Silwane yezilwanyana zasemanzini. Iintlobo nezilwanyana zaselwandle

Ngoko ke akukho mfihlakalo ukuba iilwandle kunye neelwandle - indawo zokusasaza kunye nezityalo nezilwanyana ezininzi ezingaqhelekanga, ezintle nje emangalisayo. Kude kube ngoku, izilwanyana iilwandle kunye neelwandle kuveza abaphandi izimanga. Yokuvela wenza izilwanyana emangalisayo, sifunde indlela yabo yokuphila kunye nobudlelwane phakathi kwabo.

Phakathi elwandle ulwandle abemi abamele zonke iiklasi zezilwanyana, ngaphandle iintaka. Kwaye ngoko, ujonge ukuba uluvo lokuba bajonge kuzo. Eneneni, iintaka ezininzi kuzingelwa emanzini, kunye yoonombombiya bonke bahlala olwandle. Kodwa kweli nqaku Ndingathanda ukuhlala ngqo abo ezingangeniyo kwinkcazelo "esanyisayo zezilwanyana zaselwandle."

Izilwanyana kweelwandle neelwandlekazi

Organoleptic nemichiza nokwakhiwa amanzi kwiilwandle kunye neelwandle twatse. Eyahluke umxholo amanzi kuphela iimpawu ezithile kunye nawenkumbulo ngetyuwa. Ngoko ke, izilwanyana zabo nayo efanayo kakhulu. Izilwanyana lula uphume kweelwandle kolwandle, izilwanyana ulwandle zikhula elwandle.

Izilwanyana kula machibi limelwe izilwanyana kwezi ndidi zilandelayo:

1. Esineqokobhe zonke iintlobo.
2. Kwezilwanyana.
3. Fish.
4. Iipolyps.
5. Sponge.
6. Hydroids.
7. Izinambuzane.
8. Emanzini.
9. Ezirhubuluzayo.
10. Ezincancisayo.
11. Birds.

Kucacile ukuba ihlabathi somgquba ezilwandle zahlukahlukene kakhulu kwaye enkulu ngokwemiqathango ngolunya. Phakathi zonke izilwanyana uva esanyisayo ephawulekayo isilwanyana zaselwandle. Amaninzi zifumaneka zombini emhlabeni kunye namanzi. Nangona kunjalo, zikhona abemi kuphela zasemanzini.

Ntlobo zezilwanyana ezincancisayo kwiilwandle

iintlobo Mammalian izilwanyana eziphilayo kwiilwandle kunye neelwandle, umdla kakhulu kwaye eyahlukeneyo kokubini yokuphila kwaye imbonakalo. Cinga abameli eziphambili.

1. Iminenga. Ezi zibandakanya iintlobo ezahlukeneyo: blue, ongwevu, bowhead, iminenga amadlozi, mnenga, iminenga beaked, iminenga minke kunye nabanye.
2. Killer whales. kufutshane kakhulu iminenga, isilwanyana, ababulali eziyingozi elwandle kunye nendawo ulwandle.
3. Dolphins. iintlobo ezahlukeneyo: i bottlenose eku xhulumaneni, klyuvogolovye, brachycephalic, porpoises, belugas kunye nabanye.
4. Tywina. Izilwanyana lohlobo itywina, i zixhaphakileyo - itywina engqongwe.
5. Matywina. Faka iintlobo ezininzi: lionfish, dyondzisiwaka lamatywina, ekusasazweni, yokwenene, seals elineentshebe kunye nabanye.
6. zamanzi ngeendlela ezimbini: ngasentla nangasezantsi.
7. iingonyama Sea.
8. Iinkomo Sea - namhlanje phantse ukubatshabalalisa ezanyisayo izilwanyana zaselwandle zabantu.
9. Walruses.
10. Navy Seal.

Xa iyonke kukho ezingaphezu kwe-120 iintlobo nezilwanyana zaselwandle ezahlukeneyo.

iimpawu ezanyisayo

Njengoko iintlobo ezisentlabathini, elwandle nolwandle izilwanyana, kakhulu, iimpawu ezikhethekileyo, leyo kunganxulunyaniswa kwiklasi ezincancisayo. Zeziphi izilwanyana ezanyisayo?

1. Njengazo zonke amalungu kule klasi, luphawulwa lusidla ubisi yabantwana babo ngenxa amadlala ezizodwa mammary ukuba nezilwanyana zaselwandle kunye ulwandle.
2. Ezi zilwanyana hatching ngaphakathi inzala (Esibelekweni) kwaye lokuyivelisa kunye ukuzala live.
3. Oku izilwanyana poikilothermic (ezinegazi elishushu), kuba namadlala xhopho, ngomaleko omkhulu womhlaba ze ongama fat glycogen.
4. Emngxunyeni ekhoyo, ukuvumela ukuba aphefumle.

Ezi zixhobo ukuba kukhuselekile ukuthwala zonke ezi zilwanyana ukuba ezanyisayo zaselwandle kunye ulwandle.

Iimpawu eziphilayo zaselwandle izilwanyana

Izilwanyana kweelwandle neelwandlekazi eziliqela izixhobo ukuze bazive bezithembile yaye sikhuselekile isibhakabhaka emanzini. Umzekelo:

• imilenze similise zinamaphiko intshukumo fast;
• abaninzi kubo bomelele, amazinyo abukhali (kwiintshaba nezidla);
• ngokobukhulu enkulu igqunyelelwe ngomaleko omkhulu womhlaba ze kukutyeba ongama;
• ukumila streamlined, nto leyo eyandisa isantya intshukumo;
• kunokwenzeka ukuba zithumele iimpawu audio enye kwenye (uninzi).

