Ambiri mwa kudziwika kuswana spawning nsomba, koma osati onse. Anthu ena m'madzi ngati Aquarium ndi chilombo, ana awo wabadwa. Choncho, mafani zambiri zomera za m'madzi chidwi funso la mtundu wanji wa nsomba viviparous ndi mmene kubereka.

Nsombayi

Nsombayi ambiri amadziwika kuti ndi viviparous. Mwachitsanzo, mitundu ina monga kambuku, herrings chlamydoselachus, hammerheads ndi zina. Komanso pa mndandanda, pali Nsombayo buluu. Kukula kwa nsomba ndi amangoona mamita zosakwana 3.8. Koma msinkhu iwo anayamba akafika mamita awiri. Amuna, nthawi uyu akubwera ndi kutalika thupi la mamita 1,9.

Kamodzi mating kwachitika, mkazi angathe kutenga mimba nthawi yomweyo. Umuna maselo mthupi lake ukapitirize miyezi, kuyembekezera nthawi ovulation. Pambuyo akazi anali ukala dzira, iwo amayamba pa gestation, zomwe ukhoza kwa miyezi 9 chaka. Iwo ankakhulupirira kuti nsombazi buluu ndi pakati pa wakhama kwambiri wa anansi onse aakulu. Chiwerengero cha juveniles amene anabadwa, ndi osiyana, ndipo chiwerengero zimasiyanasiyana anthu 4 120. Kids amabadwa palokha, wokonzeka ndi zolusa moyo, koma theka la iwo ukufika kukhwima, chifukwa nsomba zikuluzikulu si mantha kuti apindule nawo.

limbikitsa nsomba

Koma njira ya nsomba kubalana opezeka osati nsombazo. Ena mitundu kunyezimira alinso viviparous, monga stingray. Kawirikawiri, akazi akubweretsa mwana amene kutalika - 35 masentimita. Pakuti moyo mwankhanza ndiziwunda komanso ndi kunyezimira manta, amene dzina lina - ziwanda nyanja. Izi nsomba zazikulu , nayenso, adzabala mwana yemwe anabadwa kale kufika mamita ndi kulemera kwake - 50 kg. Kuti ana abadwe, mayi akuwombera ngati mwana wanu, kuti wopindidwa mu mpukutu wina. Patalipatali yomweyo kufalitsa ake mapiko 'ndi amasambira wamkazi. Woyembekezera, nsomba kuonetsa mokwiya kuposa kale lonse komanso luso kusefukira bwato.

Monga makanda kukhala m'mimba?

Amadziwika kuti moyo mwankhanza nsomba kumabweretsa kale anapanga mwana, koma asayansi kwa zaka sakanakhoza kuchilingalira mmene kutenga mwachangu mu mimba ya mpweya, pokhapokha ali ndi nsengwa ndi umbilical chingwe. Koma chinsinsi anali kuthetsedwa mu 2008. asodzi Okinawan nsomba pakati panyanja mdierekezi anamusiya, ndipo asayansi kuphunzira. Pofuna kumvetsa bwino nthawi gestation nsomba izi, ofufuza pang'ono bwino ultrasound chipangizo, kenako anayamba kugwira ntchito mu madzi amchere. Kuzipenya mpaka yobereka kumene kunachitika miyezi zisanu ndi zitatu. Iye anabadwa wina Bakuman akazi. Wakhanda kulemedwa makilogalamu 50.

Popeza ichi nsomba yokhala ndi kuyang'aniridwa ndi nyengo yonse gestation, asayansi anatha kumasulira chinsinsi cha mmene chipatso amapuma. Pamene m'mimba, mwana amagwiritsa makutu ake ndi kupopa kudzera awo madzi amniotic. Kuchita izi, iye ndi wamkulu, chimatsegula ndi kutseka pakamwa. Madzi kuti ikagwa umadutsa njira yapadera, nufikira valavu kumbuyo mutu (ndi cheza osati kokha, komanso nsombazo). Akuluakulu pamene galimoto musati kutseka pakamwa pako mwakamodzi zosefera madzi ndi zomera. Young ili m'mimba, m'pofunika ntchito pakamwa monga mpope. Mu njira iyi, chipatso angakhale kupuma ndi chakudya.

Ubale wa makolo ndi mwachangu

Popeza Young yomweyo pambuyo okonzeka kutsogolera ufulu, iwo zambiri kutero. Ambiri a iwo salinso amadalira mayi ake. Ndi zina, ndi bwino kukhala kutali ndi makolo awo. Akuluakulu samasankha kusiyanitsa pakati pa mbewu zawo kudya, ndipo ngati iwo ali ndi njala, iwo akhoza kupindula ndi ana ake.

Mitundu ina ya moyo yokhala nsomba

Ife tafotokozeramu nsombazo ndi cheza ndi cartilaginous nsomba. Mwa nsomba Bony zambiri amene kubereka spawning. Koma pakati pawo mukhoza kukumana ndi moyo mwankhanza. Amenewa anafotokoza tsimatogaster. Mtundu uwu wa nsomba pa zinthu zina monga nsomba, ndipo pa malo ena amatikumbutsa carp. malo awo - ndi Pacific Ocean, mbali ya kumpoto.

Koma osati ndi moyo zobala nsomba imene mwachangu odyetsedwa mwachindunji kuchokera m'mimba mwa mayi. Mkazi akhoza zimaswa mazira m'mimba. The mwachangu kudya yolk lapansi. Pamene nthawi ifika kubereka, mazira anapanga mu mwachangu ndi mayi wayamba kuwaponya. Mwachitsanzo, njira imeneyi nsomba kuswana chibadidwe eelpout. Pobadwa, mwachangu kale anapanga. Pa nthawi wamkazi zingabweretse kwa nsomba mazana atatu, koma amapezeka mu magulu. Kukula kwa mwachangu wina wakhanda ndi masentimita anayi.

