Ukwakheka Nokuzivumelanisa Nezimo Zezilwane Zasolwandle
I-Pendahuluan
Izilwane zasolwandle zinezinhlobo ezahlukene zezimo, ubukhulu, kanye nokusebenza kwazo ukuze ziphile ezindaweni eziguquguqukayo kakhulu futhi ngezinye izikhathi ezingafaneleki. Ukuhlukahluka kwazo kwesimo kanye nokuzivumelanisa nezimo kuvumela ukuthi zihlale ezindaweni eziningi zemvelo, kusukela emanzini angajulile kuya ekujuleni kolwandle okukhulu. Kulesi sihloko, sizohlola ngokujulile izimo zomzimba ezahlukahlukene (izakhiwo) kanye nokuzivumelanisa nezimo kwezilwane zasolwandle ezizivumela ukuthi ziphile futhi zichume ezindaweni zazo eziyinkimbinkimbi zokuhlala.
Ukwakheka Kwezilwane Zasolwandle
Isimo somzimba
Esinye sezici eziphawuleka kakhulu ngesimo sezilwane zasolwandle ukuma komzimba wazo. Ukuma komzimba kungahluka kakhulu kuye ngokuthi isilwane sihlala kuphi kanye nendlela yaso yokuphila.
1. Inhlanzi:
Izinhlanzi zinezinhlobo ezahlukene zomzimba ezifanele izindawo zazo. Izinhlanzi ezithambile njenge-tuna kanye ne-mackerel zinemizimba ye-fusiform, ehlelekile futhi enamandla okubhukuda ngokushesha emanzini avulekile. Izinhlanzi ezihlala phansi njenge-flounder, ngakolunye uhlangothi, zinemizimba eyisicaba nebanzi ezisiza ukuba zizifihle phansi kolwandle.
2. Izilwane Ezincelisayo Zasolwandle:
Izilwane ezincelisayo zasolwandle njengemikhomo namahlengethwa zinemizimba efana ne-torpedo enciphisa ukumelana kwamanzi ukuze zibhukude ngokushesha. Amaphiko azo afana nokugwedla (ama-flippers) avumela ukushelela okuhle kakhulu ngenkathi zibhukuda.
3. Izilwane Ezingenamgogodla:
Izilwane ezibizwa ngokuthi ama-crustacean njengezinkalankala zinezigobolondo eziqinile kanye nemisila eqinile yokuzivikela nokuhamba. Izilwane ezifana ne-squid kanye ne-octopus zinemizimba ethambile enezingalo ezinde noma ama-tentacles, ezisiza ukubamba inyamazane futhi zisebenzisane nendawo ezikuyo.
Isakhiwo Se-Anatomical
Isakhiwo somzimba sezilwane zasolwandle siphinde sivumelane nendawo yasemanzini. Ezinye izindlela zokwelapha zihlanganisa:
1. Ama-Gill:
Ama-gill yizitho zomzimba ezivumela izilwane zasolwandle ukuthi ziphefumule ngokuhlunga umoya-mpilo emanzini. Lezi zakhiwo zisebenza kahle kakhulu ekushintshisaneni kwegesi futhi zitholakala ezinhlanzini, ezinhlotsheni zezinhlanzi ezinamagobolondo, kanye nakwezinye izimbaza.
2. Isikhumba kanye nezikali:
Isikhumba sezilwane zasolwandle sivame ukuba sikhulu noma sibe bushelelezi ukuze sivikeleke futhi sivimbele ukulahleka kwamanzi. Amaxolo ezinhlanzi ahlinzeka ngesivikelo esengeziwe somzimba futhi anciphise ukungqubuzana ngenkathi ebhukuda.
3. Amaphiko nomsila:
Amafin asetshenziselwa izitayela ezahlukene zokubhukuda, kanti umsila usiza ekuqhubeni. Ukuma kwamafin nemisila kuyahlukahluka phakathi kwezinhlobo kuye ngesivinini kanye nesitayela sokunyakaza esidingekayo.
Ukuzivumelanisa Nemvelo
Ukuzivumelanisa nezimo zemvelo kuyizinguquko emisebenzini yomzimba ezivumela izilwane zasolwandle ukuthi zisinde ezimweni ezimbi kakhulu zemvelo yasolwandle. Lokhu kuzivumelanisa nezimo kuhlanganisa izici eziningi, kusukela ezindleleni zokuphefumula kuya ekubekezeleleni ukucindezeleka okuphezulu.
1. Ukufakwa komoya-mpilo:
Ezinye izilwane zasolwandle, njengemikhomo nezimvu zamanzi, zinekhono lokubamba umoya wazo isikhathi eside kakhulu. Lokhu kwenzeka ngenxa yokugcina umoya-mpilo kahle emisipheni nasegazini lazo, kanye nekhono lazo lokunciphisa izinga lokugaya ukudla kwazo ngenkathi zicwila emanzini.