Ngokusebenzisa zolo ulwandle ocean izilwanyana yokuhlalisana kunye nabanye kunye nehlabathi ngaphandle. Amaninzi, ezanyisayo yolwandle izama ukugcina abathanda abantu. Oku uphawu abo bangakwaziyo ukuzikhusela ezinkulu ezizingelayo ngaphandle lokuphuma (lamatywina, iilynx, seals, iingonyama, seals).

Abanye, Noko ke, bakhetha ukuba abe yedwa. Kuyinto elula ukuba ekuzingeleni abathile ixhoba (iminenga amadlozi, orcas, iintlobo karhataka of amahlengesi kunye neminenga).

Ukwazi ukuba adlulisele imiqondiso isandi omnye komnye kubaluleke kakhulu. Ngoko ke kunokwenzeka ukuba alumkise malunga ingozi kwexesha ukukhusela wena. Kwakhona, ekubeni unako ukwabelana kunye nezalamane ukutya.

Umfanekiso ezanyisayo zaselwandle abaphila imini ngaphandle ezinqabileyo. Ebusuku, bakholisa ukuba aphumle. Nangona kunjalo, kukho iimeko (ezinye iintlobo iminenga, zamanzi zasebusuku).

Mammals kolwandle

Ezanyisayo izilwanyana zolwandle ezinambuzelayo kanye emazantsi ezinzulwini ezilwandle - i dugong okanye ulwandle cow (siren). Le isilwanyana akuyongozi kwaphela, oko ufaneleke igama layo, kuba uyawondla izityalo kuphela ezantsi.

Imilinganiselo Umyinge kuthelekiswa nezinye izilwanyana ezanyisayo elwandle: 4 m ubude, ubunzima malunga 600-650 kg. Man lula idade kufuphi imazi ulwandle nkqu akazukuyibamba, ukuba icala. Le isilwanyana uthando kakhulu, zilulamile nibe umntwana.

Ukongeza, le isilwanyana ngomnye omdala kule planethi (wabonakala malunga nezigidi ezingama-50 kwiminyaka eyadlulayo), oko idweliswe eNcwadini oluBomvu. Oku mhlawumbi ummeli kuphela, ebhekisela kudidi "izilwanyana olwandle."

Ezinye ezanyisayo zaselwandle bakhetha ukuba bachithe ixesha labo kule kumphezulu okanye kwikholam emanzini, kunqabile wayetshona ukuya ezantsi.

Esi silwanyana kakhulu eyingozi ezilwandle

Izilwanyana ocean kakhulu eziyingozi ziquka:

1. Iminenga Killer (orcas). Ubunzima ngaphezu kweetoni eziyi-8, enye ubude-10 m Savage umbulali ukondla intlanzi enkulu, ezincancisayo kunye congeners babo -. Iminenga.
2. yiminenga isidoda. Bahlasela ubukhulu squid, ngwane saselwandle esineqokobhe omkhulu, ukudla intlanzi enkulu. ubunzima yezilwanyana olumalunga 50 etoni, kwaye ubude - angaphezu kwe-20 m.
3. iingonyama Sea. Likhangeleka izilwanyana ezithandekayo nibe rhoqo ukuhlasela umntu ngokungqongqo kuzilinda izinto zawo. Ukongeza, ukuba ezidla size sizondle iintlanzi, izilwanyana ezincinane.

Kakade ke, kukho iingozi ezininzi igcinwe kule elwandle. Noko ke, phakathi eziphila elwandle kakhulu eziyingozi abameli zikhankanywe apha ngasentla ezincancisayo. Abanye - nokuba Azityi okanye sisitya kwizidalwa okanye izilwanyana ezincinane.

Uninzi izilwanyana ezinkulu ulwandle

Kuba izilwanyana kakhulu enkulu izilwanyana ziquka bameli balandelayo:

1. I blue okanye whale - ubude ifikelela 33 m sobunzima wayo yahluka ukusuka kwiitoni ezingama-90 ukuya kwezili-120 .. Enye kuphela intliziyo wentlanzi ubunzima ngaphezu kwama-600 kg!
2. Southern elephant - ubude laliziimitha 6 Weight ukusuka kwiitoni ezingama-5 ukuya ku-6 .. Ukongeza ubungakanani ezukileyo, ezi zilwanyana nazo kwiintshaba - kuyingozi ikrakra. Uyakwazi ukuba emanzini ukuya kubunzulu ngaphezu kwewaka leemitha, ukuba wabeka usukelo lokuzikhumbuza kunye ixhoba, enoba kunjani na.
3. Walruses ukufikelela ubude beemitha-4 kwaye inobunzima ukuya kwiitoni-2. ubukhulu encomekayo kakhulu ngumlinganiswa engeyongozi ngokupheleleyo - yidla ezingenamqolo ezincinane, nibaphanga eludakeni nesanti kwi emazantsi imimandla yaselunxwemeni. Ezinkulu Sony, chitha ixesha elininzi ilele kwiqela phezu chibi.

Uninzi izilwanyana engeyongozi kweelwandle neelwandlekazi

Indlela abiziweyo izilwanyana zaselwandle, ezo ulwandle ezanyisayo kunye nolwandle isithuba kakhulu ayinabungozi? Impendulo yaziwa yonke yesikolo: Kakade ke, dolphins bottlenose! Abathandi ukuqubha nabantu, nobubele, ezintle - (! Ukuya ukuphakama kuyimitha 6) Ewe, udlala, yegadi, jump abakhulule kumnandi nolonwabo ebantwini.

Kukho kwakhona zaselwandle ingozi izilwanyana ziquka lamatywina, iilynx, zamanzi ezinye whales.
