Amahlengethwa sekuyisikhathi eside engenye yezilwane zamanzi ezithandwa kakhulu ngabantu. Futhi lokhu akumangazi! Ngemuva kwakho konke, amahlengethwa yizidalwa ezinokuthula kakhulu, ezihlakaniphile futhi ezinobungane emhlabeni! Uma sikhuluma ngamahlengethwa, njalo phambi kwamehlo ethu sicabanga ukuthi ama-cetacean aqeqeshiwe enza ama-acrobatic stunts. Kodwa-ke, kunamazwe aphikisana kakhulu namahlengethwa, akholelwa ukuthi lezi zidalwa ezihlakaniphile akufanele zihlale ngaphandle kwemvelo, ngoba inani lamahlengethwa lehla kakhulu unyaka nonyaka. Futhi yisici somuntu kuphela okufanele sisolwe ngalokhu.
Umlando omncane
Kucatshangwa ukuthi i-sperm whale, i-whale, ihlengethwa, kufaka phakathi ingulube yasolwandle, yehla kokhokho abafanayo - izilwane ezincelisayo ezazihlala emhlabeni izigidi zeminyaka edlule, kepha zazingezona izilwane zasendle kuphela, kepha zazithanda ukuzingela nokuhlala emanzini. Lawa angama-mesonychids - izidalwa ezithanda omnivorous ezinezinselo ezinjengamahhashi nezinkomo, ezinokubukeka okufana nezimpisi. Ngokwezibalo ezinzima, iMesonychids yaphila iminyaka engaphezu kwezigidi ezingamashumi ayisithupha, futhi bahlala ezwenikazi lamanje lase-Asia, ingxenye yoLwandle iMedithera (ezikhathini zasendulo kwakunguLwandle lwaseTethys). Lezi zilwane, cishe, zazidla noma yiziphi izilwane zasemanzini ezinesisindo esimaphakathi kanye nanoma iziphi izinhlanzi ezabe zihlala emaxhaphozini amaningi asogwini.
Futhi ngenxa yokuthi ama-mesonichids achitha iningi lempilo yawo kunoma yimuphi umzimba wamanzi, ukubukeka kwawo kwaqala ukukhula ngobubanzi, ukugeleza nxazonke, izitho zaphenduka zaba amaphiko, ngenkathi izinwele esikhunjeni zaqala ukunyamalala, futhi amafutha angaphansi kwesikhumba akhula futhi anda ngaphansi kwawo. Ukwenza kube lula ukuthi izilwane ziphefumule, amakhala ayayeka ukufeza umsebenzi wawo wokuqala: ngesikhathi sokuziphendukela kwemvelo, aba isitho esibalulekile esilwaneni, ngoba izidalwa zikwazi ukuphefumula ngazo, futhi konke ngenxa yokuhamba kwazo phezulu ekhanda.
Ngisho noma isikhathi eside bekukholelwa ukuthi okhokho bama-cetaceans, kufaka phakathi amahlengethwa, bangama-mesonychids ngempela, noma kunjalo, ngaphezu kwakho konke "baboleka" ezimvubu, futhi lokhu kufakazelwa yizifundo eziningi zamangqamuzana. Amahlengethwa akuzona nje izizukulwane zala ma-artiodactyls, asafana ngokujulile futhi ayingxenye yeqembu lawo. Kuze kube manje, izimvubu nezimvubu zihlala ikakhulukazi emanzini, emhlabeni zingamahora ambalwa kuphela okufanele zidliwe. Yingakho ososayensi bephakamisa ukuthi izimvubu zingenye yamagatsha okuziphendukela kwemvelo ama-cetaceans. Ukuthi nje imikhomo isihambile ukudlula izimvubu, imvamisa ishiye impilo emhlabeni futhi ishintshela ngokuphelele emanzini.
Futhi uma kubonakala kukuxaka kuwe ukuthi izimvubu nezinselo zihlobene nama-cetaceans angenamlenze, khona-ke sifuna ukunikeza enye inguqulo ye-taxonomy, ngokwesibonelo, izilwane zomhlaba ezinemilenze emi-4 eyavela enhlanzini. Kalula nje, akumele kusimangaze ukuthi selokhu impucuko yethu yavela, ukuvela kwamahlengethwa kwahamba ngokushesha okukhulu.
