I-Las ama-focas wakhe izilwane ezincelisayo ezihlala emanzini ezijwayele ukuhlala isikhathi eside emanzini futhi zingakwazi futhi kube ku umhlabathi. Izimvu zamanzi zifakiwe ngokulandelana kwezilwane ezidla inyama.
Izici zezimpawu
izimpawu wakhe izilwane ezihlala emanzini ashintshashintshashintshayo ezinezici eziningi ezizichazayo, esingazibala kanje:
- Ziyizilwane ezazo ukwakheka komzimba wazo ziyagobeka futhi zinde, kubalulekile ukuze zikwazi ukucwiliswa emanzini futhi zibhukude ngaphansi kwamanzi ngokushesha.
- Zinezitho ezine zangemuva eziqinile ezimiswe emuva, eziyisicaba, ezimfishane ngesimo samaphiko. Ziwusizo kakhulu ekubhukudeni, kodwa azisebenzi kakhulu uma ziphuma emanzini, nakuba kunezinhlobo zezimvu zamanzi ezikwazi ukuhamba kahle emhlabathini.
- Lezi zilwane ekukhuleni kwazo zikhona a uboya kufushane futhi kuvame ukuminyene. Kunezinhlobo zezimvu zamanzi ezingenazo uboya, lokhu kuyahlukahluka endaweni ezitholakala kuyo. Uboya balesi silwane akusikhona ukubavikela emazingeni okushisa aphansi njengakwezinye izilwane, okusivikela ngempela emakhazeni ukuvikelwa okushisayo okunikezwa ungqimba oluqinile lwamafutha atholakala ngaphansi isikhumba, imele up un okwesine i-del i-peso yophawu
- Lezi zilwane azinazo izindlebe kodwa akusho ukuthi azinazo izindlebe, kunalokho zinezwi elihle kakhulu futhi elibucayi kokubili emoyeni nasemanzini.
- Lapho zitshuza, lezi zilwane zivala izindlebe nekhala ukuze amanzi angangeni kuzo.
- Ikhanda lincane futhi liyisicaba, izinwele zamadevu ezinde zisiza ekutholeni isisulu futhi ziziqondise emanzini.
- Izinzipho zamaphiko angaphambili ziwavumela ukuthi abambe izinto, amadwala futhi azivumele ukuthi zibambe izingqimba zeqhwa zineminwe emihlanu elinganayo, kuyilapho emaphikweni angemuva iziphetho ziqine kakhulu.
- Imisindo ekhishwa ama-seal ibizwa ngokuthi ama-snorts, ukuphefumula kwawo kujulile futhi kunamandla.
Izinhlobo Zezimpawu
Kunezinhlobo ezingamashumi amathathu nantathu zezinhlobo zamanzi ezikhonjwa emhlabeni manje, esingabala ezimbalwa zazo:
- ingwe seal: Isibili ngobukhulu.
- I-Harp Seals: izinhlobo eziningi kakhulu zihlala e-Arctic naseNyakatho ye-Atlantic.

- I-Mediterranean Seal: Zibonakala ngokuba nophawu lwewashi kuzo.
Zidlani futhi ziziphatha kanjani?
Izimvu zamanzi azilokothi zisuke ogwini ngoba ukudla kwazo kumanzi futhi ulwandle yisiphephelo sazo, zidla ikakhulukazi ama-mollusc, octopus, crustaceans kanye nezinhlanzi. Njengoba ubona, ukudla kwazo kuyahlukahluka, futhi lokhu kunqunywa indawo ezihlala kuzo kanye nezinhlobo eziyizilwane ezidla inyama ezidla izinhlobo eziningi zezinhlanzi.
Zicwila emanzini zisebenzisa amaphiko azo, futhi njengoba sishilo ngaphambili, amadevu nezindlebe zazo ezizwelayo zisetshenziselwa ukubamba ukudla kwazo, zifake amazinyo azo amakhulu kuwo futhi zigwinye ukudla kwazo ngokuluma kanye, njengazo zonke izilwane ezidinga amanzi kodwa izimvu zamanzi. Bayithola ekudleni futhi ngaleyo ndlela bagweme ukuphuza amanzi anosawoti.
Zihlala Kuphi Izimvu Zamanzi?
Iningi lezimvu zamanzi lihlala olwandle ezindaweni ezibandayo nezipholile ezifana ne-Antarctica yizindawo ezivame kakhulu, zingachitha isikhathi eside oLwandle Oluphakeme, kufanele kuqashelwe ukuthi izimvu zamanzi nazo zingatholakala ogwini olushisayo, kodwa hhayi kakhulu. njalo njengoba bengebona abangani bokushisa. Lezi zilwane zingamelana futhi ziphile emazingeni okushisa aphansi kakhulu, nakuba lokhu kuhlukahluka kuye ngezinhlobo.
Izimvu zamanzi ezihlala ezindaweni ezishisayo azinawo ungqimba lwamafutha futhi mancane, ngokungafani nalezo ezihlala ezindaweni ezibandayo ezinogqinsi lwamafutha futhi zikhudlwana.
