Lesitshalo oshaka, amagama, izici futhi amaqiniso athakazelisayo

Ngenxa Hollywood, yilowo nalowo kithi ushaka yena njengoba nombulali onesihluku yobukhulu omkhulu, imini nobusuku ukuchukuluza ababhukudi abangaqaphile. Ngeke siphikisane izizathu lo mbono yilezi: ushaka namanje uma ibona izilwane eziyingozi nokuzingela izilwane zasendle ukuziphatha kwabo okungokwemvelo. Nokho, kukhona zoshaka ezingu, ngokuphelele hhayi eyingozi kwezidalwa ezinkudlwana, okungase ngokuphepha kuchasiselwe umuntu. Futhi kukhona izinhlanzi ezidla inyama, ngezindlela eziningi (noma kunjalo, ekudleni) zifana whale.

Futhi oshaka ku ukumelwa evamile akuyona ocacile ngakho. Kukhona zoshaka ezingu ukuthi afinyelele 11-15 amamitha ngobude (zezinhlobo ikakhulukazi ezinkulu whale shark). Futhi kukhona 15-isentimitha umntwana, kuyingozi kuphela nezinhlanzi ezincane futhi ngenkuthalo skedaddle kusukela iningi elikhulu esiphikisayo eziphilayo.

Ushaka ngokuvamile

Kungakhathaliseki ukuthi bale superorder ezahlukene nomunye, bonke oshaka izici ezivamile isakhiwo, izitho zomzimba nokuziphatha:

1. Uhlaka lwamathambo lezi izidalwa ayakhekanga ithambo izicubu bese uqwanga, okwenza oshaka lula, emincanyana futhi beshesha.
2. Bonke abanalo esinyeni sibhukuda, ngaphandle okuyinto iningi enye inhlanzi ayikho.
3. Abenzi lutho embozwe izikali isikhumba, futhi Friend kakhulu, efakwe amancane namazinyo abukhali. Abantu abaningi futhi izilwane zasemanzini dlulisa wayohlangabezana oshaka alikho kwamazinyo abo, futhi kusukela contact ngephutha lapho sihlala esikhunjeni.
4. Phakathi kwalezi izilwane ezidla ezinye babe zoshaka ezingu ukuthi musa eziyizimbangela, futhi viviparous. Nokho, ngisho naphakathi kwalabo ababengene waqhubeka bendabuko xaxa zasemanzini ukuphila esiphelweni endleleni, esigabeni esimaphakathi yentuthuko akuyona caviar, kodwa kunalokho uhlobo amaqanda: zimbalwa kakhulu (1 kuya ku-3), futhi ivikelwe kanzima kakhulu igobolondo, igobolondo . Futhi kusukela kulesi sitolo aliveli gazinga, nezinyane kwakhiwa. Ngakho ikakhulukazi ngoshaka iye waqamba a elithi "ovoviviparity" entsha.
5. Ngo kwezinhlobo eziningi namazinyo izinhlanzi sikhule izingqimba eziningana (3 kuya 5), iyiphi i-akhawunti kuze kube ayizinkulungwane. 3 Canines futhi olusha njalo. Caries lezi zidalwa asesabi!

Endaweni ehlukile, kukhona umbuzo: kanjani izinhlobo eziningi ushaka aziwa isayensi. Iqiniso liwukuthi abaningi kubo kwakukhona nedlanzana kuphela noma abameleli ababili. Futhi abanye baye okwethulwa nesisodwa eqoshiwe ososayensi. Ngomqondo onabile, emhlabeni kukhona 150 zama-oshaka - ungomunye waleyo ukuhlangabezana abacwaningi zasolwandle emazweni amaningi, futhi izikhathi ezingaphezu kwesisodwa. Banikezwe ezisengozini (ikakhulukazi ngenxa abazingela ocean nomzingeli) zilwane, inombolo yabo kungenziwa kalula lande laba ngu-268. Abanye abacwaningi bakholelwa ukuthi lesi sibalo kungaba bayovuswa ukuze 450, kodwa lonke zoshaka eyaziwa kuphela kusukela ubufakazi ngengozi zingashayisani nabo izazi zesayensi yezinto eziphilayo.

ushaka babhekwa

Lokhu "isizwe" astonishes ososayensi dissimilarity zabo, futhi ngezinye izikhathi ukuphikisana (ngaphandle imenyu), okuyinto abonise uhlobo oluthile oshaka. Ngakho, kufanele kube torpedopodobnuyu ukuma izinhlanzi umzimba - lokhu kwenza kube lula ukuze azingele imvelo yasemanzini. Kodwa kukhona ezinye izinhlobo esachazwa ezizingelayo, efana le misebe bese flatfish: bafuna inyamazane eduze kwangaphansi. Lamanye ahamba nomlomo flat futhi ebanzi kakhulu. Kanti ezinye zingafakwa ngizibonge ekhaleni abukhali. Kodwa ngenkathi izici eziyinhloko isici kufanele zonke izinhlobo oshaka.

Esinye isici: kokuba amazinyo abukhali ngokuvamile zikhule emuva ngokuqhubekayo, inhlanzi nomzingeli uzisebenzisela kuphela kulokhu kuhlasela. Kwanele yimpango yabo futhi likhiphe, kodwa musa ukuhlafuna. Yingakho zonke ukugcwaliswa wakhe temlomo na siqukethe kuphela of Amazinyo - namazinyo posterior ushaka khona.

