Phakathi kwezilwane ezitholakala emifuleni sinalo al Inkalankala yoMfula. Kuyi-decapod arthropod omzimba wayo umbozwe yigobolondo. Leli gobolondo lithathwa njengesiphephelo futhi liyazivikela. Akufani nathi, esikhundleni sokuba namathambo ngaphakathi, anawo ngaphandle. Ku-gastronomy, inyama yenkalankala iyadingeka kakhulu futhi lokhu kusho ukuthi ubukhona bayo bungasongelwa.
Kulesi sihloko sizokutshela izici nendlela yokuphila ye-crayfish ukuze ufunde kabanzi ngayo.
Izici eziyinhloko
I-exoskeleton embozwe ngayo inzima impela futhi isebenza ukuzivikela. Iqukethe ikakhulukazi i-calcium. Yethula umzimba wonke uhlukaniswe waba izingxenye eziwuvumela ukuba unyakaze futhi uzungeze izindawo ezingaphakathi emfuleni. Izingxenye eziyinhloko zingaphambili nangemuva, okubizwa nangokuthi i-cephalothorax nesisu. Engxenyeni engaphambili kunekhanda nesifuba esihlukaniswe yi-sulcus yomlomo wesibeletho.
Ngakolunye uhlangothi, esinayo ye-carapace eyandisiwe isandiso lapho kufakwa khona amehlo. Umlomo wayo ubekwe engxenyeni ye-ventral yekhanda futhi uzungezwe yimilenze esiza isilwane ukuthi sinyakaze.
Inkalankala e-autochthonous itholakala emifuleni kuyo yonke i-peninsula futhi imvamisa ihlukaniswa kalula njengoba inamabhangqa amahlanu emilenze ezinhlangothini nasendaweni ye-cephalothorax. Imilenze emibili yokuqala ithuthukise uzipho olusebenzela ukuvikela nokubamba ukudla. Mhlawumbe yilo uzipho olwenza izinkalankala zibe yisici futhi ezidume ngazo.
Imilenze emibili elandelayo nayo inezibopho kodwa incane kakhulu ngosayizi wokuqala. Owokuqala abaluleke kakhulu futhi awusizo esilwaneni. Imilenze emibili yokugcina inezinzipho eziyisebenzisela ukubamba okufanele nokuzinza lapho zihamba.
Zonke izinyawo zemilenze zisetshenziselwa ukuhamba ngaphandle kowokuqala, ohlale ukulungele ukuzivikela noma ukuhlasela inyamazane.
Ukusebenza komzimba
Izimpondo zihlelwe ekugcineni kobuso futhi zinezinhlayiya ezincane ezincane. La ma-antenna anokusizakala kokuba yilungu lokuzivumelanisa nemvelo futhi abe nomsebenzi wezinzwa. Ngaphezu kwalokho, kuyasiza ukugcina ibhalansi yakho kahle futhi ukwazi ukuzwa konke okuzungezile.
Uhlelo lokuphefumula lusebenza ngenxa yamaphaphu enawo emakamelweni amabili ahlelwe ezinhlangothini zombili zomgodi onayo i-cephalothorax. Isisu saso sinezingxenye eziyisithupha ezingashintshwa futhi sinezihlanganisi ezimbili. Lezi zithasiselo zenziwe nge-biremean futhi zithuthukiswe kahle. Engxenyeni yokuphela kwetelson kunomsila onamandla wokubhukuda. Yilokhu okwenza i-crayfish ibhukude kahle futhi ikwazi ukuhamba kalula yize umfula unemisinga eqinile.
Umthamo wezinkalankala kufanele wenele ukuze uphile ezindaweni lapho umsinga wamanzi unamandla khona. Isibonelo, lapho kunezimvula ezinamandla, ukugeleza komfula kukhuphuka kakhulu futhi izinkalankala kufanele zikulungele ukusinda kulezi zimo.
Ngokuqondene nesistimu yokugaya ukudla, ihlakaniphe kakhulu. Kusuka ngaphandle ungabona kuphela ingquza esengxenyeni ye-telson yangaphakathi.
Ukuze uhlukanise izinkalankala zabesilisa nabesifazane, umehluko othile kufanele usungulwe phakathi kwama-orifices ezocansi. Kwabesilisa, le mibobo ivuleka ezingxenyeni ezingaphansi zemilenze yokugcina nasemabhangqwaneni amabili okuqala isitho sokukopisha sitholakala. Kwabesifazane, ama-orifices ocansi asemilenzeni yesithathu kanti eminye incishisiwe noma ayikho.
Indawo yemvelo
I-crayfish ayifuni kakhulu ngokwemibandela edinga ukuhlala kuyo. Ihlala kuwo wonke amanzi emifula yaseSpain anokugeleza okwanele. Yize ingafuneki kakhulu, ikhetha ukuthi amanzi acebile ngosawoti we-calcium ukuze kuqiniswe izingqimba zawo inani le-oxygen encibilikisiwe phakathi kuka-3 no-12 mg / l.
Mayelana namazinga okushisa, Kudingeka babe sebangeni eliphakathi kuka-8,5 no-22 degrees. I-crayfish isebenza njengesibonakaliso esihle semvelo sekhwalithi yamanzi imifula yethu enayo, ngoba uma ingcolisiwe ngeke siyibone. Yize inamandla okumelana neminye imisinga enamandla, ikakhulukazi siyibona isatshalaliswa ezindaweni lapho ijubane lamanzi lihamba kancane kakhulu. Iphansi lomfula lingashintsha futhi litholakale ezindaweni ezingashoni nakwezinye izindawo ezijulile.
Akazithandi izindawo ezigqame kakhulu ngakho-ke uthatha ithuba lokucasha ezimileni zemifula. Kwesinye isikhathi ngezihlakala zayo ingenza umgodi ngokumba uma izizwa isongelwa. Ingabuye icashe emithambekeni ethile yasebhange noma ngaphansi kwamatshe amakhulu.
Umsebenzi wayo omkhulu wenzeka ebusuku lapho ukukhanya kungakwenzi ukuthi kutholakale isisulu saso. Isikhathi sonyaka lapho sisebenza khona kakhulu siphakathi kwentwasahlobo nasekwindla, unyaka wonke usekuhosheni kwenye yezindawo zawo zokucasha ezivame kakhulu.
Ukondla nokukhiqiza kabusha i-crayfish
Lezi zinkalankala zidla cishe yonke into. Faka ekudleni kwakho inhlanzi encane, isidumbu sezinye izilwane, izibungu zasemanzini, ama-macroinvertebrates, izitshalo zasemanzini kanye ne-algae. Phakathi kwezidliwayo ezibaluleke kakhulu okufanele uziqaphele kunezinambuzane ze-coleopteran ne-odonata, ezinye izinhlanzi ezinkulu, izinyoni nezinye izilwane ezincelisayo ezifana nama-otter.
Mayelana nokuzala kwayo, inkathi yokuzala iqala ngaphambi kokulala lapho insikazi iyakwazi ukubeka phakathi kwamaqanda angama-40 kuya kwangama-80 ngaphansi kwesisu futhi imiswe emilenzeni. Iyayivikela ngenkathi ifukamela kuze kube yilapho amaqanda echamusela intwasahlobo elandelayo.
Ngiyethemba ukuthi lolu lwazi lusiza ukufunda kabanzi nge-crayfish esinayo enhlonhlweni.
