Zizindikiro zakunja kwa whitetip shark imvi.
Shark whitetip shark ili ndi thupi lopapatiza, losasunthika lokhala ndi mphuno yaitali, yozungulira. Mapiko a caudal sawoneka bwino, okhala ndi lobe yayikulu kumtunda. Kuphatikiza apo, pali zipsepse ziwiri zakuthambo. Yoyamba ndi yayikulu komanso yosongoka, ndipo imayandikira pafupi ndi thupi lomwelo monga zipsepse za pectoral. Chomaliza chachiwiri kumbuyo ndikocheperako ndipo chimayendera limodzi ndi kumapeto kwa anal. Pali mtunda pakati pazipsepse zakuthambo. Zipsepse za pectoral ndizitali, zooneka ngati kachigawo kakang'ono komanso kansonga kakuthwa poyerekeza ndi zipsepse za mitundu ina ya shark imvi.
Shark whitetip shark ili ndi mano opha mano kunsagwada yakumunsi komanso kumtunda. Mtundu wonse wa thupi ndi wakuda kapena wotuwa pamwamba; ma scuffuff oyera amawoneka pansipa. Zipsepse zonse zili ndi nsonga zoyera m'mbali mwake; ndichizindikiro chomwe chimasiyanitsa nsombazi ndi abale awo apafupi: shark reef shark ndi whitetip reef shark.
Shark whitetip shark amakula mpaka 3 mita kutalika (pafupifupi 2-2.5 mita) ndipo akazi nthawi zambiri amakhala akulu kuposa amuna. Kulemera kwakukulu kwa whitetip gray shark ndi 162.2 kg. Pali mitundu iwiri isanu ya ma gill. Mano adakonzedwa m'mizere 12-14 mbali zonse za nsagwada zonse. Pa nsagwada zakumtunda, zimakhala zozungulira zazing'ono zazing'ono zazing'ono m'munsi mwake ndipo zimapindika kumapeto. Mano otsika amasiyanitsidwa ndi magawo ang'onoang'ono.
Kuswana kwa imvi whitetip shark.
Grey Whitetip Shark amakwatirana m'miyezi yotentha. Amuna amakhala ndi ziwalo zoberekera zofananira, zotchedwa nkhupakupa zomwe zili kumapeto kwa zipsepse zawo. Amuna amaluma ndikukweza michira ya akazi nthawi yokwatirana kuti atulutse umuna mu chovala chachikazi cha umuna wamkati. Shark whitetip shark ndi viviparous.
Mazira amakula mthupi la mayi, ndikudyetsa kudzera mu placenta kwa chaka chimodzi. Nsombazi zimabadwa kuyambira 1 mpaka 11 ndipo zimafanana ndi nsomba zazing'ono zazing'ono, kutalika kwake ndi masentimita 63-68. Amakhala m'malo osaya amiyala ndikusunthira m'madzi akuya akamakula. Amuna achimuna amatha kubereka kutalika kwa mita 1.6-1.9, akazi amakula mpaka mita 1.6-1.9. Kusamalira ana amtundu uwu sikuwonedwa. Palibe zambiri zakutsogolo kwa imvi whitetip shark machilengedwe. Komabe, mitundu yofanana kwambiri imatha kukhala zaka 25.
Khalidwe la whitetip shark.
Shark whitetip shark nthawi zambiri amakhala nsomba yokhayokha, ndipo magawidwe ake amagawika, osalumikizana ndi anthu anzawo.
Ngakhale amatha kukhala achiwawa akawopsezedwa, palibe umboni kuti amakhala kudera linalake.
Nsomba za Whitetip imvi zimawonetsa nkhanza, ndikusokoneza nyama zazikulu. Amasuntha zipsepse zawo zam'mimba ndi mchira, amapindika mthupi mwamphamvu osasunthika, "amanjenjemera" ndi thupi lawo lonse ndikutsegula pakamwa, kenako yesani kusambira kutali ndi mdaniyo. Ngati chiwopsezocho chipitilira, nsombazi, monga lamulo, musayembekezere kuukira, koma nthawi yomweyo yesetsani kuthawa. Ngakhale samakhala kudera, whitetip shark amaukira anthu amtundu wawo, ndichifukwa chake nthawi zambiri amakhala ndi zipsera pankhondo mthupi mwawo.
Kwa anthu, mtundu uwu wa nsombazi umaonedwa ngati wowopsa, ngakhale kuti kuchuluka kwa omwe alumidwa sikokwanira kwambiri poyerekeza ndi mitundu ina yayikulu ya shaki.
Maso a whitetip imvi shark amasinthidwa kuti azitha kuwona m'madzi amatope, izi zimawathandiza kuti awone maulendo 10 kuposa masomphenya a anthu. Mothandizidwa ndi mizere yotsatira ndi maselo am'mimba, nsombazi zimatha kugwedezeka m'madzi ndikuwona kusintha kwamagetsi komwe kumawachenjeza za omwe angawakhudze kapena adani awo. Amakhalanso ndi makutu omveka bwino ndipo kununkhira kwamphamvu kumawalola kuti azindikire magazi ochepa m'madzi ambiri.
Kudya imvi whitetip shark

Amakhala aukali kwambiri akamadyetsa kuposa mitundu ina yambiri ya nsombazi komanso amathamangira mozungulira chakudya akagwidwa.
Udindo wa imvi whitetip shark.
Shark whitetip shark amachita ngati nyama zolusa m'chilengedwe ndipo nthawi zambiri amalamulira mitundu ya shark monga ma Galapagos ndi ma blacktip shark. Nsomba zina zazikulu zimatha kusaka ana. Ma Ectoparasitic crustaceans amapezeka pakhungu la nsombazi. Chifukwa chake, amatsatiridwa ndi nsomba zoyendetsa ndege ndi utawaleza, zomwe zimasambira pafupi kwambiri ndikutola tiziromboti ta khungu.
Kutanthauza kwa munthu.
Nsomba za Whitetip imvi zimawedza. Nyama, mano, ndi nsagwada zawo zimagulitsidwa, pomwe zipsepse zawo, khungu lawo, ndi khungwa zimatumizidwa kunja kuti apange mankhwala ndi zikumbutso. Nyama ya Shark imagwiritsidwa ntchito ngati chakudya, ndipo ziwalo za thupi ndizopangira zinthu zofunika popanga zinthu zosiyanasiyana zapakhomo.
Ngakhale sipanakhalepo kuwukiridwa kwa shark whitetip shark kwa anthu padziko lonse lapansi, nsombazi zitha kukhala pachiwopsezo kwa anthu omwe akuyenda pafupi ndi nsomba.