Incazelo yamahlengethwa
Amahlengethwa yizilwane ezinkulu zasemanzini eziphefumula umoya, ngokungafani nezinhlanzi, umsebenzi wazo ohlinzekwa yimigodi. Amahlengethwa asolwandle asemanzini wonke amahora angama-24, futhi lapha azala amahlengethwa amancane. Njengoba insikazi izondla izingane zayo uqobo, ngakho-ke ziyizidalwa ezinegazi elifudumele, izilwane ezincelisayo.
Ngokungafani nezihlobo zabo - imikhomo, amahlengethwa yizidalwa ezinhle kakhulu. Ngaphandle kwamazinyo abukhali ekubukeni kwabo okuhlakaniphile nobungane, umuntu akakwazi ukuthola izingqinamba eziyingozi. Ngakho-ke, ihlengethwa elidala lingaba ngamamitha ayi-2,5 ubude, linesisindo esingamakhilogremu angamakhulu amathathu kuphela. Ngenkathi umkhoma obulalayo ungaba ngamamitha ayisishiyagalolunye ubude futhi ube nesisindo samathani ayisishiyagalombili. Abesilisa bahlala njalo bebakhulu kunabesifazane okungenani amasentimitha angama-20. Banamazinyo angaphezu kwamashumi ayisishiyagalombili. Umbala wesiqu namaphiko amnyama noma mpunga, kanti isisu simhlophe.
Isitho esikhulu kunazo zonke Ihlengethwa okuthiwa i-cetacean dolphin linobuchopho obuphaphama ngokumangazayo ngaso sonke isikhathi lapho leli dolphin lilele. Ubuchopho buvumela isilwane ukuthi siphefumule ngaso sonke isikhathi, noma ngabe silele: ngale ndlela ihlengethwa ngeke limuke, ngoba ukunikezwa kwe-oksijini kuma-cetaceans kubaluleke kakhulu empilweni.
Ososayensi babize isikhumba sehlengethwa njengesimangaliso semvelo. Lokhu yingcebo yabo! Lapho amahlengethwa eqeda ngokuthula uthuthuva lwamanzi, lapho umzimba udinga ukwehla kancane.

Abaklami bemikhumbi baye babheka ngokucophelela ukuthi amahlengethwa abhukuda kanjani isikhathi eside. Ngenxa yamahlengethwa, abaklami bakwazile ukudala isikhumba esenziwe ngomkhumbi-ngwenya.
Amahlengethwa: adlani nokuthi azingela kanjani
I-Shellfish, izinhlobo ezahlukahlukene zezinhlanzi nezinye izilwane zasemanzini ukudla kwehlengethwa. Kuyathakazelisa ukuthi amahlengethwa angadla izinhlanzi eziningi ngosuku. Amahlengethwa azingela izinhlanzi ezikoleni, futhi ilungu ngalinye lawo lingadla kuze kufike kumakhilogremu angamashumi amathathu... Konke lokhu kungenxa yokuthi amahlengethwa ayizilwane, ezindaweni eziphansi kakhulu zamazinga okushisa olwandle noma amanzi olwandle (ngaphansi kuka-zero degrees Celsius), okumele zihlale zigcina ukushisa kwazo ukuze zikwazi ukusebenza kahle. Futhi kusiza amahlengethwa anegazi elifudumele kula mafutha aminyene angaphansi, ahlala egcwaliswa ngenxa yenani elikhulu lokudla. Yingakho amahlengethwa ehlala ehamba, ezingela, futhi ebusuku kuphela avumela ukuphumula okuncane.
Isikole samahlengethwa singashesha ukuthola isikole sezinhlanzi, ngoba olwandle lezi zilwane zingama-aces. Uma amahlengethwa asevele eseduze nolwandle, ngokushesha akha izindandatho ezizungeze izinhlanzi ukuze acindezele ukudla kwazo kwesikhathi esizayo emanzini angajulile, bese edla lapho. Ngokushesha nje lapho amahlengethwa ethola izicathulo zezinhlanzi zithunjiwe, awazijahi masinyane, kepha bese eqhubeka nokuzigcina zizungeze ukuze zingabhukudi, futhi ilungu ngalinye lomhlambi lingathola isidlo sasemini noma isidlo sakusihlwa ngokudla elikuthandayo.
Ukuze ubone amahlengethwa, kwanele ukuthola isikole sezinhlanzi. Ngokufanayo, la ma-cetacean azohlala lapho kunezinhlanzi eziningi khona. Ehlobo, amahlengethwa angahlangana ngokugcwele e-Azov, lapho i-mullet ne-anchovy ihambela olwandle ukuyokondla. Amahlengethwa abuye abhukude asondele osebeni lwaseCaucasus ekuqaleni kwekwindla, lapho izinhlanzi ziqala ukufuduka ziyimihlambi.
