Iyo ghost shark imhando inonakidza yanga iri nyaya yekufarira zvakanyanya kubva kune shark biologist uye hobbyists kwemakumi emakore akati wandei. Icho chikamu chemhuri yejecha shark, Scyliorhinidaeuye yakawana zita remadunhurirwa rekuti "ghost" nekuda kwekugona kwayo kusanganisa zvakakwana pasi pegungwa, uko kwakaoma kudziona.
Muchinyorwa chino, tichatarisa pane zvese zvinozivikanwa kusvika parizvino nezve ghost shark, kubva kwainogara kusvika kuhupenyu hwayo uye maitiro. Dzvanya nesu muruzivo rwe ghost shark: mugari asinganzwisisike wepagungwa rakadzika.
Chii chinonzi ghost shark?
The ghost shark ("Hydrolagus trolli") rudzi rwe shark mumhuri yejecha shark (Scyliorhinidae) iyo inogara mukatikati memakungwa, mugomba rakadzika-dzika uye bathypelagic zones.
Ichi chisikwa chisinganzwisisike chakashamisa masayendisiti kwemakumi emakore, chichisiya fungidziro nedzidziso pamusoro pekuvapo kwacho uye maitiro. Chitarisiko chake chechienzi chakamuwanira nguva yacho chimera, mukuwirirana nengano dzechiGiriki, sezvo yakasiyana zvikuru nedzimwe “hama” dzayo dzeshaki.
Anatomical features: imwe nyika chitarisiko
Chimwe chezvinhu zvinonyanya kufadza zvemhando iyi ndeyekutaridzika kwayo kwakasiyana uye kwakasiyana kunoisiyanisa kubva kune dzimwe shark. Ndicho chikonzero ivo vanonzi chimeras.
Muviri wayo wakarebesa uye musoro wayo une chimiro chakareba, chakati sandara, ine kamuromo kadiki kakazara nemazino akapinza, anonongedza. Maziso ayo makuru, ari kumagumo emusoro wayo, anopa zvinoshamisa uye, panguva imwe chete, anovhiringidza kuonekwa, achibvumira kuti ione mhuka dzayo munzvimbo dzakaderera.
Ganda rayo rakachenuruka, rinopenya rakaita kuti rive zita rekuti "ghost shark." Kujeka kweganda rayo chinhu chinoshamisa checamouflage sosi inoibvumira kuzvidzivirira kubva kune zvikara nekuenda kusingaonekwe munzvimbo yayo. Kunyange zvazvo zita rayo richiratidza kuti ishaki huru chena, ruvara rwayo chairwo igoridhe rerose, sirivheri, kana kuti shaki.
ghost sharks Vanogona kukura kusvika 1,5 uye 2 mamita kureba, iyo yakawanda inoenderana nemuswe wavo wakakura (dzimwe nguva dzinonzi "muswe wemakonzo"). Muzongoza une huturu uri pamberi pemushure unovabvumira kupinza uturu mumhuka ipi zvayo inovarwisa.
Mukupedzisa, tinogona kutaura kuti ghost shark chisikwa chine chitarisiko chinoshamisa kana chimeral, chisina kunyanya kufanana neshamwari dzayo dze phylogenetic, dzine zviduku zviduku uye zvikamu zvakasiyana zvakasiyana apo musoro wayo wakatsetseka uye muswe wakareba unomira kunze.
Habitat uye kugovera
the ghost shark Inowanikwa mumvura yakadzika yeAtlantic uye Pacific Oceans., uyewo muGungwa reTasman. Mhando yeshaki iyi inofarira kugara munzvimbo dzine mvura inotonhora, uko kunowanzo kutonhora kuri pakati pe7 ne12 ˚C.
Vanogara pakadzika 200 kusvika 2,000 metres, padyo nepasi pegungwa. Anogona kuwanikwa kazhinji mumakoni epasi pemvura uye munzvimbo dzepasi pemvura, uko ikozvino inoyerera zvishoma nezvishoma.
