Keith - nsomba kapena nyama? Zosangalatsa za zinsomba

Keith - nsomba kapena nyama? funso lovutali asayansi kale kubwera kwa sayansi yamakono. Makamaka, vutoli anali kuyesera kusankha ngati wanzeru lingaliro, ngati Aristotle. Chotero anazindikira yemweyo kuti m'nthawi yathu. Koma tiyeni onse mu dongosolo.

Keith - ichi ndi anthu ambiri otchuka thambo madzi. Ndi kukula kwake ndi chisomo n'zosayerekezeka ndi cholengedwa aliyense wamoyo, osanenapo mphamvu yodabwitsa nyimbo. Koma kodi wina tikudziwa za zolengedwa izi zosaneneka?

chinsomba ndi ndani?

Nanga tanthauzo mwa chinsomba? Malinga ndi dikishonale, ndi nyama zazikulu amene amakhala mwa nyanja. Ndiko kunena kuti, mosiyana ndi kale, kupeza njira yothetsera zimenezi nkhani opiringizidwa zosavuta. Koma kodi n'chiyani kuti mbadwa ya chinsomba wakale ankafuna kusinthitsa dziko m'nyanja?

Chabwino, choonadi chonse, asayansi sakudziwa. Komabe, amadziwika kuti zaka 60 miliyoni zapitazo makolo a m'madzi zimakhala onse, anapita kukafuna chakudya chawo kumbuyo m'madzi. Mwina zimenezi zinachititsa kuti chilala yaitali, amene anawononga mbali ya zomera pa dziko, kapena kwambiri kupikisana ndi nyama ina. Koma mfundo ndi yakuti - makolo a zinsomba sakufunanso kupita kudziko.

Kodi nyama dziko wakhala ndinazolowera moyo m'madzi?

Iwo ayenera kumvetsa zimenezi metamorphosis zimachokeradi mu zaka imodzi kapena ziwiri. Evolution - ndi unyolo kusintha kakang'ono kamene kupanga kwa zaka chamoyo wamoyo nthawi zonse mutating. Patapita chibala zonse zatsopano tione, ndi mwapadera kwa makolo ake.

Komabe atatha zaka 60 miliyoni ofufuza ankaona mu chinsomba mafupa dongosolo kumatikumbutsabe nthawi akale, pamene iye anayenda pa yoteroyo ake anayi pa dziko. Mwachitsanzo, ali ndi ntchafu fupa, limene lili mu gawo kumbuyo kwa thupi. Komanso, zipsepse zake kutsogolo amenewa dongosolo fupa ndi ambiri a nyama zokhala-hoofed.

Popeza anamaliza maphunziro ambiri a asayansi zija chidwi. Iwo likukhalira kuti abale ogwirizana m'madzi zimakhala ndi mvuu. Ndipo ngati inu kuyang'anitsitsa, pali kufanana mu khalidwe lawo Tingaone ngakhale lero. Makamaka cholinga chawo chachikulu madzi.

Banja la m'madzi zimakhala

Tikumbukenso kuti chinsomba - si woimira yekha ndi banja lake. Dolphins ndi porpoises ali m'gulu gulu la nyama zam'madzi. Kodi amasiyana anthu ena zinandivuta madzi?

• Choyamba, zinsomba onse magazi ofunda, mosiyana ndi nsomba. Ndicho chifukwa chake iwo ali kwambiri zosowa za thupi wabwino mafuta kuti angawateteze ku kuzizira ufumu m'madzi.
• Chachiwiri, banja sangathe kuchotsa mpweya ndi madzi. Motero, ayenera nthawi zonse pamwamba, kuti ankatunga wake wa mpweya m'mapapo.
• Chachitatu, iwo kudyetsa ana awo mkaka. Ngakhale pa zaka zamoyo wa ndondomeko izi pang'ono adasandulika, m'madzi zimakhala adakali nyama.

Banja lonse m'magulu atatu lalikulu:

• Baleen zinsomba (Mysticeti) - ndi detachment waukulu wa banja. Maonekedwe ake amadziwika chifukwa chapadera fyuluta thupi "whalebone", limene lili nsagwada chapamwamba nyama. ntchito yake yaikulu - imathandiza zomera ku zodetsa osafunika.
• Imodzi zinsomba (Odontoceti) - ndi ogwirira lalikulu, preying pa nyama ndi nsomba zina zing'onozing'ono. mitundu amatha kuyenda m'madzi ntchito echolocation.
• Ancient zinsomba (Archaeoceti) - mwatsoka, osati nthumwi umodzi wa gulu, sitingakhale ndi moyo mpaka masiku athu.

Zinsomba: onse mudziwe

M'gulu la anthu dziko lonse lapansi chinsomba - ndi nyama yaikulu kwambiri. Wapakati wamkulu munthu angafikire mamita 25 m'litali. Yerekezerani ziri chomwecho kutenga mabasi 4 lalikulu, ngati aika mu mzere. N'zosadabwitsa kuti chinthu chachikulu umalemera pafupifupi 90-110 matani, ndi zina zambiri.

Zimphona izi moyo pafupifupi nyanja za padziko lapansi. Kodi zoona, iwo akhoza amasamukira kumalo wina malingana ndi nyengo. Khalidweli ndi chifukwa chakuti zinsomba amazindikira madzi kutentha, choncho yozizira akupereka pafupi ndi kotentha.