Mwa nsomba malonda viviparous ndi nyanja yoimba. Izi ndi mitundu wakhama kwambiri, zomwe lalikulu zedi amakodwa mu Barents Nyanja ndi Atlantic Ocean. Izi nsomba mwankhanza kwa chaka chimodzi amapereka ana a masauzande ambirimbiri. Chimakhala chiyambi mphutsi, omwe ali ofanana ndi asanu millimeters.

Yekha viviparous nsomba za m'nyanja ya Baikal

Baikal - ndi wokongola komanso chozama nyanja, ndipo kunyumba kwa anthu ambiri m'madzi. Pakati zosiyanasiyana mukhoza kukumana yekha viviparous nsomba otchedwa kansomba. Kwa ambiri, mfundo zingaoneke zodabwitsa, chifukwa kawirikawiri mu M'madera a zitunda wakumpoto wa nsomba ziberekane mwa spawning. golomyankas mitundu iwiri ndisefukira pano. Ambiri amakula masentimita 25, ang'ono si upambana 15 masentimita. Kansomba amachita spawning migrations, monga amachita ena onse a nsomba zimaswana. Pamene nthawi ifika, ndipo mu mimba ya ng'ombe yaikazi kwasanduka mwachangu, mayi limatuluka pafupi ndi pamwamba pa madzi. Ambiri mwina, m'pofunika kuonetsetsa kuti ana kudya zomera. Viviparous kansomba amapereka zinyalala lalikulu, malingana ndi mtundu wake. Pali chochepa nthawi, osati zambiri 1,5 zikwi. Fishies. Pa lalikulu, chithunzi ichi ndi 2.5 zikwi. Mwachangu. Atabadwa, mayi afa. Kodi sizodabwitsa kuti mtundu uwu wa nsomba imapezeka mu Baikal. Chotero limagwirira a kubadwa ndi imfa simudzapezeka abwerezedwa anthu ena m'madzi.

Aquarium okhala

Koma nsomba viviparous zimapezeka osati mwa nsomba malonda. Ambiri Aquarium eni mukudziwa kuti ena okondedwa awo mwachangu kuswa. Kwenikweni kubadwa moyo ndi chibadidwe poeciliidae banja, Gudieva ndi ena. Kawirikawiri nsomba sukulu, ndi ang'ono. Komanso mwa iwo ndi amuna pang'ono kakang'ono kuposa akazi, ndi mitundu yawo ngati m'tsogolo. Pamene iwo akhwime kugonana, chipsyepsye kumatako wa mwamuna amakhala gonopodium limene umuna zimachitika. Mtundu uliwonse amakhazikitsa mbali mwini chosiyana mu kapangidwe ka ndondomeko. Izi ndi zofunika kuti kuthetsa imabwera mwakusakaniza. Koma obereketsa chaka kawetedwe mitundu yatsopano ya nsomba yokongola, imbaenda ku maonekedwe a mitundu zachilendo ndipo mosiyanasiyana. Izi makamaka zikukhudza guppies. Popanda kuswana viviparous yokongola nsomba mofulumira wotaya mtundu wake ndipo pang'ono ndi pang'ono likunyonyotsoka.

mwachangu chitukuko

Nthawi ya chitukuko mazira ndi mwachangu mu mimba ya mkazi chimadalira pa banja ndi mtundu wa nsomba. Pambuyo umuna, gestation ukhoza mlungu umodzi kapena iwiri. Koma zina nsomba nthawi ino angathe miyezi 2.5. livebearers kwambiri poeciliidae mabanja achinyamata analandira lalikulu ndipo nthawi yomweyo zambiri mosavuta kuposa iye caviar, pamene mitundu ina mwachangu kulemera ndi wamkulu kuposa mazira ndi umuna. Ndipo chifukwa chakuti mkaka kwa mwamuna ndi mkazi akhoza kukhala mu nthaŵi yaitali, mazira akhoza ukala yomweyo, koma patapita nthawi, osati kamodzi. Choncho, ngakhale pamene limodzi ubwamuna nsomba amatha kubereka kangapo. Mulereni yosavuta wake, chifukwa mwachangu nthawi yomweyo pambuyo pa kubadwa zachangu. Chiwerengero cha juveniles zimadalira nsomba ndi angakhale mayunitsi ochepa ndi mazana.

Zamkatimu livebearers

Kuti moyo zobala nsomba kuswana bwino, m'pofunika kusamalira za zinthu zosiyanasiyana awo. Pakuti amanena zambiri abwino m'chere zokhala m'malo owetera ambiri, amene ali zomera m'nkhalango. Komanso, madzi ndale amafuna m'malo zonse. Mlungu uliwonse m'malo ndi 15 mpaka 40% madzi. Koma ena mitundu adzamvera kwambiri bwino kwambiri ngati madzi mchere. zinthu zimenezi makamaka kwa mollies ndi belonezoksov. Chifukwa chaichi, malita khumi ndi anawonjezera supuni ya nyanja mchere. Komanso yabwino madzi kutentha kwa mitundu yambiri zambiri Mitandadza 20 mpaka 25 ⁰ C.

Nsomba chakudya chinali moyenera, ayenera kuwonjezera zigawo zikuluzikulu masamba mu chakudya. Zimakhala saladi filamentous algae, oatmeal ndi zakudya zina.
