Zezinto eziphila emanzini. Ingwane. Incazelo, izici. Mingakhi imilente-octopus?

Octopus - omele lamabutho ka mollusk zasolwandle okuqondene ekilasini cephalopods. Ukuze zonke izinhlobo isici sacciform esifubeni. Kamuva esihlokweni siyathola izici lezi zilwane, njengoba i-octopus imilenze. Photo-shellfish Uyophinde unikezwe ngezansi.

incazelo emfushane

Izingwane izinhliziyo ezintathu. Main oludlula igazi ngomzimba. Labo abasele abanga-push it ngokusebenzisa zokuphefumula. Ngenxa yokuthi i-plasma bese erythrocyte hemocyanin samanje (indawo iron, ithusi) esikhundleni hemoglobin egazini izilwane okwesibhakabhaka. Thina octopus amehlo amakhulu nge umfundi elingunxande. ikhanda laso silwane is kahle, it has a skull cartilaginous. He biyela the ubuchopho kusukela cortex sombungu. usayizi isilwane - kusuka 50 mm kuya ku-9.8 m (phakathi imikhawulo feelers elise oppositely).

ukudla

Zonke izingwane - eziyingozi. ukudla yabo eziyinhloko ezinamagobolondo, inhlanzi, izimbaza. ingwane Common ithumba inyamazane ngayo yonke ihambe yayo. Bamba amaswidi somhlatshelo, eluma ke ngoqhwaku lwayo engezwa. ushevu kusukela nezindlala salivary uwela ekukhiqizeni isilonda. Ukuze i-octopus libhekene ukubonakaliswa izinto ngokombono womuntu siqu e ukudla nezindlela yokuthola yayo. Shellfish usenemigqa ezine ihambe. Indlela imilenze-octopus eziningi, futhi uma unalo uhlangothi, uzothola on.

Clams sendleleni

Izinhlobo eziningi bahlala yamadwala, izimila zasolwandle amatshe. Izintandokazi indawo yokucasha izilwane ezisencane eliseMpumalanga Ekude, isibonelo, kukhona amagobolondo ezingenalutho scallop. Ngenxa yokuthi izingwane ngaphezulu ezihamba ebusuku, basuke kubhekwe ebusuku. Ngakho, Mingaki imilente-octopus? Wakwenza kanjani ukusebenzisa ngezitho zakhe? Ngokusho ngokuqinile, kuhlanganise evele emaweni mollusk ukuhambisa ezinamaphiko ezihamba ngazo zozine. Ngesikhathi esifanayo kuhilela yonke ihambe. Abaningi bakholelwa ukuthi i-octopus imilenze ayisishiyagalombili. Nokho, lokho akulona iqiniso. Phakathi nocwaningo kwatholakala ukuthi odlulela Clam tentacles ezimbili. Ukuze siqhubekele phambili, usebenzisa lonke zomzimba. Movement "izandla" zifana ezenza ababhukudayo. Ipheya indluzelekazi esitho isetshenziswa ukuze uzule phansi kolwandle. Ngosizo lwabo, molluscum futhi ekhwela phezu kwamadwala kwamanzi. Ngakho, inani imilenze ingwane - 2, wonke amanye tentacles umsebenzi wezandla. Ngenxa yokuthi isidumbu mollusk nezimo, bakwazi ukungena ngokusebenzisa imifantu futhi ukuvuleka kabani Ubukhulu mancane kakhulu kunalawo bebodwa. Lokhu kubenza bakwazi ukufihla ezindaweni zokukhosela ehlukahlukene.

ukuziphatha

Ngo izinhlobo eziningi nezindlala ekhethekile ukukhiqiza ketshezi omnyama - "inki". Encwadini izindawo shapeless ayevumela kuthé namanzi futhi igcinwe isikhashana kuyinto compact, ngaphambi awusebenzi alulaze amanzi. Ukubalekela othile kokubaleka, ingwane inki ukhiqiza kwakuye kwancipha. Izazi kufanele usuku kungekho ukuvumelana mayelana nemigomo yalesi ukuziphatha. umcwaningi Cousteau hypothesized ukuthi "inki izindawo" e-octopus kukhona uhlobo Okuqondiwe zamanga ngabaphikisi, kukuphazamise ukunakwa yabo. Molluscs ube elinye ithuluzi ukuvikela. silwanyana izingalo zaso, wakuqonda okwakushiwo isitha kungavela off. Lokhu kungenxa imisipha eqinile. Esikhathini esithile izingalo zaso bathinteka liyaqhubeka lisabela ethintekayo ezishukumisa bese ukuhambisa. Kuyinto okwamanje i umdlalo ezengeziwe nalabo abanishushisayo ingwane.

umsebenzi ucwaningo

Kwaphela isikhathi eside kakhulu ukuthi angizange ngihlaselwe impendulo eqondile yalo mbuzo, imilenze eziningi kanjani-octopus. Izazi zezinto eziphilayo kufanele engaphezu kwamashumi amabili izikhungo European abathintekayo kulolu cwaningo eziphila olwandle, isikhathi eside ukubukela ukuziphatha izingwane. It ihlaziye kungathi izinkulungwane ezimbili idatha. Phakathi nocwaningo kwatholakala ukuthi ihambe ezimbili nakanjani ukukhahlela. Njengoba ojwayelekile, izilwane awasheshi. Kodwa uma clams ingozi ongafinyelela ngesivinini 15 km / h. Abacwaningi bathi ubuchopho kutshela ekuqaleni ukunyakaza, ukunquma ukuthi ijubane layo uma igijima, ubunjalo kanye isiqondiso antenna ngamunye kuthatha ngokuzimela. Nokho, ngisho nalabo nemilenze zazo ziklebhukile off emzimbeni, siqhubeke singenisa nezenzo zahlelwa ngaphambili. Izazi zezinto eziphilayo zithi nazo zatholakala ukuthi ngwane umyalo ezinhle lovakalako izitho zezikhulu izinhlangothi kwesokunxele bese kwesokudla umzimba. Nokho, okuthandayo namanje inikezwe eyesithathu phambi izingalo zaso - ke senzelwe isethulo emlonyeni ukudla. esitho ngasinye has 10 tysyach receptor kunqunywa okuyinto uphikisana ezidliwayo noma engenakudliwa ngobubi bawo.

Izici

Ukwazi kahle indlela izinyawo-octopus eziningi, futhi lisebenzisa ngezitho zakhe, abacwaningi wahlanganyela esifundweni intelligence isilwane. Zoopsychologists cabanga ngala mollusk ohlakaniphe kunazo zonke bonke abamele ezingenamgogodla. Lezi ziphetho zisekelwe kokuma esisebenzayo. Ngakho, cephalopods abe nenkumbulo enhle, aqeqeshwe, bakwazi ukuhlukanisa ngamajamo weJiyomethri: esikhulu kusukela encane, round isikwele, unxande mpo kusukela ovundlile. Ngaphezu kwalokho, ukujwayela abantu kalula ukuqaphela labo ukuwondla. Uma uchitha isikhathi esiningi nomuntu ingwane, kuyoba ezinokuthula. Lezi clams kahle sifundiseke.