Lesitshalo oshaka: amagama iyingozi kakhulu kubantu

Ubuningi lezi ezidla ezinye uhlu amagama kunzima kakhulu. Olunye uhlobo, lo abakhuluma isiRashiya ontanga amagama kungaqali, kukhona kuphela amagama Latin zohlobo ngalunye oluphilayo zakwazi oshaka. Nokho, izingane kanye nabantu abadala, kubalulekile ukwazi mayelana eziyingozi kakhulu babo, uma kufanele eduze nolwandle, lapho izidalwa ezinjalo zitholakala.

Umhlangano omkhulu kunayo yonke, abesabekayo noshaka abadumile - omhlophe omkhulu. It ebangela ingxenye yabo bonke lokufa kwabantu ngenxa yokuhlaselwa oshaka, futhi ngamakota amathathu nakho konke ukuhlaselwa kwalezi zilwane. Into kuphela ukuthi uqinise: lokhu nomzingeli ngaphezulu ukunambitha sea izingonyama, ingcuba, Imikhomo nezimvu zamanzi. Uma ungenalo avuse okwaso uzolimala emanzini kuze kube segazini - aphinde abhukude abuyele by.

indawo sesibili tiger shark. Isidlaliso ethola sibonga imivimbo mpo emzimbeni. Isizathu sesibili Bekungubani umlingisi ezimbi - Shark nolaka futhi omnivorous. Nalapha futhi, ngaphandle sicasulwa jaha indoda ayivelanga, nakuba bengase ujabulele, ngaphandle nje umkhuba eyolanda konke kwenzeka endleleni.

Bull ushaka oceanographers waqaphela njengoba enolaka kakhulu wonke amalungu superorder. Okubi nakakhulu, i-ke ungaya emlonyeni nemifula emikhulu. Liyasibhozomela ku yini enyakazayo, kungaba ukuhlasela e angajulile. Ngakho uma resort ukuxwayisa ukuthi abameleli amanzi kubonakala kwalesi silwane oshaka, kungaba ukuhlakanipha ukuya ebhishi. Futhi ungahambi kuze kuvunyelwe.

Ukwesabeka kwezilwandle: cigar ushaka

Kusukela umbono ngenxa yelukuluku, interesting okuningi ukucabangela zilwane kancane aziwayo oshaka. Kukhona izinhlanzi kwalesi isizwe esinhliziyo obuphelele - cm 42 kuphela, futhi ubukeka - sethusa futhi iwubuphukuphuku. Omude kunayo yonke owake cigar ushaka namazinyo ukwenza kube into efana bulldog zasolwandle. Kodwa futhi ngokwalo kuyinto umhlaseli esabekayo: kungaba ukubulala ocean abakhileyo kahlanu kunangendlela ngokwabo.

Izazi zezinto eziphilayo shayela ekudalweni ezinjalo ectoparasites. Yena ukuluma ku isisulu buthule yena udle away isinqamu esiphawulekayo esithi "umthuthi" yenyama. abantu elikhulu avunyelwe ukuma emuva kwalokhu kuhlaselwa, kodwa labo izinhlanzi / izilwane ifaniswe noma kancane idlule izilinganiso umqali, afe.

Ngokokuqala ngqá, "ugwayi" wabanjwa ngo-1964 eGulf of Mexico, futhi kusukela ngaleso sikhathi kuphela nedlanzana sezihlobo zakhe ithole ezandleni ichthyologists. Ngakho labo kakade ukubonwa abanye oshaka, lokhu akuyona neze ajwayelekile.

Ushaka Angel: ukugqiba ubuhlakani

Lolu hlobo shaka ezinye ukulungisiswa ubizwe ngakho. Futhi hhayi ngenxa yemvelo lithambe: izinhlanzi nje ingeyona ingozi ngokwanele. Hlangana diver yakhe kuzoba ukuqinisekisa ukuthi wayethole endleleni eyakhelwe. Hambisa "izingelosi" eduze ekuzingeleni kusukela abaqamekeli, bese ulinda kungaba ukuchitha amahora noma ngisho izinsuku, ngesikhathi esifanayo ulondoloze isimo obucwathile ephelele.

Ngenhlanhla, abantu "izingelosi" abanandaba futhi kungukuthi ezingelwa. Kodwa uma umzingeli yokuquba isinyathelo (ngisho nangokwengeziwe ukuzama ukubamba), ke uzophendula umbani kuhlasela okusheshayo futhi ononya. Amanxeba akuzona ebulalayo, kodwa igazi, kubuhlungu futhi ezidinga ukuthi kungenelelwe ukuhlinzwa.

Abahlukile lemon ushaka

omele Lesi sizwe okuzingela iyingqayizivele ngempela. Okokuqala, ngeke ukulimaza bona ukubhukuda isikhathi eside ukuphila ngamanzi agobhozayo. Okwesibili, le ushaka uyakwazi isikhathi eside ukuba alale phansi - futhi lukhetha yokuzingela ekujuleni encane kuze kufinyelele imitha elilodwa. Okwesithathu, sibonga umbala okuhlanganisiwe kahle ezungezile. Umuntu akadli, kodwa inja yakhe ayithandayo - ngaphandle nobunzima.

Ngokungafani ingelosi ushaka, ukhetha ukugwema ukuthintana, kodwa ukuhlaselwa iyaphendula ngobudlova. Nokho, baye kancane kakhulu, zitholakala ngokuyinhloko amanzi aseNingizimu Melika, ngakho ukubona amathuba wakhe omncane.
