Pakati pemhuka dzinowanikwa munzizi isu tine al Rwizi gakanje. Iyo decapod arthropod ine muviri wakafukidzwa nehombodo. Iyi goko inoonekwa seyakare uye inoshanda kuzvidzivirira. Izvo hazvina kufanana nesu, pachinzvimbo chekuva nemapfupa mukati, anayo nekunze. Mune gastronomy, crab nyama iri kudiwa zvakanyanya uye izvi zvinoreva kuti kuvapo kwayo kunogona kutyisidzirwa.
Muchikamu chino tichaudza iwe nezve hunhu uye mararamiro e crayfish kuti udzidze zvakawanda nezvazvo.
Mhando huru
Exoskeleton iyo yakafukidzwa nayo yakaoma kwazvo uye inoshanda kuzvidzivirira pachayo. Iyo inoumbwa zvakanyanya necalcium. Inopa muviri wese wakakamurwa kuita zvikamu zvinoitendera kuti ifambe uye kutenderera nzvimbo dziri mukati merwizi. Zvikamu zvikuru ndezvekunze uye kumashure, inonziwo cephalothorax uye mudumbu. Muchikamu chekutanga pane musoro uye thorax yakaparadzaniswa nekervical sulcus.
Kune rumwe rutivi, isu tine iyo yecapapace yakareba mukuwedzera uko maziso anoiswa. Muromo waro unoiswa pachikamu chemusoro wemusoro uye chakakomberedzwa nemakumbo anobatsira mhuka kuitisa kufamba.
Iyo autochthonous crab inowanikwa munzizi munzvimbo dzese peninsula uye dzinowanzo kuve nyore kusiyaniswa sezvo dziine mashanu maviri emakumbo pamativi uye munzvimbo yemukati yeiyo cephalothorax. Makumbo maviri ekutanga akanyatsogadzira nzwara dzinoshandira zvese kudzivirira uye kutora chikafu. Zvichida uyu nzwara unoita kuti magakanje ave hunhu uye kwaanozivikanwa.
Iwo maviri anotevera mapaundi emakumbo anewo anosunga asi ari mashoma kwazvo muhukuru kupfuura yekutanga. Yokutanga ndiyo inonyanya kukosha uye inobatsira kumhuka. Iwo maviri ekupedzisira maviri emakumbo ane nzwara yavanoshandisa kubata chaiyo uye kugadzikana pavanofamba.
Zvese zviviri zvemakumbo zvinoshandiswa kufamba kusara kwekutanga, iyo inogara yakagadzirira kuzvidzivirira kana kurwisa mhuka.
Muviri unoshanda
Iyo kanyanga dzakarongedzwa kumagumo kwechiso uye zvakare ine mamwe madiki antellenule. Aya maantena ane chinoshandiswa kuve nhengo iyo yaanoenderana nayo nharaunda uye ane basa rekunzwa. Uye zvakare, inoshanda kuchengetedza yakanaka chiyero uye kugona kunzwa zvese zvakavatenderedza.
Nzira yekufema inoshanda nekutenda kumakomba ayo iine mumakamuri maviri akarongedzwa pamativi ese emukati ane cephalothorax. Dumbu rayo rinewo zvikamu zvitanhatu zvinogona kuchinjika uye zvine mapenduru. Aya maappendage ari biremean uye akanyatsogadzirwa. Muchikamu chemagumo etelson isimba rekushambira rine muswe. Izvi ndizvo zvinoita kuti crayfish inyatsoshambira uye inokwanisa kufamba nyore kunyangwe rwizi rwune magetsi ane simba.
Iko kugona kwegakanje kunofanirwa kunge kwakakwana kuti urarame munzvimbo dzine mvura yemvura yakasimba. Semuenzaniso, kana paine mvura yakasimba, rwizi kuyerera kunowedzera zvakanyanya uye makungu anofanira kunge akagadzirira kurarama mumamiriro ezvinhu aya.
Kana iri yekugaya system, yakangwara kwazvo. Kubva kunze iwe unogona chete kuona iyo anus iri mune ye ventral chikamu cha telson.
Nekuda kwekusiyanisa makara echirume neechikadzi, kumwe kupesana kunofanirwa kusimbiswa pakati penzvimbo dzepabonde. Muvanhurume, maburi aya anovhurika munzvimbo dzekutanga dzemakumbo ekupedzisira uye nhengo yekumanikidza inowanikwa mumaviri maviri ekutanga. Mumadzimai, zvidzitiro zvebonde zviri pamakumbo echitatu uye mamwe acho anogona kuderedzwa kana kusavapo.
Nzvimbo yekugara
Iyo crayfish haina kunyanya kuda maererano nemamiriro ezvinhu ainoda kurarama. Iyo inogara mumvura dzese dzenzizi dzeSpain dzine kuyerera kwakaringana. Kunyangwe isinganyanyo kumanikidza, inosarudza kuti mvura dzakapfuma muma calcium salts kuitira kuti isimbise exoskeleton yayo uye huwandu hweakisijeni yakanyangarika pakati pe3 ne12 mg / l.
Nezve kutonhora, Ivo vanofanirwa kuve mune iyo 8,5-22 degree degree. Iyo crayfish inoshanda seyakanaka nharaunda chiratidzo chehunhu hwemvura dzine nzizi dzedu, nekuti kana dzakashatiswa hatizoadziona. Kunyangwe iine simba rekumira nemimwe mafungu ane simba, isu tinowanzoaona achigovaniswa munzvimbo dzinomhanyisa mvura. Pazasi perwizi panogona kuchinja uye kuve munzvimbo mbiri dzisina kudzika uye mune dzimwe dzakawanda.
Haafarire nzvimbo dzakajeka saka anotora mukana wekuhwanda muhuswa hwenzizi. Dzimwe nguva nemapuri ayo anogona kuita gomba nekuchera kana ichinzwa kutyisidzirwa. Iyo inogona zvakare kuvanda pane mamwe mabhengi materu kana pasi pematombo mahombe.
Basa rayo repamusoro rinoitika husiku uko mwenje hauiti kuti iwanikwe neyakaibata. Iyo nguva yegore painenge ichinyanya kushanda iri pakati pechirimo nematsutso, zororo regore iri iri kuhope mune imwe yenzvimbo dzayo dzinowanzo chengeteka dzakachengeteka.
Kupa uye kubereka kweye crayfish
Aya makamba anodya dzinenge zvese. Sanganisira mukudya kwako hove diki, kuora kweimwe mhuka, amphibian maruva, macroinvertebrates, zvinomera zvemumvura uye kunyangwe algae. Pakati pezvikara zvakakosha zvaunofanira kutarisa kune zvipembenene zvecoleopteran uye odonata, dzimwe hove hombe, shiri uye zvimwe zvipuka zvakaita se otter.
Nezve kubereka kwayo, mwaka wekubereka unotanga kusati kwasvika panguva yechando umo mukadzi inokwanisa kuisa pakati pemazai makumi mana kusvika makumi masere pasi pemimba uye yakagadzika pamakumbo ayo. Inozvidzivirira pavanenge vachibanda kusvikira mazai achinge anouya chitubu chinotevera.
Ndinovimba kuti ruzivo urwu runobatsira kudzidza zvakawanda nezve crayfish yatinayo muPeninsula.
