Ihlengethwa Black Sea. izinhlobo amahlengethwa

Lezi ezincelisayo zasolwandle ezincane kunazo zonke oda Cetacea. Manje ososayensi has abangaba ngamashumi ayisihlanu zama-amahlengethwa.

incazelo

Lezi abakhileyo kolwandle basonta subfamily ezincelisayo, izilwane zasemanzini ezincelisayo lamabutho, ozala amahlengethwa. Yabo obuphelele umzimba zokhahlamba kusuka 1.2 kuya kumamitha angu-3, kwezinye zezinto eziphilayo, ifinyelela 10 m. Cishe zonke izinhlobo amahlengethwa abe fin ngemuva. Futhi side in the "uqhwaku" ubuso inani elikhulu namazinyo (70).

Dolphins olwandle siholwa amaza omsindo. Izilwane ukuzwa mncane kakhulu - kunyakaza umsindo ayatholakala kusukela amashumi amaningana Hz 200 kHz.

Amahlengethwa awazona endowed ngezwi eyinkimbinkimbi kanye alamu mkhosi umsindo, amaza omsindo isitho ise ikhala (kuphela). Lihlobene nokubhekana ubuso air bag eziyisithupha kwemisipha uhlelo. amasignali Frequency Babechichima - mayelana 170 kHz.

Kumelwe ishiwo emaphakathi kakhulu nesimiso sezinzwa kwalezi zilwane - ubuchopho ezinkulu, eyindilinga, ama- yayo cerebral babe meanders eminingi (namagxolo ihlengethwa ubuchopho has ezinzwa 30 billion). ubungako bobuchopho olunjalo olwenza amahlengethwa ukucubungula semali Imininingwane engenayo abangakwenza, efana zopholi, ukopisha namazwi ashiwo umuntu.

Ukuma hydrodynamic yomzimba, anti izakhiwo yezinxushunxushu kanye nesakhiwo kwesikhumba, hydroelasticity umphumela (obulungisekayo) e amaphiko, ikhono eliyingqayizivele kufike ekujuleni okungaphezu kwalokho omkhulu nezici nezinye eziningi amahlengethwa amashumi eminyaka abasekeli anentshisekelo Bionics.

Lezi zilwane cute agcinwa dolphinariums eziningi oceanariums ngoba baqeqeshiwe kalula futhi trainable. Namuhla, izinhlobo eziningi amahlengethwa "ukusebenza" e esekisini. Manje sicabanga ukuthi kungenzeka ukufuywa kwamakamela uhlobo oluthile lezi zilwane.

Ngeshwa, emazweni amaningi ayisihloko zokudoba (isib lagenorhynchus eJapane stenella). Enkulumweni wethu wokudoba kwalezi zilwane wavinjelwa 1966.

Isihloko ingxoxo yethu namuhla ihlengethwa Black Sea. Sizoqala ukuba izinhlobo ezintathu eziyinhloko ngezinto eziphila olwandle.

Bottlenose, ihlengethwa noma enkulu

Lona zinhlobo ezivamile futhi wafunda kakhulu, okuyinto evame atholakala okugcinwa Black Sea. ihlengethwa bottlenose - dolphin, okuyinto kulula ukubekezelela abanye ebugqileni.

Lezi ezincelisayo zasolwandle akhule 3 metres uphinde uthele kancane nzuzo isisindo amakhilogremu angu-300. Ngokuvamile ihlengethwa Black Sea iyasebenza ngesikhathi sasemini, uphumule ngesikhathi sokushona kwelanga.

Bottlenose ihlengethwa ukuzingelwa izinhlanzi, kodwa ungadikibali, futhi kusukela nezimfanzi, i-squid, cephalopods. Hunting Isikole inhlanzi, amahlengethwa eqoqelwe ndawonye. Ufuna imisebe ne-shellfish, bona wehlele ezweni 300 m ukujula.

ihlengethwa bottlenose - dolphin Iyasithwala imihla ngemihla; kudle engaphezu kwengu-15 amakhilogramu zezinhlanzi. Izitha abe kancane - kuba imikhomo emikhulu futhi oshaka. umonakalo Obalulekile kumuntu okubangela sabantu. Amanetha okudoba izilwane ngokuvamile ukugaxela futhi bafe. Echo Sounders izitsha zasolwandle naye ongumsolwa kuleli cala kokufa amahlengethwa. Iqiniso lokuthi ziqondiswe Locator okuthiwa.

Underwater ihlengethwa imisindo asakaze ngesivinini, ziyabonakala kusuka lezinto bese ubuye. Ngakho isilwane ithola ulwazi mayelana izithakazelo into yayo. Uma izizwa "izihambi" umsindo wave sonar, ungakwazi ulahleke emkhathini. Bavame vela ku ushayisa intaba yesihlabathi. Kunezibonelo eziningi, izimo ezinjalo ngokuvamile senziwe imizila lwemikhumbi.

ihlengethwa imisindo

Ichthyologists, ukutadisha bottlenose amahlengethwa, bathole ukuthi banayo anhlobonhlobo imisindo, ezisetshenziswa ukuxhumana ngaphakathi umhlambi. Ngemva kokuhlaziya amarekhodi "izingxoxo", abacwaningi baphetha ngokuthi "isichazamazwi" bottlenose 17 imisindo. Ekufuneni yimpango yabo, benza "namagxolo" lapho sidle ukudla - "Meow" nalapho uya ukwesabisa abaphikisi, benza imisindo efana ukotini. Ezinhlanu kuzo baqonde oLwandle Olumnyama amahlengethwa beaked nomshayeli whale. Labo abasele abanga-12 umsindo ngempela esiyingqayizivele. Abaqeqeshi bathi inhlanganisela ezahlukene lezi zimpawu ivumela izilwane ukuxhumana nomuntu.

kabusha bottlenose amahlengethwa

Entwasahlobo nasehlobo amahlengethwa yokukhwelana kuyaqala. Ngalesi sikhathi izilwane ebe eziphatha ngendlela eyehlukile, njengenjwayelo - umzimba wonke bend, thatha postures ekhethekile, ehogela nezinye, gxuma ngamunye, kuwukuziphulula amaphiko nomunye futhi amakhanda ziyanswininiza.

