Inhlanzi esezansi

Kuwo wonke umlando weplanethi yethu kube nezinhlobo eziningi zezilwane ezidlule kuwo. Kodwa-ke, akusikho konke okuqhubekayo namuhla, kungaba ngezinhlekelele noma ngenxa yokuthi abafinyelelanga kuzinqubo zokuziphendukela kwemvelo ezidingekayo ukusinda ekuhambeni kwesikhathi nokuziphendukela kwemvelo uqobo. Lokhu akunjalo ngenye yezinhlanzi ezihluke kakhulu laphaya. Ngikutshela mayelana izinhlanzi kwalasha.

Inhlanzi yakwalasha ngesinye sezidalwa esezivumelane kahle nempilo esemanzini, iya kwelinye igxathu. Lesi silwane senze izindawo ezikude kakhulu zasemanzini ikhaya laso elintofontofo.

Impela, iningi lenu kungenzeka ukuthi kalizwanga ngaye ekuqaleni noma lazi igama lakhe ngokungacacile. Yingakho kule ndatshana sizothola le nhlanzi eyingqayizivele futhi ehlabayo, ikubonise izici zayo, izindawo zokuhlala kanye nokuziphatha kwayo, kanye nezinhlobonhlobo zezinhlanzi zakwalasha ezikhona.

Habitat

Njengoba sishilo ekuqaleni, inhlanzi yakwalasha iguqule ikhono lokuzivumelanisa nemvelo libe ubuciko. Kube njalo, ukuthi lezi zinhlanzi zihlala ezindaweni zezilwandle nezilwandle lapho impilo incane khona.

Njengomthetho ojwayelekile, inhlanzi yakwalasha ikhula olwandle lapho ukujula kwayo kungaphezu kwamamitha ayi-1000. Eqinisweni, kulezi zindawo ukukhanya kwelanga kuncane, uma kungenjalo zero, futhi ukucindezela kuphezulu kakhulu. Izinhlobo eziningi ezahlukene de peces kwalasha bakwazile ukuhlala ezindaweni zasolwandle phakathi kwamamitha ayi-6000 no-9000 ukujula.

Phakathi kwezindawo esiziqhakambisile njengezindawo zokuhlala izinhlanzi kwalasha, kufanele siveze ukuthi ziveza inkomba yamanzi afudumele olwandle lwasePacific nolwamaNdiya.

Izici zenhlanzi yakwalasha

Ukuhlala ekukhanyeni okuphansi nezimo ezinengcindezi ephezulu kube nomthelela omkhulu ekubukekeni nasezimfanelweni zenhlanzi yakwalasha, okuthi uma ivelela okuthile yenzelwe ubuso bakhe obukhulu lokho kusenza sikubone njengesidalwa esivela komunye umhlaba. Izitho nezicubu zomzimba wakho zinamanzi amaningi ukulinganisa ingcindezi yangaphandle abekwe kuyo, futhi ukungaboni okukhanyisa ukukhanya kwenza iphunga libe ngenye yezinzwa ezithuthuke kakhulu.

Cishe, into ehlaba umxhwele kakhulu ngenhlanzi esezansi yikhanda layo elikhulu elincike kakhulu emlonyeni omkhulu nobanzi, kuhlanganiswe namazinyo amade kakhulu. Konke lokhu kuqhathanisa nawo wonke umzimba wakhe ovame ukuba mncane. Njengomthetho ojwayelekile, izinhlobo ezahlukahlukene zezinhlanzi zakwalasha awavame ukudlula amasentimitha angama-20 ubude.

Amehlo mancane kakhulu, futhi awakusizi ngalutho kuwe. Umbala wabo wesikhumba umpofu kakhulu, futhi kukhona ngisho nezinhlanzi zakwalasha ezikwazi ukubonisa ukukhanya noma ukuba ngandlela-thile zicace bha.

Ukudla

Ukudla okwenziwa yizinhlanzi zakwalasha kungabekwa njengokuhlukahluka okuthile, ngoba kulezi zindawo ezingathandeki zomhlaba ukukhululeka kokudla akuyona into enhle.

I-Zooplankton nezilwane ezahlukahlukene ezincane kakhulu seziphenduke inkanyezi kwimenyu yezinhlanzi yalasha.. Kodwa-ke, lezi zinhlanzi nazo ziyizilwane ezidlayo futhi zikhombise izindlela ezithile zokuzingela (njengezitho ezikhanyayo eziheha inyamazane, ebizwa ngokuthi isithombeevumela ukuthi ubambe ama-minnows amancane ngokungezelela kwamanye ama-mollusk nama-crustaceans. Bangakwazi futhi ukugwinya ezinye izinhlanzi ezinkulu ngenxa yokuqina kwesikhumba sabo kanye nezabo izisu ezandekayo.

Njengoba kungenzeki kaningi ukuthi abanalo ithuba lokudla nsuku zonke, banesifo somzimba esisheshayo.

Ukukhiqizwa kabusha kwenhlanzi yakwalasha

Ezikhathini eziningi, into enzima nokuningi ukuhlukanisa ezinhlanzini umehluko phakathi kwesifanekiso sowesilisa nowesifazane. Endabeni yenhlanzi esezansi, i-dimorphism yezocansi ibaluleke kakhulu.

Owesilisa mncane kakhulu kunowesifazane, cishe angaphansi kweshumi ncamashi, ngakho-ke umkhuba wokuzala uyamangalisa futhi uyamangaza. Abesilisa baluma esiswini sowesifazane futhi ngokoqobo baba uhlobo lokwelulwa komzimba wakhe. Uma lokhu sekwenzekile, owesifazane uthumela ukudla kowesilisa, kuyilapho yena ephindisela ngokunikeza isidoda ngendlela eqhubekayo. Uhlobo lwe-symbiosis enelukuluku ngaleyo ndlela lutholakala okungenani.

Isenzo sokukhiqiza asenzeki njalo kakhulu, lokhu kungenye yezimbangela zokuthi impilo yalezi zinhlanzi yinde kakhulu.

Izinhlobo zezinhlanzi kwalasha

Njengoba kade sibonisa kuso sonke lesi sihloko, izinhlanzi zasolwandle ezijulile ziyiqembu de peces okuhlanganisa izinhlobo ezahlukene zezilwane ezinezici ezifanayo, ukuziphatha kanye nendlela yokuphila.

Phakathi kwazo zonke siqokomisa Izinhlanzi zasePelican (Euryphaynx pelecanoides), ohlala ngaphansi kwamamitha ayi-8000 futhi unomlomo omkhulu; i Inhlanzi Yedrako (Stomias boa) ohlala ngaphakathi kwamamitha angama-4500 futhi ubonakala ngamazinyo ayo anamandla; kanye ne- I-Spiny Fish (Himantolophus appelii) enosayizi wamasentimitha ama-4 kuphela ubude.
