Nyamayi ili ndi thupi lokulirapo, lopindika, lokutidwa ndi khungu lakuda mpaka 2-2.5 cm yokhala ndi khola. Mtundu wa dugong umakhala wonyezimira, ndipo kumbuyo kumakhala mdima kuposa mimba.
Kunja, ndi ofanana kwambiri ndi zisindikizo, koma mosiyana ndi iwo, sangathe kuyenda pamtunda, chifukwa, chifukwa cha kusinthika, miyendo yawo yakutsogolo yasandulika zipsepse, mpaka theka la mita, ndipo miyendo yakumbuyo kulibiretu.
Pamapeto pa thupi la dugong pamakhala mchira kumapeto, womwe umakumbukira za cetacean, ndiye kuti masamba ake awiri amasiyanitsidwa ndi notch yakuya, womwe ndi kusiyana zochita kuchokera manatee, woimira wina wa gulu la siren, yemwe mchira wake umafanana ndi chiwongolero.
Mutu wa ng'ombe yam'nyanja ndi yaying'ono, yosagwira, yopanda makutu komanso yamaso akuya. Pakamwa pake, pakamwa pake pamayenderera pansi, imathera mu mphuno yamachubu ndi mphuno zomwe zimatseka mavavu apansi pamadzi. Ma Dugong adamva bwino kwambiri, koma samawona bwino.
Khalidwe ndi moyo
Ma Dugong, ngakhale ndizinyama zam'madzi, amachita mosatetezeka kwambiri munyanja. Amakhala osakhazikika komanso odekha. Kuthamanga kwakanthawi kwamunthu m'madzi kumakhala pafupifupi makilomita khumi pa ola limodzi.
Kutengera ndi moyo wawo, safunika kuthamanga kwambiri, ma dugong ndi nyama zodyera, chifukwa kusaka sikupezeka mwa iwo, ndipo nthawi zambiri amasambira kunyanja, kupeza chakudya chofanana ndi ndere.
Nthawi ndi nthawi, nyama zamtunduwu zimasamukira kumalo ozizira am'madzi am'nyanja, momwe mumakhala chakudya chochuluka. Ma dugong nthawi zambiri amakhala okhaokha, koma nthawi zambiri amakhala m'magulu ang'onoang'ono a anthu asanu mpaka khumi m'malo omwe zomera zabwino zimasonkhana.
Nyama izi sizimawopa anthu, chifukwa chake pali zosiyana zambiri chithunzi cha dugong amapezeka mosavuta pa intaneti. Kutengera kukula kwake ndi khungu lakuda, samathanso mantha nyama zina zam'nyanja, zomwe sizimawaukira.
Izi zimachitika kuti nsombazi zimayesa kuwukira ana a dugong, koma amayi a mwanayo akangowonekera, asodziwo amasambira nthawi yomweyo.
Zowonjezera, chifukwa cha mawonekedwe amphamvu a nyamazi mzaka za 2000, mndandanda watsopano kwambiri wofika ku Russia ngalawa «Dugong"Pamlengalenga. Mabwatowa, monga nyama, ali ndi mphuno yakuthwa kutsogolo.
Chakudya cha Dugong
Ma dugong amadyetsa zomera zam'madzi zokha. Amachipeza pansi pa nyanja, ndikuchikokolola pansi ndi milomo yawo yayikulu yakumtunda. Chakudya cha tsiku ndi tsiku cha ng'ombe yam'nyanja ndi pafupifupi ma kilogalamu makumi anai a algae ndi udzu wam'nyanja.
Amuna achikulire amakhala ndi mano atali akutali okhala ngati mano, omwe amatha kuwazula mosavuta pansi pa chomeracho, ndikusiya mizere kumbuyo kwawo, yomwe ikuwonetsa kuti ng'ombe yam'nyanja imadyetsa m'malo ano.
Ma Dugong amathera nthawi yawo yambiri kufunafuna chakudya. Amakhala pansi pamadzi pansi pa nyanja mpaka mphindi khumi ndi zisanu, kenako amayandama pamwamba kuti atenge mpweya ndikumizanso pansi kusaka chakudya.
Nthawi zambiri, anthu amatolera ndere pamalo ena, motero amadzipezera chakudya chakutsogolo.
Nthawi zina pamakhala thupi lanyama, pamodzi ndi ndere, nsomba zazing'ono ndi nkhanu (nkhanu, nkhono, ndi zina zambiri).
Kubereka ndi chiyembekezo cha moyo
Kutha msinkhu zinyama dugong kufika pofika chaka chakhumi cha moyo. Palibe nyengo yobereketsa motero, imatha kukwatirana chaka chonse. M'nyengo yokwatirana, nthawi zambiri pamakhala kupikisana pakati pa amuna ndi akazi, zomwe zimawonetsedwa pankhondo zomwe amuna amagwiritsa ntchito mano awo mwanzeru kuti awononge mdani.
Pambuyo pa kupambana kwa imodzi yamwamuna, imachoka ndi mkaziyo kuti akatenge pathupi. Pambuyo pa umuna, ma dugong achimuna satenga nawo gawo pakulera ndi kuphunzitsa ana awo, kusambira kutali ndi akazi.
Mimba m'mayimbidwe azimayi amatha chaka chonse. Nthawi zambiri mwana m'modzi, nthawi zambiri samabadwa, omwe amalemera pafupifupi makilogalamu makumi anayi ndi kutalika kwa thupi mpaka mita. Ana obadwa kumene amadya mkaka wa mkazi, pokhala ndi iye nthawi zonse atakhala pamsana pa amayi.
Kuyambira mwezi wachitatu wamoyo, ma dugong achichepere amayamba kudya zomera, koma samasiya mkaka kwa chaka chimodzi ndi theka. Atakhwima, ma dugong achichepere amasiya kutsagana ndi akazi ndikuyamba kukhala moyo wawo.
Pafupifupi, kutalika kwa moyo wa zinyama izi kuli pafupifupi zaka makumi asanu ndi awiri, koma chifukwa cha kusaka nyama ndi anthu ochepa, ndi ochepa omwe amafika paukalamba.
Pazifukwa zosiyanasiyana, kuphatikiza chifukwa cha zochitika za anthu, m'zaka za zana la makumi awiri, anthu a dugong adatsika kwambiri. Mitundu yawo imaphatikizidwa ndi International Red Book ngati yotetezeka. Kutetezedwa ndi mabungwe apadziko lonse monga GreenPeace.
Kugwidwa kwa nyamazi kumaloledwa moperewera pogwiritsa ntchito masupuni komanso kwa anthu am'deralo omwe amadya nyama, mafuta pazithandizo zamankhwala, ndikupanga luso lokumbutsa mafupa. Gwirani ma dugong maukonde ndi oletsedwa.
