Mawonekedwe ndi malo okhala
Sankhapo nsanza Ndi amtundu wa nsomba zopangidwa ndi ray, woimira singano, gulu ili ngati singano. Wonyamula nsanza, bwanji amatchedwa choncho kansomba kakang'ono aka? - zitha kuwoneka kuti funsolo ndi lomveka, koma pokhapokha mutamuwona - zophuka zambiri paphiri zimafanana ndi nsanza zazing'ono zomwe zimayandama m'madzi.
Kutalika kwa thupi kwa munthu wamkulu kumatha kufikira masentimita 35. Pali onyamula nsanza zamitundumitundu yosiyanasiyana yachikaso, koma njira zamdima zosasintha zimakhala zofala kwa onse. Ngati ndi kotheka, nsombayo ikhoza kusintha utoto wake.
Kusiyana kwakukulu pakati pa mitunduyi ndi mitundu ina yapanyanja ndi mawonekedwe ake osazolowereka. Thupi ndi mutu wa nsombazo zimaphimbidwa ndi mawonekedwe owala opanda mawonekedwe omwe amafanana ndi udzu wam'madzi. Hatchiyo imawoneka yokongola kwambiri, koma safuna njira izi kuti zikhale zokongola - zimadzibisa.
Chifukwa chake, chifukwa cha mawonekedwe achilengedwe amtundu wonyamula nsanza, ndizosatheka kuwona pakati pa ndere zazikulu. Izi zimamuthandiza kuti akhalebe ndi moyo mdani akamayandikira, komanso kumathandizira kwambiri kusaka kwake.
Tiyenera kudziwa kuti ma skate sanaphatikizidwe pakudya kosalekeza kwa nsomba zina zodyera (kupatula ma stingray), popeza thupi lawo silikhala ndi michere - kukhala pansi sikutanthauza kuti azikhala ndi minofu, komanso, mwa wamkulu pafupifupi 2 mafupa ochulukirapo kuposa nsomba zina.
Kapangidwe ka thupi la ragman ofanana ndi ma seahorses ena - pakamwa amafanana ndi chubu chachitali chotalika, mutu wawung'ono umalumikizidwa ndi thupi lokhalitsa ndi khosi, maso awiri ang'onoang'ono koma okongola amatha kusiyanasiyana pamutu, omwe amayenda mosadukizana.
Mutha kukumana ndi nsomba m'madzi a Indian Ocean, kutsuka Australia ndi Tasmania. Makamaka Wopusa amakhala m'miyala yamiyala yakuya mpaka 4 mpaka 20 (osachepera 30) mita, amakonda kutentha pang'ono komanso algae wandiweyani.
Mitunduyi ili m'manja mwa boma la Australia, chifukwa ili pangozi. Izi zomvetsa chisoni zimachitika chifukwa cha kuchuluka kwa mpweya wopangidwa ndi mafakitale m'madzi a Indian Ocean, komanso kulowererapo kwa anthu m'moyo wa nsomba.
Tsoka ilo, ndizosatheka kukana kukongola kwa onyamula masanza, ndipo anthu ochita masewera olimbitsa thupi nthawi zambiri amapita maulendo apansi pamadzi kuti akagwire nsomba zochepa zanyumba yam'madzi, ngakhale izi ndizovomerezeka ndi lamulo.
Khalidwe ndi moyo
Zikuwoneka kuti, chifukwa cha kuchuluka kwa zipsepse zonga zipsepse, nsombazo zimayenera kuyenda mwachangu kwambiri, komabe, pakuyenda, njirazi sizigwira ntchito iliyonse.
Zimayandama kavalo-kavalo mothandizidwa ndi peyala imodzi yokha ndi dorsal fin. Ntchitoyi imachitika modzidzimutsa (pafupifupi ka 10 pamphindikati) ndikugwedeza zipsepse zowonekera, zomwe zimawoneka kuti zimanyamula nsomba kumunsi. M'boma lino, ndikosavuta kuzilakwitsa chifukwa cha algae ang'onoang'ono oyandama.
