Dolphin wamaso oyera ndi woimira bwino mitundu ya Dolphin kuchokera ku Cetaceans ndi mtundu wa dolphin wamutu wamfupi. Mu ukapolo, monga lamulo, imvi nyama zakale zimasungidwa, koma nthawi zina zimakhala zotheka kukumana ndi zokongola zoyera-nkhope zomwe zimasiyanitsidwa ndi chikhalidwe cha anthu komanso malingaliro abwino.
Kufotokozera kwa dolphin wamaso oyera
Ma dolphin okhala ndi nkhope zoyera amakhala ndi thupi lolimba komanso lolimba.... Wokhalamo m'madzi wotere amakhala ndi chidwi ndi chidwi komanso chidwi, komanso kuyenda kwakukulu komanso kusewera.
Maonekedwe
Dolphin wamaso oyera ndi wokhala m'madzi ambiri. Kutalika kwakutali kwa nyama yayikulu ndi mita zitatu ndikulemera kwa thupi mpaka makilogalamu 350-355. Wokhala m'madzi otere amadziwika ndi mbali ndi gawo lakumtunda kuseri kwa dorsal fin kwa utoto wonyezimira. Mbali yakumunsi ya thupi ndi yoyera, ndipo mbali yakumaso kutsogolo kwa dorsal fin dera ili lakuda. Zipsepse zakumapazi ndi zipsepse za dolphin wamaso oyera ndi akuda.
Mlomo wam'madzi nthawi zambiri umakhala woyera, koma mwa anthu ena umakhala wa phulusa. Ma dolphin okhala ndi nkhope zoyera ali ndi mano 25-28 otukuka bwino komanso olimba mano pachibwano chilichonse. Oimira mitundu ya dolphin kuchokera ku Cetaceans ndi mtundu wa dolphin wamutu wamfupi amadziwika ndi kupezeka kwa ma vertebrae 92, omwe amapitilira kuchuluka kwa mapangidwe amtundu wina uliwonse wamtundu wa Delphinidae. Ma dolphin omwe amakhala ndi nkhope yoyera amatha kusambira, amakhala ndi liwiro losavuta mpaka 30 km / h ndipo nthawi ndi nthawi amalowera m'madzi akuya 40-45 mita kapena kupitilira apo.
Moyo, machitidwe
Ma dolphin okhala ndi nkhope zoyera amapezeka m'madzi ozizira, pafupi ndi gombe awiriawiri kapena pagulu logwirizana, loyimiridwa ndi anthu 10-12. Nthawi zina anthu osowa m'madzi oterewa amatha kuphatikiza m'magulu akulu, okhala ndi anthu mazana angapo.
Ndizosangalatsa!Mtundu wa dolphin wokhala ndi zoyera uli m'gulu la nyama zophunziridwa pang'ono, ndipo pakadali pano ndizosowa kwambiri m'chilengedwe chake.
Nthawi zambiri anamgumi okhala ndi nkhope zoyera nthawi zambiri amakhala ngati gulu la anthu ena pabanjapo, kuphatikizapo anangumi ndi anangumi. Madera akulu kwambiri amachitika chifukwa chakupezeka kwa nyama zambiri pamalo ena. M'madera omwe amadziwika ndi chakudya chochuluka, ma dolphin omwe ali ndi nkhope zoyera amatha kusonkhana m'magulu a anthu chikwi chimodzi ndi theka.
Kutalika kwa anamgumi okhala ndi nkhope zoyera amakhala
Nthawi yayitali yokhala ndi dolphin wokhala ndi nkhope yoyera m'chilengedwe imatha zaka makumi anayi. Ali mu ukapolo, wokhala m'madzi otere amakhala moyo wocheperako.
Zoyipa zakugonana
Dolphin yachikazi imakhala ndi khola limodzi la urogenital lotambasula kufanana ndi dera lamimba... Mulinso kutuluka kumatako. Clitoris yotukuka bwino, yoyimiriridwa ndi corpus cavernosum ndi nembanemba yakuda ya albinous, imayenda mkati mwa minofu yolumikizana yolimba yomwe ili kutsogolo kwa akazi. Ziwalo zoberekera zakunja za dolphin wamkazi ndi labia minora ndi majora.
