Inkalankala eluhlaza okwesibhakabhaka (ngesiLatin - Callinectes sapidus) ingeyesigaba se-crustacean.
Incazelo yokubukeka kwenkalankala eluhlaza okwesibhakabhaka.
I-crab eluhlaza okwesibhakabhaka ibonakala kalula ngombala we-cephalothorax, umbala uvame ukuluhlaza okwesibhakabhaka. Umzimba osele unombala onsundu womnqumo. Izitho zombili ezinhlanu zimise okwe-paddle, futhi zenzelwe ukunyakaza emanzini. Owesifazane une-carapace ebanzi engunxantathu noma eyindilinga namachashazi abomvu kuma-pincers, kuyilapho i-cephalothorax yowesilisa imiswe njenge-T. Inkalankala eluhlaza okwesibhakabhaka ingaba nobude be-carapace obufinyelela kuma-25 cm, ne-carapace ecishe iphindwe kabili ububanzi. Ukukhula okusheshayo ikakhulukazi kwenzeka ehlobo lokuqala, kusuka ku-70-100 mm. Ngonyaka wesibili wokuphila, inkalankala eluhlaza okwesibhakabhaka inamagobolondo angama-120-170 mm ubude. Usayizi we-crab yabantu abadala ufinyelelwa ngemuva kwe-18 - 20 molts.
Ukusabalalisa inkalankala eluhlaza okwesibhakabhaka.
Inkalankala eluhlaza okwesibhakabhaka isakazeka isuka entshonalanga ye-Atlantic Ocean, isuka eNova Scotia iye e-Argentina. Ngengozi noma ngamabomu, lolu hlobo lwethulwa e-Asia naseYurophu. Ihlala futhi eHawaii naseJapan. Kutholakala e-Uruguay nasenyakatho, kufaka phakathi iMassachusetts Bay.
Indawo ehlala inkalankala eluhlaza okwesibhakabhaka.
Inkalankala eluhlaza okwesibhakabhaka ihlala ezindaweni ezahlukahlukene ezisukela emanzini anosawoti amatheku olwandle kuya emanzini aseduze-amasha ezindaweni ezivalekile. Ikakhulukazi ihlala emilonyeni yemifula ngamanzi amasha, futhi ihlala eshalofini. Indawo yokuhlala yenkalankala eluhlaza okwesibhakabhaka isukela kulayini wamaza asezingeni eliphansi kuya ekujuleni kwamamitha angama-36. Abesifazane bahlala emanzini anosawoti omningi ezindaweni ezizalela emfuleni, ikakhulukazi ngesikhathi sokubeka amaqanda. Ngezikhathi ezibandayo, lapho izinga lokushisa kwamanzi liba likhaza, izinkalankala eziluhlaza zifudukela emanzini ajulile.
Ukuzalela inkalankala eluhlaza okwesibhakabhaka.
Isikhathi sokuzalaniswa kwezinkalankala eziluhlaza okwesibhakabhaka sincike esifundeni lapho zihlala khona. Isikhathi sokuzala siqala ngoDisemba kuya ku-Okthoba. Ngokungafani nabesilisa, abesifazane bahlangana kanye kuphela empilweni, ngemuva kokuthomba noma i-molt yokuphela. Abesifazane baheha abesilisa ngokukhipha ama-pheromones. Abesilisa bancintisana nabesifazane futhi babavikele kwamanye amaduna.
Izinkalankala eziluhlaza okwesibhakabhaka ziningi kakhulu, kanti abesifazane bazalela amaqanda ayizigidi ezimbili kuya kweziyisishiyagalombili lapho kuzalwa. Lapho abesifazane besembozwe ngegobolondo elithambile ngokushesha ngemuva kokuncibilika, abesilisa nabesilisa bagcinwa kwabesifazane izinyanga ezi-2 kuya kwezi-9. Bese kuthi abesilisa bagade insikazi kuze kube yilapho ikhava entsha ye-chitinous iqina. Lapho abesifazane belungele ukuzala, amaqanda avundiswa yisidoda esigciniwe bese ebekwa ezinweleni ezincane zezinsiza ezisesiswini.
Lokhu kwakhiwa kubizwa nge- "sponge" noma "berry". Isikhathi sokufukamela samaqanda enkalankala eluhlaza okwesibhakabhaka izinsuku eziyi-14-17. Ngalesi sikhathi, abesifazane bathuthela ezizalweni zemilambo ukuze izibungu zingene emanzini anosawoti omningi. Imibungu yenkalankala eluhlaza okwesibhakabhaka ikhula ngosawoti okungenani we-20 PPT, ngaphansi kwalomngcele, inzalo ayiphili. Izibungu zivela kaningi esiqongweni samanzi. Izibungu zezinkalankala eziluhlaza okwesibhakabhaka zidluliswa ngamanzi eduze nogu, futhi ukukhula kwazo kuqedwa emanzini eshalofu asogwini. Umjikelezo wonke wezinguquko uvela ezinsukwini ezingamashumi amathathu kuye kwezingamashumi amahlanu. Izibungu bese ziyabuya zihlale emachwebeni, lapho zigcina zikhule zibe inkalankala yabantu abadala. Izibungu zidlula ezigabeni eziyisishiyagalombili zenguquko esikhathini esiyizinyanga cishe ezimbili ngaphambi kokuba ziqale ukufana nenkalankala yabantu abadala. Abesilisa, njengomthetho, abayivikeli inzalo yabo, abesifazane bavikela amaqanda kuze kuvele izibungu, kepha abayinakekeli inzalo ngokuzayo. Izibungu zingena ngokushesha emvelweni, ngakho-ke iningi lazo lizofa ngaphambi kokufinyelela esigabeni sabantu abadala.
