Ezilwandle, sithola inhlobonhlobo enkulu futhi emangalisayo engakafundwa. Kule nhlobonhlobo ekhangayo, sithola izilwane ezivela ku- i-octopoda oda, esaziwa kakhulu njengezingwane. Bavelele ekubukekeni kwabo okwehlukile futhi bakhuthaze izinganekwane eziningi nezindaba ngezilo zasolwandle. Ngakolunye uhlangothi, futhi bakhiqiza intshisekelo yesayensi ngokuhlukahluka abanakho.
Phakathi kwezici ezihlukile, sithola uhlelo lokujikeleza kwegazi lwama-octopus. Ekupheleni, i-octopus inezinhliziyo ezingaki? Eziningana noma eyodwa nje? Qhubeka ufunde le ndatshana yePeritoAnimal ukuphendula imibuzo yakho.
Lunjani uhlelo lokujikeleza kwegazi lwama-octopus?
Ama-cephalopods, okuyisigaba okukhona kuwo octopus, athathwa njengeqembu eliyinkimbinkimbi kakhulu lama-invertebrate, njengoba yize enezici ezifanayo nawo wonke ama-molluscs, aveza umehluko omkhulu obabeka ebangeni elihlukile. Inqubo yokuziphendukela kwemvelo yanikeza lezi zilwane ngezici ezithile ezizenza zibe iqembu elincintisana kakhulu ezindaweni eziphila olwandle.
Yize kukhona i-pigment engasebenzi kahle ekusebenziseni umoya-mpilo, ngenxa yamasu ahlukahlukene wokuguquguquka, bayakwazi ukuhlala kusukela olwandle kuya ezindaweni eziseduze komhlaba. Nabo futhi ababhukudi abahle kakhulu, banezinhlelo ezibalulekile zokuvikela nokuhlasela, kepha, ngaphezu kwalokho, bangabazingeli abahle kakhulu.
Zonke lezi zinzuzo bezingenakuthuthukiswa ngaphandle kobukhona bohlelo lokujikeleza kwegazi olunikezwe amakhono amahle kakhulu. Ngezansi, sichaza ukuthi hlobo luni lwama-octopus wokujikeleza kwegazi analo:
- isimiso sokujikeleza kwegazi esivaliwe: Uhlelo lokujikeleza kwegazi lwe-octopus luvaliwe, okusho ukuthi igazi elijikelezayo ligcinwa ngaphakathi kwemithambo yegazi.
- Imithambo yegazi enwebeka: Imithambo yegazi yakho iyaqina, njengaleyo yamagciwane omgogodla, futhi inesivumelwano.
- umfutho wegazi ophakemeUkushaya kwenhliziyo kukhiqiza ama-gradients abalulekile egazi, ngakho-ke lezi zilwane zinezinga lomfutho wegazi ophezulu. Lokhu kungenxa yokuthi banezinhliziyo ezingaphezu kweyodwa - sizochaza ukuthi zingaki izinhliziyo i-octopus enazo.
- Igazi eliluhlaza okwesibhakabhaka: Umbala wokuphefumula obhekele ukuthutha umoya-mpilo egazini yi-hemocyanin, eyenziwe ngethusi futhi inika igazi lalezi zilwane umbala oluhlaza okwesibhakabhaka. Lokhu kuncibilika kwi-plasma yegazi lama-octopus, hhayi amaseli awo.
- Ama-Gill anokusetshenziswa okuphezulu komoya-mpiloAma-octopus nama-cephalopods ngokuvamile anomthamo ophansi wokuthwala umoya-mpilo, isici esixazululwe ngokwakhiwa kwamagill anokusetshenziswa okuphezulu komoya-mpilo nezinye izindlela zokukhuthaza ukushintshaniswa kwegesi.
- Shintsha umthamo wegazi ezigulini zakho: banekhono lokushintsha ivolumu yegazi ezinyangeni zabo kuya ngezidingo zabo zomoya-mpilo nganoma yisiphi isikhathi.
- igazi elincane: banegazi le-viscous, ngoba yize okuqukethwe kwamanzi egazini kuphakeme, nokuqukethwe okuqinile.
Manje njengoba sesazi kabanzi ngohlelo lokujikeleza kwegazi, ake sibone ukuthi zingaki izinhliziyo i-octopus enazo nezizathu zalokho.
I-octopus inezinhliziyo ezingaki?
I-octopus inezinhliziyo ezi-3, ekubeni okukodwa okuyinhloko namabili okusekelayo. Okuyinhloko kubizwa ngenhliziyo ehlelekile noma emithanjeni kanti ezinye ezimbili yizinhliziyo ze-branchial. Manje ake sichaze umehluko phakathi komunye nomunye wabo.
