Kodwa ke phezu kwalo ithandwa kangaka ehlabathini dolphins nanamhlanje lundanda i aura imfihlelo. Ke kaloku omnye eemfihlelo: ngubani na ezi zidalwa ezimangalisayo? Le ntlanzi okanye akunjalo?

imfihlakalo ezazingekho

Dolphin - playful abemi kweelwandle, nto leyo ifumaneka kwiindawo ezininzi zomhlaba. Ekubeni ehlala emanzini, abantu abangenawo baqhele ukucinga ngayo njengoko bephuma kweentlanzi. Ngapha koko, yiyiphi enye indlela umntu ukuchaza into yokuba akanako achithe iiyure ukuba zidade ngaphezulu? Kwisigqibo esifanayo izaphetha zabo kwaye ubukho amaphiko, leyo lophawu ebalulekileyo bonke abemi bobukumkani kwamanzi.

Noko ke, izazinzulu wabancina iimpawu ezi zidalwa bafika kwisigqibo eyahlukileyo ngokupheleleyo. Ngokutsho uphando lwabo, le ngxaki eku - ummeli kwiklasi ezincancisayo. Kunye nezalamane zalo ekufuphi kukho iminenga, iminenga umbulali kunye neemazi ulwandle. Kodwa kutheni kunjalo?

ubungqina obungenakuphikiswa bani

Isibakala sokuba le ngxaki eku - esiyimamali lo, ngokutsho izinto ezininzi. Ayikwazi bamlahla kuzo, ngoko ke ihlala kuphela ukuthatha le mbono. Ngoko nantso kutheni le ngxaki eku - akukho nto intlanzi:

1. Abayi kuba iigilizi, kwaye endaweni ngokuba abantu ukukhanya ukuyisebenzisa. Mababe ahluke kancinane kulawo ezikhoyo ezincancisayo ezisentlabathini, oko enye kwaye nomzimba efanayo.
2. Zonke iidolphin ezinegazi elishushu. Loo msebenzi engazange ibonwe iintlanzi.
3. Ezi zidalwa ezithandekayo uzale ubomi inzala, kunokuba ukubeka amaqanda, ngathi noogxa babo kwamanzi.
4. Iphila ubisi abantwana. Kungenxa yoko le nto zidluliselwa udidi ezanyisayo.
5. Kwaye ekugqibeleni, ezincina amathambo dolphins, oosonzululwazi baye bafumana eninzi ubungqina ukuba ngemihla yamandulo, ezi zidalwa ulwandle wahamba ilizwe.

Kodwa kwenzeka njani ukuba itshintshe ezihlala wabo kwizikhewu emanzini? Yintoni eyabangela ukuba bafudukele kwihlabathi elitsha? Yintoni libali lokwenyaniso njengedolphin? Kwaye ingaba kukho izibakala ukuqinisekisa nto?

Izizathu isicelo esibhaliweyo sokutshintsha yokuhlala

Enyanisweni, dolphins - asingobantu kuphela izidalwa abatshintshayo element omnye komnye. Umzekelo, ityala idumileyo xa izinto eziphilayo andishiye ubunzulu emanzini waza waqalisa ukuhlola ilizwe. Noko ke, kulo mzekelo, kwathi ngenye indlela ngeenxa zonke. Nangona kunjalo, akukho nto kubalulekile ukuba ibali. Kuba kubaluleke kakhulu nangakumbi le nto kusifikeleyo oku kwenzeke.

Apha izazinzulu, ngelishwa, aninako ukufika kunye uluvo enye. Kodwa ke, mhlawumbi, isizathu yaba nokunqongophala kokutya kweli lizwe, nto leyo esisizathu sokuba ezinye iintlobo kuye kwafuneka ukuba baziqhelanise ngeendlela ezahlukeneyo ukuzingela. Ngokukodwa, iminyanya zonke iintlanzi, kuquka dolphins, funda ukubamba phantsi kwabo amaxhoba. Oku kwakhokelela ukuba yokuba beye baba ngakumbi uchitha ixesha elininzi kufutshane imizimba yamanzi, akayi kushukunyiswa ngokupheleleyo kubo.