Uphawu oluphuma emanzini
Ziba yizilwane ezixakile zihamba kancane emhlabathini. Azikwazi ukuhamba ngamapheshana azo angemuva ngoba zihlehlile ngakho ziyaphoqeleka ukuthi zinyakaze sengathi ziyakhasa ngokusekela amaphiko azo angaphambili futhi zikhasa ngezisu ngokuphusha noma ukugxuma okuncane.
Ungathola inqwaba yezimvu zamanzi ezibuthene ogwini, ziminyene ukuze zikhuphule izinga lokushisa lomzimba wazo, ziphuca izinwele, zidlale, zilale futhi zishade, umhlambi ubonakala njalo uhamba ndawonye kuzo zonke ugu futhi bahlanganyela insimu namaphengwini. nezinye izilwane ezihlala emanzini, emadwaleni zihamba kalula futhi zingenye yezindawo ezizithandayo.
ukuphila phakathi kwezinguzunga zeqhwa
Izimpawu zezindawo ezinamazinga okushisa aphansi, zichitha cishe sonke isikhathi ngaphansi kweqhwa zifuna ukudla, amashidi awo eqhwa angaphezu kwemitha eyi-1, eklebhula iqhwa ngamazinyo, agcina imbobo encane yokuphuma ukuphefumula yonke into. isikhathi esithile.
Benza umgodi ube mncane ukuze ibhere elimhlophe lingawutholi kwazise liyisitha esikhulu sezimvu zamanzi, ibhere liyalinda lapho izimvu zamanzi ziphuma ukuze liphefumule, liwahlasele futhi liwadle. Ngaphansi kwamanzi le ndawo ivikelwe abesilisa bepaki.
ukukhwelana nokukhiqiza
Ukukhiqizwa kwezimvu zamanzi kwenzeka ngoMeyi noJuni, abesilisa balwela ukubusa indawo ogwini. Bese bephoqelela insikazi endaweni yabo kanye nomlingani wabo, ngisho namaduna angadla angadli ukuze enye iduna ingahlangani nensikazi endaweni yayo.
Ngemva kwezimpi eziqhubekayo, abavelele kuyoba yilabo abayoba nelungelo lokushada.. Umkhuba wokukhwelana uwukugingqika ogwini phakathi kwazo lapho kukhishwa amahomoni aheha insikazi, abeke ikhala lawo entanyeni yomunye bese kwenzeka isenzo. Insikazi ikhiqiza iqanda elivikelwe yisibeletho lapho likhiqiza khona amahomoni amaningi, iligcina esibelethweni sayo izinyanga eziyi-9 kuya kweziyi-11.
Ezinsikazi minyaka yonke zikhwelana endaweni efanayo, zizala ingane eyodwa. Uma benamawele, balahla ingane eyodwa ukuze banakekele omunye kangcono, emasontweni amane nje kuphela inzalo isuke yodwa. Yizona kuphela izilwane ezincelisayo ezidla isikhathi esincane ngobisi lwebele, zincela kuphela phakathi kwezinsuku eziyishumi neshumi nane.
Usongo lwakho olukhulu
Isikhumba se-seal saziswa kakhulu. Kukhona nezindawo lapho bedla khona inyama yabo bese bekhipha uwoyela wabo. Ukuzingela izimvu zamanzi nokudoba yizinsongo eziyinhloko kulesi silwane.
Emhlabeni
Kukhona njalo amaqembu amakhulu atholakala ogwini, okuwukuphela kwesilwane esiwahlasela emhlabeni ibhere elimhlophe, lokhu lapho lilambile kakhulu futhi njengazo zonke izilwane zasendle lizowahlasela ngokuzenzakalelayo ukuze lizondle ngokwalo.
Emanzini
Uma besatshiswa emhlabeni bayabaleka bayokhosela emanzini lapho bezizwa bephephile khona. Kodwa njengehlengethwa, ngezinye izikhathi izimvu zamanzi zigcina zingene emanetheni abekwe izikebhe zokudoba. Njengoba nje emhlabeni ibhere elimhlophe liyisilwane esizingelayo esiyinhloko, singabuye sibone endaweni Izimpawu Zoshaka, ukuthi uphawu luzingelwa yibo kanye nemikhomo.
Izimvu zamanzi ezisengozini
Empeleni, umuntu uyimbangela yokushabalala kwalolu hlobo lwezilwane, njengezinye izinhlobo zezilwane zasemhlabeni nezihlala emanzini emhlabeni. Baphethe ngokubalimaza, ukubabulala ngenxa yokuhweba kwabo ngesikhumba, ukucekela phansi indawo abahlala kuyo, ukubashiya bengenakudla, phakathi kokunye.
Kwesinye isikhathi bayazingelwa ukuze bawathande futhi bawasebenzise emibukisweni yase-aquarium, njengoba kwenzeka ngamahlengethwa. Kufanele uqaphele kancane ukuthi yonke into iyiketango futhi ukushabalala kwezimvu zamanzi kungase kubangele ukushabalala kwezinhlobo ezidla kuzo.