Njengoba ukwazi ukubona, kuyaqabukela ukubona ihlengethwa elilodwa olwandle, ngoba lezi zilwane zinobungane kakhulu, zithanda ukuhlala emihlambini, zizingele ndawonye zize zigxume kahle futhi zenze ubuqili bazo amahlengethwa akwazi ukusebenzisana nozakwabo. Noma ngabe bekuyini, kepha amahlengethwa awazange azwane nemikhomo ebulalayo. Futhi, kusekhona abazingeli abazingela lezi zidalwa zomhlaba ezinobungane. Naphezu kwakho konke, amahlengethwa athembela kubantu futhi aze azi nokuthi angaxhumana kanjani hhayi kuphela, kodwa futhi nezinye izilwane. Abasoze bashiya amaqabane abo enkingeni. Futhi uma kunengozi enkulu, bangasiza ngisho nomuntu. Zingaki izinganekwane nezindaba emhlabeni ezikhona ngamahlengethwa asindisa izimpilo. Abanye baze babuka lapho amahlengethwa edudula izikebhe ezazipheshulwa ngumoya zibheke ogwini.
Ukuzalisa ihlengethwa
Ngokungafani nezinye izakhamizi zomhlaba zasemanzini, amahlengethwa yiwo kuphela azalwa enemisila, hhayi amakhanda. Futhi kunjalo. Omama abanothando abawashiyi amawundlu abo ngisho eminyakeni emibili noma emithathu ngemuva kokuzalwa.

Amahlengethwa ayizilwane ezingokwemvelo futhi ezinesihawu. Ihlengethwa elincane, noma selizimele ngokuphelele, owesilisa noma owesifazane omdala, akalokothi, ngaphansi kwanoma yiziphi izimo, alahle abazali bakhe.
Futhi amahlengethwa azizwa ethanda kakhulu hhayi kuphela abafowabo, kepha ngisho nemikhomo, ezinye izilwane (azithandi imikhomo ebulalayo) nabantu. Ngemuva kokuba owesilisa nowesilisa bezele amawundlu, abaze bahlukane, noma sebethole amawundlu amaningi. Obani, uma kungenjalo amahlengethwa, abakwaziyo ukuthanda amawundlu abo, asebenzelane nabo ngobumnene nangothando, abafundise, abathathe bazingele nabo, ukuze maduzane izingane ngokwazo zizokwazi ukuzingela izinhlanzi.
Kuyathakazelisa!
Uma amahlengethwa ezingela futhi ezizwa engozini, ahola izingane zawo ngemuva, kepha uma kungenazinsongo zangaphandle, amawundlu amahlengethwa abhukuda ngokuzola ngaphambi kwabazali bawo. Kuyathakazelisa ukuthi ngemuva kwezinsizwa, abesifazane bayabhukuda, bese kuthi abesilisa babe ngabavikeli.
Ubudlelwano nabantu
Njengoba ihlengethwa ngalinye nezinhlanga zakubo kanye nemikhomo zihlala ngokuthula nangokuzwana, khona-ke uziphatha ngokufanele. Umuzwa wosizo kulezi zilwane wenziwa ikakhulukazi. Abasoze bashiya ihlengethwa eligulayo ukuze bafe, bazosindisa ngisho nomuntu ominzayo olwandle, uma, kwenzeka ngengozi, bazithola beseduze. Amahlengethwa ayokuzwa ukukhala kosizo komuntu kude, ngoba ukuzwa kwabo kuthuthuke kakhulu, kanye nengxenye yobuchopho.
Iqiniso ukuthi amahlengethwa achitha sonke isikhathi sawo emanzini, yingakho amehlo abo engaboni kahle (ukungabi namanzi okubuthakathaka). Lapho-ke ukuzwa kuthuthukiswa kahle kakhulu. Ihlengethwa lisebenzisa indawo esebenzayo - ukuzwa kukwazi ukuhlaziya i-echo eyenzeka lapho yenza imisindo yesici kunoma yiziphi izinto ezizungeze isilwane. Ngokuya ngalokhu, i-echo itshela ihlengethwa ukuthi imile kanjani, zinde kangakanani izinto ezizungezile, ukuthi zenziwe ngani, ngokujwayelekile, ukuthi ziyini. Njengoba ukwazi ukubona, ukuzwa kusiza ngokuphelele ukufeza indima ebonakalayo yedonphin, engavimbi lesi sidalwa esithanda ukuthula ukuba sizizwe sigcwele ezweni eliyinkimbinkimbi kanjalo.
