Ngubani Uhlala kumgangatho olwandle?

Ngubani ohlala phezu kolwandle, kuyaziwa: intlanzi, isilwanyana, iintshulube zaselwandle, intlanzi, kunye nezinye abameli izilwanyana uphawu emanzini. Kodwa kwiimeko zentlalo kubunzulu eyahlukileyo kakhulu kwezo kweshelfu elizwekazi ungqameko aphezulu landelanisa yolwandle. Ngoko ke, abemi anzongonzongo ziye iindlela zokhuselo apho ubukho babo kunokwenzeka.

wokunciphisa Ukukhanya spectrum elanga ingena ububanzi yolwandle kubunzulu ezahlukeneyo. Rays bokukhanya bomvu naorenji - hayi ngaphezulu kwe mathathu iimitha ukuya ikhulu elinamanci asibhozo - mthubi, phezulu ukuya amathathu, anamanci mabini - eluhlaza, ukuya isiqingatha ngekhilomitha - oluhlaza. Nangona izixhobo ezininzi vakalelo mihla kwabhalwa imizila kwelanga ukuya kubunzulu kweekhilomitha enye enesiqingatha, sinokuthi: amakhulu amahlanu eemitha ngezantsi kubusa ocean yomisa ubumnyama. Bonke abo bahlala phantsi zolwandle ngezantsi olu phawu, bebeziqhelanisa yokunqongophala ukukhanya ngeendlela ezahlukeneyo. Abanye baye supersensitive uhlobo amehlo owawusisibonakude, nako makathathe izixhobo ezimbalwa ukukhanya ekhoyo ufaka isicelo. Okanye mhlawumbi esiphakame ubuntununtunu kwaye ivumela ukuba ukuhamba naphi idlule nkqu oomatshini yabantu. Ezinye izilwanyana phambi jikelele bamshiya kwaye kakhulu kakuhle ngexesha va efanayo. Abanye abahlala kumazantsi wabufumana ubuchule nokuvelisa ukukhanya ngokwabo.

A phawu uphawu emgangathweni wolwandle - ukudla. Ngenxa lobushushu ephantsi (2-4 degrees ngasentla zero), zonke iinkqubo ke ukuthatha indawo apho ngababuthuntu, yaye hayi abemi enzulwini olwandle intshukumo fast okanye umsebenzi kakhulu ekufumaneni ukutya. Phantse zonke izilwanyana kukho ngamarhamncwa. Ngenxa encinci ukutya intlanzi olunzulu-elwandle ithole ukukwazi baginye izidalwa ukuba mkhulu kunabo.

Ocean umgangatho ezimpahleni ke lendle zamafu. Kulo mba, ezinye zezilwanyana ezinzulu-ulwandle (umzekelo, izigcawu ulwandle) babe ngamalungu elide, ebavumela ukuba mandingaweli ezike. Ekubeni iintlanzi ezininzi abasuka rhoqo ukusuka ezantsi ukuya phezulu nokubuya, ngamanye amaxesha kunzima ukuba sibone apho umntu ubomi. Emazantsi olwandle eninzi yengcinezelo, ukukhanya encinane, ukutya, iqondo elisezantsi. Ngoko ke, ezinye iintlobo ezinzulu-ulwandle wambi ezifumaneka umphantsi nomphezulu emanzini, babe ngamaxhoba ababambisi beentlanzi, akumangalisi ukuba imbonakalo yazo engaqhelekanga. Ngoko ke, umzekelo, ngokufuthi kweyela network iintlanzi-nowiso, yokuba "ubuso" izalelwe funny ongathi impumlo ilenga.

Intlanzi phezu kolwandle kakhulu kaninzi uhlobo kujoliswe kulo, kodwa iisampulu esikhulu ngenxa yezizathu ezicacileyo (ukunqongophala kokutya) zinqabile. Umzekelo, amalahle iintlanzi. Nangona yena uhlala e kubunzulu ukuya kwiimitha 2700, xesha kaninzi koovimba. Amazwe athile amagama ahlukeneyo iintlanzi. Sinawo - amalahle e Canada - cod emnyama, kwi-US - intlanzi Sable, Australia - oyile iintlanzi. Phakathi kwabo bemiyo phezu kolwandle, isidalwa - ingxilimbela. Ubude le mbelukazi ezinkulu ifikelela 120 cm.

Ubomi ezinzulwini zolwandle kakubi kakhulu wafunda, kwaye kunokwenzeka ukuba silindele ezifunyaniswe ezinkulu. Ngamaxesha athile pops up inkcazelo ukuba abalobi bahlangana phakathi izithuba wolwandle izilwanyana ongaziwayo, abanye bade waba kubuthwe gongqongqo. Kakade ke, uninzi ezi ngxelo amarhe okanye iintsomi elwandle ngokufanayo, kodwa aninjalo nonke. yiminyaka elikhulu elinamanci eyadlulayo nzima umntu izazinzulu ezinkulu nakholwa ukuba coelacanth - iintlanzi wabonakala elide phambi kokuba Dinosaurs, wesimanje wethu. Noko ke, kamva ke kwaba ubukho abalobi Afrika, izazinzulu ziye kungeniswa a ndlovu ngqo.
