Ngati ali m'tulo otters nyanja? Nyanja otters: Chidwi Mfundo

The nyanja otter (nyanja otter) amakhala mabacteria otentha ndi kotentha ya Pacific gombe la America South. Ndi miyezo anatengedwa kuteteza nyama ndi chitetezo wawo wa kusaka izo ndipo akupitiriza lero. Iwo amapitiriza kuwononga chifukwa cha ubweya ndi zikopa, kuwonjezera, monga mpikisano kupanga nkhono ndi nsomba.

mafotokozedwe

Ndi otter laling'ono ku mtundu Lontra. Iwo ali cylindrical, wandiweyani, elongated thupi, miyendo lalifupi ndi amphamvu. ubweya wake ndi tsitsi olimba wandiweyani, ndi undercoat wa ku 12 mm, alonda tsitsi - 20 mm. Nyanja otters, amene chithunzi ali m'nkhani ino, podshestok louma ngakhale pamene kunyowetsa okha kale. No nkhokwe mafuta.

Mutu wa nyama ndi lathyathyathya chonse adzakhale anapereka otsika, makutu yaing'ono, yomwe ili m'mbali mwa mutu. Short lonse kuipanikiza ndi ndevu yaitali, wakuda, lalifupi khosi ndi mutu lonse. maso Small wozungulira anapereka mkulu, ndi aone kwambiri.

mchira wake phirilo zooneka, wakuda ndi akulu. zala zisanu ndi zikhadabu zakuthwa pa yoteroyo wolimba Ngati a Bakha. Pa nyanja otter miyendo kutsogolo wamfupi kusiyana kumbuyo. Makutu ndi mphuno anatseka pamene kumizidwa m'madzi.

mano Large kusinthidwa kwa kukhadzula nyama.

adani

adani awo chachikulu - izo orcas (wakupha zinsomba). nyama achinyamata komanso ankasakidwa ndi nsombazo, m'madzi ogwirira ndi mbalame.

chakudya

Nyanja otters ndi omnivorous, iwo kupeza chakudya mu zone iri yochepetsetsa-osefukira. zakudya zanyama lapangidwa ndi nkhanu, ngale, mbalame za m'madzi, nsomba ndi zamoyo zina zimene zimakhala mu nyanja. Nthawi zina amabwera mu mtsinje, kufunafuna madzi nkhanu. Pa kusasitsa zipatso wakudya zipatso za banja bromeliad mbewu.

khalidwe

Nyanja otters - ndi mobisa komanso amantha nyama, ndiwo diurnal (ngakhale otters nthawi zina achangu m'bandakucha ndi madzulo). Mu madzi, akupereka 70% ya moyo wawo, nthawi yomweyo chokambirana kupeza chakudya ndi kusaka. Kusambira, atagwira kumbuyo chapamwamba ndipo mutu.

nyama zawo nyama limagwira avareji mamita 300 kuchokera gombe, likumira kwa 30-50 m, pamene pamadzi mu chitsamba pafupi mathanthwe ndi Seaweed. Kumiza amatenga kwa masekondi 30. Mtundu wa miyala kuswa zipolopolo za nkhanu ntchito.

Ngakhale kuti otters nyanja makamaka nyama za m'madzi, iwo nthawi zina kupita ku gombe, kutali ndi 30 m, ngakhale kufunafuna nyama pita 500 m. Nyama pa dziko labwino kukwera miyala. Otemwa kupumula mwa zomera pa gombe, atagona pafupi ndi madzi.

Y akuimira khola Otter ndi burrow njira yotulukira komwe ya zotuluka mu m'nkhalango chidzenje. Pa nthawi imeneyo, ngati sakugwira kusaka, iye akupumula mu zomera wandiweyani. "Nyumba" ntchito za pobereka, kudyetsa ana, kugona ndi zina. Nyanja otters kwambiri amakonda kunama dzuwa, zomwe snuggles miyala. kamakumba una awo ndipo angakonze rookery kumene mungapeze chakudya mosavuta.

Monga otters kugona nyanja

M'chaka, pamene, kumene nyama amathera pafupifupi nthawi zonse mu madzi, njira amagona zikuwoneka amazipanga olimbikitsa. Young akugona pa chifuwa mayi ake, mokoma wokhudza chibwano ake, otters mutu, ndi wamkulu nyanja kusunga totsegulira pa wina ndi mzake. Ndithudi, izi ndi chikondi, ndi kufunikira - mpaka nyama akugona, kuti akhoza kukwaniritsa pa nyanja kutali kwambiri. Koma kodi chisoni zikuwoneka mapazi plexus!

Ngati nyama amapha yekha, ndi akagona kukonza semblance nangula. Otter yaitali akutembenukira ku Seaweed, kotero kuti chilonda pa thupi lanu, ndiyeno apita kukagona mwakachetechete izi choyambirira "chikhungwa".

zinthu zokhudza

Animal amatsogolera moyo yekha. Tikumbukenso kuti pafupifupi anthu kachulukidwe - mpaka otters 10 pa kilometre mwa nyanja. Nthawi nyama akupezeka magulu a anthu 2-3, koma osatinso. Kwenikweni iwo sangagone Chrixitu pa mtunda wa 200 m.

nyama zimenezi si dera lawo, iwo ali mwaukali aliyense kuti maonekedwe a anthu atsopano a mtundu wawo m'deralo. akazi angapo mosavuta azikhala pa pamalo omwewo, womwenso kusaka, mayenje, ndi zosangalatsa. Nthawi otters ndowe zaikidwa ndi mkodzo obisalamo ndi miyala, koma nthawi zambiri defecate kumene zina.

kubalana

Little amadziwika za iye, ndipo mfundo kuti sayansi ali koma kukhazikitsa akungokuonani osiyana anamasulira ambiguously. Kwenikweni, otters nyanja monogamous, koma malo awo ndi woipa lalikulu (chochuluka chuma chakudya), nthawi zambiri anaona ndi chitukuko cha ubale mitala. Pa mating ndi awiri kawirikawiri anati ndewu pakati pa amuna, komanso anaona kulimbana kwa mwamuna awiriawiri.

Maonekedwe a ana agalu kumachitika mu dzenje m'dzenje. A wamkazi awiriawiri 2 nsonga zamabele. Nthawi zambiri banja amasintha chitetezo pofunafuna malo abwino kwa chakudya, makolo mu nkhani iyi ndi kunditumiza ku mano wamng'ono kapena kusambira pa nsana wanu panyanja, powasunga pa mimba zawo.

chidzukulu

The wamkazi chibala 2 ana agalu (ndi zina 4-5). Kwa miyezi ingapo, anapitiriza yoyamwitsa. Youth ndi makolo ndi miyezi khumi. Mu ichi wamkulu m'badwo wamng'ono akubweretsa chakudya powaphunzitsa kusaka.

Ntchito munthu

Monga tanena kale m'nkhani ino, zaka zambiri anazunza otter nyanja chifukwa cha chikopa chake ndi ubweya, komanso chisoni monga mpikisano kupanga nkhono ndi nsomba. Nyama mu ali mwana, n'zosavuta kwambiri kuti kuŵetedwa, wophunzitsidwa ndi ntchito asodzi m'tsogolo.

anthu

Tikumbukenso kuti otters nyanja tapangidwa mu mapepala a Convention yatchula ndi mayiko Red Book, koma kufuna iwo likupitirirabe ngakhale lamulo anatengera mtundu wa chitetezo.
