imihlobo porpoises

Ngokuthe gabalala, baye bohlulwa babe ngamaqela amathathu: finless, emhlophe ezinamaphiko nabaqhelekileyo. Abameli wokugqibela iintsapho iquka iintlobo ezine. Leyo ezingama amagqabi ezintandathu. Zahluke kakhulu enye kwenye, zombini imbonakalo kunye yokuhlala. Ezinye iintlobo bakhetha ukuhlala iipasile, lo gama abanye uhlala wedwa. Phakathi kwazo aqhelekile nezilwanyana zaselwandle, kwaye yayisecicini yokutshabalala. Noko ke, zofuzo lonke usapho olunye.

pig finless

Kwathiwa igama ngenxa nokungabikho ephikweni amaphiko. Kucingwa le ngxaki eku xhulumaneni incinane elizweni (amalungu aseleyo entsapho kukho enye). imilinganiso yalo, musa ukudlula 1.2 yeemitha. intloko Small ngaphandle ngomlomo kunye ibunzi ngeenxa - isici esasenza ezi zilwanyana. Umzimba egudileyo, izimvi ezimnyama (ngamanye amaxesha - phantse abamnyama) umbala, ngamanye amaxesha kunye ithinti kancinane oluhlaza. Hlala porpoises ezinjalo ekukhethwa Indian kunye Oceans Pacific ukusuka eKapa ukuya kunxweme Japan. Gcina izilwanyana ungakwazi noba zibangele okanye ngamaqela amancinane.

Ihagu (elwandle) vulgaris

Yahlulahlulwe yaba zenyathi ezintathu ezihlala phantse kuyo yonke indawo, kuqalwa iNorth Atlantic Ocean egqibela Pacific emdeni East Far. lwentlanzi Common - ummeli wendlela izilwanyana iBlack kunye Azov Seas. Iinkunzi zincinane kwe iimazi yezi zilwanyana, ubungakanani yabo ngaphezulu kweemitha enye enesiqingatha ubude. Zidla zigcinwe ngamaqela, ukutya intlanzi. osemqoka zazo eziphambili kukuba lo gama uphefumla ukuba ungatsibeli ephuma emanzini. Ngeso lenyama idla abamnyama okanye emnyama ingwevu, inxalenye esezantsi kumzimba ongentla lighter.

Black Sea kwizibuko lwentlanzi, izibuko lwentlanzi okanye ebizwa nge parameter zabo zahlukile zemfuza ukusuka kwiBaltic kunye ohlobo Pacific. Kodwa kuyacaca ukuba ziyafana kakhulu. iihagu zesiqhelo kakhulu ngaye umntu, kuba kaninzi kubanjwa esekuthinjweni dolphinariums, okugcinwa kunye namaziko ophando.

Nangona inani elikhulu labantu, ngobanjiso mveliso yezi zilwanyana akuvumelekanga kumazwe amaninzi (ngaphandle eJapan, apho basetyenziswa ukutya).

ntlanzi

Inani le ezincancisayo catastrophically ephantsi. Ngokutsho izazinzulu, endle abanayo abantu hayi ngaphezulu kwe-300. Ngenxa yesi sizathu, nokubanjiswa nasezilwanyaneni esalelweyo ngqo, kodwa le meko akuncedi, kuba kuchaphazela inani bume kakuhle kwaye kukho inani elikhulu ookrebe kwindawo yokuhlala. Zihlala kuphela i-Gulf of California, nto leyo eba ubunzima evela iminatha yokuloba.

Ukuphila ekuthinjweni

Ekubeni ekubambiseni iintlobo ezininzi iintlanzi akuvumelekanga phantsi kweemeko ngumntu abanjelwe alufane. Ngokusisiseko, sithetha akwariyam, amaziko ophando, eku xhulumaneni kunye nakumaqonga ulwandle. Nangona ukuhlakanipha izilwanyana ingabizwa buthathaka, baqeqeshelwe ebunzimeni. Ngenxa yesi sizathu, kule izimvo zisetyenziswa kunqabile.
