muviri wake ane streamlined chimiro torpedopodobnuyu. Musoro ndiwo mupfupi hama kuti mutumbi wose. Shaya chikara chiri pasi. Shaya pahupamhi uye unwieldy. Rezasi Dziine sikweya kungopotsera meno, uye okumusoro - isingawanzowanikwi unopinza. Kukwirira uye mumwe anoita haapfuuri 7 mm. Caudal zenze heterocercal kutaipa shure - woita chimiro uye diki kukura.

selachians muviri ane ruvara kubva shava kusvika rutema, dzimwe nguva ane greenish tinge. Zvayaiva kumativi mutumbi rima pepuru mavara. Shark meso diki, mutema, pasina rwokudzivirira membrane.

STRUCTURAL zvinhu

In Zimbabwe Shark guru nuna chiropa, riri kupfuura 20% mukanyiwa muviri. muviri Izvi zvinoshanda sezvi- ichiyangarara.

rehove munyama nomuti zvakasimba amoniya uye trimethylamine oxide. yeimwe kwakadaro tunodzivisa nechando ropa, mapuroteni uye kuramba operability chakaipa chokubuda mamiriro zvipenyu pezvakaitwa kuchamhembe. Zvose zvinhu zviri muchetura, saka rehove ane zvinosemesa kuravira kwete chete, asiwo kungaita kuti muchetura - pasi pokudzora gastric muto trimetilaminoksid ichichinja trimethylamine, iro rinoita kuti chidhakwa mugumisiro. The dundira haisi shark, saka tsvina hwokurara kubudikidza ganda.

Mhuka idzi dzinoratidzwa ne zvinoorora kukura uye kunonoka. Speed rwokufamba kwayo zvinoshamisa diki - kupfuura mumwe kiromita paawa. Izvi imhaka yokuti, kugara mumvura inotonhora, vakawanda simba nemisha anomanikidzwa kupedza pamusoro muchidziisa muviri wako. Zimbabwe Shark - akapona pakati vamiririri mhuka nyika. Sezvakataurwa, ya upenyu hwayo kusvika makore 500.

Age polar rehove akakwanisa kumisa mapuroteni pakati ziso raMwari izvo. Inokura hwose, uye mapuroteni ayo anobudiswa panguva padariro embryo kukura. Radiocarbon kuongorora akatibvumira kuziva nezvokuvapo zviri kabhoni-14 isotope, kwakaitika pashure sefungu nemiedzo mabhomba mabhomba. Mumwe aiva 392 makore nyanzvi aidzidza Sharks. Kufungisisa yokukanganisa radiocarbon nzira yokudzidza akawana kuti polar rehove anogona kurarama kwemakore 500. hurefu kwakadaro rinotsanagurwa ndechokuti zvose pezvakaitwa upenyu mumvura inotonhora zvikuru kunonoka kupfuura thermophilic vamiririri mhuri iyi.
