Mhando Sharks, mazita, maitiro uye zvinonakidza zvinhu

Nemhaka Hollywood, mumwe nomumwe wedu ari shark pachake somunhu utsinye muurayi rakakura kukura, masikati nousiku chiri vasina kungwarira vanoshambira. Hatidi nharo zvikonzero pfungwa iyi ndiwo: rehove ichiri zvikara uye yokuvhimwa mhuka iri yavo yepanyama maitiro. Zvisinei, pane mhando Sharks, zvachose kwete ngozi zvisikwa hombe, izvo zvinogona zvakanaka vaiti munhu. Uye kune hove dzinodya dzimwe dzinosiya, izvo muzvinhu zvakawanda (chero zvazvingava, zviri zvokudya) vakaita whale.

Uye ukuru Sharks iri senguva mufananidzo haisi kudaro inonzwisisika. Kune mhando Sharks kuti tisvike 11-15 metres urefu (specimens kunyanya huru Whale shaki). Uye kune 15-sendimita mwana, ngozi chete nehove diki uye nesimba kuti skedaddle kubva vakawanda hombe yemabhuku-zvinenge.

Shark vakawanda

Pasinei zvakasiyana dzinomiririra superorder ichi mumwe, Sharks zvose dzinowanzotaurwa zviri marongerwo, physiology uye maitiro:

1. The marangwanda zvisikwa izvi haina kuumbwa pfupa rinenge uye shwashwa, zvichiita Sharks kupenya, nimble uye zvatinogadzira hazvigoni kunyatsotevedzera zvinoita.
2. Vose havana dzinoshambira dundira, pasina muya dzimwe hove hahugoni kuvapo.
3. Havana akafukidzwa chikero uye ganda, uye zvakasimba kwazvo, wakabatanidzwa pamwe unopinza meno tuduku. vanhu vazhinji uye mhuka zvomumvura vanourayiwa mu kunosangana Sharks hakusi nemazino avo, uye kubva netsaona kuonana ganda.
4. Pakati pazvikara izvi vane mhando Sharks kuti murege kuita kuti pave, uye vari viviparous. Zvisinei, kunyange pakati pevaya vakakwira pamusoro zvikuru chinyakare kuti hwemvura upenyu kupararira nzira, ane zvenguva padanho kukura haisi caviar, asi kutoti mhando mazai: vashoma kwazvo (1 kusvika 3), uye vari kudzivirirwa zvakasimba chaizvo goko, deko . Uye kubva ichi chitoro sokuti haana furaya, uye kuumbwa mhuru. Saka kunyanya Sharks kwave sezvaari idzva rokuti "ovoviviparity".
5. In mhando dzakawanda meno hove vachikura dzakawanda akaturikidzana (kubvira 3 kusvika 5), izvo zvinokonzera anosvika zviuru. 3 Canines uye yoku- nguva dzose. Caries zvisikwa izvi hazvisi kutya!

Oga, pane mubvunzo: sei mhando dzakawanda rehove nesayenzi. Chokwadi ndechokuti vazhinji vavo kwaingova gumi kana vamiririri vaviri. Uye vamwe nenzira chiitiko chimwe chakanyorwa nemasayendisiti. In musimboti, munyika mune 150 mhando Sharks - mumwe avo kuti asangane Vatsvakurudzi zvomumvura munyika dzakawanda, uye kupfuura kamwe. Tichifunga panjodzi (kunonyanya kukonzerwa kuvhima penyanza chikara) marudzi, nhamba yavo inogona nyore chakawedzera kusvika 268. Vamwe vaongorori vanodavira kuti nhamba anogona achamutswa kuti 450, asi vamwe rehove kwemarudzi anozivikanwa chete kubva uchapupu netsaona colliding navo zvipenyu.

shaki oddities

Izvi "rudzi" astonishes masayendisiti dissimilarity dzavo, uye dzimwe nguva daka (kunze Muterere), izvo kuratidza mumwe mhando Sharks. Saka, tinofanira kuva torpedopodobnuyu muviri hove chimiro - ichi kunoita kuti zvive nyore kunovhima ari hwemvura zvakatipoteredza. Asi pane dzimwe mhando akarondedzerwa pazvikara, kufanana nemwaranzi uye flatfish: vanotsvaka chakaurawa pedyo pasi. Vamwe vari sandara uye yakafara chaizvo tomu. Vanongogona vamwe vanonyadziswa jeko mhino. Asi apo huru unhu zvinhu vane mhando dzose Sharks.

Chimwe chinhu: kuva unopinza meno anomera shure dzose, hove chikara anodzishandisa chete kurwisa. Zvakwana zvavo uye kuibvarura, asi regai kutsenga. Ndokusaka zvose nomumukanwa zvekupfakira yake uye rinoumbwa bedzi pamusoro fangs - posterior meno shark ikoko.

