Liwiro lakuyenda kwa kamba pamtunda ndi m'madzi: momwe akamba a m'nyanja, pamtunda ndi makutu ofiira amathamangira ndi kusambira (kuthamanga kwapakati komanso kopitilira muyeso)

M’chikhalidwe cha mayiko amene kale anali Soviet Union, chithunzi cha kamba n’chogwirizana kwambiri ndi kuchedwa. Pazilumba za Fiji, chokwawa, m'malo mwake, ndi chizindikiro cha liwiro. Anthu okhalamo amalemekeza nyamazi chifukwa cha luso lawo loyang'ana bwino komanso kufulumira komwe zokwawa zimawonetsa m'madzi.

Zomwe zimakhudza kuthamanga kwa kamba:

• kulemera ndi kapangidwe ka chipolopolo;
• thupi la anatomy;
• Kutentha kwa thupi;
• mkhalidwe wamalingaliro;
• mawonekedwe apamwamba;
• zaka ndi thupi mawonekedwe.

Kutalika kwa miyendo mwa oimira mitundu yomwe imatha kubisala miyendo yawo ndi mutu pansi pa chipolopolo ndi yayifupi, chifukwa chake mphamvu zawo ndizochepa kwambiri kuposa zamoyo zomwe sizingathe kuchita izi (akamba amutu waukulu, kamba, akamba am'nyanja).

Liwiro la kamba pamtunda ndi locheperapo poyerekeza ndi madzi.

Liwiro lamtunda

Zokwawa, zomwe miyendo yawo imawoneka ngati zipsepse, zimayenda momasuka, koma osati mochedwa. Pamalo omasuka, chokwawa chimakonda kukwawa pang'onopang'ono. Kuwonjezeka kwa liwiro kumachitika ngati nyamayo ikuwona zoopsa, kapena ikufuna kwambiri chinthu china chapatali. Thamangani, m'lingaliro lonse la mawu, mwachitsanzo, kuti musakhudze pansi, chokwawa sichingathe. Koma ngati n'koyenera, iwo kwambiri imathandizira.

Akamba athupi lofewa amathamanga kwambiri. Chifukwa cha ossification ofooka ndi mawonekedwe athyathyathya a chipolopolo, amatha kuthamangira mwachangu kumitengo yayikulu. Liwiro lalikulu la kamba pamtunda ndi 15 km / h.

Achinyamata ndi othamanga kuposa akuluakulu, moyo wawo umadalira kuthengo.

Miyala ya m'madzi pamtunda imamva kuti ndi yovuta, chifukwa cha mapangidwe a paws, kukumbukira kwambiri zipsepse. Iwo ndi otsika kwambiri pakuyenda mofulumira ku mitundu ya madzi opanda mchere, koma amapikisana kwambiri ndi zamoyo zapamtunda.

Liwiro la kamba wapamtunda kaŵirikaŵiri limakhala lochedwa kuposa la mitundu ya m’madzi opanda mchere. Chakudya cham'mera sichifunikira kugwidwa, motero chisinthiko chasankha chipolopolo kukhala njira yofunika kwambiri yodzitetezera. Pakakhala ngozi, ndikwanira kuti abise mutu wawo ndi mapazi awo.

Kuthamanga kwakukulu kwa fulu yamtunda pafupifupi sikudutsa 0,7 km / h. Mbiri yojambulidwa yovomerezeka idakhazikitsidwa ndi mtundu wa kambuku ndipo ndi wofanana ndi 0,9 km / h.

Kamba wamkulu wa Seychelles amadziwika kuti ndi wochedwa kwambiri pakati pa akamba akumtunda. Mu mphindi imodzi, amatha kugonjetsa mamita 6,17, chifukwa mayendedwe ake saposa 0,37 km / h.

Akamba a Gopher ndi nyenyezi amathamanga pang'ono, pafupifupi 0,13 m / s. Pa nthawi yomweyi amatha kuphimba mamita 7,8.

Liwiro lapakati la kamba wamtunda ndi 0,51 km/h.

Eni ake a nyama zaku Central Asia amawona kuti ziweto zimagwira ntchito komanso zogwira ntchito. Kamba wa ku Central Asia amatha kuyenda mamita 468 mu ola limodzi. Kuthamanga kwake sikudutsa 12 cm / s. Nthaka yosakomera si vuto kwa chokwawa. Malo otsetsereka ndi zinthu zotayirira pansi sizingamulepheretse kupita patsogolo.

Liwiro la kuyenda m'madzi

Zamoyo zapamtunda zimatha kukhala m'madzi kwakanthawi, koma anthu ambiri sangathe kusambira. Kukhala nthawi yayitali kunja kwa chilengedwe ndikowopsa kwa nyama. Matabwa osakhala ndi ukonde komanso mawonekedwe otalikirapo a carapace sanapangidwe kuti azithamanga m'madzi.

Akamba am'madzi amakhala ndi nembanemba pakati pa zala, chipolopolocho ndi chochepa komanso chosalala. Izi zimawathandiza kuti azithamanga mofulumira. Mphamvu zimathandizira kusaka bwino nsomba ndi nyama zam'madzi.

Akamba aakulu amtundu wa leatherback amasambira kuwirikiza ka 14 liŵiro la shaki wa ku Greenland ndipo pafupifupi mofanana ndi lija la namgumi.

Liwiro la akamba am'madzi m'madzi ndi lalitali, popeza chipolopolo chowongolera, chowulungika ndi miyendo yakutsogolo yooneka ngati zipsepse zimathandiza kwambiri pakuya. Pa avareji, amakhala apamwamba kwambiri pamitundu yamadzi am'madzi iyi.

Zitsanzo za liwiro la kusambira kwa miyala yam'madzi:

• nyanja - 18 Km / h;
• nyanja yobiriwira - 32 km / h;
• kamba wachikopa - 35 km / h.

Kuthamanga komwe kamba amasambira sikutengera deta yake yakuthupi. Zomwe zingatheke zimakhudzidwa ndi kayendetsedwe ka kayendetsedwe kake, kachulukidwe ndi kutentha kwa madzi.

Vidiyo: kusambira ndi kamba

Liwiro la kamba la makutu ofiira

M'malo ake achilengedwe, zakudya za kukongola kwa makutu ofiira ndi mapuloteni 40%. Nkhono ndi nsomba zazing'ono zimadyedwa. Pakatha mphindi imodzi, nsomba zam'madzi zimakhala ndi liwiro la 0.3 m, ndipo zimatha kufika 2 m / s, zomwe sizilepheretsa chokwawa kusaka. Akamba amasambira pa liwiro la 5-7 Km / h, ndipo liwiro lalikulu la kamba lofiira limatha kupitilira ziwerengero izi.

Pamtunda, kamba wa makutu ofiira ndi wotsika pang'ono poyerekeza ndi zolemba zake zomwe zili m'madzi. Zikachitika ngozi, nyamayo imakonda kubisala pafupi ndi gwero la madzi, kumene imadzidalira kwambiri.

Kamba wa makutu ofiira ndiye mtsogoleri pakuyenda pakati pa alongo pamawonekedwe. Amatha kuyenda makilomita angapo patsiku. Kuphatikizana ndi njira yabwino yoberekera, izi zimathandiza kuti chokwawa chikhale chofulumira kupanga madera atsopano ndikupikisana ndi anthu okhalamo. Kamba wa makutu ofiira akuphatikizidwa pamndandanda wovomerezeka wa "zamoyo 100 zowopsa kwambiri" zochokera ku IUCN.
