I-lateral line of izinhlanzi kanye yendima yayo ekuqhubeleni ukuziphatha nokuphila zezinhlanzi

Izinzwa zinendima ebaluleke kakhulu ekuphileni futhi ukuziphatha izinhlanzi. Fish, njengabanye ezilwaneni ezinomgogodla, abe isethi ephelele ehlanganisa izinzwa ezinhlanu. Kodwa babe i umehluko obalulekile - i-lateral line. Inhlanzi lesi sitho sezinzwa ngokuthi lesithupha. Izilwane ezihlala ezweni ngokuhamba kwemvelo baye balahlekelwa kube sixth sense, kodwa wasala Waterfowl futhi kunalokho kusiza ezimpilweni zabo, kuyasiza ukusinda udle.

Anatomy of inhlanzi. izinzwa

Omunye main izinzwa e izinhlanzi abhekwa lokuhogela ukunambitheka. Ngosizo lwabo, bayakwazi eyolanda ngisho izinguquko ezincane imvelo. Fish Pike, isibonelo, ngomlomo nje kuphela sondleke, kodwa futhi uzizwa touch of umhlaba, iyaphendula kweso, ukushintsha isiqondiso. amaseli ezizwelayo emlonyeni, ukudlulisa ezinzwa amaza, okuphawula nesenzakalo ingozi izithiyo noma ukudla.

Le nhlanzi ngempela fake athuthukiswe umuzwa lokushisa. Lokhu ukuzwela okusezingeni eliphezulu ukuze ekushintshashintsheni lokushisa nokucindezelwa alien nezilwane zasezweni.

izitho olfactory zezinhlanzi zitholakala ezinhlangothini ikhanda bese eyama Izigaxa encane. Ngosizo lwabo, bakwazi ukubona ushintsho olwenzeka emanzini kwamakhemikhali. Ikakhulukazi ngokucijile athuthukiswe lokuhogela e izilwane ukuzingela ebusuku. Ngokwesibonelo, inhlanzi Pike ungakwazi ukunuka inyamazane ukuthi sintanta a amamitha ambalwa kude.

i-lateral line. indawo

Ososayensi abaningi bakholelwa ukuthi i-lateral line, neyezinhlanzi - ebaluleke kakhulu sense sitho, kusiza izilwane uphile kahle. i-lateral line - uhlobo isikhungo esisodwa, eletha ihlanganise wonke amaseli ebucayi emzimbeni, ise ikhanda noma umzimba.

Isigungu seziPhathimandla itholakala wonke umzimba, kusukela ngasekhanda ophela ngesikhathi umsila. Anatomy of inhlanzi, yohlobo lwazo futhi zenyathi ukucacisa indawo i-lateral line nombala walo. Kokunye zinhlobo, kungaba ibukeke umugqa abe mhlophe qwa, kuyilapho abanye - emnyama, cishe black umugqa.

Inani elikhulu izinhlanzi lateral line uvezwa ikhophi eyodwa. Kodwa kukhona ezinye izinhlobo zawo ezingaba ukuziqhayisa ezinhlanu noma ngaphezulu. I-lateral line, neyezinhlanzi kungaba obonakala khulu zibukeke, futhi kungenziwa kufihlwe izikali ngokushesha lubonakale kuze ehlweni lomuntu. Kwezinye izinhlanzi yena arc emise, abanye - ngesimo amancane imivimbo nomqwayiba ekhanda.

Kukhona inhlanzi, okuyizinto elingenalo umqondo lesithupha. Lezi zihlanganisa mullet, Dallam, abanye cyprinodontiformes izinhlanzi umndeni.

I-lateral line siqukethe ...

Njengoba sishilo, i-lateral line, neyezinhlanzi uhlobo zobuchopho futhi izinzwa isikhungo ukuthi uqaphe ukuthi kwenzekani eceleni. Kuyini lokhu isikhungo?

i-lateral line imelela ekuqongeleleni eziningi zemizwa okuyinto zitholakala phakathi kwabo ngesikhathi isikhawu ezithile. I-receptor ingahle iziteshi umbala noma ayimigodi lapho okungadingeki ezinhlangothini emzimbeni. receptor Iningi kufihlwe ngaphansi kwesikhumba izinhlanzi. Bayingcosana ukuza kwamanzi futhi kufihlwe esikalini. Zifane ikhule ezimbotsheni evulekile esikhumbeni.

Ngaphakathi isiteshi i-lateral line ligcwele ketshezi. Nerve receptor (izinwele zabo sezinzwa) akhombise eshintsha isiginali ukuba lolu ketshezi uqobo. Noma yimuphi perturbation, izinguquko ingcindezi noma lokushisa kwamanzi kungabangela receptor futhi ngenxa yalokho, amanzi esiteshini kunyakaza. Izinguquko namandla kule ndawo zezinhlanzi, aba maningi kuzonqatshelwa izinwele yokwamukela, ulwazi ngokushesha ingena isimiso sezinzwa esiyinhloko.

Inani i-lateral line e inhlanzi

sixth sense, noma i-lateral line ivumela izinhlanzi ukuzizwa kusondela nezinye izilwane ezihlala emanzini, ngokushesha kakhulu kunalokhu eziyikho uzokwaziswa mayelana nezinhlaka emehlweni noma ukuhogela. I-lateral line uyakwazi wasithatha ushintsho encane kunazo zonke ingcindezi amanzi. Ososayensi bathi ibanga lapho ke uyakwazi ukunquma ingozi eyayisondela kasithupha usayizi (ubude), neyezinhlanzi.

Inani i-lateral line e izinhlanzi ongaboni kahle ezinkulu ikakhulukazi. Kunezilwane ukuthi bayakwazi ukuba baphendule kuphela ukuba isithunzi noma ukukhanya, kuba ngokuphelele ubengawazi ukunyakaza emanzini. i-lateral line kuleli cala, ukuze uvale isikhala nokungathuthuki noma ukungabi khona amakhono ezibukwayo noma olfactory.

Kusukela sideline ngokuvamile kuxhomeke ukuphila izinhlanzi. Uma lilimele, le ezenzeka ngaphandle ziqondakala izilwane kodwa ayikhanyi kakhulu ngakho. It uzoma zisuse nasezingozini ngaphandle, ngeke ukwazi ngokugcwele yokuzingela ukunikeza ukudla, ukucashela izitha. Futhi ngokushesha ayaphela.

i-lateral line futhi zidla

Mhlawumbe bonke abadobi abanolwazi bayazi ukubaluleka lateral line, neyezinhlanzi. Ngalo, izinhlanzi uyakwazi isicupho umsindo kulencane nokudludliza yamanzi. Njengoba izazi zithi, shot, ukuqhuma, ingxoxo evamile endaweni ngezwi eliphakeme, umthelela emgqeni amanzi ohlangothini ngokushesha "ngeke ngiwahogele." Ngakho-ke, izinhlanzi basabela, ethukile futhi abalekele. Kungenxa yalesi sizathu ukuthi abadobi zama ungalokothi wenze umsindo ku ichibi, hhayi ukhulumela phezulu kakhulu, akufanele ulahle into emanzini.

Movement, umsindo kancane nokudludliza akufanele ukudala umdobi futhi lolo emanzini. Anglers abanokuhlangenwe nakho bathi lolo akufanele ame emanzini, kufanele ngempela ukuhambisa, oscillating ketshezi. Kuphela kulesi simo izinhlanzi line yayo lateral ngeke ngiwahogele ukudla futhi izoya bebheke hook.
