lomzimba kashaka omkhulu omhlophe lihlala liyi-10 kuya ku-15 degrees Celsius ngaphezu kwezinga lokushisa lamanzi. Ngakolunye uhlangothi, lokhu kuyenza ikwazi ukubhukuda ngokushesha futhi, ngakolunye uhlangothi, ingahlala olwandle olubandayo. Izenzakalo ezifanayo zikhona kuphela kwabanye oshaka abakhulu naku-tuna enkulu noma i-swordfish.
Kuze kube muva nje, bekucatshangwa ukuthi ushaka omhlophe uyisizungu ngokuphelele. Manje sekuyaziwa ukuthi ziyizilwane zomphakathi futhi zivame ukwakha amaqembu amancane. Ngisho noma abantu abaningi besaba kakhulu ushaka omhlophe ngenxa yemibiko eyihaba:
Baningi kakhulu oshaka ababulawa abantu kunababulawa abantu abamhlophe abakhulu. Ngokuyisisekelo, abantu abayona ingxenye yohlelo lokudla ushaka omhlophe. Kodwa oshaka bayazwela emisindo futhi banelukuluku lokwazi.
Lapho kukhona okunyakazayo emanzini, oshaka babhukuda bebheke kulowo mthombo womsindo. Kungakho kwenzeka ukuthi zifune “ukuhlola” isilwane esingaba isisulu - esingaba ngumuntu - ngokulunywa ngokulinga. Nokho, ukuluma okukodwa okunjalo kulimaza kakhulu abantu futhi ngokuvamile kuyababulala.
Abangane nezitha zikashaka omkhulu omhlophe
Ngisho noma ushaka omkhulu omhlophe uyinhlanzi enkulu edla ezinye, kunezilwane ezidla ezinye ezinkulu olwandle. Imikhomo ebulalayo mikhulu kakhulu futhi iyizilwane ezinekhono kangangokuthi ingaba usongo koshaka abakhulu abamhlophe. Nokho, akuvamile ukuba i-pod of killer whales ibulale ushaka omkhulu omhlophe. Isitha esikhulu sikashaka omhlophe yindoda. Uzingela le nhlanzi engavamile, nakuba ivikelekile.
Bazalana kanjani oshaka abakhulu?
Akukho okuningi okwaziwayo mayelana nokuzalana koshaka abakhulu abamhlophe. Ziyi-viviparous, okusho ukuthi intsha ikhula esibelethweni. Kodwa-ke, akwaziwa kahle ukuthi abesifazane bakhulelwe isikhathi esingakanani. Abacwaningi bacabanga ukuthi kuthatha izinyanga eziyishumi nambili ukuthi oshaka abancane bazalwe. Khona-ke sezivele zingafika ku-150 amasentimitha ubude.
Akwaziwa futhi ukuthi insikazi ingaba namawundlu amangaki ngesikhathi esisodwa. Izilwane ezinabantwana abayisishiyagalolunye sezike zabonwa. Kukhona into eyinqaba kushaka omkhulu omhlophe: kwenzeka ukuthi izingane zilwe zodwa esibelethweni sikanina.