Kulula ngabantu ukuthambisa ihlengethwa. Ngenhlanhla, njengenja, isilwane kulula futhi kulula ukusiqeqesha. Umuntu kufanele ahehe ihlengethwa ngenhlanzi emnandi. Uzokwenzela umphakathi noma yikuphi ukuphenya. Yize amahlengethwa enephutha elilodwa, angakhohlwa noma yiliphi iqhinga ngokushesha okukhulu uma umuntu ekhohlwa ukumondla ngesikhathi.
Kungani sonke siphatha amahlengethwa ngokungafani nezinye izilwane. Uma ubheka lezi zidalwa ezinhle nezihlekisayo, uyakhohlwa ukuthi zinkulu kangakanani lezi zilwane, nokuthi, naphezu kobungako bazo, zingukuphela kwama-cetaceans angahlukaniswa ngokuphepha ngokuthi "abangane" abangcono kakhulu.
Amahlengethwa, njengogogo abasebhentshini ilukuluku ngokweqile... Babhukuda baya kulowo muntu ngentshisekelo, badlale ngothando naye, baphonse ibhola, futhi bamomotheka, yize bembalwa abantu abakubonayo lokhu. Bahleleke kahle, bayasimamatheka, bahleke nathi. Asikwazi ukubiza ubuso behlengethwa ngomlomo, ukumamatheka ebusweni - ukuthokoza nobungane - yilokho okusidonsela kubo!
Amahlengethwa ayasithanda, siyawathanda. Kepha kukhona ... abantu abangenanhliziyo abathi, ngenxa yenzuzo, bakhohlwe ngesintu futhi babulale lezi zidalwa ezinokuthula. EJapan, ukuzingelwa kwamahlengethwa kufana nesiphuzo! Abacabangi ngisho nokukhuluma ngozwelo lwamahlengethwa. Kwamanye amazwekazi, amahlengethwa ahlaliswa kumahlengethwa ukuze ajabule abantu. Ezimweni eziminyene, lapho bengahlali khona isikhathi esingaphezu kweminyaka emihlanu (uma kuqhathaniswa, ngokwemvelo, amahlengethwa aphila kuze kube yiminyaka engamashumi amahlanu).
Kuyathakazelisa!
Umbuso waseNdiya waba ngowesine emhlabeni ukuvimbela ukwakhiwa kwamahlengethwa. Abokuqala ukuvimba la ma-cetaceans ekuthunjweni kwakungu-Chile yase-Asia, iCosta Rica, kanye naseHungary. KumaNdiya, amahlengethwa awafani nomuntu onelungelo lenkululeko nokuphila ngokwemvelo.
Ukwelashwa kwehlengethwa
Umlando wobungani obukhulu obuphakathi kwamahlengethwa asolwandle nabantu ubuyela emuva ibanga elide, ngisho nangaphambi kokuba ososayensi baqale ukubiza lezi zilwane ngamahlengethwa. Abaphenyi bolimi lomzimba lwe-cetacean baphethe ngokuthi bakhulise amakhono wokukhuluma ngamazwi njengabantu. Uma ingane egula ngengqondo, i-autistic, ichitha isikhathi esiningi namahlengethwa futhi "ixhumana" nabo, khona-ke lokhu kunomthelela omuhle kuye. Ingane iqala ukumamatheka, ihleke. AbaseBrithani bakhulume ngalokhu emuva ngama-70s wekhulu leminyaka elidlule. Ngokulandelayo, ukwelashwa kwamahlengethwa kwaqala ukusetshenziswa ngokuzikhandla ukwelapha hhayi izifo zengqondo nezengqondo kuphela, kepha futhi nezingi zomzimba. Ukubhukuda namahlengethwa ndawonye kuyasiza, kungakhulula ukucindezeleka, ikhanda elibuhlungu, ama-neuralgias kanye ne-rheumatism.
Okuzenzakalelayo kokuziphatha
Nonke, mhlawumbe ezindabeni noma kwi-Intanethi, nibuke isithombe esinjalo lapho amabhishi agcwele amahlengethwa angavumelekile. Imvamisa zona uqobo ziyalahlwa, ngoba zigula kakhulu, zilimele, noma zifakwe ushevu. Amahlengethwa ayizwa kahle imisindo evela ogwini, ecishe ifane nokukhala kokucela usizo kozakwabo. Ngakho-ke, lapho ezwa ukukhala okunjalo, amahlengethwa aphuthuma ogwini ayosiza, futhi avame ukubanjwa.