2. Ukulawulwa kwe-Osmoregulation:
Ukugcina ukulinganisela kosawoti namanzi kuyinselele enkulu ezilwaneni zasolwandle. Izinhlanzi zasemanzini anosawoti kumele zikhiphe usawoti omningi njalo emathunjini azo nasemchameni. Ngokuphambene nalokho, izinhlanzi zasemanzini ahlanzekile zimunca usawoti endaweni ezizungezile ngenkathi zikhipha amanzi omningi.
3. Ingcindezi:
Ezinye izilwane zasolwandle zingaphila ekujuleni okukhulu, lapho umfutho wamanzi uphakeme kakhulu. Ukuzivumelanisa kwazo kuhlanganisa izakhiwo zomzimba eziguquguqukayo nama-enzyme ahlala eqinile ngaphansi kokucindezeleka okukhulu.
Ukuzivumelanisa Nokuziphatha
Ukuzivumelanisa nokuziphatha nakho kudlala indima ebalulekile ekusindeni kwezilwane zasolwandle. Lokhu kuzivumelanisa kungafaka phakathi ukuyofuna ukudla, ukuzala, kanye nokuxhumana nabantu.
1. Indlela Yokuzingela:
Izindlela zokuzingela ziyahlukahluka kakhulu phakathi kwezinhlobo. Oshaka, njengoshaka, basebenzisa umuzwa wabo wokuhogela kanye nokwamukela ngogesi ukuthola inyamazane. Amahlengethwa asebenzisa i-echolocation ukuthola izinto ezizungezile.
2. Ukukhiqiza:
Ezinye izilwane zasolwandle zinezindlela eziyinkimbinkimbi zokuzala. Isibonelo, ama-coral reef aziwa ngokukhipha amaqanda amaningi kanye nesidoda, okubizwa ngokuthi i-spawning, okuvame ukubangelwa yizigaba ezithile zenyanga noma amazinga okushisa kwamanzi.
3. Iphethini Yokuhamba:
Ukufuduka kungenye indlela ebalulekile yokuzivumelanisa nokuziphatha. Isibonelo, i-salmon ifuduka isuka olwandle ibuyela emifuleni yayo yasekhaya ukuze izale. Izimfudu zasolwandle zaziwa nangokubuyela emabhishi lapho zazalela khona amaqanda azo.
Ukuzivumelanisa Nemvelo
Ukuzivumelanisa nemvelo kuhlanganisa indlela izilwane zasolwandle ezisebenzisa ngayo indawo yazo ukuze ziphile. Lokhu kungafaka phakathi ukuzivumelanisa nokutholakala kokudla, ukuncintisana, kanye nokudla ezinye izilwane.
1. Ukusebenzisana:
Ezinye izinto eziphilayo zasolwandle zinobudlelwano obuzuzisayo obuzuzisayo. Isibonelo yi-sea anemone kanye ne-clownfish. I-anemone ivikela i-clownfish, kanti i-clownfish ihlinzeka ngokudla kwe-anemone ngokuheha izisulu.
2. Ukucasha kanye nokufanisa:
Izilwane eziningi zasolwandle zisebenzisa indlela yokuzifihla noma yokulingisa ukuze zigweme izilwane ezidla ezinye noma zixoshe izilwane ezizingelayo. Izinhlanzi ezibizwa ngokuthi ama-cuttlefish nama-octopus zingashintsha ngokushesha umbala kanye nokuthungwa kwesikhumba sazo, kuyilapho ezinye izinhlanzi, njenge-lionfish, zineziphethini zemibala ezilingisa indawo ezizungezile.
3. Ukuncintisana kanye ne-Niche:
Izinhlobo zasolwandle zinezindlela ezahlukahlukene zokunciphisa ukuncintisana nokwandisa ukusebenza kahle kwamandla. Ezinye izinhlobo zingase zibe sebusuku ukuze zigweme ukuncintisana ngqo nezinhlobo zezilwane eziphila usuku ngalunye, kanti ezinye zingase zithuthukise ukudla okukhethekile ukuze zisebenzise izinsiza ezingasetshenziswanga ezinye izinhlobo.
Isiphetho
Ukuhlukahluka kwesimo sezilwane zasolwandle kanye nokuzivumelanisa nezimo kugqamisa ubunzima kanye nobuchwepheshe bempilo yasolwandle. Kusukela ezimweni zomzimba ezihlukile kuya ekuzivumelaniseni nokuziphatha okuyinkimbinkimbi kanye nemvelo, izilwane zasolwandle zihlala zithuthuka ukuze ziphile ezindaweni eziguquguqukayo nezinselele. Ucwaningo lwesimo sezilwane zasolwandle kanye nokuzivumelanisa nezimo alugcini nje ngokucebisa ukuqonda kwethu ngebhayoloji yasolwandle kodwa futhi lunikeza ukuqonda okubalulekile kokulondolozwa kanye nokuphathwa okusimeme kwezinhlelo zemvelo zasolwandle.
