Zamkati

Akamba am'nyanja (Chelonoidea superfamily) ndi gulu la zokwawa zomwe zasintha kukhala m'nyanja. Pachifukwa ichi, monga tionera, ali ndi mawonekedwe angapo omwe amawalola kuti azisambira nthawi yayitali kwambiri yomwe imapangitsa kuti moyo wamadzi ukhale wosavuta.

THE Kudyetsa kamba zimatengera mtundu uliwonse wa zamoyo, madera omwe amakhala komanso kusamuka kwawo. Mukufuna kudziwa zambiri? Munkhaniyi ndi PeritoAnimal timayankha mafunso anu onse okhudza zomwe akamba a m'nyanja amadya.

Kamba wam'nyanja

Tisanadziwe zomwe akamba am'madzi amadya, tiyeni tiwadziwe bwino. Pachifukwa ichi, tiyenera kudziwa kuti banja labwino kwambiri la chelonian limangophatikiza Mitundu 7 padziko lonse lapansi. Onse ali ndi zinthu zingapo zodziwika:


  • carapace: Akamba amakhala ndi chipolopolo cha mafupa chopangidwa ndi nthiti komanso gawo lina la msana. Ili ndi magawo awiri, backrest (dorsal) ndi plastron (ventral) yomwe imalumikizidwa pambuyo pake.
  • zipsepse: Mosiyana ndi akamba amtunda, akamba am'nyanja ali ndi zipsepse m'malo mwa mapazi ndipo matupi awo amapangika bwino chifukwa chokhala nthawi yayitali akusambira.
  • Chikhalidwe: akamba am'madzi amagawidwa kwambiri m'nyanja ndi m'nyanja zotentha. Zili pafupifupi nyama zonse zam'madzi zomwe zimakhala munyanja. Ndi akazi okha amene amaponda pamtunda kuti aikire mazira pagombe pomwe adabadwira.
  • Mayendedwe amoyo: moyo wa akamba am'nyanja umayamba ndikubadwa kwa ana obadwa kumene pagombe ndikuyamba kwawo kunyanja. Kupatula kamba wam'madzi waku Australia (Kukhumudwa kwa Natator), akamba achichepere amakhala ndi gawo loyera lomwe nthawi zambiri limaposa zaka 5. Pazaka zonsezi, amafika pokhwima ndikuyamba kusamuka.
  • Kusamuka: Akamba am'nyanja amasuntha kwakukulu pakati pa malo odyetserako ziweto ndi malo osakanizirana. Zazikazi, zimapitanso ku magombe komwe adabadwira kuti akaikire mazira, ngakhale nthawi zambiri amakhala pafupi ndi malo okwanira.
  • Zizindikiro: monga nyama zambiri zam'madzi, akamba amakhala ndi chidwi chamakutu. Kuphatikiza apo, moyo wawo watukuka kuposa moyo wa akamba amtunda. Chodziwikanso ndichakuti amatha kuchita bwino nthawi yakusamuka.
  • kutsimikiza kugonana: kutentha kwa mchenga kumatsimikizira kugonana kwa anapiye akakhala mkati mwa dzira. Chifukwa chake, kutentha kukakwera, akazi amakula, pomwe kutentha kumakulitsa kukula kwa akamba amphongo.
  • Zopseza: akamba onse am'nyanja kupatula kamba wam'madzi waku Australia (Matenda a Natator) akuwopsezedwa padziko lonse lapansi. Hawksbill ndi Kemp Turtle zili pachiwopsezo chachikulu choti zitha. Zowopsa zazikuluzikulu za nyama zam'madzi izi ndi kuipitsidwa kwa nyanja, kukhalapo kwa magombe, kugwidwa mwangozi ndikuwonongedwa kwa malo awo chifukwa cha ma trawling.

Mitundu yodyetsa akamba am'madzi

Akamba alibe mano, Gwiritsani ntchito m'mbali mwa mkamwa mwawo kudula chakudya. Chifukwa chake, kudyetsa akamba am'nyanja kumadalira zomera ndi zamoyo zopanda madzi.


Komabe, yankho la zomwe kamba amadya sizophweka chonchi, popeza akamba onse am'nyanja samadya zomwezo. Titha kusiyanitsa mitundu itatu ya akamba a m'nyanja kutengera zakudya zanu:

  • odyetsa nyama
  • Zomera zodyera
  • omnivorous

Kodi akamba akudya zam'madzi amadya chiyani

Mwambiri, akamba awa amadya mitundu yonse ya zamoyo zam'madzi, monga zooplankton, sponges, jellyfish, crustacean molluscs, echinoderms ndi polychaetes.

Izi ndi akamba akudya ndi nyama zawo:


  • Kamba wachikopa (Dermochelys coriacea): ndi Kamba wamkulu padziko lonse lapansi ndipo kumbuyo kwake kumatha kufikira masentimita 220 m'lifupi. Zakudya zawo zimapangidwa ndi Scyphozoa ndi zooplankton jellyfish.
  • Fulu la Kemp(Lepidochelys Kempii): Kamba aka amakhala pafupi ndi msana wake ndipo amadya mitundu yonse ya nyama zopanda mafupa. Nthawi zina, imathanso kudya ndere zina.
  • Kamba wam'madzi waku Australia (Kukhumudwa kwa Natator): ndizofala ku alumali aku Australia ndipo, ngakhale ali odyera okha, amathanso kudya ndere zochepa.

Ngati mukufuna kudziwa zambiri za kudyetsa nyama zazikulu zam'nyanja, musaphonye nkhani ina iyi yokhudza zomwe namgumi amadya.

Zomwe Akamba Akale Odyera Kudya Amadya

Akamba odyetserako zamoyo amakhala ndi mlomo wonyezimira womwe umawalola kuti azidula mbewu zomwe amadyazo. Mwachidziwikire, amadya ndere ndi zomera zam'madzi monga Zostera ndi Oceanic Posidonia.

Pali mtundu umodzi wokha wa kamba wam'madzi wokometsera, the kamba wobiriwira(Chelonia mydas). Komabe, izi Kamba wam'nyanja akuwonongeka kapena achichepere amadya zopanda mafinya, ndiye kuti, munthawi imeneyi amakhala omnivorous. Kusiyanasiyana kwa zakudya m'thupi kungakhale chifukwa cha kuchuluka kwa mapuloteni pakukula.

Zomwe akamba am'madzi omnivorous amadya

Akamba am'madzi am'madzi amadya nyama zopanda mafupa, zomera ndi nsomba zina amene amakhala pansi pa nyanja. Mu gululi titha kuphatikiza mitundu yotsatirayi:

  • kamba wamba(alireza): kamba uyu amadyetsa mitundu yonse ya nyama zopanda mafupa, algae, phanerogams zam'madzi ndipo amadya nsomba zina.
  • kamba wa azitona(Lepidchelys olivacea): ndi kamba yomwe imapezeka m'madzi otentha komanso otentha. Zakudya zanu zimasiyanasiyana kutengera komwe muli.
  • Kamba wa Hawksbill (Eretmochelys imbricata): Achinyamata a kamba wam'nyanjayi amakonda kudya. Komabe, achikulire amaphatikiza ndere pazakudya zawo zabwinobwino, chifukwa chake atha kudziona ngati omnivorous.

Ngati mukufuna kuwerenga zina zambiri zofanana ndi Kodi akamba a m'nyanja amadya chiyani?, Tikukulimbikitsani kuti mulowe gawo lathu la Zakudya Zoyenera.