Ndizosangalatsa! Tiyenera kudziwa kuti amuna amtundu wa dolphin oyera nkhope, monga mwachizolowezi, amakhala akulu kwambiri kuposa akazi kukula kwamthupi.
Maliseche amphongo amphongo amadziwika ndi kupezeka kwa perineum, komwe kumalekanitsa khola loberekera ndi kutuluka kumatako. Ma dolphin alibe mikwingwirima, ndipo pamimba pamakhala poyeserera. Potengera kutentha kwa thupi pa 37zaKuchokera pamadigiri, njira ya spermatogenesis imapitilira mwachizolowezi, ndipo kayendedwe kabwino ka kutentha kwa njirayi ndi 38zaKUCHOKERA.
Malo okhala, malo okhala
Nyama yam'madzi ya mammalian imakhala kumpoto kwa Atlantic kuchokera kunyanja yaku France mpaka Nyanja ya Barents. Komanso, malo achilengedwe a nthumwi za mtundu uwu wa dolphin kuchokera ku Cetaceans ndi mtundu wa dolphin wamutu wochepa amangokhala ku Labrador komanso m'madzi a Davis Strait, mpaka ku Massachusetts.
Malinga ndi zomwe akatswiri adaziwona, wokhalamo m'madzi uyu ndiwofala kwambiri m'madzi a Nyanja ya Norway komanso m'madzi a North Sea, okhala m'malo omwe ali m'mphepete mwa nyanja ya Great Britain ndi Norway. M'malo mwake gulu lalikulu la anamgumi okhala ndi milomo yoyera lalembedwa mu Varangerfjord. Anthu okhala m'malo ano amafikira mitu masauzande angapo pagulu lililonse.
M'nyengo yozizira, dolphin wokhala ndi milomo yoyera imakonda kusamukira kumadera akumwera kwa nkhondoyi, komwe kumakhala kotentha komanso kotentha. Ku Russia, nyama yotere imapezeka kulikonse pagombe lonse la Murmansk komanso pafupi ndi Peninsula ya Rybachy. Pali milandu yodziwika bwino ya anamgumi oyera okhala ndi milomo yoyera omwe amakhala ku Gulf of Finland ndi Riga, koma malo a nyama zam'madzi izi ndizosiyana. Anthu angapo amapezeka m'mphepete mwa nyanja yaku Sweden ku Baltic.
M'madzi a Davis Strait, ma dolphin okhala ndi zoyera amawonekera mchaka pamodzi ndi porpoises, narwhal ndi beluga whale atachoka mderali, zomwe zimawopseza nyama zosowa. Komabe, pofika Novembala, anthu okhala m'madzi akuyesera kusamuka mwachangu momwe angathere kumwera, komwe nyengo imakhala yabwino momwe angathere.
Zakudya zoyera za dolphin
Anapiye okhala ndi nkhope zoyera ndi nyama zolusa m'madzi. Oimira mitundu ya dolphin kuchokera ku Cetaceans ndi mtundu wa dolphin wamutu wochepa kwambiri amadyetsa makamaka nsomba, komanso nkhanu ndi nkhono.
Nzika zazikulu zam'madzi zotere zimapeza chakudya chawo chokha, chifukwa chake zakudya za nyama ndizosiyana.
Nyamayo imadyetsa cod, hering'i, capelin ndi nsomba zina... Ma dolphin sangakhale pachiwopsezo chilichonse kwa anthu. Komabe, pali milandu yodziwika bwino pomwe okhala m'madzi amabweretsa zovuta kwa anthu. Nyama zabwino kwambiri komanso zokongola modabwitsa zimakonda kusewera ndikusilira mwamisala. Akamasewera pansi pamadzi, ma dolphin amathamangitsa ndere zazikulu.
Ndizosangalatsa! Atatha kudya chakudya, dolphin wa milomo yoyera amagawika m'magulu ang'onoang'ono angapo, omwe amayenda mwachangu mbali zosiyanasiyana.
