Iyo sawfish inorarama zvinoenderana nezita rayo. Muviri wayo wakareba uye muromo wakaita sekaona zvinoita kuti hove iyi ityiwe zvakanyanya. Zita resainzi ndi pristis pristis uye ndezvekurongeka kwePristiformes. Muchikamu chino tichaongorora iyi hove inoshamisa zvakadzama kuti udzidze zvakawanda nezvayo.
Iwe unoda here kudzidza zvese hunhu uye mararamiro eiyo sawfish?
Mhando huru
Mhuri ye sawfish ine magenera maviri uye manomwe marudzi. Ivo vakanyanya kana zvishoma zvine hukama nemitsara uye vanoratidzira mafupa azere nekartilage. Hunhu hukuru uye kune izvo zvinozivikanwa ndeyekuti tomu yakafanana nesaha. Iyo tomu inoputirwa mune yakawanda nhamba ye pores iyo inobvumidza iyo kuona chero kufamba kuti ikwanise kuvhima. Izvi zvinokupa mukana wakakura pamunda.
Simba rake rekunzwa rakakura zvekuti iyo inokwanisa kuona kurova kwemoyo kwechero mhuka. Mazhinji emabasa anoitwa nekuda kwemuromo mune saw mode. Inoshanda zvese kurwisa uye kudzivirira. Icho chishandiso chakanyatsonaka chakaringana icho chinogona kubata chibharo chekukurumidza kudya. Inoishandisa kuzvidzivirira kubva kuzvikara zvakadai semadhophini uye shark. Haina mazino, asi zviyero zvemeno.
Iyo tomu inoumbwa nemaviri 23 mazino izvo zvinopinda pamberi fungidziro. Yakakura kwazvo zvekuti inomiririra inopfuura kota yemuviri wayo. Vanogona kuenda kwakasiyana kunorwisa mhuka dzavanenge vakuvadza nesaha. Iyo yakafukidzwa zvakazara mune sensory pores iyo inokubatsira iwe kuona zvese zvakakukomberedza.
Sawfish inogona kuvhima munzira mbiri. Chekutanga kushandisa muromo wayo sebhurasho. Nenzira iyi, inogona kukwezva jecha kubva kunzvimbo dzakavharirwa senge makurustaceans, makamba uye shrimp. Inogona zvakare kuodza moyo mhuka yayo seyakatsemura mullet, uye mamwe mamodheru. Nekudaro, iri nyore kubatwa kwehark kana ivo vari vezera rehudiki.
Sezvavanokura, vanokwanisa kuzvidzivirira kubva kuzvikara zvinotyisa zvegungwa.
Maitiro
Iyo sawfish imhuka yemanheru, kunyanyisa uye vanopedza zuva ravo vachizorora zvine runyararo kuti vashande husiku nekuvhima. Kunyangwe paine chokwadi chekuti chitarisiko chavo chingaite senge chine njodzi uye chinomanikidza kutya, ivo hove dzinongoitika uye vasingakwanise kurwisa vanhu. Nekudaro, senge mhando zhinji, kana ikatyisidzirwa kana kurwiswa, haizeze kuzvidzivirira.
Imhuka yakangogara pasi inoshandisa yakawanda yenguva yayo kuzorora munzvimbo dzakanyarara. Inowanzoiswa padyo nevhu rejecha kwainogona kuwana mhuka pasi pejecha. Kufanana nemamwe ese emhando yavo, batoid elasmobranchs vanogona kufema vachishandisa hombe masirivhe avanayo mune rimwe nerimwe remaziso avo.
Habitat nenzvimbo yekugovera
Tinogona kuwana iyo sawfish munzvimbo dzinopisa uye dzinopisa. Vanowanikwa munzvimbo dzeAustralia, Africa, Ecuador, Portugal uye mune dzimwe nzvimbo dzeCaribbean. Vashanyi vanogona kuzviona sezvavanotora mvura isina kudzika.
