Izici nendawo yokuhlala
IMacropinna iyinhlanzi engaqondakali yolwandle. IMacropinna microstomy - inhlanzi incane ngosayizi futhi, ngisho nasezimweni ezingandile, ubukhulu bayo abudluli amasentimitha ayi-15. Izikali ezimnyama zimboza ingxenye enkulu yomzimba wesidalwa esinjalo esichitha impilo ekujuleni kolwandle.
Isithombe sikaMacroninna siyakhombisa, Ukuhlola ukubukeka kwayo, amaphiko ayindilinga, abanzi futhi amakhulu abonakala ngokusobala. Amehlo ezinhlanzi ayizigaxa, umphimbo uyahlaba umxhwele, umlomo mncane. Lo mhlali wamanzi, obizwa ngenye indlela: i-smallmouth macropinna, watholakala futhi wachazwa ngekhulu elidlule.
Kepha kuphela ekuqaleni kwalonyaka lapho bekwazi khona ukuthola izithombe zezidalwa eziyimfihlakalo eziveza imfihlo yemininingwane eyingqayizivele yesakhiwo sazo. Okuvelele ukuthi ikhanda lenhlanzi enjalo lisobala, okungajwayelekile kunoma yisiphi isidalwa kulo mhlaba.
Kuyathakazelisa ukwazi ukuthi iqiniso elinjalo kwakungelula kangako ukuthola ngaphambili, ngoba kwakungekho mishini ekhombisa ngokusobala imininingwane yokubonakala kwezidalwa ezihlala ekujuleni okukhulu. Futhi i-dome e-translucent ethe-ethe, lapho imvelo yanikeza lesi sidalwa esiphilayo, yawa ngokushesha ngesikhathi inhlanzi isuswa emanzini.
Ukubuka okuphezulu kwemakropinnu yezinhlanzi
Ngebunzi elibonakalayo lesidalwa esingahle simangale, umuntu angabona ngandlela thile isakhiwo sangaphakathi. Isici esithakazelisa kakhulu sesakhiwo saso, okokuqala, ngamehlo ahlaba umxhwele ahlukile, atholakala echibini eligcwele uketshezi olukhethekile, kepha hhayi ngaphandle, njengezidalwa ezijwayelekile zomhlaba, kodwa ngaphakathi komzimba.
Futhi ebusweni besikhumba senhlanzi esobala kukhona kuphela izitho zephunga, ezithola izinguquko ezahlukahlukene emhlabeni ozungezile. I-Macropinn ungummeleli wesigaba sezinhlanzi ezenziwe ngemisebe, ezisatshalaliswa ezindaweni ezinamazinga okushisa aphansi nasendaweni eshisayo, ezitholakala enyakatho Nenkabazwe ekujuleni kolwandle iPacific Ocean, futhi eduze nayo, amanzi eBering Strait kanye noLwandle lwase-Okhotsk.
Izidalwa ezinjalo zitholakala nasemanzini aseKamchatka naseJapan, ekujuleni kwamanzi afinyelela ogwini lwaseCanada. Emndenini opisthoproct, lapho lezi zinto eziphilayo zingezakho, namuhla, ngokusho kososayensi, kunezinhlobo ezingaba yishumi nambili.
Uhlamvu nendlela yokuphila
Lesi silwane sinegama elehlukile - umgqomo iso yedivayisi efanelekile yezitho eziyizigaxa zombono, eziwusizo kakhulu emvelweni lapho impilo yezinhlanzi ezihlala ekujuleni kolwandle ngaphansi kwekholamu lamanzi ukusuka kumamitha amahlanu kuya kwamakhulu ayisishiyagalombili.
Imisebe yelanga ingena kancane kulezi zindawo eziyizithulu, okushiye uphawu embonweni wezidalwa ezingaphansi kwamanzi, ezikwazi ukubona ngisho nasebumnyameni obukhulu. Ukukhanya okuwela emehlweni ezinhlanzi kuzikhanyisa ngombala ogqamile oluhlaza. Isizathu salesi simo yinto ekhethekile ehlunga imisebe yokukhanya.
Lokhu kubhekwa ezicini zezidalwa ezinjengezinye iqiniso elithakazelisayokodwa i-smallmouth macropyne - isidalwa esingaqondakali ukuthi ngokucwaninga ngokujulile kwezimfihlo kuba ngaphezulu kuphela. Izakhamuzi ezinhle zokujula ezikude aziyeki ukumangaza ososayensi, kepha lokhu kuyaqondakala, ngoba izidalwa ezikude nempucuko nempahla yomhlaba ohluke ngokuphelele.
Kunzima ngomuntu ukuthi ahlale endaweni okunzima ukuyifinyelela futhi eyingozi yendawo yakhe yokuhlala, futhi angeke abekhona emhlabeni wethu. Ekujuleni okukhulu, lapho bajwayele ukuhlala khona, ngisho nengcindezi yehluke ngokuphelele. Kungakho-ke, uma ukhipha inhlanzi enjalo emanzini, ingxenye ebushelelezi engaphambili yekhanda labo iqhuma edonsi layo.
