Inhlanzi yolwandle: incazelo, indawo yokuhlala kanye namaqiniso athakazelisayo

Umuntu wanikeza igama labo abahlala olwandle, abaqondiswa yizinqubo ezingavamile. Ngokuvamile amagama asetshenziselwa izilwane zasemhlabeni ezinenani elifanayo elikude noma imikhuba efanayo. Ngakho-ke, abadobi bezilwandle babizwa ngokuthi i- manatee inkabi yezilwandle ngenxa yobukhulu obukhulu nokubukeka okubonakalayo. Futhi igama le-fox yolwandle lalisungulwa masinyane emva kwabameleli abaningana abajulile.

Isidakamizwa esiyingozi

Emanzini asePacific naseNdiya, kukhona shark enkulu - fox shark. Ubude bayo obude bufinyelela kumamitha ayisithupha, futhi isisindo - cishe 400 kg. Igama elivame kakhulu lalo hlobo lwenhlanzi, njengoba kungenzeka ukuthi ucabange, yi-fox yolwandle. Ushaka waluthola ngenxa yomsila omude, futhi ukuba uqondisise, ingxenye ephezulu ye-caudal fin. Le divayisi isisiza izilwane ukuba zithole ukudla. Futhi lokhu kwenzeka kanjani, ake sizame ukuchaza ngokuningiliziwe.

Indlela ushaka, obizwa ngokuthi i-fox yolwandle, uzingela

Inhlanzi yolwandle ayifuni ukuhlasela impi ngokuqondile. Isebenzisa ukuzingela i-flexible part of the caudal fin. Ukuthola umhlambi wezinhlanzi, isidumbu siphumelela ngokushesha bese siqala ukusikhipha umsila. Izinhlayiya zokuphela ziphoqa inyamazane, futhi udoki ungadla kuphela izinhlanzi.

Omunye noma ngaphezulu?

Ama-Sharks ane-end-caudal fin efana neyodwa, kodwa ahlukaniswe abe izinhlobo ezintathu:

• I- fox yase- Sea ivamile.
• Fox ojulile olwandle (shark omkhulu-eyed).
• I-shark e-Pelagic evela enhlobonhlobo yezimpungushe.

Ubude be-caudal fin yelungu ngalinye laleli gciwane lingaphezulu kwengxenye yobude bomzimba wayo. Umuntu kungenzeka ukuthi angabhekana nesilwane esijulile sezilwandle. Imikhuba yakhe ayiqondakali kahle, kodwa abafakazi bokuzibonela balezi zingxoxo ezingavamile basitshela ukuthi umsila onamandla oshaywayo lapho izinhlanzi ezibangelwa khona lapho bephezu kwe-schooner yokudoba kwabangela umonakalo omkhulu futhi balimaza abadobi.

I-pelagic fox shark nayo ivela njalo. Ngenxa yobuningi bemikhuba yokuzingela, inyamazane ihlwanyelwa ikakhulukazi ekudobeni ukudoba hhayi emlonyeni, kodwa nge-final caudal.

I-common fox fox evamile. Inezindawo ezahlukene zokuhlala - ezivela ezindaweni ezishisayo eziseNorway. Le nhlanzi yinkulu kunazo zonke izimpungushe. Ingakhula ibe ngamamitha ayisithupha.

Umbala wezinhlobonhlobo ezihlukahlukene uhluka kusuka ebomvu-brown kuze kube mnyama-grey. Ngezinye izikhathi inhlanzi ingabhakabhaka. Ingemuva ihlale imnyama kunesisu. Izinhlanzi ze-Ventral kanye ne-pectoral zezinhlanzi zasolwandle zingaba nezindawo ezimhlophe.

Imikhiqizo ye-Long-tailed Predator

I-Fox ibhekisela ku-sharks viviparous. Enye insikazi ayinabantwana abangaphezu kwamabili ngesikhathi esisodwa. Yize kunzima ukubiza ingane ukuthi i-fox fox. Ubude bayo ekuzalweni buyizingalo ezilodwa nengxenye. Ngesikhathi sokukhulelwa, "izinsana" zikhula zibe ngamamitha amane.

Isikhathi esidala sokuqala

Ngokuvamile, oshaka yizinhlobo zasendulo zezinhlanzi zasendulo. Ososayensi bakholelwa ukuthi eminyakeni eyizigidi ezingu-400 edlule, lezi zilwane ezidliwayo sezizingele kakade olwandle olujulile. Leli qiniso lingakwazi ukuchaza isakhiwo esithile esiyinkimbinkimbi soshaki. Okokuqala, lezi zinhlobo zingokwezinhlanzi ze- cartilaginous, okungukuthi, abanalo izicubu zethambo. Futhi oshaka abanalo isembozo segill. Kodwa-ke, izilwane zasendulo zizizwa zizizwa kahle ezweni lanamuhla futhi azikho ngaphansi kwezilwane "ezincane" ezengeziwe.