Chombocho chimakhala ndi malo owongoka, popeza thovu limadutsa thupi lonse kumutu, komwe kuli kwambiri. Kuthamanga kwakukulu kwa munthu wamkulu ndi mamita 150 pamphindi, nsomba zimatha kuzisunga kwa nthawi yayitali, potero zimatha kutalikirana kwambiri.
Zachidziwikire, liwiro ili silokwanira kuti tithawe kuchokera kwa mdaniyo, chifukwa chake chitetezo chokhacho munkhokwe yosankhira zigawenga ndichobisalira. Ndizodziwikanso kuti skate imatha kusungabe malo ndi nyumba zonse kuti zibisike kwa nthawi yayitali (mpaka maola 68), njira zake zokha ndizoyenda nthawi ndi kayendedwe ka madzi, ndikulimbikitsa kuti ndi alga.
Chomwe chimasiyanitsa mahatchi onse ndi mchira wawo, womwe amatha kutengera ndere pakagwa madzi oyipa kapena namondwe, komabe, mtundu uwu ulibe luso loterolo, chifukwa chake otola nsanza nthawi zambiri amanyamulidwa kupita kumtunda, chifukwa chake amafa ambiri.
Chakudya
Ngakhale kukongola kwakunja ndi kusalimba, chilombo nyemba chilombo weniweni kwambiri. Monga nsomba yaying'ono, kavalo amakakamizidwa kufunafuna chakudya chaching'ono kwambiri. Monga lamulo, wosankhira amadyetsa zazing'ono zazing'ono, plankton ndi mitundu ingapo ya ndere.
Kuphatikiza apo, kuchuluka kwa chakudya chomwe chimadyedwa tsiku ndi tsiku ndichopatsa chidwi - ndikasaka kopambana, kavalo amatha kumeza shrimp shrimp 3000. Kudya komweko sikophweka - siketiyi imangoyimeza nyamayo yonse, chifukwa chakusowa kwa mano kapena mbale zam'kamwa kuti mumve.
Chakudyacho chimafika pammero, njira yosefera imachitika, chifukwa chake, madzi omwe amameza limodzi ndi nyamayo amatuluka kudzera m'mitsempha, ndipo chakudya chomwecho chimamezedwa ndi nsomba. Kusaka kumatha kuchitika patali - zokutira za gill zimapanga chidwi, chothandizidwa ndi phirilo kuchokera kumtunda wa 4 cm.
Kubereka ndi chiyembekezo cha moyo
Nthawi yokhwima imayamba koyambirira kwa chilimwe ndi magule ovuta a anzanu amtsogolo. Monga mitundu ina yama skate, mwamuna chiguduli nyanja imathandiza kwambiri pobereka, ndipo izi zilibe kanthu kuti ilibe thumba la dzira, pomwe nthawi zambiri mazira amaikidwa ndi mkazi kuti amere.
Mkaziyo amaikira mazira ofiira pafupifupi 120, omwe amapezeka pamalo apadera pafupi ndi mchira wamphongo. Njira yoberekera imachitika pamenepo ndipo mazira amakhala mthupi la abambo kwa milungu ina 4-8, mpaka makanda awonekere.
Pakati pa mimba yonse, wamkazi ndi wamwamuna amakhala pafupi, nthawi ndi nthawi akukonzekera kuvina kotsalira, panthawi yomwe khungu la anthu onse limakhala lowala kuposa masiku onse.
Anawo akangobadwa, nthawi yomweyo amakhala ndi moyo wodziyimira pawokha, wotsalira kwa iwo okha, makolo satenga nawo mbali pakulera. Tsoka ilo, ndi 5% yokha mwa zolengedwa zachilendozi zomwe zimapulumuka mpaka kukula ndipo zimatha kupanga m'badwo wotsatira. M'mikhalidwe yabwino kuthengo, kavalo Munthu wopanda pake amakhala pafupifupi zaka 5.
