Inyoka yemigqa enemigqa (iRegina alleni) ingeye-squamous oda.
Ukusatshalaliswa kwenyoka enexhaphozi enemigqa.
Inyoka yexhaphozi enemigqa isatshalaliswa kulo lonke elaseFlorida, ngaphandle kwezifunda ezisentshonalanga.
Indawo yokuhlala yenyoka yexhaphozi enemigqa.
Inyoka enamaxhaphozi enemigqa iyinyoka engaqondakali yokugqekeza emanzini etholakala emanzini amile futhi ahamba kancane anezimila eziningi ezintantayo, njengamaxhaphozi e-cypress kanye nezikhukhula zemifula. Kuvame ukutholakala emadanyini lapho kukhula khona i-hyacinth yamanzi. Inani elikhulu lezinyoka zihlala phakathi kwama-hyacinths wamanzi kanye nezindwangu eziminyene zezimila ezintantayo, lapho imizimba yazo iphakanyiswe ngokugcwele noma ngokwengxenye ngaphezulu kwamanzi. Ama-hyacinths amanzi nawo akhangwa yizinambuzane ngenxa yobuningi bezitshalo ezibolile.
Ngaphezu kwalokho, uhlaza oluminyene lwasemanzini luhlinzeka ngokuvikelwa ezilwaneni ezidla izinyoka ezinemigqa. Ubuningi bezinyoka emachibini anjalo kuhlotshaniswa namanzi, anendawo engathathi hlangothi nokuqukethwe okuphansi kwe-calcium encibilikisiwe. Lezi zimo zikhawulela ukukhula kwamapulangwe aminyene ezinwabuzelayo ezidla kuwo. Izinyoka ezinemigqa ezinemigqa zicasha emigodini ye-crayfish ngesikhathi sasebusika nangezikhathi zasentwasahlobo, kanye nasemigodini engaphansi kwamanzi embozwe uhlaza lwasemanzini.
Izimpawu zangaphandle zenyoka yemigqa enemigqa.
Inyoka yemigqa enemigqa inomzimba onsundu omnyama okomnqumo onemigqa emithathu ensundu yobude obugudla ohlangothini lwayo lwangemuva. Umphimbo uphuzi, unemigqa eminingana yamabala phakathi nendawo. Lolu hlobo lwenyoka lwehlukile kwezinye izinhlobo ezilinganisweni ezibushelelezi, ngaphandle kwezikali ezibunjiwe ezeduna, ezitholakala ngemuva ngasemsileni kuya ku-cloaca.
Izinyoka ezinemigqa ezinemigqa zincane kakhulu kuhlobo loRegina. Abantu abangaphezu kuka-28.0 cm ubude babhekwa njengabantu abadala. Izinyoka ezindala zikhula zisuka ku-30.0 ziye ku-55.0 cm, kanti isisindo sazo singama-gramu angama-45.1. Izinhlobo ezinkulu zazinobude bomzimba obungu-50.7 no-60.6 cm.Izinyoka ezincane ezinemigqa emincane zinesisindo esingu-3.1 g ngobude bomzimba obungu-13.3 mm, futhi zehluke kancane ngombala kubantu abadala.
Izinyoka ezinemigqa ezinemigqa zinezimo eziguqukayo zesakhiwo sogebhezi, esiza ukudla kwazo okukhethekile. Ukhakhayi lwawo uhlelo oluyinkimbinkimbi lwamathambo futhi lufakazela ubuchwepheshe be-trophic bale nhlobo. Izinyoka ezinemigqa ezinemigqa zisebenzisa igobolondo eliqinile le-crayfish futhi zinamazinyo ayingqayizivele, ajikayo aguqulelwe ukubamba igobolondo eliqinile le-crayfish. Zondla hhayi kuphela kwi-crayfish encibilikile enamagobolondo athambile. Abesilisa balezi zinhlobo zezinyoka bancane ngosayizi womzimba futhi bavuthwa ngaphambi kwezinsikazi.
Ukukhiqizwa kabusha kwenyoka yemigqa enemigqa.
Izinyoka ezinemigqa ezinemigqa ziyazala ngokocansi, kepha kunolwazi oluncane olutholakalayo mayelana nokuziphatha nokuzala kwezilwane ezihuquzelayo. Ukukhwelana kufanele kwenzeke entwasahlobo. Lolu hlobo lwe-viviparous. Ku-brood, kunezinyoka ezisuka kwezine kuya kweziyishumi nambili (kepha kaningi eziyisithupha). Zibonakala emanzini phakathi kukaJulayi noSepthemba. Ngemuva kweminyaka emi-2, bazala abantwana abanobude bomzimba obungamasentimitha angama-30. Isikhathi sokuphila sezinyoka ezinemigqa emidlalweni asaziwa.
Ukuziphatha kwenyoka yexhaphozi enemigqa.
Izinyoka ezinemigqa ezinemigqa zivame ukukhanya elangeni ngqo phakathi nezinsuku ezibandayo futhi zihlala emthunzini noma ngaphansi kwamanzi phakathi nezinsuku ezishisayo.
