I-wobbegong enamabala (i-Orectolobus maculatus) ingeyoshaka, igama layo lesibili yi-Australian carpet shark.
Ukusabalala kwe-wobbegong enamabala.
I-wobbegong enamabala itholakala emanzini asogwini lwaseningizimu naseningizimu-mpumalanga ye-Australia, esifundeni saseFremantle seWestern Australia, eduze nesiQhingi saseMoreton eSouth Queensland. Mhlawumbe lolu hlobo lusatshalaliswa emanzini aseJapan kanye naseningizimu yeChina Sea.
Indawo ehlala iWobbegong.
I-wobbegongs enamabala akuyona oshaka be-benthic futhi itholakala ezindaweni zasolwandle ezisukela ezindaweni ezifudumele kuya ezindaweni ezishisayo. Indawo yabo enkulu yizindawo ezingasogwini eziseduze namashalofu ezwekazi, ukusuka endaweni enamanzi amaningi kuya ekujuleni kwamamitha ayi-110. Bahlala ezixhotsheni zamakhorali nasemadwaleni, emfuleni, ezindaweni lapho kugcwele ulwandle, ezindaweni ezingasogwini nasezindaweni ezinesihlabathi. I-wobbegongs enamabala ikakhulukazi yasebusuku, etholakala emihumeni, ngaphansi kongqimba lwamatshe anamatshe namakhorali, naphakathi kokuphahlazeka komkhumbi. Oshaka abasebasha bavame ukutholakala emachwebeni ane-algae, lapho amanzi ejwayele ukujula ngokwanele ukumboza ngokuphelele umzimba wezinhlanzi.
Izimpawu zangaphandle ze-wobbegong ezinamabala.
I-Wobbegongs enamabala ingamasentimitha ayi-150 kuya kwayi-180 ubude. Ushaka omkhulu, obanjiwe ufike kubude obungamasentimitha angama-360. Izingane ezisanda kuzalwa zinobude obungu-21 cm. Umbala we-wobbegongs onamabala uyahambisana nombala wendawo abahlala kuyo.
Imvamisa iba nombala ophuzi ophuzi noma onsundu ngokuluhlaza okotshani ngezindawo ezinkulu, ezimnyama ngaphansi komugqa womzimba. Izindawo ezimhlophe ezimiswe okwe "o" zivame ukumboza wonke umhlane kashaka. Ngaphandle kwephethini yombala ohlukile, ama-wobbegongs anemibala atholakala kalula ngekhanda lawo eliyisicaba elinama-lobes esikhumba ayisithupha kuya kwayishumi ngezansi naphambi kwamehlo.
Izimpondo ezinde zamakhala zitholakala zizungeze ukuvuleka komlomo nasemaceleni ekhanda. I-Antennae kwesinye isikhathi inamagatsha.
Ulayini womlomo uphambi kwamehlo futhi unemigqa emibili yamazinyo emihlathini engenhla kanye nemigqa emithathu emihlathini engezansi. I-wobbegongs enamabala inemibono emikhulu futhi ayinazo izigaxa zesikhumba noma ama-protrusions emhlane. Amaphiko omgogodla athambile kanti owokuqala utholakala ezingeni lesisekelo se-pelvic se-anal fin. Amaphiko wepectoral kanye ne-pelvic makhulu futhi abanzi. Isiphetho se-caudal sifushane khulu kunamanye amaphiko.
Ukukhiqizwa kabusha kwe-wobbegong enamabala.
Kuncane okwaziwayo ngenkathi yokuzalanisa yemvelo yama-wobbegongs abonakalayo, kepha, ekuthunjweni, ukuzalanisa kuqala ngoJulayi. Ngesikhathi sokuzala, abesifazane baheha abesilisa abanama-pheromones akhishwe emanzini. Ngesikhathi sokukhwelana, owesilisa uluma insikazi esifundeni se-branchial.
Ekuthunjweni, abesilisa bahlala bencintisana nabesifazane, kepha akwaziwa ukuthi ubudlelwano obunjalo buqhubeka yini emvelweni.
Ama-wobbegongs abonisiwe angaphansi kwezinhlanzi ezi-ovoviviparous, amaqanda akhula ngaphakathi komzimba kamama ngaphandle kokudla okwengeziwe, anokutholakala kuphela kwe-yolk. Amafry akhula ngaphakathi kowesifazane futhi imvamisa adla amaqanda angenamvumba. Imvamisa kuvame ukuvela amawundlu amakhulu ku-brood, inani labo lilinganiselwe ngama-20, kepha amacala angama-37 gazinga ayaziwa. Oshaka abancane bashiya umama wabo ngokushesha ngemuva kokuzalwa, kaningi ukuze bangadliwa nguye.
Ukuziphatha okubonakalayo kweWobbegong.