Ngo izinsikazi kulencane ovuthiwe ngokobulili, njengoba ichthyologists kulinganiswa, ososayensi, ubude umzimba 228 cm. Ukukhulelwa ihlala isikhathi esingangonyaka.

Bottlenose Dolphin, like iningi izilwane zasemanzini ezincelisayo - isilwane viviparous. Kid izalwa emanzini, njengoba umthetho, umsila phambili. ngezinye izikhathi General ukuqhubeka imizuzu engu-20, futhi ngezinye izikhathi yephuza ngamahora amabili.

ihlengethwa i-common - ihlengethwa i-common

Kuyinto izilwane social kakhulu nemindeni yabo. Abakwazi ukucabanga ngokuphila abo bodwa. Umhlambi amahlengethwa, kwezinye izimo minengi ngenani eliyizinkulungwane ezingamatshumi amabili.

amahlengethwa ezivamile aba imikhaya ehlanganisa ezizukulwane eziningana ukuze kukhululwe inzalo ka insikazi efanayo. Lactating abesifazane nabesilisa abasha, futhi ngezinye izikhathi zakha ehlukile, jambs ngokuvamile yesikhashana.

Lona esheshayo izilwane zasemanzini, isheshisa kuya ku-60 km / h. Lokho kulula ngokwanele ukuchaza. ihlengethwa i-common - dolphin encane. yayo obuphelele umzimba ingeqi imitha elilodwa. Azizange ngisho ukuhambisana ushaka.

amahlengethwa Phila zithuthelekela ikakhulukazi olwandle. Zidla on inhlanzi, mollusk ezinamagobolondo ngezinye izikhathi.

ukukhahlamezeka kwendawo

Kukholakala ukuthi Sea ihlengethwa, yize uhlala cishe zonke izilwandle nasolwandle amanzi amancane noma efudumele. Ngokusho ososayensi, ihlengethwa i-common ophila oLwandle Olumnyama iyindinganiso "Dolphin ubuhle."

izici yangaphandle

Lesi silwane has a ezilinganiselwe, umzimba mncane. On Uhlangothi ngalunye isithombe kunalokho eziyinkimbinkimbi - siphohlongo kwi background elimhlophe, okuyinto wanika igama ingqondo. Umbala - shades omnyama nomhlophe, futhi ezihlukahlukene grey.

Ukuziphatha ngokwemvelo

ihlengethwa i-common - a izilwane inobungane emhlambini. Bona ngokucophelela esiphatha ngayo abafowabo njengokungathi ogulayo ngokuhlanganyela ukuzingela inhlanzi, kulondolozwe futhi kuvikelwe leli ihlengethwa abasha. Ukuxhumana kwenzeka iphakethe nge imisindo - ukuchofoza, ntswininiza futhi umsindo. Ngokungafani afaliny, beaked 5 sisebenzisa imisindo imisindo ehlukene, iphimbo kanye ngamazwi.

Ebusika, amahlengethwa ubuthe nemihlambi emikhulu afika ku abantu abayizinkulungwane ezimbalwa. Kwathi kuqambe kufika ihlobo ngokuvamile ukubola bese ukudala amaqembu amancane amahlengethwa ezivamile. Emikhayeni enjalo - ubuhlobo obuseduze kakhulu phakathi kwawo wonke amalungu alo.

I-akhawunti ezimweni lapho lezi amahlengethwa ekusizeni izilwane ubudala wawugcinwa phezu kwamanzi ukuze bakwazi ukuphefumula.

Ihlengethwa itheku vaquita

Amaphiko pectoral komtshina babanjwa. Umhlane is ababethi amnyama-grey, isisu awube mhlophe. Ubude lesi silwane ingeqi 1.8 m Isisindo sayo -. 30 kg.

ukukhahlamezeka kwendawo

Ihlengethwa harbor porpoises e Sea ngasogwini ihlangabezana unyaka wonke, ngasogwini we Azov livela kwentwasahlobo. Ngo ekwindla, lezi zilwane siyekele jambs silverside futhi anchovy.

Ngeminye iminyaka, lwaluyophola abukhali futhi glaciation ngisho Sea Azov zaholela ekufeni kwalezi zilwane eqhweni.

Ayevame ukuchitha ubusika ngasogwini South eCaucasus and eCrimea. Lezi amahlengethwa bahlala ngamaqembu amancane abantu 5 kuya ku-30, kodwa kukhona esisodwa (akuvamile).

Ehlobo lika itheku porpoises kungabonakala le Kerch Strait lapho ukuzingela mullet. Lokhu ihlengethwa sivame ukufika emfuleni.

Ubude bempilo - engu-12 ubudala, izinga lokuzala kufinyelelwe iminyaka engu-4. Ukukhulelwa ihlala kwezinyanga ezingu-11, amawundlu bazalwa ngoMeyi-Agasti. Inzalo female suckle izinyanga 5-6.

Powered itheku vaquita goby, anchovy, silverside nezinye izinhlanzi ezincane. Daily ihlengethwa itheku vaquita odla ezingaphezu kuka 5 kg izinhlanzi.
