Izici nendawo okuhlala kuyo uphawu
Uphawu lwezilwane etholakala ezilwandle ezigelezela olwandle i-Arctic, igcina ikakhulukazi eduze nogu, kepha ichitha isikhathi esiningi emanzini.
Kuyisiko ukubiza abameleli bamaqembu wezimpawu zezimpawu ezivulekile nezangempela. Kuzona zozimbili izimo, izitho zezilwane zigcina ngamaphiko ezinamazipho amakhulu akhule kahle. Ubukhulu besilwane esincelisayo sincike ekubeni sasohlobo luni oluthile kanye nezinhlobo ezithile zaso. Ngokwesilinganiso, ubude bomzimba buhluka kusuka ku-1 kuye ku-6 m, isisindo - kusuka ku-100 kg kuye kumathani we-3.5.
Umzimba oyindilinga ufana nophiko lokuphotha, inhloko incane ngaphambili, intamo ejiyile enganyakazi, isilwane sinamazinyo angama-26-36.
Ama-auricles awekho - esikhundleni sawo, ama-valve atholakala ekhanda avikela izindlebe ekungeneni kwamanzi, ama-valve afanayo atholakala emakhaleni ezincelisayo. On the isifonyo endaweni ekhaleni kukhona intshebe eside mobile - vibrissae ethintekayo.
Lapho uhamba emhlabeni, amaphiko angemuva ayadonswa emuva, awanakuguquguquka futhi awakwazi ukusekela. Amafutha angaphansi kwesilwane esidala angaba ngu-25% wesisindo somzimba esiphelele.
Ngokuya ngohlobo, ubukhulu bezinwele buyahluka, ngakho-ke, zasolwandle izindlovu - izimpawu, cishe abangenayo, kuyilapho ezinye izinhlobo ziziqhayisa ngoboya obukhulu.
Umbala nawo uyahlukahluka - kusuka konsundu ngokubomvu kuya ku uphawu olumpunga, kusuka ethafeni kuye emigqeni futhi uphawu olunamabala... Iqiniso elithandekayo ukuthi izimvu zamanzi zingakhala, yize zingenazo izindlala eziyizigaxa. Ezinye izinhlobo zinomsila omncane ongadlali ndawo ekunyakazeni emhlabeni nasemanzini.
Uhlobo nendlela yokuphila kophawu
Uphawu vula isithombe kubonakala sengathi yisilwane esiwubudlabha nesivilaphayo, kepha umbono onjalo ungakhula kuphela uma usemhlabeni, lapho ukunyakaza kuqukethe ukunyakaza komzimba okungenangqondo ukusuka kolunye uhlangothi kuya kolunye.
Uphawu olunamabala
Uma kunesidingo, isilwane esincelisayo singafinyelela isivinini esifinyelela ku-25 km / h emanzini. Ngokuya ngokuntywila, abamele ezinye izinhlobo nabo bangabompetha - ukujula kokuntywila kungaba ngamamitha angama-600.
Ngaphezu kwalokho, uphawu lungahlala ngaphansi kwamanzi cishe imizuzu eyi-10 ngaphandle kokuthutheleka komoya-mpilo, ngenxa yokuthi kunesikhwama somoya ohlangothini olungaphansi kwesikhumba, isilwane esigcina ngaso umoya-mpilo.
Ukubhukuda kuthungathwa kokudla ngaphansi kweqhwa elikhulu, izimvu zamanzi ezinekhono lithola ama-broods kuzo ukuze zigcwalise lesi sitoko. Kulesi simo uphawu lwenza umsindo, okufana nokuchofoza, okubhekwa njengohlobo lokufunda ngokufunda okuthile.
Lalela izwi lezimpawu
Ngaphansi kwamanzi, uphawu lungenza neminye imisindo. Isibonelo, uphawu lwendlovu lufaka isikhwama semakhaleni ukuze kuveze umsindo ofana nokubhonga kwendlovu ejwayelekile yomhlaba. Lokhu kumsiza ukuxosha izimbangi nezitha.
Abamele bazo zonke izinhlobo zezimpawu bachitha iningi lempilo yabo olwandle. Akhethwe emhlabathini kuphela ngesikhathi se-molt nokukhiqiza kabusha.
Kuyamangaza ukuthi izilwane zize zilale emanzini, ngaphezu kwalokho, zingakwenza ngezindlela ezimbili: ukujika ngomhlane, uphawu luhlala ebusweni ngenxa yongqimba lwamafutha nokuhamba kancane kwamaphiko, noma, lapho zilele, isilwane sicwila ngokujulile ngaphansi kwamanzi (amamitha ambalwa), ngemuva kwalokho iyavela, iphefumula kancane iphinde iphonse, iphinda le minyakazo kuso sonke isikhathi sokulala.
Ngaphandle kokuhamba ngezinga elithile, kuzo zombili lezi zimo isilwane silele ubuthongo. Abantu abasanda kuzalwa bachitha kuphela amasonto okuqala ama-2-3 emhlabathini, ngakho-ke, bengazi ngempela ukuthi bangabhukuda kanjani, behlela emanzini ukuqala impilo ezimele.