Ghost Shark Behaviour

Ghost sharks vane muviri mutete uye muswe murefu, zvichivabvumira kuti vakurumidze nekukasira kubata mhuka yavo. Mukuwedzera, vane mahwendefa emazino akapinza uye akasimba, izvo zvinovabvumira kubata uye kutsenga mhuka yavo zviri nyore.
Kufanana nedzimwe shark, ghost shark inofanirwawo kuzvidzivirira kubva kune zvikara, zvakadai semhondi whale uye dzimwe shark huru. Kuti uzvidzivirire, Iine maitiro ekudzivirira akavakirwa muganda rayo. vane zvipikisi zvinopinza pazvikero zvavo; Vanofemereka pavanotyisidzirwa.
Zvisinei nekutanga kuwanikwa muna 1898, ghost shark inoramba iri chirahwe kune vesainzi nekuda kwekushomeka kwayo uye kuoma kwekuidzidza. Kushaikwa kweruzivo uye zvienzaniso zvakatorwa zvakonzera kuti data zhinji pamusoro pemhando iyi ive yakavakirwa pane zvakawanikwa nemukana kana pamhuka dzakabatwa pamahombekombe.
Ghost Shark Hupenyu Kutenderera
Kunyangwe zvakawanda zvichiri kutsvagirwa muhupenyu hweghost shark, hezvino zvimwe zvinhu zvakawanikwa kusvika parizvino:
ghost sharks Dzinoberekana nekukandira mazai uye dzinenge dziine kanguva kekubereka. zvichienzaniswa nedzimwe shark. Hadzi inokwanisa kukandira avhareji yemazai gumi nemaviri panguva, izvo zvinotora mwedzi misere kuchechenywa. Kashoma kuti mazai achochonye asati aiswa, saka ghost shark hadzina pwere dzinorarama.
Kana mazai achinge achechenywa, maghost sharks echidiki anobuda, achidya pane zvipenyu zvidiki zvevhu uye achikura zvishoma nezvishoma.
Varume nevakadzi ghost shark vanosvika pakukura kwepabonde pazera remakore matanhatu kusvika kumakore manomwe, zvinoreva kuti vanogona kubereka makore maviri oga oga.
Mamiriro ekuchengetedza
Iyo ghost shark yakarongedzerwa se “Zvisina Kuongororwa” mhando neInternational Union for Conservation of Nature (IUCN). Izvi zvinoreva kuti hapana data rakakwana pamusoro pehuwandu hwayo kana mhedzisiro yezvakatipoteredza, saka hazvigone kuzivikanwa kana iri munjodzi yekutsakatika kana kwete.
Zvisineyi, ghost shark imhando isina kubatwa-hove ine nzvimbo yakasarudzika yakadzika uye kure kure zvekuti mhuka iyi inoramba yakadzivirirwa kubva mukunyanya-kushandiswa.
Dzidziso uye Zvokufungidzira
Kusaonekwa uye kushomeka kwezvienzaniso zvakawedzera dzidziso uye fungidziro nezvehupenyu nemaitiro eghost shark.
Mamwe masayendisiti anotenda kuti mhuka iyi inofamba yoga mukatikati megungwa, asi vamwe vanoti vanogona kuumba mapoka maduku. kana kutevera nzira dzisingazivikanwi dzekutama.
Nekudaro, kusvika zvino, hapana humbowo hwakakwana hwakaunganidzwa kuti husimbise chero yeiyi dzidziso uye ndosaka ghost shark, asinganzwisisike anogara mugungwa rakadzika, achiri kutariswa nhasi.
Dambudziko rekudzidza kwake: chisikwa chakafukidzwa nechakavanzika
Pasinei nematambudziko aanopa kudzidza kwake, masayendisiti anoenderera mberi achishanda nesimba kuti adzidze zvakawanda nezve ghost shark.
Kuburikidza nekushandiswa kwehunyanzvi hwepamusoro, vakakwanisa kuwana ruzivo rwakakosha pamusoro pemaitiro uye kugovera kwerudzi urwu. Zvisinei, zvakawanda zvichiri kuda kuwanwa. Hapana mubvunzo pamusoro pezvinorehwa neghost shark mumasikirwo: mugari asinganzwisisike wegungwa rakadzika.