Inhliziyo ehlelekile noma yegazi
Le nhliziyo yakhiwe i-ventricle, lapho kuxhunyaniswa khona imithambo yegazi, kanye nama-atria amabili athola igazi emithanjeni. Le nhliziyo iphampa igazi emzimbeni wonke futhi iyilungu elisabalalisa inani eliphakeme lezicubu zegazi ezidingwa yilezi zilwane.
izinhliziyo ze-gill
Izinhliziyo ezimbili ze-gill zincane futhi zisebenza njengamaphampu asizayo, zithumela igazi ezigulini, lapho kuzokwenzakala khona umoya-mpilo wegazi ukuze ukwazi ukusatshalaliswa kuwo wonke umzimba, ukuwuphefumula ngokuphelele.
Emfanekisweni olandelayo singabona ukuthi izinhliziyo ezi-3 ze-octopus zikuphi.
Kungani i-octopus inezinhliziyo ezi-3?
Yize unezici eziningana ezibenza babe yizilwane ezisezingeni eliphakeme kakhulu, octopus banezici ezithile ezingathandeki zezinhlobo zabo. Izici ezinjalo zibenze bakwazi ukuzivumelanisa noma ukuguquguquka ukwenza ngcono ukusinda kwabo esikhathini esifushane abavame ukuba naso (i-octopus iphila phakathi kweminyaka emithathu kuya kwemihlanu ngokwesilinganiso, kuye ngohlobo). Kulezi zimo, ukuba khona kwezinhliziyo ezintathu ku-octopus kudlala indima ebalulekile. Ngakolunye uhlangothi, ukukwazi ukwandisa noma ukunciphisa ivolumu yegazi labo kuyabasiza ikakhulukazi lapho bezingela inyamazane noma bebalekela umhlaseli.
Ngakolunye uhlangothi, octopus ngokuvamile bathanda olwandle, imvamisa i-oxygen engenayo. Kodwa-ke, imishayo yabo isebenza kahle kakhulu ekumungeni okungaba khona i-oxygen encane, ngisho nangaphezu kwezinhlanzi, okubavumela ukuthi bakwazi ukufinyelela ezilwaneni ezinye izilwane zasolwandle ezingafinyeleli kuzo.
Kukho konke lokhu, kufanele sengeze ukuthi izilwane zasemanzini zikhonjelwe ku- ingcindezi enkulu kunalezo ezihlala ezindaweni eziphila emhlabeni.
Iqiniso lokuthi i-octopus inezinhliziyo ezi-3 lenza umzimba wayo uvumelane kahle ne- Imvelo yasolwandle futhi ingaphila njengenhlobo.
Yize o-octopus kungezona kuphela izilwane ezinenhliziyo engaphezu kweyodwa, ziheha ukunakekelwa ngenxa yesimo sazo esiyingqayizivele, kepha futhi ngoba izifundo zesayensi zibonisa ubuningi obengeziwe bezilwane, phakathi kwazo okuvelele ubuhlakani.
Ngabe i-octopus inezintambo ezingaki?
Manje njengoba usazi ukuthi zingaki izinhliziyo i-octopus enazo, ungahle uzibuze ukuthi mangaki ama-tentacles i-octopus. Impendulo ithi unamatende ayisishiyagalombili.
Kulezi zinguquko eziyisishiyagalombili izinkomishi zokudonsa ezinamandla nezinamandla, ezisetshenziselwa i-octopus ukunamathela kunoma iyiphi indawo.
Ake sazi ezinye izici zama-octopus:
- I-octopus ingakushintsha ukubukeka kwayo, njengoba kwenza onogwaja, kanye nokuthungwa kwayo, kuya ngemvelo noma izidalwa ezikhona.
- uyakwazi vuselela amatende akho uma benqunywa.
- Izingalo ze-octopus ziguquguquka ngokweqile futhi zinokunyakaza okungapheli. Ukuqinisekisa ukulawula okufanele, uhamba esebenzisa amaphethini abekwe eceleni anciphisa inkululeko yakhe futhi avumele ukulawula okukhulu komzimba wakhe.
- Itende ngalinye ku-octopus linamakhemikhali amakhemikhali angaba yizigidi ezingama-40, ngakho-ke umuntu ngamunye kucatshangwa ukuthi uyisitho esikhulu sezinzwa.
- Kukhona ubudlelwane phakathi kwama-olfactory receptors ebuchosheni be-octopus kanye ne- uhlelo lokuzala. Bayakwazi ukukhomba izakhi zamakhemikhali ezintanta emanzini ezinye izingwane, ngisho nangezinkomishi zabo zokudonsa.
Futhi ngenkathi sikhuluma ngezinhliziyo nokuqina kwe-octopus, ungahle ube nentshisekelo kule vidiyo ngezilwane eziyisikhombisa zasolwandle eziyivelakancane emhlabeni:
Uma ufuna ukufunda izindatshana eziningi ezifana ne- I-octopus inezinhliziyo ezingaki?, sincoma ukuthi ufake isigaba sethu se-Curiosities somhlaba wezilwane.
