Eziphila elwandle. Ngwane. Inkcazelo, iimpawu. Mingaphi imilenze octopus?

Ngwane - mmeli iqembu izilwanyana zolwandle ukubayinxalenye udidi izilwanyana. Ngokuba zonke iintlobo uphawu sacciform umntla. Kamva kweli nqaku sifumanisa iimpawu zezi zilwanyana, njengoko ngwane imilenze. Kwakhona Photo saselwandle esineqokobhe ziya kunikwa ngezantsi.

ingcaciso emfutshane

Octopuses iintliziyo ezintathu. Main lweqela igazi ngomzimba. Esiseleyo akathi ngokusebenzisa iigilizi. Ngenxa yokuba plasma kunye erythrocytes langoku hemocyanin (indawo intsimbi, ubhedu) endaweni yetekisi egazini lezilwanyana eluhlaza. Thina ngwane amehlo elikhulu umfundi yoxande. Siqulunqwa intloko silwanyana kakuhle, iye yokakayi cartilaginous. Uyabakhusela ubuchopho ukusuka uthinte osandul. ubukhulu isilwanyana - ukususela-50 mm ukuya 9.8 m (phakathi iziphelo okuva akhiwe oppositely).

ukudla

Zonke octopuses - ngamarhamncwa. ukudla ezona intlanzi, intlanzi, isilwanyana. ngwane Common idlulisela ixhoba kunye nemisipha yawo. Bamba idini lana, yena iluma oko ngomlomo wayo. ityhefu evela kwamadlala amathe owayo inxeba kwimveliso. Kuba ngwane luphawulwa amazwi kukhetho ngamnye ukutya kunye neendlela zokufumana kwayo. Yesilwanyana saselwandle esineqokobhe uye izibini ezine nemisipha. Ukuba isandla, uya kufumana phezu Mingaphi imilenze octopus, kunye.

Squid ethutha

iintlobo ezininzi abahlala phakathi kwamatye, nokhula lwaselwandle kunye namatye. sifihla Favorite indawo izilwanyana ulutsha kwiMpuma Ekude, umzekelo, aba kweqokobhe engenanto ye scallops. Ngenxa yokuba octopuses banento ngakumbi ebusuku, ziyashukuxwa zasebusuku. Ngoko ke, zingaphi imilenze octopus? Njani ukuba asebenzise nemilenze yakhe? Ngokutsho ngokuqinileyo, kuquka iindawo amqengqelezi mbambela ukuhamba ngazitho zine. Ngelo xesha nye ababandakanyekayo zonke nemisipha. Abantu abaninzi bakholelwa ukuba ngwane imilenze ezisibhozo. Noko ke, oku akuyonyaniso. Ngethuba lokwenza uphando kwafunyaniswa ukuba ugqithayo Clam Mpondwana ezimbini. Ukuya phambili, usebenzisa ezinye mlenze. Movement "izandla" ziyafana abo benza ezinekhono. A pair lomzimba nemazi isetyenziswa kokulawula ngapha emgangathweni wolwandle. Ngoncedo lwabo, molluscum kwakhona akhwele ematyeni kwamanzi. Ngenxa yoko, inani imilenze octopus - 2, onke amanye Mpondwana kufuneka umsebenzi wezandla. Ngenxa yokuba umzimba izilwanyana bhetyebhetye, babe kusichukumisa ziqhekeza kunye iminyango zabo bungu zincinane kakhulu zabo. Oku kwenza ukuba kuzimela kwimikhukhu ezahlukeneyo.

ukuziphatha

Kwiintlobo ezininzi kufuneka amadlala ezikhethekileyo avelisa engamanzi emnyama - "inki". In a amabala shapeless kwawo oxhonywe emanzini elulwelo waza waqhubeka kangangexesha elithile Ngokomzi, phambi kokuba akukho yaze yangxenga ifuthe lomanyano emanzini. Ekubalekeleni umntu ebalekayo, ngwane inki uvelisa kuthotha. Izazi ukuba umhla akukho ukuvumelana malunga neenjongo yalo yokuziphatha. Cousteau umphengululi hypothesized ukuba "iindawo inki" kwi ngwane i uhlobo ekujoliswe zobuxoki ngabaphikisi, imisindo ingqalelo yabo. Molluscs nesinye isixhobo ukukhusela. silwanyana Tentacle, wayiqonda utshaba yehla. Oku kungenxa ucutheko eyomeleleyo kwezihlunu. Abanye tentacle ihlukane ixesha iyaqhubeka ukuphendula selungu lokuva ezintweni kunye nesihamba ngayo. Kuyinto kodwa utshintsho eyongezelelweyo abo banitshutshisayo ngwane.

umsebenzi wophando

Kangangexesha elide kakhulu ke akazange abe impendulo ngqo lo mbuzo, imilenze emininzi njani ngwane. Izazi amaziko yaseYurophu ngaphezu amabini inxaxheba kuphononongo ubomi elwandle, kuba ixesha elide ubukele ukuziphatha octopuses. Oku lahlaziya malunga namawaka amabini data. Ngethuba lokwenza uphando kwafunyaniswa ukuba Mpondwana ababini ngokuqinisekileyo ukukhahlela. Njengomthetho jikelele, izilwanyana ukuhamba kancinane. Kodwa kwimeko squid ingozi unako ukufikelela ngesantya-15 km / h. Abaphandi bathi ukuba ubuchopho uthumela uphawu ekuqaleni intshukumo, isigqibo sokuba isantya wayo, ubume kunye nolwalathiso thwanga ngamnye kuthatha ngokuzimeleyo. Noko ke, kwanabo amalungu omzimba apho yaphulwa ukusuka umzimba, qhubeka ukuthatha amanyathelo ukuba ehlelwe ngaphambili. Izazi iye kwafunyanwa ukuba ngwane umyalelo zolunga na imilenze ze kumacala asekhohlo nasekunene umzimba. Noko ke, kukhethwa nangoku yanikwa tentacle wesithathu ngaphambili - senzelwe azandlale umlomo ukutya. omzimba ngalinye ukuya ku-10 receptors tysyach ugqibe ngayo bengavumi ezityiwayo okanye ngobubi bawo.

iimpawu

Ukwazi isebenzisa kakuhle zingaphi iinyawo octopus, kunye nemilenze yakhe, abaphengululi inxaxheba kuphononongo sezobuntlola yezilwanyana. Zoopsychologists ingqalelo ezi izilwanyana kakhulu okrelekrele abameli zonke ezingenamqolo. Ezi izigqibo zisekelwe zokubonakala aluncedo. Ngoko ke, izilwanyana inkumbulo elungileyo, ukuba baqeqeshwe, uyakwazi ukwahlula iimilo zejiyometri: ezinkulu ukususela kwabancinane, ngeenxa isikwere, uxande nkqo ukusuka tye. Ukongeza, ukuba siqhelane kubantu ngokulula nibazi luphe into etyiwayo. Ukuba uchitha ixesha elininzi kunye octopus, kuya kuba mbuna. Ezi squid ngokugqibeleleyo okufundisa.