Esinye isilwane siyindawo

Igama le-fox yolwandle lalihlelwe ngumuntu oyedwa omele umhlaba ongaphansi kwamanzi. Ngakho-ke abiza ama-thorny (prickly). Lena inhlanzi ephansi yesimo esingavamile. Lihlala e-Atlantic Ocean, eMedithera naseLwandle oluMnyama.

Isilwane esithakazelisayo , i- fox yolwandle , sinomzimba we-rhomboid we-flat kanye nomsila omude omude. Kubantu abaningi, ubude bomsila bulingana nobude bomzimba. Ingemuva nengxenye engenhla yomsila womuntu omdala oyinhloko ye-stingray inomugqa wameva. Enombolweni yabo kungaba khona izingcezu ezingamashumi amathathu nambili. Umsila uphela ngamaphethini amabili amancane. I-fox yolwandle inenhloko emfushane, futhi umzimba wayo, naphezu kokuthi akuyona nxazonke, ubizwa ngokuthi i-disc.

Ezinye izici ze-skates

Iningi lezinkathi ze-skates zasolwandle zichitha, lifakwe emhlabathini odaka noma onesihlabathi. Ukujula okuthandayo kuvela kumamitha angamashumi amabili kuya kwamakhulu amathathu, kodwa kube khona amacala okuthola abamele ngabanye ngokujula kwama-550 m.

Lezi zinhlobo zibhekisela emisebeni ye-rhombus futhi, njengenhlanzi yeshaka, emndenini wezinhlanzi ezinama-cartilaginous. Idla ngezibungu, izibungu, ama-mollusks amancane, konke okubizwa ngokuthi igama elilodwa - i-benthos. Ngezinye izikhathi ekudleni kwabantu abadala kukhona ama-crustaceans nezinhlanzi ezincane.

Ubukhulu bezimpungushe zesilisa buyingcosana, ayikho ngaphezu kuka-70 cm. Insikazi inkulu kakhulu. Abanye abantu bakhula kuya ku-120 cm.

Ukukhiqiza

I-scat iyinhlanzi yasolwandle ikhuluma ngezinhlobo zamaqanda ezizala amaqanda, okungukuthi, imibungu ivela ngaphandle komzimba kamama. Ukuhluma entwasahlobo, kubhekwa ukukhulelwa kwangaphakathi. Ngemva kwalokho, owesifazane ubeka amaqanda amasonto ambalwa. Le nqubo yansuku zonke iletha amaqanda ama-50-150 ngesizini. Amagayi endlela avikelwe yi-capsule enesisindo ehambisana nezinqubo ezikhethekile ze-lateral. Zifana nezintambo ezinamathiselwe ku-algae, zibambe iqanda endaweni.

Amaqabunga amaqanda avela emva kwezinyanga ezingu-5. Izitshalo ezincane ziba nobude obuyi-12-13 cm. Izinsana zokudla zikhishwa ngokuzimela, ngokuvamile ziba yinto yokudla izinhlanzi ezinkulu . Ukuphila okuvamile kwesiteji kuyinhlanzi yasolwandle - iminyaka engu-15-17. Ukuvuthwa ngokocansi kwamadoda nabesifazane kufinyelela cishe ngonyaka wesishiyagalombili wokuphila.

Izimpondo ze-Pectoral ezimpungushe zasolwandle (oshaka kanye nemisebe)

Kuyathakazelisa ukucabangela ukuhlukana okuyisisekelo phakathi koshaki nemisebe enegama elifanayo. I-fox shark ifana ne-torpedo ephilayo egijimela elwandle. I-foxy fox ifana neqabunga elikhulu, elihamba ngezinyathelo ezinjenge-waves. Ukuma komzimba woshaki nemisebe kubangelwe ukuguquguquka kwezilwane, njengoba behamba ngendlela ehlukile yokuphila.

Amaphiko e-pectoral we fox ahlukile. Umsebenzi wabo uncike kunhlobo yezinhlanzi:

• Izinhlayiya ze-pectoral zohlu lwezilwane zasolwandle zikhonza ukuzinza komzimba. Awuvumeli isidumbu siwele eceleni. Futhi lolu uhlobo "lwezintambo zokuphakama."
• Ku-stingray ye-fox yase-marine, amaphesenti e-pectoral aklanyelwe ukuhlela. Unamaphethelo ajwayelekile ngokungavamile ahlangane nama-lateral okubonakalayo emzimbeni nasenhloko.

Ngakho-ke, ngenxa yobungqayizivele besakhiwo se-pectoral fins, u-shark wakwazi ukugijima masinyane futhi asebenze ngentshiseko ngesikhathi sokuzingela. I-stingray i-fox yolwandle ingahamba ngokushelela futhi ithule emakholomu amanzi, iqoqe ifolishi layo elincane.

Eqinisweni, ama-skates kanye noshaki basondelene nabo. Zombili lezi zinhlobo zisezinhlanzi zasendulo ezinamabala. Kodwa-ke, ukuziphendukela kwemvelo kancane kancane kwashintsha isakhiwo samagceke ayo, futhi namuhla kunzima ukukholelwa ekuzibophezelaneni okunjalo.
