Muzvinyorwa zvakapfuura takataura nezvazvo White shark semumwe wemhuka dzinotyisa mumakungwa. Nhasi tauya kuzokuudza imwe nezve shark. Mune ino kesi isu ticha taura nezvayo nzombe shark. Kunyangwe musimboti zita iri risinganzwike zvakanyanya, ndeimwe yeanowanzo shark anogara mumahombekombe uye nyanza dzeLatin America. Zita rayo resainzi ndi Carcharhinus leucas.
Kana iwe uchida kuziva zvese hunhu, kufudza, pekugara uye kubereka kweiyi shark, iyi ndiyo yako posvo.
Mhando huru
Kune akawanda kuona kweiyi shark munzvimbo zhinji. Iwo ari nyore kwazvo kufamba-famba mugungwa uye iwo akawandisa. Unogona kufamba ese manyoro uye ane munyu mvura uye zvese nzizi nemadhamu muCentral America neAmazon.
Muviri wacho une zvimbi zviviri zvakakura zvemashure uye muswe wakareba nehurefu hwakareba hwepamusoro uye bhiri rekufungidzira. Unogona kuwana makopi e kusvika pamamita angaita 3,2. Paavhareji varume vanoyera 2,1 metres uye vakadzi 2,2 mita. Izvo hazvisiyane zvakanyanya muhukuru. Ruvara rwayo ndere grey mumuviri wese, kunze kwechikamu chepamusoro chiri chichena.
Iyo mhando ine hukasha yemumvura uye inofungidzirwa pakati pemarudzi makuru e shark. Huremu hwako hunodzikira pakati pe 90 ne 200 kilograms. Dzakanyanya kurema kazhinji dzakareba. Kunyangwe vanhu vachitenda kuti chena shark ndiyo mhuka inotyisa mumakungwa, hazvina kunaka. Iyo nzombe shark inogona kuve inowanzo kurwisa vanhu.
Muviri wayo wakasimba uye wakakora, uine mapini akareba. Kana vari vadiki vane nzvimbo dzakasviba uye dzvuku pamativi. Kana ari mazino (akakosha chinhu munyika ye shark) isu tinowana iwo akakura saizi, yakapinza uye yakareba. Shaya dzakasimba kwazvo, kunyangwe maziso ayo ari madiki zvakanyanya maererano nemuviri wake wese.
Inowanzo kuratidza chiito chakakasharara uye hunhu hunorwisa. Kana dzikarwisa, dzinoita kudaro nekutenderedza nyama yadzo kakawanda. Vachave vakaita seizvi kudzamara vazadzikisa chinangwa chavo. Ivo vakajairwa kurwisa vanhu, saka chenjedzo yakanyanya inofanira kuitwa navo.
Kugovera uye pekugara
Nguruve shark inogona kuwanikwa muRwizi rweAmazon muSouth America, Zambezi (ndosaka ichinziwo Zambezi shark) uye Limpopo muAfrica, muLake Cocibolca muNicaragua neGanges kuIndia.
Nezvekugara kwavo, idzi mhuka dzinofarira kufamba-famba nzvimbo dzavari padyo nemabhichi kana mahombekombe. Nenzira iyi, ivo vanokwanisa kuwana yakakura kwazvo mhuka yekudya kuti vadye. Aya mashark anowanikwa munzvimbo dzese dzegungwa kutenderera pasirese, kwete muSouth America chete, asiwo muPacific, Atlantic neIndia Oceans.
Idzo mhuka idzo, kazhinji, dzinowanzo gara munzvimbo imwechete kubva pakuberekwa kusvika parufu. Zvisinei, inogona kunge iri nyaya yekuti vanofamba vachienda kumatunhu marefu. Zviratidzo zvakave zvichionekwa munzvimbo dzenzizi nemadziva emvura uko, kusvika, vakafanirwa kufamba makiromita zviuru zvitatu kumusoro.
