<prompt> Fingqa isihloko: Kunikeza incazelo entsha emshweni othi ukuhlaselwa ushaka. Nakuba iningi labantu lizazi izithombe zezimfene eziqothwa ngobudlova emanzini ziqotshwe ngemihlathi yoshaka, kubonakala sengathi abanye baziphindiselela ezilwaneni zasolwandle ezidla ezinye. Ososayensi baye babika ngezigameko eziningana zezimfene ezihlasela oshaka abaluhlaza okwesibhakabhaka ogwini lwaseNingizimu Afrika. Skrolela phansi ukuze ubone ividiyo. Ososayensi baye babika ngezigameko eziningana zezimfene ezihlasela oshaka abaluhlaza okwesibhakabhaka futhi zidle izibilini zabo ogwini lwaseNingizimu Afrika. Lokhu kuziphatha kuye kwashiya izazi zezinto eziphilayo zasolwandle zididekile ngokuthi kungani ama-seal ephendukela ekuhlaseleni oshaka abanjenge-torpedo. Ama - seal, ngokuvamile adla oshaka abamhlophe abakhulu, aye abonakala ehlasela futhi ebulala oshaka abaluhlaza okwesibhakabhaka, edla izibilini zabo ngaphambi kokushiya isidumbu. Abacukuzi babika nokuthi baye babona ama - seal enoboya ehlasela ezinye izinhlobo zoshaka nama - ray. Lokhu kuziphatha kuye kwashiya izazi zesayensi yezinto eziphilayo zasolwandle zingaqondi ukuthi kungani ama - seal, ngokuvamile azingela izinhlanzi ezincane, aye aphendukela ekuhlaseleni oshaka abanjenge - torpedo. Oshaka abaluhlaza okwesibhakabhaka banobukhulu obucishe bufane nobezimpungushe futhi kucatshangwa ukuthi lesi yisikhathi sokuqala ukuba kubonwe impungushe idla isilwane esikhulu kangaka. Yaqala ukubonwa umthwebuli wezithombe zasolwandle uChris Fallows, ophethe isikebhe sokuntywila esiseKapa eNingizimu Afrika. UDkt. Neil Hammerschlaf, isazi sesayensi yezinto eziphilayo zasolwandle eSikoleni SaseRosenstiel Sezesayensi Yezasolwandle Nezemvelo, owahlanganyela kulolu cwaningo, wathi kubonakala sengathi ama-seal adla amathumbu oshaka njengoba equkethe amandla amaningi. Oshaka abaluhlaza okwesibhakabhaka banobukhulu obucishe bufane nobezimpungushe futhi kucatshangwa ukuthi lesi yisikhathi sokuqala ukuba kubonwe impungushe idla isilwane esikhulu kangaka. Isazi esithile sathi kunemibiko embalwa kakhulu yezinhlanzi ezinemilenze emibili, noma ama - seal, ezidla oshaka ngokujwayelekile, futhi kuzo zonke lezi zimo kwakuhileleke oshaka abancane. Ushaka oluhlaza okwesibhakabhaka, njengalowo ongenhla, ungomunye wezilwane zasolwandle ezidla ezinye eziphambili ezinomzimba omuhle nomlomo ogcwele amazinyo.  <response>: Ososayensi babika ukuthi ama-cape fur seal aye ahlasela futhi abulala oshaka abaluhlaza okwesibhakabhaka. Lokhu kuziphatha okungajwayelekile kwabonwa ababhukudi ngasogwini lwaseNingizimu Afrika. Ama-seal ngokwawo avame ukuzingelwa futhi abulawe oshaka abamhlophe abakhulu. Oshaka abaluhlaza okwesibhakabhaka banobukhulu obucishe bufane nobomkhomo kodwa badla kakhulu izinhlanzi ezincane. Ama-seal abonakala ehlasela oshaka bese edla izibilini zabo kuphela. Lokhu kucatshangwa ukuthi kuyingxenye yamandla amaningi kakhulu koshaka ekubhekaneni ne-seal.
