Yimaphi amaphiko asiza izinhlanzi ukuthi ziye phambili?

Isingeniso: Ukuqonda Izinhlanzi Zezinhlanzi

Amaphiko ezinhlanzi ama-appendages aphuma emzimbeni wenhlanzi futhi asetshenziselwa ukunyakaza nokuzinza emanzini. Lezi zimpiko zidlala indima ebalulekile ezimpilweni zezinhlanzi, zizisiza ekubhukudeni, ekuqondiseni nasekugcineni ibhalansi ngenkathi zihamba emanzini. Ukuma nobukhulu bamaphiko ezinhlanzi kungahluka kuye ngezinhlobo zabo, indawo yokuhlala kanye nendlela yokuphila.

Ukubaluleka Kwezimpondo Zezinhlanzi Ekubhukudeni

Amaphiko ezinhlanzi abalulekile ekubhukudeni. Zivumela izinhlanzi ukuba zihambe emanzini ngokunikeza ukuhamba, ukuqondisa, nokuzinza. Ngaphandle kwamaphiko, izinhlanzi bezingeke zikwazi ukubhukuda ngokuphumelelayo, futhi amathuba azo okuphila endaweni yazo yemvelo azoncipha kakhulu. Izinhlanzi ezinamaphiko angakakhuli kahle zingase zikuthole kuyinselele ukubamba inyamazane, ukubalekela izilwane ezidla ezinye, noma ukuthuthela ezindaweni ezintsha.

Uhlolojikelele lwezinhlobo zama Fins

Izinhlanzi zinezinhlobo ezinhlanu ezihlukene zamaphiko: amaphiko e-caudal, amaphiko angemuva, ama-anal fins, ama-pelvic fins, nama-pectoral fins. Uhlobo ngalunye lwamaphiko lunomsebenzi othile, futhi ukuma kwawo nobukhulu kuyahlukahluka kuye ngezinhlobo zezinhlanzi, indlela yokuphila, nendawo yokuhlala.

Iziphetho Eziphezulu Zokuhamba Phambili

I-Caudal, i-pectoral, ne-anal fins amaphiko aphezulu okuya phambili. Lezi zimpiko zinomthwalo wemfanelo wokukhiqiza i-thrust kanye nokudonsa izinhlanzi emanzini. Nakuba izimpiko zomhlane zingase zibe nomthelela ekuhambeni phambili, umsebenzi wazo oyinhloko uwukunikeza ukuzinza nokuvimbela izinhlanzi ukuba zingagingqiki.

Ama-Caudal Fins kanye Neqhaza Lawo Ku-Propulsion

I-Caudal fins, eyaziwa nangokuthi i-tail fins, ingenye yamaphiko abaluleke kakhulu ekuqhubekiseni izinhlanzi. Zisetshenziselwa ukusunduza amanzi ngemuva kwezinhlanzi, ziwaqhubele phambili. Ukuma nobukhulu be-caudal fin kuyahlukahluka kuye ngokuthi hlobo luni lwezinhlanzi, ezinye izinhlanzi ezinomsila owenziwe ngemfoloko, kanti ezinye zinomsila oyindilinga noma ocijile.

I-Pectoral Fins kanye Negalelo Lazo Ekuqhubekiseni Phambili

Amaphiko e-Pectoral atholakala nhlangothi zombili zomzimba wenhlanzi futhi asetshenziselwa ukuqondisa, ukumisa, nokudonsa izinhlanzi emanzini. Zibaluleke kakhulu ezinhlanzini ezibhukuda eduze naphansi noma ezindaweni ezinemisinga enamandla lapho zidinga khona ukugcina ukuzinza. I-Pectoral fins ikhiqiza i-lift kanye nokuphonsela phambili, okuvumela izinhlanzi ukuthi zibhukude kahle.

I-Dorsal Fins: Ingabe Zisiza Izinhlanzi Ukuqhubekela Phambili?

Amaphiko e-Dorsal atholakala phezulu emzimbeni wezinhlanzi futhi asetshenziselwa ngokuyinhloko ukuzinza nokulinganisela. Nakuba zingasiza izinhlanzi ukuthi ziqhubekele phambili, umsebenzi wazo oyinhloko ukuvimbela izinhlanzi ukuba zingagingqiki. Ezinye izinhlanzi, njengoshaka, zingase zisebenzise amaphiko azo angemuva ukuze zinciphise ukudonsa nokwandisa isivinini sazo.

I-Anal Fins: Isici Esibalulekile Sokuhamba Phambili

Amaphiko ezindunu atholakala ngaphansi komzimba wenhlanzi futhi asetshenziselwa ukusimamisa izinhlanzi njengoba ibhukuda. Ziphinde zinikeze ukuphakamisa nokugxila phambili, okufaka isandla ekuqhubekiseni izinhlanzi emanzini.

Indlela Izinhlanzi Ezisebenzisa Ngayo Amaphiko Ukuze Ziqhubekele Phambili

Izinhlanzi zisebenzisa amaphiko azo ukuqhubekela phambili ngokwenza ukusunduza nokuziqhubela emanzini. Amaphiko asebenza ndawonye ukuze anikeze ukuphakama, ukuzinza, kanye nendlela, okwenza izinhlanzi zibhukude kahle. Inhlanzi ingase futhi ilungise i-engeli nendawo yamaphiko azo ukuze ishintshe indlela noma isivinini.

Izici Ezithinta Ukuhamba Kwezinhlanzi Phambili

Kunezici eziningana ezingathinta ukuhamba phambili kwenhlanzi, okuhlanganisa ubukhulu nokuma kwamaphiko ayo, izinga lokushisa kwamanzi, ukuminyana kwamanzi, nesisindo somzimba wenhlanzi. Izinhlanzi ezisinda kakhulu noma ezinamaphiko angakakhuli kahle zingase zibe nzima ukubhukuda ngendlela efanele, kuyilapho izinhlanzi ezinemizimba eqondile kanye nezimpiko ezinamandla zijwayele ukubhukuda amabanga amade.

Isiphetho: Iziphetho Ezinhle Kakhulu Zokubhukuda Okuphumelelayo

I-Caudal, pectoral, ne-anal fins amaphiko angcono kakhulu okubhukuda okuphumelelayo. Lezi zimpiko zisebenza ndawonye ukuze zikwazi ukushukuma, ukuzinza, nokuqondisa, okwenza izinhlanzi zibhukude ngokuphumelelayo emanzini. Kodwa-ke, ubukhulu kanye nokuma kwamaphiko kungahluka kuye ngokuthi uhlobo lwezinhlanzi, indawo yokuhlala, nendlela yokuphila.

Izincomo Zokukhetha Amaphiko Ezilwane Zasemanzini

Lapho ukhetha amaphiko ezilwane zasemanzini, kubalulekile ukucabangela uhlobo lwesilwane, ubukhulu, nendawo yokuhlala. Isibonelo, izinhlanzi ezibhukuda eduze naphansi zingase zidinge izimpiko ze-pectoral ezinkulu ukuze zizinze, kuyilapho izinhlanzi ezibhukuda emanzini avulekile zingazuza kumzimba oqondile kanye ne-caudal fin enamandla ukuze iqhutshwe. Ukukhetha amaphiko afanele kungasiza izilwane zasemanzini zibhukude kahle nangokunethezeka endaweni yazo yemvelo.