Mhando Sharks: mazita zvikuru ngozi vanhu

Zvakawanda pazvikara izvi kunyora mazita zvakaoma chaizvo. Mune dzimwe mhando, kuti mutauro wokuRussia vezera mazita uye haaiti, pane mazita Latin chete neimwe mhando Sharks. Nokuti vana nevakuru Zvisinei, zvinokosha kuziva pamusoro kupfuura ngozi vavo, kana iwe kunge pedo mugungwa, apo zvisikwa zvakadai anowanika.

The pakukura, vanotyisa uye yakakurumbira rehove - chena kukuru. Nezvokuvandudzika hafu kufa zvose kwevanhu kubva rehove kurwiswa, uye-makota matatu kurwiswa zvose mhuka idzi. Chinhu bedzi nokunyaradza: chikara ichi zvakawanda kuravidza gungwa shumba, zvakaora, hove huru uye nemicherechedzo. Kana iwe musanetsa uye handaizorwadziswa nemvura neropa - swims napo.

nzvimbo yechipiri nokuti ingwe shark. Nickname iye akagamuchira kuonga kutwasuka kurohwa pamusoro muviri. Chikonzero chechipiri chaiva chimiro chakaipa - Shark nehasha uye omnivorous. Zvakare, pasina kudenhwa dzingirira murume haasi, kunyange zvazvo vanganzwa vanonakidzwa, chete kubva tsika tonotora zvose zvinoitika munzira.

Bull rehove oceanographers vakaziva sendarama hasha nhengo dzose superorder. Kupfuura zvose, kunogona kupinda mumuromo nzizi huru. Rinobvuta pachinhu chinoita kuti, anogona anorwisa muna shallows. Saka kana dzisina ukanyevera mvura wakaona kuti vamiririri marudzi iyi Sharks, kwaizova kuchenjera kuenda kumhenderekedzo. Uye musingaendi kusvikira kubvumirwa.

Kutya mumakungwa: sigaa shaki

Kubva pfungwa nemaonero kuziva, zvikuru kukurukura zvishoma kuvazivisa rudzi Sharks. Pane nehove rudzi urwu, ane urefu - 42 chete cm uye anotarisa - unotyisa uye musoro. The chakarebesa mazino fodya rehove kuiita akafanana zvomumvura bulldog. Asi pachazvo anotyisa chikara: unogona kuuraya yomugungwa vagari kashanu kupfuura pachavo.

Vanodzidza nezvezvinhu zvipenyu vanodana kusikwa kwakadaro ectoparasites. Iye kuruma kupinda munhu chinyararire mumwoyo uye kudya kure chinokosha bimvu kuti "keriya" nyama. vanhu Large akabvumira kumira pashure kwacho, asi hove avo / mhuka dziri akafanana kana zvishoma kusapfuudza kukura atadza, vanofa.

Kokutanga, "fodya" akanga abatwa 1964 mu muGulf of Mexico, uye kubvira ipapo chete gumi hama dzake akamuka mumaoko ichthyologists. Saka vaya atoona zvimwe Sharks, izvi zvakaoma dzinodanana.

Shark Angel: masking shasha

Miti iyi Sharks vane zvimwe kururamiswa kunzi saizvozvo. Uye kwete nemhaka rakapfava hunhu: hove chete anotarira mhosva zvakakwana. Kunomuchingamidza dhaivha zvichava chaizvoizvo nechokwadi chokuti awana nenzira imwe murwere. Kutama "ngirozi" pedyo kundovhima kubva vakavavandira uye kumirira kunogona kupedza maawa kana mazuva, apo kuramba Kuchakati zii zvakakwana.

Sezvineiwo, vanhu "ngirozi" hava- uye haana Vakaronda. Asi kana muvhimi inovandira danho (uye kunyange zvakawanda kuedza kubata), zvichakanganisa sei mheni kutsanya uye utsinye kurwisa. Maronda havasi zvinouraya, asi ropa, inorwadza uye zvinoda kuvhiya kupindira.

Unique ndimu shaki

Izvi mumiririri dzinodya dzimwe dzinosiya rudzi zvechokwadi rakasiyana nerevamwe. Chekutanga, izvozvo hazvigoni kuti pachavo uye kushambira kwenguva refu kurarama nemvura yakachena. Chechipiri, rehove ichi anokwanisa kwenguva refu ndirare pasi - uye anoda kunovhima maduku pakadzika kusvikira mumwe mita. Chechitatu, akavonga noruvara nayo merges nechiverengo akapoteredza nzvimbo. Munhu haadyi, asi imbwa yake anodiwa - pasina dambudziko.

Kusiyana ngirozi rehove, iye anoda kuti usagunzva, asi kurwisa anopindura rinopikisa. Zvisinei, havana zvishomanana, zvinowanika kunyanya mumvura South America, saka kuona mukana kake.