Ziyasebenza futhi zizingela kakhulu entwasahlobo nasekuqaleni kwehlobo, ezinyangeni ezibandayo zasebusika ziye zingasebenzi.
Bathola ukudla ebusuku nasebusuku. Umdlavuza utholakala ngokuhamba kwawo, ngokunemba okumangazayo, okunquma indawo yesisulu. Uma kwenzeka usongo empilweni, izinyoka zemigqa ezinemigqa zicasha ngaphansi kwamanzi. Ngokungafani nezinye izinyoka eziningi zikaRegina, kuyaqabukela zilume. Kodwa-ke, ezimweni ezikhethekile, izinyoka ezinemigqa ezinemigqa zikhipha ukukhishwa kwe-anal kusuka ku-cloaca. Ukukhishwa kwento enukayo kuyethusa ezinye izilwane ezincelisayo. Okokuqala, inyoka izama ukwethusa isitha, ivule umlomo kakhulu, inyakazise futhi igobise umhlane wayo. Ngemuva kwalokho kukhombisa indlela yokuzivikela ngokugoqa umzimba osontekile ube yibhola. Kulokhu, inyoka ifihla ikhanda layo ezihlangwini bese ibamba umzimba ezinhlangothini.
Ukondla inyoka yemigqa enemigqa.
Izinyoka ezinemigqa ezinemigqa yizona ezihuquzelayo ezikhethekile kakhulu ezidla ama-crayfish. Abantu abadala badla cishe kuphela izinhlanzi ezingama-Procambarus crayfish. Ngokungafani nezinye izinhlobo zezinyoka, izinyoka ezinemigqa ezinemigqa azikhethi ama-crustaceans esigabeni esithile se-molt yazo; bakhiqize ukuzivumelanisa komzimba nokusetshenziswa kwe-crayfish embozwe nge-chitin eqinile.
Izinhlobo ezimbili ze-crayfish ezihlala eFlorida zivame ukutholakala ekudleni - iProcambarus fallax neProcambarus alleni.
Ukudla kuqukethe ama-amphibian nezinambuzane ezifana namabhungane, ama-cicadas, i-isoptera, izintethe nezimvemvane. Izinyoka ezincane ezingaphansi kuka-20.0 cm ubude zidla ama-decapod crustaceans (ikakhulukazi ama-shrimps omndeni wasePalaemonidae), ngenkathi abantu abakhulayo abangaphezu kuka-20.0 cm ubude bechitha izibungu ze-dragonfly. Ukuqondiswa kwesisulu ngesikhathi sokudla kuncike kubungako besisulu maqondana nenyoka. Ama-decapods acutshungulwa nge-caudally, kungakhathalekile ubukhulu besilwane, kuyilapho ama-amphibian egwinywa kusuka ekhanda, ngaphandle kwezimbungu ezincane kakhulu, ezidliwa izinyoka ezisemsileni. Izinyoka ezinemigqa yabantu abadala zibamba i-crayfish ngesisu, zibeka inyamazane ngokweqile kugebhezi, kungakhathalekile ubukhulu bayo noma isigaba sayo se-molting.
Indima ye-ecosystem yenyoka yemigqa enemigqa.
Izinyoka ezinemigqa ye-Crayfish zidla izidalwa ezahlukahlukene. Bahlala njengesilwane esiyingqayizivele ezindaweni eziphila emanzini futhi badlala indima ebalulekile ekugcineni ukusimama kwemvelo. Zithinta inani le-crayfish, kuphela kulezo zindawo lapho ukuminyana kwezinyoka kuphakeme khona.
Kweminye imizimba yamanzi, izinyoka zemigqa ezinemigqa azidlali indima ekhethekile ekulawulweni kwabantu be-crayfish, ukubhujiswa kwayo kungaba nemiphumela emibi, ngoba ama-crustaceans, ngokudla i-detritus, adlala indima ebalulekile emjikelezweni wezakhamzimba ezinhlelweni zasemanzini. Izinyoka ezinemigqa ezinemigqa ziba yizisulu zezilwane ezidla ezinye, izinyoni, izilwane ezincelisayo ngisho ne-crayfish. Umdlavuza uvame ukudla izinyoka ezisanda kuzalwa. Izinyoka ezindala zizingelwa izinyoka ezinephethini, ama-raccoon, ama-otter emfula, izindwandwe.
Isimo sokonga senyoka enemigqa enemigqa.
Abantu benyoka yexhaphozi enemigqa babhekwa njengokuzinza kulo lonke uhla. Inani labantu eSouth Florida liyancipha ngenxa yezinguquko embusweni wamanzi kweminye imizimba yamanzi. Izinguquko ze-anthropogenic zithinta izindawo ezilungele inyoka enemigqa, ikakhulukazi ngenxa yokucekelwa phansi kwamahlathi aminyene ama-hyacinths asemanzini. Inyoka yexhaphozi enemigqa ilinganiselwe njenge-IUCN njengokukhathazeka Okuncane.
