Ihlengethwa lase-Atlantic elimhlophe emaceleni lingomunye wabamele umndeni wehlengethwa. Isici esihlukile salolu hlobo umugqa omhlophe noma okhanyayo ophuzi ohamba kuwo wonke umzimba wesilwane esincelisayo. Ngaphansi kwekhanda nomzimba kubuye kube nobisi olumhlophe noma olunombala ophuzi ngokukhanyayo. Umzimba osele unombala ompunga ngombala. Umzimba umise okwe-torpedo (unciphise ngasemsileni nasekhanda), amaphiko asemaceleni mancane futhi ayisicaba, kanti ingquza yomqolo imise okweqanda.
Ngokungafani namanye amalungu omndeni, impumulo yale dolphin ayibonakali kahle futhi ingamasentimitha ama-5 ubude.
Ihlengethwa lase-Atlantic elimhlophe emaceleni lincane kakhulu. Indoda endala ifinyelela ebangeni elingaphezu kwamamitha amabili nohhafu ubude, futhi inesisindo esifinyelela kuma-230 kilograms. Insikazi incane ngosayizi, ubude bayo bufinyelela kumamitha amabili nohhafu, futhi isisindo sayo sishintsha cishe sibe ngama-200 kilograms.
Amahlengethwa ase-Atlantic angamalungu ajabule kakhulu futhi adlalayo ezilwane zasolwandle. Lapho bekhulumisana, basebenzisa amaza omsindo futhi bayazwana ebangeni elibaluleke kakhulu.
Indawo yokuhlala
Kusuka egameni lale nhlobo yamahlengethwa, indawo eyinhloko yendawo abahlala kuyo iyacaca ngokushesha. Ihlengethwa emaceleni amhlophe likhaya loLwandle i-Atlantic (amazinga okushisa aphakathi nendawo nasenyakatho). Kusukela ogwini lweNhlonhlo YaseLabrador unqamula ogwini oluseningizimu yeGreenland uye eNhlonhlweni yaseScandinavia.
Lezi zinhlobo ziyivelakancane kakhulu emanzini aseRussia. Njengomthetho - uLwandle lwaseBarents neBaltic.
Ihlengethwa lase-Atlantic elimhlophe emaceleni luhlobo lwe-thermophilic kakhulu. Izinga lokushisa lamanzi abahlala kulo lisuka kuma-degree ayisihlanu kuya kwayishumi nanhlanu ngaphezu kweqanda.
Okudlayo
Ukudla okuyinhloko kwehlengethwa emaceleni amhlophe izinhlanzi ezisenyakatho ezinamafutha (i-herring ne-mackerel). Amahlengethwa nawo adla ama-cephalopod mollusks (ikakhulukazi ama-squid, i-octopus ne-cuttlefish).
Amahlengethwa azingela ngemihlambi. Imvamisa, amahlengethwa asebenzisa amabhamuza wemisindo nomoya ukuzungeza isikole sezinhlanzi bese adubula ngaso.
Isitha esikhulu semvelo sehlengethwa elimhlophe emaceleni ase-Atlantic ngabantu. Ukuthuthuka komnotho oLwandlekazi Lomhlaba futhi, ngenxa yalokho, ukungcoliswa kwalo kuholela ekwehleni kwenani lamahlengethwa. Futhi, imfundiso yamasosha iba imbangela yokufa kwalezi zilwane.
Futhi-ke, ukuzingelwa ngokungemthetho nokuzingela kubulala abantu abangaphezu kwe-1000 minyaka yonke. Ngasogwini lwaseNorway, imihlambi emikhulu yamahlengethwa iyaluswa futhi ivalelwe emachwebeni bese ibulawa.
Amaqiniso Athandekayo
- Ihlengethwa lase-Atlantic emaceleni amhlophe liyisilwane esincelisayo futhi inkonyane lihlala cishe iminyaka eyi-1.5. Futhi isikhathi sokukhulelwa siyizinyanga eziyishumi nanye. Ngaphambi kokubeletha, insikazi yenza abangane kude nomhlambi omkhulu.
- La mahlengethwa ahlala ngamaqembu amakhulu. Isibalo somhlambi sifinyelela kubantu abayi-60. Bathuthukise kakhulu ubudlelwane phakathi kweqembu.
- Isikhathi sokuphila iminyaka engama-25 ngokwesilinganiso.
- Amahlengethwa anezinhlangothi ezimhlophe ayizidalwa ezinobungane kakhulu. Bayakuthanda ukudlala futhi bayazijabulisa kakhulu. Kodwa amahlengethwa awasondeli kubantu.
- Kusuka esiGrekini sasendulo, igama elithi dolphin lihunyushwa ngokuthi mfowethu. Mhlawumbe yingakho eGrisi lasendulo kwanikezwa isigwebo sentambo ngokubulala lesi silwane.
- Njengendoda, ihlengethwa elisemaceleni amhlophe lingahlukanisa phakathi kokunambitheka, kepha umuzwa wabo wokuhogela awukho nhlobo.