Bull shark kudyisa
Iyo nzombe shark inodya marudzi ese emhuka. Uku ndiko kufara kwavo mukudya kwavanokwanisa kudya mamwe mashaki. Siwe kudya kunodya zvachose. Dzine njodzi kuvanhu, nekuti nzvimbo yavanotsvaga iri padyo nenzvimbo dzekugezera.
Kugona kwavanogona kupinda mumvura yakachena mushure mekuuya kubva munyu kuri kuburikidza neshinda yakakosha iri muitsvo. Iyi gland inovabvumidza kuve nemvura yemunyu mumuviri wavo uye kudzinga mvura nyowani. Izvi zvemamwe marudzi eshark zvingave zvinouraya. Mvura nyowani inokonzeresa kuti masero eshark anogara mumvura dzegungwa aputika uye aunze kurufu. Nekuda kweiyi gland, iyo bhuru shark inogona kuswedera padyo nenzvimbo dzevanhu.
Kubereka uye vana
Shark iyi inozivikanwa kunge imwe yemhuka dzine mwero wepamusoro we testosterone mumwaka wekukwira. Unogona kuva nazvo yakawanda yehomoni iyi kupfuura nzou yechirume yeAfrica. Munguva yekukwira inowedzera zvakanyanya, izvo zvinoita kuti ive mhuka ine nharaunda.
Kubereka kwe bhuru shark zvakangofanana neakawanda emamwe mammalia. Nekudaro, ine hunhu hwakasarudzika kubva kune hwedzimwe mhando. Icho ndechekuti vakadzi vane uteri maviri. Izvi zvinozivikanwa se intrauterine cannibalism.
Mazai madiki ari kukura mukati mawo anokwanisa kupa chikafu kune avo vevanin'ina kana mamiriro ari kushomeka mune zvinovaka muviri. Iko kubata kwevechidiki kazhinji kunotora pakati pemwedzi misere negumi. Ino nguva inodikanwa kuti vechidiki vakure zvakanaka uye vakwanise kuzviriritira kana vasiya amai.
Vakadzi chete vane kugona kubereka vana vadiki munguva yemakore maviri uye maviri chete panguva. Naizvozvo, inofungidzirwa semhando ine kunonoka kubereka.
Zvinotyisa chikamu
Rudzi urwu haruna kunyorwa senjodzi neInternational Union for Conservation of Nature (IUCN). Kana vari munzvimbo dziri pedyo nevanhu vari panjodzi yekuredza uye shanduko yezvakatipoteredza izvo zvine hukama nekugadziriswa kwenzvimbo. Kuvakwa kwedhamhu, kurima uye indasitiri kunogona kuve makuru maekisheni ezvinokanganisa pane zvipenyu. Iko kushandurwa kwenzvimbo yechisikigo kunogona kuve chikonzero chekuti idzi shark dziiswe seNjodzi.
Pachivanhu, nzombe shark dzinobatwa hove dzekutengesa ganda ravo, nyama uye chiropa mafuta, kunyange hazvo nhasi, iyo IUCN inocherekedza, zvimbi zvavo ndizvo chikuru chigadzirwa chinotyaira chinodikanwa cheichi uye nezvimwe zvakawanda zvemarudzi.
Neruzivo urwu iwe unozogona kudzidza zvakawanda nezve idzi shark dzinoonekwa sedzine njodzi kuvanhu.
R. Zvakanaka, kana iwe uchizotaura nezve bhuru shark, nei mifananidzo miviri yekutanga yeGaleocerdo cuvieri neCarcharhinus plumbeus?
Handizive kana iwe uchiziva kuti iyo pikicha iwe yawakashandisa yakafanana iyo yakaburitswa mu http://www.hablemosdepeces.com
Zvichida ndeimwe yeaya emahara mafoto kana ivo vakauteedzera kana iwe wakazvitora kubva kwaari. Zvakaitikawo kuti imi mese makanganisa mukumukanganisa ingwe.
Iyo ine mbiri hombe dzeshure
A. Iyo haina huru yekumashure mapini, sailfish inoita.
