Omunye woshaka owaziwa ukuthi ungomunye wezinhlobo ezindala kakhulu ezikhona emhlabeni yi ushaka we-eel. Ngokuhamba kwesikhathi kuye kwabizwa ngokuthi ifosili ephilayo. Lokhu kungenxa yokuthi lesi silwane besiphile kusukela ezikhathini zangaphambi komlando futhi sisaphila nanamuhla. Kodwa-ke, yize lokhu kungaba okujwayelekile kakhulu kwezinye izinhlobo, lokhu akukaze kube nokuvela kwesinye isikhathi sonke lesi sikhathi.
Ngakho-ke, sizonikezela le ndatshana ku-eel shark. Uma ufuna ukwazi i-biology yayo, indlela yokuphila, ukudla nokukhiqiza kabusha, lokhu okuthunyelwe kwakho 🙂
Izici eziyinhloko
Imvamisa, zonke izinhlobo zezinto ziyahlangabezana nokujwayeleka kwemvelo ngokuhamba kwesikhathi futhi ziguquke. Izimo zezemvelo kanye nokuxhumana nabanye abantu ezindaweni zemvelo nasezimisweni zezemvelo akuhlali kufana ngaso sonke isikhathi. Ngakho-ke, izinhlobo zivame ukuthuthuka kuzakhi zazo zofuzo amanye amasu azisizayo ukuze ziphile kangcono kulezi zindawo futhi uphumelele kakhulu kukho konke ukusinda nokuzala.
Kodwa-ke, i-eel shark ayikaze ibhekane nezinguquko kusukela ezikhathini zangaphambi komlando. Kuseseyisilwane esinezici ezicishe zifane nezasukela lapho saqala khona. Lokhu kubangela ukuthi ibizwe ngezinsalela eziphilayo njengoba kuyizinhlobo zezilwane ezinezici zangaphambi komlando.. Yize kuyisilwane esaziwa kakhulu ngabantu cishe emhlabeni wonke, akukho lwazi oluningi olwaziwayo ngaso.
Kuyaziwa ngezindlela eziningi ngokuba uhlobo oludumile kangaka. Igama lika-eel shark livela ekubunjweni kwalo elifana nenyoka yamanzi. Kungumndeni wakwaChlamydoselachidae futhi unamanye amagama ajwayelekile anjenge-ruff shark. Kulezi zinsuku, Sibona ngaphakathi kohlu lwezilwane ezicishe zisongelwe yi-International Union for Conservation of Nature (IUCN). Isizathu sokuthi bacishe basongelwe ukuthi bazingelwa ngephutha ekujuleni nge-trawling nezinye izindlela zokuvuna.
Lapho befika kusuka ekujuleni kuya phezulu bafika sebeshonile, ngoba abakwazi ukumelana nezinguquko ezingazelelwe kwengcindezi. Esinye isici abacishe basongelwe ukuthi ukuzala okuhamba kancane abanakho. Uma singeza ukuthi badinga iminyaka eminingi ukuzala futhi bandise inani labo ababanjwe ngalo ngengozi, kuyinto ejwayelekile ukuthi inani labantu bohlobo oluthile lincane futhi lincane.
Descripción
Umzimba ka-eel shark mncane kakhulu uma uqhathaniswa nabanye oshaka. Ungumzimba ofana nowe-eel. Imvamisa, zinobude obumaphakathi cishe bamamitha ama-2. Lokhu akusho ukuthi bonke abantu balobukhulu obungaka. Abanye bahlolwe ngobude obufinyelela kumamitha ama-4.
Impumulo isengxenyeni emaphakathi yengaphambili lekhanda elinomumo oyindilinga. Yize kungacaci ngokuphelele, iphatha cishe amazinyo angama-300 esewonke. Izisabalalisiwe emigqeni engu-25 eguqukayo, okusho ukuthi cishe noma iyiphi inyamazane ayikwazi ukuphunyula kulo shaka obulalayo.