Cacikulu, pakati pa mamembala onse a banja akhoza kuwasiyanitsa subspecies awiri osiyana: buluu ndi imvi zinsomba. Mokulira mugawo ili ndi chifukwa mtundu wa khungu la nyama zimenezi, koma pali zina, kusiyana n'kofunika.

kumatikumbutsabe a m'mbuyomu

Gray chinsomba - ndi woimira wamkulu wa banja. Asayansi apeza zotsalira za nyama pa kusanthula akhakula anali pafupifupi mamiliyoni zaka 30. Poyamba, zimphona izi ankakhala pafupi ngodya zonse za dziko lapansi, koma tsopano iwo lingapezeke mu gawo la kumpoto kwa Pacific Ocean.

Zilombozi ankakhala moyo mu magulu a pafupifupi 2-3 anthu lililonse. Ngakhale kuti nthawi zambiri kukumana ndi chinsomba yekhayo monyadira akulima mipata madzi. Koma ambiri a Zimphona amakonda kukhala gulu. Ndi chachikulu ichi ndi chifukwa chakuti chinsomba imvi ali kwambiri mwamphamvu apanga ubale banja.

Mwina ubale awathandiza apulumuke nthawi yoopsa. Ndipotu, mu zaka za m'ma XX iwo pafupifupi anawononga whalers, kufuna mafuta awo. Choncho, malinga ndi asayansi, mu 1946 chiwerengero cha nyama izi anachepetsedwa anthu 250. Mozizwitsa, ndi khama la ufulu nyama anakwanitsa kupeŵa zoopsa. Tsopano chiwerengero cha nyama chawonjezeka mpaka 30 chikwi., Kuti anawapatsa chiyembekezo cha tsogolo labwino.

Nangumiyu - cholengedwa yaikulu padziko lapansi

Koma anangumi amaonedwa kukhala zolengedwa yaikulu pa dziko lino lapansi. Ngakhale oterowo nyama zikuluzikulu monga njovu, amalephera kupikisana nawo. Miyeso awa kukumbutsidwa kuti pamene chinachake chonga zimphona anayenda padziko lonse Lapansi. Tsopano, Nangumiyu - yekha woimira nyama wakale zimphona.

Nyama imeneyi si makamaka kuonera anthu, choncho kawirikawiri akuyandikira gombe. sing'anga amalikonda ndi nyanja lotseguka, kumene akumverera kumasuka kwambiri. Iye amasuntha pang'onopang'ono ndithu, koma ndi liwiro 10-12 Km / h, koma mwadzidzidzi izo kuwonjezera atatu khola.

Ngati mamembala onse a mitundu wake, chinsomba buluu wakudya zomera. Ndipo ngakhale nyama zimenezi kale m'malo m'dziko madzi, mmenemo, komabe sangathe. N'chifukwa chake zinsomba nthawi tiwolokere pamwamba, motero kumasuka madzi akasupe kutsegula wapadera pamalo thupi chapamwamba.

kubalana zinsomba

Zinsomba - nyama nyanja, amene manambala nthawi zambiri yafupika kuchepetsa zoopsa. Izi zimayambira pa anthu kusaka nyama zawo ndi mafuta. Ndi iwo amene ali culprits chachikulu cha mavuto amenewa, koma si okhawo.

Chinanso zokhudza anthu a mitundu iliyonse, ndi mphamvu yake kubereka. Choncho, vuto lagona pa choona kuti zolengedwa zimenezi zimachititsa ana sanabadwa kuposa kamodzi aliyense kapena zaka ziwiri. Ndipo pamene mkazi chibala chinsomba chimodzi chokha pang'ono, osachepera - awiri. Pa nthawi yomweyo, malingana subspecies zinsomba mimba ukhoza pakati pa 9 ndi 18 miyezi.

Zosangalatsa chakuti amayi nthawi zonse amasamalira ana ake. Anthu nawonso, kukula mofulumira ndi kupeza kulemera. Kotero, pafupifupi patsiku shorthead mupeze za makilogalamu 50 a kulemera moyo. Choncho musadabwe kuti ena miyezi seveni, iye akhoza vymahal mpaka mamita 14 m'litali ndi kulemera tonnes 20-25 kanthawi.

Ndipo ngakhale msinkhu zinsomba abwera pa zaka 4-5, zonse kunachitika, wamkulu aliyense payekha ali 14-15 yekha, m'chaka cha moyo wake.

Keith: Chidwi Mfundo

anthu ochepa mukudziwa kuti:

• Zinsomba - wina Munthu amene angayimbe. Ngakhale kuti poyamba ankaganiza kuti luso limeneli ndi okhawo amuna, kafukufuku wa posachedwapa akhala zosiyana. Momwemonso, zinsomba wamkazi kuimba nyimbo, makamaka pups pang'ono.
• A zonse m'mimba Nangumiyu ungasunge matani awiri chakudya moyo. Mwachitsanzo nsomba yomweyo kutenga pafupifupi mabwato ophera nsomba.
• Ngati ife kulankhula za kulemera kwa nsomba, tiyenera kukumbukira kuti munthu wa lilime lake umalemera pafupifupi 3 matani. Koma matupi zina, mwachitsanzo, mtima angafikire makilogalamu 600-700.
• Ngakhale China anakhalabe fupa m'chiuno, ndi wopanda ntchito. Komanso ngakhale olumikizidwa kwa gawo lalikulu la mafupa a.
