Dolphin - nsomba kapena ayi?

Nthawi zonse kovuta kuti umadutsa dolphin akusonyezera, chifukwa kumene mungachite kuwona zolengedwa wachisomo ndi oseketsa! Choncho Dolphins chaka anatsegula m'mizinda yambiri mu chiyembekezo kukopa amaonetsa ambili. Koma ngakhale kutchuka izi yochititsa padziko anamgumiwa ngakhale lero liwutamira ndi aura chinsinsi. Ndipo chimodzi cha zinsinsi: amene ali timeneti chodabwitsa? Nsomba kapena ayi?

sangaganize chinsinsi

Dolphin - ndi ankasewera okhala nyanja, lomwe likupezeka mu madera ambiri a dziko lapansi. Popeza iye amakhala mu madzi, anthu sadziwa zambiri amakonda poganizira ngati thupi limodzi la mitundu ya nsomba. Ndipotu mmene aliyense angathe kufotokoza mfundo yakuti iye sangakhoze maola tiwolokere pamwamba? Mawu ofanana mauta awo ndi kukhalapo kwa zipsepse, amene lingaliro zofunika kwambiri pa anthu onse a ufumu m'madzi.

Komabe, asayansi anafufuza makhalidwe a zilombo anabwera mapeto chosiyana. Malinga ndi kafukufuku wawo, dolphin - nthumwi ya gulu la nyama. Ndipo achibale ake apamtima ndi anamgumi, wakupha zinsomba ndi ng'ombe nyanja. Koma n'chifukwa chiyani anatero?

umboni wosatsutsika

Popeza kuti dolphin - ndi nyama ali, malingana ndi zifukwa zambiri. Kodi si awatsutse, liri mpaka kokha kutenga lingaliro limeneli. Kotero ndicho chifukwa dolphin - si nsomba:

1. Iwo alibe makutu, ndipo m'malo otchedwa anthu kuwala ntchito. Asiyeni iwo wosiyana pang'ono kwa kulili nyama lapadziko, komabe limodzi ndi thupi lomwelo.
2. anamgumiwa onse magazi ofunda. Mbali wotero sindinamuwonepo nsomba.
3. Zilombozi wokondeka kubereka moyo ana, osati kuikira mazira, monga anzawo a m'madzi.
4. Iwo kudyetsa ana mkaka. N'chifukwa chake amatchedwa kalasi ya nyama.
5. Ndipo potsiriza, ndiyesa mafupa a dolphin, asayansi apeza kwambiri za umboni kuti m'masiku akale, zolengedwa nyanja anayenda dziko.

Koma bwanji kuti anasintha malo awo mwachizolowezi mu malo madzi? Kodi chinapangitsa kuti asamukire m'dziko latsopano? ndi nkhani yeniyeni ya dolphin ndi chiyani? Ndipo ngati pali mfundo kuti titsimikizire kuti?

Chifukwa kusintha malo okhala

Ndipotu, anamgumiwa - si zamoyo zonse, amene kusintha mchitidwe wina ndi mzake. Mwachitsanzo, nkhani chotchuka kwambiri pamene woyamba zamoyo anasiya kuya madzi ndipo anayamba kufufuza dziko. Komabe, mu nkhani iyi, izo zinachitika mwanjira ina padziko. Komabe, si kofunika kuti nkhaniyo. Pakuti chofunika kwambiri ndi n'chifukwa chiyani zimenezi zinachitika.

Apa asayansi, mwatsoka, sangakhoze kubwera pamodzi mu lingaliro limodzi. Koma, nthawi zambiri, chifukwa anali kuchepa kwa zakudya mu dziko, nchifukwa chake ena mitundu anasinthira njira zosiyanasiyana za kusaka. Makamaka, makolo a m'madzi zimakhala onse, kuphatikizapo anamgumiwa, kuphunzira agwire nyama awo m'madzi. Zimenezi zinachititsa chakuti iwo akhala ndi nthawi yambiri pafupi matupi a madzi, si kwathunthu anasamukira iwo.

Zakufa zakale zikusonyeza

Pankhani umboni wotsimikizira, ena zokwiriridwa akwanitsa kulenga mbiri ndi zolondola cha masinthidwe m'madzi zimakhala. Mwachibadwa, ali mawanga wakhungu, koma iwo siali choncho kwambiri pobisa chithunzi chonse.