I-wobbegongs enamabala iyizinhlanzi ezingasebenzi uma kuqhathaniswa nezinye izinhlobo zoshaka. Imvamisa zilenga zinganyakazi ngokuphelele ngaphezu kolwandle, ngaphandle kokubonisa umuzwa wokuzingela, isikhathi eside. Ukuphumula kwezinhlanzi usuku lonke. Umbala wabo wokuzivikela ubavumela ukuba bahlale bengabonakali. Ama-wobbegongs amachashaza abuyela njalo endaweni efanayo, ayizinhlanzi ezizimele, kepha kwesinye isikhathi akha amaqembu amancane.
Zondla ikakhulukazi ebusuku futhi zibhukuda eduzane, nokuziphatha kwazo ziyefana nawo wonke amanye oshaka. Amanye ama-wobbegongs abonakala enyonyobela isisulu sawo, awanandawo ethile yokudla.
Ukudla i-wobbegong enamabala.
I-wobbegongs enamabala, njengoshaka abaningi, yizilwane ezidla ezinye futhi zondla ikakhulukazi ama-invertebrate angenawo amagciwane. Ama-lobster, izinkalankala, octopus nezinhlanzi ezingamathambo ziba yizisulu zazo. Bangabamba futhi abanye oshaka abancane, kufaka phakathi izingane zezinhlobo zazo.
Ama-wobbegongs aboniwe ngokuvamile alindela inyamazane engaqaphile engalunywa kalula amaphiko abo.
Zinomlomo obanzi omfushane nomphimbo omkhulu obanzi obonakala sengathi umunca inyamazane yazo kanye namanzi.
I-wobbegongs enamabala iveza umhlathi phambili, ngenkathi ngasikhathi sinye ikhulisa imbobo yomlomo futhi idala amandla amaningi okuncela. Le protrusion eyengeziwe namandla akhuphukile wokudonsa ahlanganiswe nemihlathi enamandla kanye nemigqa eminingi yamazinyo akhulisiwe emhlathini ongenhla nophansi. Imishini enjalo idala isicupho sokubulala isisulu.
Okusho umuntu.
I-wobbegongs enamabala yakha ingxenye encane yokubanjwa kwezokudotshwa kwezinhlanzi futhi imvamisa ibanjwa ngamathegi.
Zithathwa njengezinambuzane embonini yokudoba ama-lobster asolwandle ngakho-ke zikhangwa izingibe ezizosetshenziswa njengezithiyo.
Izidlo ezenziwe ngenyama kashaka zithandwa kakhulu, ngakho-ke ukuzinza kwenani lalezi zinhlobo kusongelwa. Isikhumba esiqinile futhi esihlala isikhathi eside naso siyabaluleka, lapho kwenziwa khona izikhumbuzo ezinephethini eliyingqayizivele lokuhlobisa. I-wobbegongs enamabala ngoshaka abazolile abaheha abathandi bokuntywila ngakho-ke banegalelo ekuthuthukisweni kwezokuvakasha kwezemvelo. Kepha zingaba yingozi futhi zibe nolaka lapho zihlaselwa futhi zikwazi ukudala umonakalo omkhulu kubahlaseli.
Isimo sokonga se-wobbegong esibonakalayo.
Ngokwe-IUCN Species Survival Commission, i-wobbegong ebonwayo isengozini enkulu. Kepha ayinakho ukuhlolwa kwezinqubo zokufakwa ohlwini njengezilwane ezisengozini. IConference on International Trade in Endangered Species of Wild Fauna and Flora (CITES) nayo ayinikezi simo esikhethekile kule wobbegong enamabala. Ama-wobbebongs amachashazi avame ukubanjwa kumanetha njenge-by-catch futhi abe nokubamba okuphansi futhi okuzinzile ezindaweni zokudoba eziseningizimu nasentshonalanga ye-Australia. Kodwa-ke, kukhona ukwehla okuphawulekayo enanini loshaka balolu hlobo eNew South Wales, okukhombisa ukuba sengozini kokudonswa kwezinhlanzi ekudobeni. Ukudoba ngokuzilibazisa akubonakali kuyingozi ethile koshaka, ngoba kubanjwa inani elincane kuphela lezinhlanzi.
Ama-wobbegongs aboniwe ngokuvamile abhubha ezindaweni zawo ezingasogwini endaweni esogwini. Okwamanje azikho izinyathelo ezithile zokongiwa kwalezi zinhlobo zikashaka e-Australia. Amanye ama-wobbegongs abonakele atholakala ezindaweni eziningana ezivikelwe zasolwandle eNew South Wales, kufaka phakathi iJulian Rocky Water Sanctuary, iSecluded Islands Marine Park, iHalifax, neJervis Bay Marine Park.
