Namuhla siza neposi ehlukile kunaleyo esiyijwayele, emayelana nezinhlanzi. Ake sixoxe ngakho ulwandle otter. Lesi silwane yisilwane esincelisayo esinegama lesayensi I-Emhydra lutris futhi kuyaziwa emhlabeni wonke. Ngeyomndeni we-mustelidae futhi ihlala ezilwandle. Kulokhu okuthunyelwe uzokwazi ukwazi zonke izici, ukondla nokukhiqiza kabusha kwalesi silwane.
Ngabe ufuna ukufunda kabanzi nge-otter yasolwandle? Qhubeka ufunde.
Izici eziyinhloko
I-otter yasolwandle ingenye yezilwane ezincelisayo ezisikiwe kakhulu lapho ngenxa yobuncane bayo noboya bayo. Amehlo abo amancane abenza babonakale sengathi babukeka ngobuso obungenacala obugcwalisa bonke ababuka ngabo ngokudumisa. Abesilisa bakhulu kunabesifazane, yize benakho ubude obungamamitha ayi-1,2 kuye ku-1,5. Ngokuvamile anesisindo esiphakathi kwama-22 no-45 kilograms, yize abesifazane besisindo esincane kakhulu (cishe phakathi kuka-14 no-33 kilograms).
Amathambo ayo aguquguquka kalula ngakho-ke angathatha ukuma okuhle kakhulu. Imilenze yaso iyisicaba ukuze ikwazi ukubhukuda kahle futhi yakhiwe njengomphetho. Izinzipho ziyefana nezekati, ezisiza imisebenzi ethile njengokuzilungisa nokubamba kangcono isisulu sazo. Umsila unemisipha impela futhi ngokuyinhloko bayayidinga ukuqondisa inkomba ebhukuda ngayo. Kubasiza futhi ukugcina ibhalansi yabo kahle.
Abantu abadala banamazinyo angama-32 anezinsalela ezicijile neziyindilinga ezilungiselelwe ukugaya kunokuba zisike. Njengesici esikhethekile esisiza ukuthi, ngokwe-morphologically, sehlukanise i-otter kwezinye izidlo ezidla inyama ukuthi inezinsimbi ezimbili eziphansi kunezintathu.
Ngokuqondene noboya baso, isikhumba asinkulu kangako njengoba kwenzeka kwezinye izilwane ezincelisayo zasolwandle. Isikhumba esijiyile sisebenza ukuvimbela ukubanda kwamanzi futhi sikwazi ukulawula ukushisa kwangaphakathi kahle ngaphandle kwemvelo yangaphandle iphazamise kakhulu. Ngokungafani nabo, i- otter yasolwandle incike eboyeni bayo ukuze izivikele emazingeni okushisa abandayo. Futhi ukuthi banezinwele ezingaphezu kwezingu-150.000 ngosayizi omncane kangako ukuthi bahlala kuzo. Bangene irekhodi lesilwane esincelisayo esinezinwele eziningi.
Izintshisekelo ezikhethekile ze-otter yasolwandle
Ezinye izici zenza lesi silwane sikhetheke kakhulu. Eziningi zalezi zici ukuguquguquka kokuziphendukela kwemvelo okuhlobene nokwenza ngcono ukunyakaza kwayo emanzini. Ukusetshenziswa okuyinhloko ukuthuthukisa izinzwa zakho futhi uqaphele ukuzivikela ezingozini futhi uphile ngokunethezeka okuthe xaxa.
Nazi ezinye zalezo zici:
- Unamandla okwenza ukwazi ukuvala amakhala kanye nemisele yezindlebe emanzini ukugwema ukukungenisa emzimbeni wakho. Ngale ndlela, ususa ezinye zezinkinga ezihlobene nayo.
- Umunwe wesihlanu wesitho ngasinye mude ukudlula konke okunye. Leli qiniso linenzuzo nobubi ngokuya ngemvelo lapho ukhona. Ngakolunye uhlangothi, kuyasiza ukubhukuda kangcono uma usemanzini, kepha ngakolunye uhlangothi, kuyakudambisa ukuhamba emhlabeni futhi kukwenza kube budlabha kakhulu.
