Shaka yekakari inopfuura dino - imwe yezvikara zvinotyisa

Makungwa nemakungwa epasi redu azere nezvisikwa zvakasiyana-siyana, izvo upenyu hwavo hwakavanzwa kubva kwatiri pasi pemvura. Mumwe wevamiriri vehupenyu hwemhuka iyi ibamba re catarrhizal uye nhengo dzaro: cigar Isistiuslabialis (Brazilian) uye Isistiusplutodus (South Chinese) sharks. Zvose zviri zviviri zvinobva kumusana weIsistius, avo vamiririri vakazviratidza kuti vakaoma, zvinotyisa, nenzira yekushungurudza yekuvhima nyama.

Kunze, vamiririri vejenasi vakaita zvakafanana kune imwe, pakati pavo chete shark inobhururuka inomira kunze, yakasiyana nejaya riri pasi, rakazara nemazino makuru, akacheka. Mumuviri wake unopenya murima rakati rima uye une chimiro chegodya, naizvozvo zita-cigar shark. Mufananidzo wehove inopenya ine maziso makuru inogona kuonekwa pasi apa. Iyi shark inonyatsobatanidzwa neCuban cigar.

Habitat

Mvura inopisa yemakungwa ose, shark iyi inofunga nezvezvinhu zvayo zvokuvhima. Hove haingararami mumvura chete kumativi ekuchamhembe. Mvura yakadzika yekushambidzira yakanyorwa zvikara zvinenge zvakadzika kupfuura mamita 3000, ichicherechedza kufamba kwavo nguva dzose usiku pamusoro pemvura. Nekusvika kwezuva, cigar shark yakadzika kusvika pakadzika, ichikunda kure nemakiromita matatu.

Kubata midziyo inobatwa zvikara mumvura yakadzika yeAfrica, Brazil, Australia, maHawaiian Islands uye Tasmania.

Kuonekwa

Nechitarisiko chakangwara uye kureba kusingasvika 60 cm, cigar shark inogona kuzvirumbidza pamusoro pekuvapo kwemazino akadaro, izvo zvisiri kunyange chichena chikuru.

Ihove iyi ine maitiro ayo:

• Chimwe chitunha chakafanana nemutumbi;
• Pamusoro wepamusoro wepamusoro kune maziso maviri emuarimondi akaumbwa nemafungiro anokwanisa kubudisa chiedza chemavara, chinoita kuti mumiriri wegungwa zvive muvhimi anoshanda;
• Wakangwara mutsvuku wakaoma, uchibvumira mhuka kuti iyanane nemuvara wemvura;
• Kukwanisa kwemuviri kuti kuve nechiedza chine ruvara, pane zvose zvingave, kwakagadzirirwa kutengesa mhuka inopambwa;
• Vagadziri vane muromo wakavharwa vanoshambidza magetsi avo uye vanofema, vanoramba vari mumamiriro ekusaziva; Uku kukwanisa kunodiwa kuti vatsvake;
• Sezvo chimbo chikuru, cigar shark inoshandisa mazino akasiyana-siyana ari pamusana wezasi: vane maitiro akaita saka yakafanana nemasona ane zvigunwe zviduku zvisingatauri; Mazino emutsara wepamusoro madiki zvikuru kudarika pasi.

Muridzi wejaya rine simba

Iyo cigar shark huru-inoted inonzi inofanirwa muridzi wejaya rakasimba kwazvo. Achishandisa bhakombipop nemiromo, akayamwisa kune uyo akabatwa uye, achichera mukati memaviri ake, akacheka zvidimbu zvenyama paaifamba achizvikomberedza. Zvisikwa zvenyama hove huru, mhuka dzegungwa dzinodzingwa nemhuka dzinoparadza kubva mumuviri wezvokudya. Mushure mekurwa kwakadaro kwemuviri wevagari vakura vegungwa ikoko kune utsinye, hurefu kwenguva refu maronda ane zvinyorwa zvese. Zviratidzo zvakadaro zvakawanikwa kanopfuura kamwe mumaketesi nema dolphin. Kana boka richibatana mukurwiswa, zvino munhu anenge atambudzwa, sekutonga, achaparadzwa.