Amandla anawo emhlathini wayo nokuma kwayo kuyisiza ukuthi igwinye inyamazane enkulu ngaphandle kwezinkinga. Umbala kashaka unombala onsundu onsundu. Inamaphiko emumva, okhalweni nasesinqeni ngaphezu kokuvuleka kwama-gill ayisithupha.
Babhukuda ngokushesha okukhulu. Okunye okuthandwayo okuheha ukunakwa kwalaba oshaka ukuthi, uma bebhukuda ngejubane eliphezulu, bakwenza lokho bevule imilomo. Bayizilwane ezingenakuphila ngaphandle kwendawo yazo noma ekuthunjweni, noma ngabe zinikezwa ukunakekelwa okungakanani.
Indawo nendawo okusatshalaliswa kuyo
Lezi zilwane zihlala ekujuleni okukhulu impela. Phakathi kwalokhu nokuthi abanakugcinwa ekuthunjweni, kuyinto ejwayelekile ukuthi akukho okuningi okwaziwayo ngalezi zinhlobo. Awukwazi nje ukwenza izifundo ngazo. Imvamisa zihlala endaweni ejulile engama-600 metres, ubuncane bamamitha ayi-150. Yisona esiseduze kunazo zonke ezake zabonwa ngaphezulu.
Okuwukuphela kwendlela yokuziletha ebusweni ukuthi zifune ngokulangazela ukudla. Kodwa-ke, bakwenza ebusuku, ngoba abafuni ukubonwa nganoma iyiphi indlela.
Indawo yayo yokusatshalaliswa ibanzi impela kepha inokuhlamvu okungajwayelekile. Singabathola e-Angola, eChile, eNew Zealand, eJapane, eSpain, nasezilwandle i-Atlantic nasePacific.
Ukondla nokukhiqiza kabusha i-eel shark
Ukudla lo shaka anakho kuhluka kakhulu. Ngoba umzimba wayo uyayivumela ukuthi igwinye isisulu sonke, ingadla izilwane ezahlukahlukene. Ekudleni kwayo ikakhulu kufaka phakathi ama-squid, ama-cephalopods, ezinye izinhlanzi ngisho noshaka.
Ubhekwa njengomzingeli onekhono futhi osatshwayo. Kuvame ukuzingela ebusuku ukugwema ukubonwa nokubamba ezinye izinhlobo ngokungazelele. Ingafihlwa kahle ngenxa yombala wesikhumba sayo futhi iyisebenzisa njengesimanga sokuhlasela isisulu. Mhlawumbe le mpumelelo ekudleni kwayo nakulezi zici yenza kungadingeki ukuthi iguquke ukuze ivumelane nezindawo ezahlukahlukene. Ngenxa yombala wayo ifihliwe, ibhukuda ngejubane eliphezulu futhi inemigqa yamazinyo nomhlathi oyivumela ukuthi igwinye isisulu sonke. Ngazo zonke lezi zici, akudingeki ukuthi ziguquke, ngakho-ke kuseseyinhlobo yakudala, kepha namuhla.
Mayelana nokuzala kwayo, kungohlobo lwe-ovoviviparous. Ekuzalweni ngakunye kunezingane eziphakathi kuka-5 no-12. Abancane badinga isikhathi eside sokukhulelwa. Kumele bakhule phakathi kweminyaka emi-2 nengu-3. Lokhu yilokhu esikhulume ngakho ngaphambili ngesinye sezizathu esenza ukuthi loluhlobo lusengozini. Phakathi kokubanjwa ngengozi, isidingo sezikhathi zokukhulelwa ezineminyaka emi-2 kuya kwemi-3 futhi, kuyo yonke inzalo, hhayi bonke baba ngabantu abadala, kuyinto ejwayelekile ukuthi abantu babe yingozi.
Lapho nje abasha sebeshiyile isidumbu sikanina, ngokuvamile aphakathi kuka-40 no-60 cm ubude. Bayizisulu zezinye izilwane ezidla ezinye lapho bengakakwazi ukuzivikela.
Ngiyethemba lolu lwazi lukusiza ukwazi okwengeziwe nge-eel shark.