- Umzimba ushesha kakhulu, ngakho-ke, ungantanta ngokukhululeka okukhulu. Umoya ungena eboyeni bawo futhi ubenze bube buncane kakhulu. Le yindlela ongantanta kalula ngayo.
- Ngenxa yamapayipi ematheni nentshebe ebucayi, iyakwazi ukusesha nokubamba inyamazane yayo, noma ngabe amanzi ayaqhaqhazela noma anamafu.
- Ososayensi bazifundile kaningi lezi zilwane futhi baphetha ngokuthi umuzwa wokuhogela ubaluleke kakhulu kunokubona ukuze uqaphele futhi ubhekele labo abangaba yizisulu.
Indawo nendawo okusatshalaliswa kuyo
Indawo lapho lolu hlobo lusatshalaliswa kakhulu isendaweni eseNyakatho Pacific. Isuka enyakatho yeJapane iye eBaja California eMexico. Indawo yokuhlala enkulu yizindawo lapho amanzi asogwini ejulile khona. Ngokuqondile ikakhulukazi ngamamitha ayi-15 kuye kwangama-20.
Ezikhathini eziningi bangabonakala bebhukuda eduze nogu ngenxa yobukhona bezindawo ezivikelekile emimoyeni enamandla yasolwandle. Kulezi zindawo i- otter yasolwandle ithatha ithuba lokuphumula ingalwi nemisinga.
Ezinye izindawo lapho singazithola khona zingamahlathi aminyene e-kelp, izinto ezinamadwala, nezithiyo zemifula. Ngokuya ngasenyakatho bayayeka ukusabalala ngenxa yokuba khona kweqhwa lase-Arctic.
Ukudla
Ngenxa yemetabolism yayo esheshayo, i-otter yasolwandle idinga ukudla njalo. Badinga ukumunca izakhamzimba ezihlanganisa phakathi kuka-25 no-40% wesisindo somzimba wabo. Zidla inyama futhi ukudla kwazo okuyinhloko izinambuzane ezingenamgogodla zasolwandle ezinjengezimbaza, iminenke, ama-sea urchin nezinye izinhlanzi ezincane.
Ukuze badle lokhu kudla badinga ukuvula amagobolondo noma basebenzise amatshe nezinkuni ukubasiza. Lezi zenzo zidinga ikhono elithe xaxa futhi ngalokho zinomunwe wazo omude kunayo yonke. Njengoba ingahlali ikudla konke ukudla ekutholayo, i- otter yasolwandle isungule uhlelo lokuzivumelanisa nalezi zimo ukugcina ukudla kwayo iphinde ikudle kamuva.
Kuyisikhwama abasenzile ngesikhumba sabo esinwetshiwe nesixegayo ethangeni labo lapho ungabeka ukudla ongeke ukudle okwamanje nokuthi itholakala ngokuqhubekayo ngenkathi ibhukuda noma icwilisiwe. Lapho isikhwama sakhe sesisuthi noma silambile, usebenzisa uboya bakhe ukuzigingqa, antante emhlane wakhe, futhi azitholele yena konke ukudla okugciniwe.
Ukuzala
I-otter yasolwandle inentsha unyaka wonke, noma kunjalo zivame kakhulu ezinyangeni zikaMeyi noJuni lapho amazinga okushisa eba mnandi kakhulu futhi kukhona inala yokudla. Isikhathi sokukhulelwa kwentsha imvamisa sithatha izinyanga eziphakathi kwezine nezingu-4. Lo mehluko obanzi ubangelwe ukuthi kubambezele ukufakwa. Lokhu kungenxa yokuthi insikazi inethuba lokuqanda iqanda alifakile ukuze likhule lapho izimo zezemvelo zikuthanda kakhulu ukuzala kwalo.
Le yindlela enhle kakhulu yokusinda lapho ubhekene nezimo ezingezinhle zemvelo.
Ngiyethemba ukuthi ngalolu lwazi uzokwazi kangcono i-otter yasolwandle.
