Kwayedza nyowani yekutsvaga kuti hupenyu hwerudzii huripo pagungwa hwakamutsa fungidziro nezve tarisiro yechikara chakakura chaizvo chakavanda munzvimbo dzakadzika dzerwizi. Iyo hombe shark kana hombe squid? Kana chimwe chinhu chinotyisa kupfuura isu chatingafungidzira?
Saka zvakadaro, isu tangotarisa kwakatenderedza 5% yemakungwa epasirese, ayo anofukidza 70% yepasi repasi. Vanhu vagara vachifadzwa nezvakavanzika zviri mukati kati memvura.
Kuedza kukuru kweGator
Apo nyanzvi dzezvipuka zvegungwa Craig McClain naClifton Nunnally vanobva kuLouisiana Universities Marine Consortium vaida kuwana nzwisiso irinani yezviri kuitika pasi pegungwa, vakaita chiedzo chinozivikanwa se Great Gator Kuedza, izvo zvakaburitsa zvimwe zvinonakidza.
Vatsvakurudzi vakanyudza buffet yezvisikwa zvisinganzwisisike zvegungwa izvo zvaisanganisira matatu akafa macaligator, aine zvisungo zvakasungirirwa kwavari. Vakanga vachida kuziva kuti zvitunha zvavo zvaizopedzwa sei nezvisikwa zvakavanda pasi pegungwa.
"Kuti tiongorore dandemutande rekudya mukati megungwa, takaisa nguruve dzakafa dzinosvika mazana matanhatu nemazana matanhatu pasi muGulf yeMexico kwemazuva makumi mashanu nerimwe," akadaro Clifton Nunnally anobva kuLouisana University.
Izvo zvakatevera zvakashamisa zvikuru
Gator yekutanga yakapedzwa mukati memaawa makumi maviri nemana ekurova pasi pegungwa. Yakagamuchirwa ipapo nehofori isopods, iyo zvinoenderana neNunnally, yakafanana nemagungwa akadzika-egungwa. Zvino, vamwe vanotsvaira vakaita samaamphipods, magrenadier uye zvimwe zvakavanzika, hove dema dzisingazivikanwe dzakapinda mumutambo uyu. Isopods dzakabvarura reptile nekukurumidza kupfuura zvaitarisirwa nemasayendisiti, vachidya mukati nekunze.
Nguruve yechipiri yakadyiwa mukati menguva yakareba yenguva. Mushure memazuva makumi mashanu neshanu, zvese zvakasara paari mafupa ayo, aive neruvara rutsvuku.
“Iye akatishamisa zvechokwadi. Pakange pasisina kana chikero kana scute chakasara pamutumbi, ” McClain akaudza Atlas Obscura. Chikwata chakazotumira mafupa kuna Greg Rouse, nyanzvi yemugungwa kuScripps Institution of Oceanography, kuti aongororezve.
Rouse akawana kuti iyo gator yakanga yadamburwa kuita zvisungo zvepfupa nerudzi rutsva rwehonye dzinodya mabhonzo muiyo Osedax genus. Iyi yaive nguva yekutanga kuti nhengo yeOsedax iwanikwe muGulf yeMexico, sekutaura kwaMcClain. Vatsvakurudzi vakabva vaenzanisa iyo DNA ichangowanikwa kune iya yeaya akatozivikanwa marudzi eOsedax, uye vakaona kuti vawana mhando yemhando yeiyo genus.
Kunyangwe paine kuwanikwa kunoshamisa kwechisikwa chitsva cheOsedax, yaive yechitatu nguruve yakasiya vesaenzi vashamisika zvikuru. Pavaishanyira saiti pakadonhedzwa gator rechitatu, vaingoona kushushikana kukuru mujecha - mhuka yakanga yanyangarika zvachose. Chikwata chakazotsvaga nzvimbo yakatenderedza asi havana kuwana mutsindo weaigarigori. Nekudaro, ivo vakawana huremu hwakanamatira kune iyo gator, iyo yakanga iri pamusoro pe 10 metres kure nenzvimbo.
Zvinoreva izvi ndezvekuti chikara chakatsvaira gator chakange chakakura zvekuchidya chose uye nekukweva huremu hwakanamatidzwa kweimwe nhambwe. Chikwata ichi chinofungidzira chisikwa ichi kunge chihombe squid kana hombe shark yakamirira kuwanikwa. "Handisati ndatsvaga squid inogona kudya alligator yose, uye handidi kuva mungarava kana tikazoiwana."
Vaviri vaongorori vakavhunduka nezve mhedzisiro, uye zvakare vakagutsikana kwazvo nekuyedza. Zviripachena, ivo vari kuronga kuitisa zvimwe zviedzo zvichitevera izvi zvabuda.
Inogona here iyo inoshamisa carnivore kuva iyo Kraken - inoshamisa gungwa chikara chehukuru hukuru uye cephalopod-kunge chitarisiko muScandinavia ngano? Kana chimwewo chinhu chatisina kana kumbofunga nezvacho?
Kana iwe uchida kuziva nezveKraken uye zvisinganzwisisike zvisikwa zvakadzika zvegungwa wobva waverenga chinyorwa ichi nezve isinganzwisisike USS Stein monster. Mushure meizvozvo, verenga nezve izvi Zvisikwa zvinoshamisa paPanyika. Mukupedzisira, ziva nezve izvi 14 mazwi asinganzwisisike anoramba asina kutsanangurwa kudhara.
