Phila isipiliyoni sokuntywila nolunye lwezinhlobo ezihlaba umxhwele emhlabeni: ushaka omhlophe, ofika izinyanga ezimbalwa ngonyaka esiQhingini saseGuadalupe, eMexico.
Sihlela umkhankaso oya eGuadalupe Island ngenhloso yokuhlangana eduze nalo shaka omuhle. Esikebheni basamukela ngemargaritas ethile futhi basikhombisa igumbi lethu. Usuku lokuqala lusetshenziselwe ukuhamba ngomkhumbi, ngenkathi izisebenzi zichaza ukusebenza kwe-cage diving.
Lapho sifika kulesi siqhingi, ebusuku safaka amakheji amahlanu: amane ngamamitha ama-2 ukujula kanti awesihlanu ngamamitha ayi-15. Banamandla okwamukela abatshuzi abangu-14 ngasikhathi.
Isikhathi esihle sesifikile!
Ngakusasa, ngo-6: 30 ekuseni, amakheji avulwa. Besingasakwazi ukubekezelela isifiso sokuxhumana ne- oshaka. Ngemuva kokulinda kancane, cishe imizuzu engama-30, kwavela isithunzi sokuqala sicathamela isicupho. Indlela esasizizwa ngayo yayingachazeki. Ngokuphazima kweso, kwase kukhona oshaka abathathu ababejikeleza, ngubani owayezoba ngowokuqala ukudla umsila we-tuna othakazelisayo owalenga entanjeni encane? Onamandla amakhulu wavela ekujuleni lapho amehlo akhe ethe njo enyameni futhi lapho efika kuyo, wavula umhlathi wakhe omkhulu futhi kungakapheli nemizuzwana emibili wadla isicupho. Sakubona lokhu samangala, asikholwanga ukuthi akakhombisanga intshisekelo nakancane kithi.
Kanjalo nezinsuku ezimbili ezalandela lapho sithole khona ithuba lokubona okungaphezulu kwe- Izinhlobo ezi-15 ezahlukahlukene. Siphinde sabona amakhulu ezinkulungwane amahlengethwa asebhodleleni ababhukuda phambi komnsalo wesikebhe esifuthayo, ngenkathi sithatha olunye uhambo ukubona i- izindlovu zezimpawu Y izimpawu zoboya kusuka eGuadalupe
Ukwelashwa kwe-VIP ebhodini
Njengokungathi lokho bekunganele, ukuhlala kwethu emkhunjini bekuyisigaba sokuqala, besineJacuzzi yokufudumeza emanzini abandayo aphakathi kokuntywila; iziphuzo, ukudla okulula kanye nokudla okuhle kakhulu njenge-Alaska crab, i-salmon, i-pasta, izithelo, ama-dessert namawayini angcono kakhulu avela esifundeni saseGuadalupe Valley.

Impumulo yayo iyindilinga, imfishane futhi iminyene, lapho kunezindawo ezimnyama ezibizwa nge- "lorenzini blisters", ezikwazi ukubona insimu kagesi encane ukusuka kumamitha ambalwa ukusuka lapho. Umlomo wayo mkhulu kakhulu futhi kubonakala sengathi umamatheka unomphela njengoba ukhombisa amazinyo alo amakhulu, angunxantathu. Amakhala acinene kakhulu, kanti amehlo mancane, ayindilinga futhi amnyama bhuqe. Ezinhlangothini, kunama-gill amahlanu ohlangothini ngalunye kanye namaphiko amabili amakhulu we-pectoral. Ngemuva kwayo inamaphiko amabili amancane okhalo kanye nesitho sayo sokuzala, kulandele amaphiko amabili amancane; ngomsila, isiphetho somsila esinamandla futhi, ekugcineni, isiphetho somhlane esingaqondakali sonke esisaziyo nesiveza lokho
Yize igama lalo, lo shaka umhlophe esiswini kuphela, kanti ngemuva umzimba wakhe unombala o-grey-grey. Le mibala isetshenziselwa ukuxubana nokukhanya kwelanga (uma kwenzeka ubheka kusuka ngezansi), noma namanzi olwandle amnyama (uma kungenzeka ukwenze phezulu), okwenza ukufihla kube lula njengoba kusebenza.
Zivela nini futhi kungani?
Bavakashela lesi siqhingi kuphela phakathi kwezinyanga zika ngoJulayi nangoJanuwari. Kodwa-ke, abanye bayabuya unyaka nonyaka futhi lapho bethutha baya endaweni ethile maphakathi nePacific, nasezindaweni ezikude njengeziQhingi zaseHawaii. Yize kubhalwe kahle, izindlela zokuhamba endaweni eseduze nesiqhingi aziwa.
Muva nje, izifundo ze-acoustic telemetry seziphenduke ithuluzi elibalulekile lokuchaza ukunyakaza nokusetshenziswa kwendawo koshaka ezingxenyeni ezahlukene zomhlaba, yingakho i-Interdisciplinary Center for Marine Sciences, enothisha wesayensi iMauritius IHoyos ekhanda, isungule iphrojekthi egxile ekutadisheni ukusebenza kwalezi zinhlobo ngosizo lwaleli thuluzi.