Mu nthawi yawo yaufulu posaka chakudya ndi kupumula, achikulire am'madzi amakonda kupusitsa ndikufulumira mpaka 35-40 km paola, komanso amalumpha pamadzi. Kutsimikiziridwa kwasayansi ndi phindu la ma ultrasound otulutsidwa ndi ma dolphin pa anthu. Chifukwa chosewera kwawo, chidwi chawo komanso chikhalidwe chawo, zinyama zotere zimagwiritsidwa ntchito mwakhama muma dolphinariums ndi m'mapaki amadzi.
Kubereka ndi ana
Nthawi yokhwima msinkhu ndi kubadwa kwa ana imagwera m'miyezi yotentha yokha yachilimwe. Nthawi yoti bere wamkazi wamkazi wa nkhope yoyera ndi pafupifupi miyezi khumi ndi chimodzi.
Kwa kanthawi atabadwa ana a dolphin, akazi omwe amakhala nawo amayesetsa kudzipatula kutali ndi mamembala ena am'banja. Zitenga zaka zisanu ndi ziwiri mpaka khumi ndi ziwiri kuti ana ang'onoang'ono ang'onoang'ono akule, kukhala olimba komanso kufikira msinkhu wogonana. Munthawi yonseyi, mkazi amaphunzitsa ana ake maluso ofunikira, kuphatikizapo kupeza chakudya komanso kukhala ndi moyo wathanzi m'malo ovuta.
Zinyama zodabwitsa komanso zolemekezeka zomwe zimakhala mumadzi, zomwe zimakhala zolemera kwambiri komanso zodziwika bwino, zimatha kuliza malikhweru ndi kufuula, kudina kosiyanasiyana, komanso mitundu ina yambiri yamaluso. Nzosadabwitsa kuti dolphin onse, kuphatikiza ndevu zoyera, amadziwika chifukwa cha msinkhu wawo. Nthawi zambiri nyama zotere sizimangothandiza anzawo amtundu wawo wokha, komanso anthu omwe ali pamavuto, osweka kapena kusowa madzi.
Adani achilengedwe
Gwero lalikulu la ngozi za dolphin amene nkhope zawo ndi zoyera ndi anthu, moyo wawo, komanso mpweya woipa wamafakitale m'madzi am'nyanja. Nyama yochezeka komanso yosangalala ilibe adani achilengedwe.
Malinga ndi kuyerekezera, kuchuluka kwa oimira mitundu iyi akufikira 100 zikwi. Zinyama zina zam'madzi zimafa zikalowa mu ukonde wosodza, koma chowopseza kwambiri moyo wa dolphin wokhala ndi nkhope yoyera ndi kuipitsa madzi ndi zinthu zoopsa za organochlorine ndi zitsulo zolemera. Anti-poaching amathanso kuonedwa ngati njira zodzitetezera.
Ndizosangalatsa!Ngakhale kuti nyamayi sindiye nsomba zamalonda komanso pamlingo waukulu, m'maiko ena, nyama zoterezi zimangogwidwa nthawi zonse ndi cholinga chogwiritsa ntchito pakampani yazakudya.
Ma dolphin okalamba nthawi zambiri amakumana ndi zovuta zazikulu za nsagwada. Monga lamulo, nyama zakale zoyamwitsa zimadwala matenda omwe amawonetsedwa ndi ma abscess a alveolar, mafupa exostoses ndi synostoses. Palinso tizirombo ta nematode tomwe timasokoneza thanzi lathunthu komanso chiyembekezo cha moyo wa ma dolphin.
Chiwerengero cha anthu komanso mtundu wa mitunduyi
Poganizira kuchuluka kwa nyama zazikuluzikulu padziko lonse lapansi, ndizotheka kunena kuti oimira mitundu iyi pakadali pano akhazikika. Dolphin wamaso oyera kuchokera ku Red Book ndi mtundu wosowa, wachilengedwe wachilengedwe womwe umafunikira chitetezo ndi njira zotetezera.