Woimira wamkulu wa m'madzi zimakhala ndi pakitsetus. mtembo wake anapezeka m'dera la masiku ano Pakistan, ndi asayansi Akuti izo zosachepera miliyoni 48. Zaka. Kunja chinyama ichi chinali ngati galu ndizo basi miyendo yake woonda idatha chiombankhanga pang'ono pa zala zake. Iwo ankakhala pafupi ndi matupi a madzi, kudya nsomba kapena nkhanu, motero akhoza choviikidwa mu madzi kuti agwire nyama zawo. Pakitsetus zinachititsa moyo monga zisindikizo ano. Tsopano tiyeni tione makolo ina ya m'madzi zimakhala:

• Imodzi mwa magawo wotsatira wa kusanduka anakhala pakitsetusa ambulocetus, amene anakhala 35 miliyoni. Zaka zapitazo. mdani uyu anali kukula chidwi kwambiri: Mwachitsanzo, m'litali ndi za 3-3.5 mamita, ndi kulemera ayenera zosiyanasiyana pakati pa makilogalamu 300. Kunja, iye ankawoneka ngati ng'ona ndi moyo m'madzi ndi pamtunda.
• Wina mwachindunji mbeu pakitsetusa anali rodhocetus. Animal malasha anali kuoneka ofanana ndi zisindikizo ano, koma anali nsagwada elongated angapo canines. Iye analinso ndi miyendo, pa mapeto a omwe mwina anaika Kakhungu, polola kusambira kudya m'madzi.
• Basilosaurus - ndi wachibale wina angathe zinsomba. Komabe, asayansi ambiri akukhulupirira kuti mwina linali la wachibale zinsomba wakupha kuposa kholo la anamgumiwa wochezeka. Ichi ndi chifukwa chakuti basilosaurus anali kukula yaikulu, polola kusaka pafupifupi anthu onse a nyanja.
• Dorudon - basilosaurus wachibale, amene ndinakhala naye mu nthawi yomweyo. Iye ali ndi kufanana laling'ono kwambiri la thupi. N'zochititsa chidwi kuti izi makolo a anamgumiwa potsiriza kutaya iwo miyendo zosafunika ndinapeza mchira chipsyepsye.

Zinsinsi za mbiri

About anamgumiwa olembedwa mapepala sayansi ndi kumulondolera kwambiri cha kufufuza, koma lero pali zambiri zinsinsi kugwirizana ndi kusanduka awo. Makamaka, asayansi sangathe kudziwa mitundu ina imene kuti m'malo ndi wina. Ndipo komabe chakuti timeneti kamodzi padziko lapansi, palibe chikaiko.

Mwa njira, ndi chitukuko cha chibadwa, zinsinsi zambiri za chilengedwe anayamba pang'onopang'ono kusiya malo awo. Posachedwapa, asayansi apeza mfundo zochititsa chidwi kwambiri. Iwo likukhalira kuti mvuu ndi m'madzi zimakhala achibale. Monga mmodzi wa magawo a zamoyo wa dolphin ndi apita kwambiri m'nyanja, ndi mvuu n'kumaonera gombe.

Chabwino, tiyeni tikambirane mbali ina ya nyama izi. The zambiri Ife tikudziwa za anamgumiwa, ndi yavney amakhala ndi mzere umene umawalekanitsa mitundu anthu okhala zina za m'nyanja ndi m'nyanja.

otukuka nzeru

Kusewera ndi anamgumiwa ndi chidwi ndi kumwetulira aliyense wakuyang'ana iwo. Komabe, pang'ono kudziwa kuti kumbuyo khalidwe chinabisidwa wanzeru chidwi, chimasiyanitsa iwo ndi mbali yotsala ya nyama. Mwachitsanzo, kupikisana nawo mitundu yochepa ya anyani ali kunena amene ali pafupi ndi anthu.

Dolphins komanso ndi dongosolo kulankhulana zovuta zochokera manja ndi phokoso. Kudzera mwa iwo akhoza ntchito kayendedwe ndi kusaka ngati limagwirira bwino yolongosoka. Komanso, nyama zimenezi mwamsanga kuphunzira, kuloweza zithunzi latsopano ndi kayendedwe ndi liwiro zosaneneka. Makamaka chifukwa cha ichi iwo ali otchuka pakati asangalatsi maseŵeralo ndi asangalatsi.

zozizwitsa echolocation

Dolphins - mmodzi wa mitundu yochepa imene mungagwiritse ntchito mafunde oganiza kulankhulana ake. Mphamvu ya chizindikiro patali kuti mawu awo akhoza kuuluka kwa mtunda wa makilomita angapo. Rumor ali kuti m'mbuyomu, asilikali ntchito anamgumiwa monga zoyesera wanga m'madzi, monga iwo angakhoze kupeza zipangizo zoopsa ngakhale madzi ambiri turbid komanso chozama.

Chikhalidwe choyipa anamgumiwa

Anthu amakhulupirira kuti nyama ndi ochezeka kwambiri, ndi khalidwe la iwo ngati ana. Dolphin - kwenikweni wankhanza kwambiri chirombo. Ndipotu, iye ndi mdani weniweni ndi kudya chilichonse wolephera iye kukula.

Komabe, achiwawa koposa m'makhalidwe ake ndi kupanga kusankha kwa ana. Choncho, ngati dolphin ng'ombe wabadwa ofooka, iye timuphe iye. Osanenapo chakuti pali milandu kumene zilombo pomenyana anthu ena a mtundu wawo, kumenyera dera kapena chifukwa cha chidani munthu.