Iyo inokwanisa kugara mune zvese zviri zviviri zvakachena uye zvine munyu mvura. Iwo anonyanya kuiswa mumiromo yenzizi umo musiyano wemvura nyoro uye munyu hausimbise metabolism. Kutenda kune hunhu hwehove idzi ivo vanokwanisa kushanda munzvimbo dzakasiyana dzemumvura. Vanogona kugara munzvimbo dzinovapa chikafu nerunyararo kuti vazorore mukati mezuva.
Ivo vanogona kuwanikwa mune mamwe estuaries uye mabhesi kwavanogara pasina kana kunetsekana. Iyo yakave yakasimbiswa pamwe neGulf yeMexico kumaodzanyemba kuburikidza neAtlantic nePacific. Mune dzimwe nzvimbo rinoshandiswa seimwe nzira yekurapa mune zvimwe zvirwere zvekufema.
Sezvo yakawanda yenguva yake achipedzera munzvimbo dzine madhaka uye jecha, anozvishandisa kuzvicherera nekuzvivaraidza. Kune izvi anoshandisa saha yake uye pazviitiko zvakawanda anopedzisira awana mhuka yekudya nayo. Izvo zvinoda kuziva kuti iye anogona kuonekwa achiita ichi chiito kungozvivhiringidza iye amene apo husiku hunodoka.
Chinyoro chakareruka chainacho hove dzinopisa, sezvo dzisina dziviriro yakanaka. Kugoverwa kwehove iyi kwakanangana nenzvimbo kwayakambogara muzvakawanda. Ivo vanogona kuwanikwa mumvura yeUnited States, kunyanya mune iyo yeNew York, Florida neTexas.
Sawfish kudyisa
Kudya kwavo kunobva pane yakakura invertebrates uye mollusks. Uye zvakare, inodyisawo zvimwe zvinhu zvipenyu zvinowanikwa mukudzika kwemvura. Kunyangwe pavanogovana nzvimbo imwechete uye sawfish ine kugona kuidya, haina kumboonekwa kuti yakadya hove dzematombo.
Paunenge uchida kubata hove iyi, haina kana matambudziko. Asi zvakadaro, Haina kudyiwa semamwe marudzi de peces. Ikozvino pane mamwe maonafish trades uye kunze kwenyika kuri kubudirira.
Kazhinji, kunwiwa kwehove iyi kunoitwa munyu uye inowanzo gara ichibatwa nefish shrimp. Huru hwakawanda hahuwanikwe sezvo isiri iyo chinhu chikuru chekuredza. Iine huwandu hukuru hwemekiyuri, saka hazvikurudzirwi kudya muzvikamu zvakakura. Ichi ndicho chikonzero nei chisina kuve chakakurumbira mune gastronomy yenyika.
Kuberekerwa
Hazvisi zvakawanda zvinozivikanwa nezve kubereka kwe sawfish. Izvo zvinozivikanwa ndezvekuti ivo vane ovoviviparous, saka mazai avo ekuberekera anokura mukati memukadzi kusvika panguva yeku hatch. Kana vasvitsa zera rinosvika makore gumi ndipo pavanosvika pakuzara zvakakwana. Kana vasina kubatwa nezvikara zvavo kana nevanhu, inowanzo kuve nehupenyu hunotarisirwa hwemakore makumi matatu.
Kuti vasvike pakukwana pabonde vanofanirwa kunge vareba mamita mana uye makore gumi ekuberekwa. Kubereka kwayo hakuna kunyanya kuwanda, izvo zvinoita kuti ive nenjodzi yekuredza zvakanyanya. Iyo yekuberekesa mwero weiyi sawfish yakadzika kwazvo uye inogona kufananidzwa neiyo seilfish kana marlin uyo anewo anononoka kubereka maitiro
Kubereka kunoitika mukati mwedzi waApril kusvika pakupera kwaJune.
Neruzivo urwu unogona kudzidza zvakawanda nezve sawfish. Wakazvida here? Ngatizivei mune zvakataurwa 🙂
