Abadobi be-Proroy nabanikazi be-aquarium babuza umbuzo: ingabe izinhlanzi zilala? Umbuzo uvela ngesizathu, ngoba akekho oye wabona izinhlanzi zivaliwe amehlo. Abanakho nje ukuvala - izinhlanzi azinawo amajwabu amehlo. Aziphumuli ngendlela efanayo naleyo evamile kubantu, izinyoni nezilwane ezincelisayo.
ukulala kwezinhlanzi - lesi yisigaba sokuphumula, lapho yonke imisebenzi ihamba kancane, umzimba unganyakazi, ukusabela kuba buthaka. Ezinye izinhlanzi ekujuleni aziphenduli ekushukumiseni kwangaphandle (ungazithinta, ukhanyise ithoshi emehlweni akho). Abanye bazwa ingozi encane. Izinhlanzi eziningi zicishe zinganyakazi lapho ziphumule. Futhi ezinye (i-tuna, oshaka) zihlala zinyakaza, zilele emanzini ngokumelene nomsinga. Uma imifudlana yamanzi ingadluli emathunjini abo, ingaminza.
Izici zokuphumula kwezinhlobo ezahlukene zezinhlanzi
Ukucaciswa kokuphumula kwezinhlanzi kuncike ezinhlotsheni zazo. Ngakho, i-astronotus ilele ngezansi noma ilenge ibheke phansi. I-clown fish ibekwe emgqonyeni ongaphansi kwe-aquarium. Ezinye izinhlobo zezilwane zimane nje zintweza zinganyakazi.
Izinhlanzi zilala kanjani emvelweni?
I-cod - ilele, i-flounder ibhoboza esihlabathini, inhlanzi - isisu sibheke phezulu, sikhukhuleka emanzini. Izinhlanzi eziningi zifuna amakhona acashile ukuze zilale - phakathi kwamatshe, imifantu yamadwala, ulwelwe namakhorali.
Akuzona zonke izinhlanzi ezilala ebusuku. Izilwane ezidla ezinye zasebusuku (i-burbot, i-catfish) zikhetha ukulala emini. Kodwa ngemva kobusuku obungaphumuli, inhlanzi yelanga ingakwazi ukukhokhela “ihora lokuthula” emini. Idlule wonke amahlengethwa (yize lezi zingezona izinhlanzi, kodwa izilwane ezincelisayo). Abalali neze. Ngesikhathi sokuphumula, i-hemispheres yobuchopho babo iphapheme ngokushintshana ukuze ikwazi ukuntanta phezulu futhi ihogele umoya. Isikhathi esisele, zombili i-hemispheres zisebenza. Ngokuvamile, izici zokuzijabulisa kwezinhlanzi zincike kuphela kuhlobo lwazo.