Yokuba ingxelo yefosili

Ngokumalunga ubungqina zembali, ezinye paleontologists baye bakwazi ukwenza irekhodi echanekileyo noko izakhi iintlanzi. Ngokuqhelekileyo, liye ezibukweni, kodwa hayi kakhulu kangaka ukuba ayicacanga yonke mfanekiso.

Ummeli endala iintlanzi ngu pakitsetus. isidumbu sakhe afunyanwa kwi kummandla Pakistan namhlanje, yaye izazinzulu kuqikelelwa ukuba akukho ngaphantsi kwezigidi 48. Iminyaka. Ngaphandle lo yezilwanyana njengenja oko nje imilenze yakhe ezingcakacileyo lwaphela neenzipho ezincinane eminweni yakhe. Baphila imizimba kufuphi namanzi, ukutya okanye intlanzi, yaye ngaloo nto nkxu emanzini ukuze ukubamba ixhoba labo. Pakitsetus wakhokela yokuphila ngathi amatywina mihla. Ngoku makhe siqwalasele izinyanya kamva of iintlanzi:

• Enye manqanaba alandelayo zazivelela yaba pakitsetusa ambulocetus, owayephila 35 yezigidi. Kwiminyaka eyadlulayo. Le irhamncwa yaba ubungakanani omhle kakhulu: umzekelo, ubude bawo malunga 3-3.5 neemitha, ubunzima kufuneka ingahluka phakathi kg 300. Ngokwangaphandle, wakhangela ifana noxam kwaye baphile zombini emanzini kunye nomhlaba.
• Enye pakitsetusa ngqo kumnombo kwaba rodhocetus. imbonakalo zokubasa yezilwanyana elifana amatywina mihla, kodwa imihlathi evuthelweyo kunye nenani canines. Kwakhona imilenze, ekupheleni apho, mhlawumbi, wabeka inwebu, akwazi ukuba ukudada ngokukhawuleza ngaphantsi kwamanzi.
• Basilosaurus - yenye isalamane okunokwenzeka whales. Noko ke, izazinzulu ezininzi zikholelwa ukuba mhlawumbi usisizalwane iminenga obulala ngaphezu ukhokho dolphins lobuhlobo. Oku kungenxa yokuba basilosaurus abe ubungakanani enkulu, akwazi ukuba ukuzingela phantse bonke abemi yolwandle.
• Dorudon - basilosaurus umkhululi, owayehlala kunye naye kwixesha elifanayo. Anakho ibathwana kakhulu emzimbeni. Kuyabonakala ukuba ezi kwiminyanya dolphins ekugqibeleni kususa kubo imilenze ezingeyomfuneko wathabatha nesisila.

Iimfihlelo yomlando

Malunga dolphins ebhalwe amaphepha amaninzi zenzululwazi yaqhuba uphando oluninzi, kodwa namhlanje kusekho iimfihlelo ezininzi ezinxulumene zazivelela zabo. Ngokukodwa, nangoku izazinzulu abakwazi ukubona ezinye iintlobo apho order indawo lelinye. Kodwa ke into yokuba ezi zidalwa kanye wayehamba emhlabeni, akukho kwamathandabuzo.

Hi ndlela leyi, kunye nophuhliso yemfuza, iimfihlelo ezininzi iphela yaqala kancinci ancame izikhundla zabo. Kutshanje, izazinzulu ziye bafumana ulwazi umdla kakhulu. Kubonakala ukuba iimvubu ezi iintlanzi izihlobo ezikude. Nje omnye amanqanaba Ukusombuluka dolphins bemkile nzulu elwandle, kwaye iimvubu bagqiba ukuhlala kude nonxweme.

Kaloku, makhe sixubushe ezinye iimpawu zezi ezincancisayo. Okukhona esiyaziyo dolphins, lo yavney uba nguye umgca esohlukanisa le iintlobo zezityalo ezivela kwabanye abemi kweelwandle neelwandlekazi.