Imvamisa inkalankala eyodwa noma ezimbili kuphela ezisindayo, ezingazala, futhi zihlala endaweni yazo kuze kube yiminyaka emithathu. Eziningi zazo ziba yizisulu zezilwane ezidla inyama nabantu ngaphambi kokuba zikhule.
Ukuziphatha kwenkalankala eluhlaza okwesibhakabhaka.
Inkalankala eluhlaza okwesibhakabhaka inolaka ngaphandle kwezikhathi zokuncibilika lapho i-carapace isathambile. Ngalesi sikhathi, usengozini enkulu. Inkalankala izigqiba esihlabathini ukuze icashe ezilwaneni eziyingozi. Emanzini, uzizwa ephephile futhi ebhukuda ngenkuthalo. Imilenze yayo yakamuva yokuhamba ilungiselelwe ukubhukuda. Inkalankala eluhlaza okwesibhakabhaka nayo inamabhangqa amathathu emilenze yokuhamba kanye nezinzipho ezinamandla. Lolu hlobo luhamba kakhulu, ibanga eliphelele elimbozwe ngosuku cishe ngamamitha ayi-215.
Inkalankala eluhlaza okwesibhakabhaka isebenza kakhulu emini kunasebusuku. Ihamba cishe ngamamitha ayi-140 ngosuku, ngejubane elijwayelekile lamamitha ayi-15.5 ngehora.
Ku-crab oluhlaza okwesibhakabhaka, kuvuselelwa imilenze ebilahlekile ngesikhathi sokulwa noma ukuzivikela ekuhlaselweni. Endaweni yasemanzini, inkalankala eluhlaza okwesibhakabhaka iqondiswa izitho zokubona nephunga. Izilwane zasolwandle ziphendula amasignali amakhemikhali nama-pheromones, okuzivumela ukuthi zihlole masinyane abalingani abangaba ngabalingani ukusuka kude. Izinkalankala eziluhlaza okwesibhakabhaka nazo zisebenzisa ukubona ngombala futhi zibona abesifazane ngezinzipho zazo ezibomvu.
Ukudla kwenkalankala eluhlaza okwesibhakabhaka.
Izinkalankala eziluhlaza okwesibhakabhaka zidla ukudla okunhlobonhlobo. Zidla izimbaza, zithanda ama-oysters nezimbaza, izinhlanzi, ama-annelids, ulwelwe, futhi cishe noma isiphi isitshalo noma isilwane. Zidla izilwane ezifile, kepha azidli izidumbu ezibolile isikhathi eside. Izinkalankala eziluhlaza kwesinye isikhathi zihlasela izinkalankala ezincane.
Indima ye-ecosystem yenkalankala eluhlaza okwesibhakabhaka.
Izinkalankala eziluhlaza okwesibhakabhaka zizingelwa izingqinamba zase-Atlantic, izindwandwe, nezimfudu zasolwandle. Futhi ziyisixhumanisi esibalulekile ochungechungeni lokudla, ziyizilwane ezidla inyama futhi ziyizisulu.
Izinkalankala eziluhlaza okwesibhakabhaka zigcwele izimuncagazi. Amagobolondo, izikelemu neminyundu kunamathela kusembozo sangaphandle se-chitinous, ama-isopods amancane enza ikolishi ibe ngaphansi komzimba, izimpethu ezincane zikhubaza imisipha.
Yize uC. Sapidus ephethe izimuncagazi eziningi, iningi lazo alithinti impilo yenkalankala.
Incazelo yenkalankala eluhlaza okwesibhakabhaka.
Izinkalankala eziluhlaza okwesibhakabhaka zingaphansi kokudoba. Inyama yala ma-crustaceans imnandi impela futhi ilungiswa ngezindlela eziningi. Izinkalankala zibanjwa ngezicupho ezingunxande, ezinamamitha amabili ububanzi futhi zenziwe ngocingo. Badonswa yisithixo senhlanzi esanda kufiwa. Kwezinye izindawo, izinkalankala nazo zigcina sezisemathunjini nakuma-donks. Abantu abaningi badla inyama yenkalankala, ngoba akuyona ukudla okubizayo nhlobo emazweni asogwini lolwandle.
Isimo sokonga inkalankala eluhlaza okwesibhakabhaka.
I-crab eluhlaza okwesibhakabhaka iyinhlobo ejwayelekile ye-crustacean. Ayizwani nezinsongo ezikhethekile ezinombolweni zayo, ngakho-ke, izinyathelo zemvelo azisetshenziswa kuyo.