Uphawu lungalala emanzini, luginqike ngomhlane
Umuntu omdala unamabala amathathu ezinhlangothini, ungqimba lwamafutha okuncanyana kulo kunasemzimbeni wonke. Ngosizo lwalezi zindawo, uphawu luyasindiswa ekushiseni okukhulu, lunikeze ukushisa okweqile ngabo.
Abantu abasha okwamanje abanalo leli khono. Banikeza ukushisa kuwo wonke umzimba, ngakho-ke, lapho uphawu oluncane lulele eqhweni isikhathi eside lunganyakazi, kwakhiwa udaka olukhulu ngaphansi kwalo.
Kwesinye isikhathi lokhu kungabulala, ngoba lapho iqhwa lincibilika ngokujulile ngaphansi kophawu, lapho-ke alikwazi ukuphuma lapho. Kulokhu, ngisho nonina wengane akakwazi ukumsiza.Izimpawu zeBaikal bahlala emanzini avaliwe, okungeyona enye into ephilayo.
Ukuqinisa uphawu
Ukudla okuyinhloko komndeni wezinhlanzi izinhlanzi. Isilwane asinakho okuthandayo - luhlobo luni lwezinhlanzi esihlangana nazo ngesikhathi sokuzingela, sizoyibamba leyo.
Vele, ukugcina isisindo esikhulu kangako, isilwane sidinga ukuzingela izinhlanzi ezinkulu, ikakhulukazi uma sitholakala ngobuningi. Ngezikhathi lapho izikole zezinhlanzi zingasondeli emabhange ngosayizi odingekayo wophawu, isilwane singalandela inyamazane, sikhuphuke imifula.
Ngakho-ke, isihlobo se-larga yesimpawu ekuqaleni kwehlobo londla izinhlanzi ezehlela ezilwandle ezingasemifuleni yemifula, bese lishintshela kwi-capelin, ebhukuda iya ngasogwini ukuze izale. I-Herring ne-salmon yizisulu ezilandelayo minyaka yonke.
Lokho ukuthi, ngesikhathi esifudumele, isilwane sidla izinhlanzi eziningi, zona ngokwazo ezilwela ogwini ngasizathu sinye noma esinye, izinto ziba nzima kakhulu ngenkathi ebandayo.
Izihlobo ze-Seal zidinga ukusuka kude nogu, zihlala eduze nokukhukhuleka kweqhwa futhi zidle ama-pollock, ama-molluscs nama-octopus. Vele, uma kukhona enye inhlanzi evela endleleni yophawu ngesikhathi sokuzingela, ngeke ibhukude.
Ukuzala nobude bempilo yophawu
Kungakhathaleki ukuthi hlobo luni lolo hlobo, izimpawu zikhiqiza inzalo kanye kuphela ngonyaka. Lokhu kuvame ukwenzeka ekupheleni kwehlobo. Izilwane ezincelisayo zibuthana ezindaweni ezinkulu zokuvala uphawu eqhweni (ezwekazini noma, kaningi, i-ice floe ekhukhulekayo).
I-rookery ngayinye enjalo ingabala izinkulungwane ezimbalwa zabantu. Iningi labashadikazi lingabodadewabo, nokho, uphawu lwendlovu (olunye lwezimpawu ezinkulu) ubuhlobo besithembu.
Ukukhwelana kwenzeka ngoJanuwari, ngemuva kwalokho umama uzala izinyanga eziyi-9-11 izingane uphawu... Umntwana ngokushesha nje emva kokuzalwa angaba nesisindo esingama-20 noma ngisho ama-30 kg ngobude bomzimba wemitha eli-1.
Eved uphawu cub
Okokuqala, umama wondla ingane ngobisi, owesifazane ngamunye unamabhangqa ama-1 noma ama-2 wezingono. Ngenxa yokuncelisa, izimvu zamanzi zisinda ngokushesha okukhulu - nsuku zonke zingaba nesisindo esingafika ku-4 kg. Uboya bezingane buthambile futhi kaningi bumhlophe, noma kunjalo uphawu olumhlophe ithola umbala wayo wesikhathi esizayo unomphela emavikini angu-2-3.
Lapho nje isikhathi sokuncelisa ubisi sidlula, okungukuthi, ngemuva kwenyanga ngemuva kokuzalwa (kuya ngohlobo, kusuka ezinsukwini ezinhlanu kuya kwezingama-30), izingane ziyehlela emanzini bese zinakekela ukudla kwazo. Kodwa-ke, ekuqaleni bafunda nje ukuzingela, ngakho-ke baphila besuka emlonyeni beya emlonyeni, begcina kuphela ekunikezelweni kwamafutha atholakala obisini lukamama.
Omama abancelisayo bezinhlobo ezahlukene baziphatha ngendlela ehlukile. Ngakho-ke, izimpawu ezinamaconsi amaningi zihlala eduze ne-rookery, nabesifazane izimpawu zehabhuNjengezinye izinhlobo eziningi zezinto eziphilayo, zisuka ogwini ibanga elide ziyofuna izinhlanzi eziningi kakhulu.
Owesifazane osemncane ukulungele ukuqhubeka nohlobo eneminyaka engu-3; abesilisa bafinyelela ekuvuthweni ngokocansi ngeminyaka eyisithupha kuphela. Isikhathi sokuphila komuntu ophilile sincike kohlobo nocansi. Ngokwesilinganiso, abesifazane bangafika eminyakeni yobudala engama-35, abesilisa - 25.