Ukwakheka kwamaphiko ezinhlanzi nakho kuyindlela enhle yokubhukuda ngokunethezeka nemigwaqo emangalisa emanzini olwandle ajulile. Kodwa-ke, akunakushiwo ukuthi izidalwa ezinjalo zibonisa umsebenzi obaluleke kakhulu. Ziyahamba kancane, futhi lapho zibhukuda, zivame ukuma zibambe endaweni eyodwa.
Ingabe lezi zilwane ezicishe zibe mnandi zinezitha? Akukwazi okwanele ngalesi sayensi okwamanje, ngoba kunzima kakhulu ukugcina imininingwane yokuhamba nendlela yokuphila yalezi zinhlanzi ekujuleni kolwandle.
USmallmouth Macropyne
Izindlela zabo azihambelani nezindlela zomuntu. Futhi asikho isidingo sokuthi bahlangane. Abahlali bamathumbu abanandaba nabantu, futhi abantu, ngaphandle kwelukuluku nokulangazelela ulwazi, abanayo inzuzo ebonakalayo yesisu kubo. Izici zesimo somzimba wazo zenza kube nzima ngabantu ukuthi badle izidalwa ezinjalo.
Ukudla okunomsoco
Ukuhamba kancane i-smallmouth macropinny – inhlanzi enekhanda elisobalaakumvimbi ukuba abe ngumzingeli ophumelelayo. Njengoba zinamehlo akhethekile amise okwomgqomo atholakala ngaphakathi kwekhanda futhi evikelwe ngegobolondo elisobala, lezo zidalwa ziyakwazi ukubona umhlaba obazungezile, ngokuvundlile nangokuqondile, okubavumela ukuthi babheke ngempumelelo isisulu okuhlosiwe futhi bangaphuthelwa yimininingwane yokuhamba kwayo.
Uma isisulu singenakho ukubhukuda sisondele eduze kwesitha esinamehlo amakhulu, khona-ke siyabanjwa ngokushesha, sithola ukuphela kwaso okudabukisayo. Emini, izinhlanzi ezinjalo zenza ukunyakaza okujwayelekile, zikhuphuke, noma kungekude amabanga amade, ziye ezingxenyeni ezingenhla zamanzi, lapho zithola khona ukudla kwazo, kuthi ebusuku ziyehle emuva.
Akunzima ukuqonda ukuthi abazingeli basemanzini bayizilwane ezizingelayo. Kepha abanasifiso sokudla okukhulu. Ngenxa yobukhona bomlomo omncane (izinhlanzi ezathola igama lazo i-smallmouth), zinamandla okudla kakhulu ama-plankton, ama-siphonophore tentacles, ama-crustaceans nezinye izilwane ezincane.
Ukuzala kanye nesikhathi sokuphila
I-Macropinn – inhlanzi kungaqondakali kahle, njengoba sekushiwo. Ososayensi baqala ukuqonda imininingwane eyingqayizivele yendlela yokuphila yalezi zidalwa eziphila ekujuleni kolwandle. Okufanayo kusebenza nasezindleleni zokukhiqiza kabusha izinhlanzi, okungaqondakali kangako ngazo.
Kepha kuyaziwa ngokuqinisekile ukuthi abesifazane bezinhlanzi ezimangalisayo bazala ngobuningi. Futhi gazinga elivela kulo, ekuqaleni babenomzimba ovulekile, ongafani ncamashi nabazali babo. Kodwa-ke ama-metamorphoses amaningi aqala ukuvela nawo, aze athathe ukubukeka kwemvelo kwabantu abadala.
Ubunzima bokubuka izilwane ezijulile zolwandle ngesinyathelo ngesinyathelo empilweni yazo yonke sekuba ngumphumela weqiniso lokuthi ubude bayo bungenye imfihlakalo kososayensi. Futhi ukugcina e-aquarium, ngokubheka izici zokwakheka kwezinto ezinjalo ezingaqondakali, ezingatadiswanga kangako, ezilungiselelwe ngokukhethekile, kunzima kakhulu futhi kuyinkinga.
Kodwa-ke, laba bameleli abayimfihlakalo bezilwane bakwazi ukwabekwa futhi bagcinwa ngempumelelo e-aquarium eCalifornia. Lesi sakhiwo, esiphenduke ikhaya elisha lezinhlanzi ezingaqondakali, sithathwa njengesinye sezinkulu kunazo zonke emhlabeni, futhi sinezinhlobo eziningi ezimangalisayo zezilwane zasemanzini, ezigcinwe kumadamu angama-93.
Futhi nsuku zonke izigidi zababukeli abanelukuluku banethuba lokubuka izidalwa ezimangalisayo, ezinhle futhi ezihlukile. Ngakho-ke, kungathenjwa ukuthi kungekudala kuzokwambulwa zonke izimfihlo ze-macropine.