Kudzingirira maitiro

Kukwanisa kubatanidza matama uye kuvhara mashizha emagetsi kunoita kuti zvikwanise kugadzira chinyoro mumuromo wemumuromo, izvo zvinokubvumira kubatana zvakasimba mumuviri wezvakapambwa, zvishoma nezvishoma kugunzva nenyama yayo. Kana kubatwa kwaiye akabatwa, iyo cigar shark haisununguri pasi pasi pemamiriro ose. Iyo hove muvhimi akanaka, saka mhondi haigoni kupukunyuka kubva kumazino ayo akacheka.

Zvichienda kune mumwe munhu anenge aine chiremera chikuru kwazvo (a whale, mutsipa, hove huru, dolphin), akakurumidza kunwisa mumuviri wake, achibaya mazino ake makuru. Nguva pfupi iyo yakabatwa, iyo cigar shark inoshandisa mitsetse yakaderera, inokanda chimedu che nyama uye inokurumidza kushambira. Nguva yekutonga kwose inotora mashomanana mashomanana chete, uyo anenge achinetseka haana kunyange nguva yekuwanazve, sezvaanoramba ari neronda. Nyanzvi dzinobvumirana kuti 70 kusvika ku80% maronda pamuviri wemhuka akasara ane guru guru rakashata.

Chizvarwa chevana

Kuberekwa muhove kunotora kuburikidza nekutakura mumuviri we embryo. Vana vaduku vanozvarwa vakagadzirwa shaka, iyo inenge yakasvika masendimita makumi mashanu nemasere. Kuberekwa vana kubva mumazuva okutanga ehupenyu kunokwanisa kuzvipa ivo pachavo. Ichokwadi kuti haisi mhuka dzose duku dzinopukunyuka, dzimwe dzikava mhuka dzezvikara, asi avo vanopukunyuka vanoramba vachivhima, vachiwana hupenyu hwavo nekucheka zvidimbu zvenyama kubva kune vamwe vanogara mugungwa.

Chokwadi chinofadza

Kune zviitiko apo mhondi yekasi shark yakarwisa vanoda scuba diving.

Muna 2009, kuruma kwakanyorwa muHawaii, kurwisa kwakaitwa nekushambira Michael Spalding.

Vhidhiyo yakanyora pamusoro pekudzokidzwa kwehove uko vanhu vakaputsika ngarava vakagamuchira.

Usazvidza cigar shark nekudzivirira mafaira pasi pemvura bathyscaphes, nyore nyore kugunzva uye rubha shaathing.

Muna 2012, pakanga paine nyaya apo mumvura yehove yePacific toothy yakavhiringidza inflatable gondola yevafambisi vezvikepe vaideredza nyika. Chiitiko chacho chakaguma zvakanaka, nzvimbo yokushambi yakagadzirwa, uye kufamba kwakaramba kuripo.

Vamiririri veToothed vanozivikanwa zvikuru mumvura yegungwa nemakungwa zvokuti sangano rekuchengetedza haina kumboona zvakakosha kuisa mhuka idzi pane urongwa hwevaya vanoda kubatsirwa.

Shekisi haifariri mukurumbira. Hazvina kubatwa kana kushandiswa mubhizimusi wekubata hove.

Vamiririri vezvipenyu vane kukwanisa kukura mazino akarasika. Nokudaro, kuverenga kangani munguva yehupenyu kune zvitsva zvitsva zvekuvhima, zvinenge zvisingaiti. Kurasikirwa kweimwe "chigadzirwa" hakugadziri chibereko chekuvhima, mazino e shark, akarongwa mumitsetse, achipa mukana wekubata chibharo sechisimba. Mumazuva maviri "itsva" itsva ichakura.

Sezvo mutemo, vamiririri veIsistius vachivhima, vakaungana mumapoka maduku, vanoshambira usiku usiku hwemvura.

Mvura isina kudzika, shoals kusangana nehomwe yevashandi haigoni. Nokudaro, kutyisidzira kune vanoita mazororo vanobatanidzwa mumitambo yemvura, hazvirevi.

Sharks inorarama mumadziro emvura epasi redu kwemakore makumi mana emakore. Uye nhasi maitiro avo anoshamisika uye anotyisa vanhu. Nguva yehupenyu hwavo hunosvika makore makumi maviri nemakumi matatu.

Kana iwe uchidavira zvinyorwa zveJapan, sharki inotora mweya yevatadzi mugomba risina chigadziko.
