Yiyiphi eklasini iintlanzi? Ezona mpawu, izakhiwo, zikhwelwe fish

Sturgeon, zeCARP, herring, trout, zeCARP, zeCARP zesilivere, zeCARP - intlanzi odumileyo. Olu luhlu alupheli. ixabiso labo lorhwebo kunzima ukuba zazi. Enyanisweni, iklasi ka intlanzi zahlukahlukene kakhulu. KABLOOM Modern ezingaphezulu kwama-20 amawaka iintlobo zezi izilwanyana zasemanzini. Ngenxa indlela afakiwe izakhiwo bakwazi kakuhle le meko kwaye uthabathe ngendlela ekwindawo lubalaseleyo. Ukuze Iklasi kuquka intlanzi, ngaphandle isakhiwo sayo? Ezi kunye nezinye mibuzo aza kuphendulwa kweli nqaku.

zimpawu fish

Akumangalisi malunga sizithembile abantu bathi: "Ndiziva Ndingathanda intlanzi emanzini." Izazinzulu bazi ukuba intlanzi yokuqala kuhlala kude emva nexesha Silurian. Ngaphandle kokuba kunxibelelana ookrebe zale mihla kunye nemihlathi ezinokususwa, apho amazinyo abukhali. Izigidi iminyaka, iguqulwe kwaye wafumana inani yemisebenzi emitsha kwinkqubo nolwamkelo nasekusungulweni yeentlanzi.

Njengokuba izilwanyana zasemanzini, bonke baya kuba ukumila iimeko iqala ngokupheleleyo okanye ngokungaphelelanga esikhatshwa emzimbeni iintlobo ezahlukeneyo amaphiko, kwaye amalungu zokuphefumla zizinto iigilizi. Ezi mpawu eqhelekileyo onke amalungu ale umanyano indlela. Kodwa yintoni eklasini iintlanzi, unokuphendulwa ngokuqwalasela iiyantlukwano zabo ebalulekileyo. Okwangoku, apho kukho ezimbini: amathambo kunye intlala.

Iimpawu ze isakhiwo sangaphandle

Umzimba ngokupheleleyo yonke intlanzi ligutyungelwe esikalini. Ikhusela ulusu yokozela zasemanzini zochuku amanzi obomi. Ngapha koko, abaninzi kubo ukuchitha ingxenye enkulu ebomini babo motion. ukhuselo eyongezelelweyo esuka zochuku yaye isixa esikhulu yencindi, leyo esisityebi esikhumbeni. Oku kunceda ukuba asinde iintlobo ezininzi kwezimo ngexesha lembalela. Ayizizo zonke iintlobo omzimba intlanzi sigqunywa ngokupheleleyo esikhatshwa. Umzekelo, ukrebe ibekwe inani elinye phezu komzimba, ngembonakalo efana amazinyo abo. Kunjalo wathi amalungu amaninzi umyalelo Sturgeon. Uninzi isikali fish ingamathambo akhuselwe, ngathi isikrweqe olomeleleyo. Iqhuba imisebenzi eyongezelelweyo: ukuzifihla kumarhamncwa, siluleka imibala iintlobo ezidla kwaye enobuhlungu, ukwalathelwa isini, ku vangama ka ukukhanya emanzini.

Ubume bale amaphiko

Enye into uphawu kuba phambi amaphiko yeentlanzi. Ngokuseka bangamalungu ukuhamba emanzini, yaye ezinye iintlobo yamandulo Unga igaqele ngabo. Amaphiko kuhlanganiswa bangamaqela amabini. Le kwisibini sokuqala: esiswini kunye nesifuba. Baya kuba negalelo nokugcinwa iintlanzi esikalini emanzini. Umsila zibe unpaired, ezimpundu kanye amaphiko. Zisebenza efana ivili lokuqhuba kunye engalawulekiyo umzimba yezilwanyana zasemanzini kwelo cala. Ngenxa nasekusungulweni amaphiko zeentlanzi wambumba bangamalungu ezirhubuluzayo izilwanyana.

Kwi umzimba wentlanzi uza ungabona ngokulula i sideline. Eli lungu ezohlukileyo eseleyo kunye kwebala, uphawu kuphela iintlanzi.

Isakhiwo sangaphakathi iintlanzi

iimpawu zayo ezinxulumene yokuhlala zolwelo izikhungo kunye neenkqubo ezi zilwanyana. Musculoskeletal imelwe elimele. Kuxhomekeka iklasi ezikhandelwa intlala okanye inyama ithambo. Onke amathambo amathambo iintloko fixedly idityaniswe, ukongeza emhlathini asezantsi. Oku kukuvumela ukuba thatha ngokulula imveliso yeentlanzi. Isakhiwo eli candelo asemzimbeni ikwaquka isiciko kumculo kunye arc ngasekho yayo iqhotyoshelwe kunye nemibutho neentlanzi nokuphefumla - iigilizi. skeleton yezihlunu ibandakanya omqolo ngamnye oqhagamshelwano phakathi kwaye zigxunyekwe, yaba lukakayi. Yi kummandla buti yomqolo eqhotyoshelweyo ezimbanjeni. reyi Amathambo fin ufundwa. bakha ijwabu ithambo. Kodwa amaphiko nesithandwa nawo nebhanti. Ezi izihlunu zincamathele, ebakhokela motion.

Inkqubo kokudla ngokusebenzisa ngohlobo yeentlanzi. Iqala komgodi oropharyngeal. Uninzi iintlanzi eziphezu emihlathini, amazinyo abukhali, ezisetyenziswa ukufaka eqwengayo ukutya. Kwinkqubo ukwetyisa inxaxheba amadlala enzyme - isibindi nepancreas. Kwinkqubo kusahlulwa netyuwa yokucolwa indima enkulu intlanzi ukudlala iperi kwizintso. Ngaphandle, zivulwe kunye ureters.

Zeentlanzi izilwanyana zinegazi elibandayo. Oku kuthetha ukuba ubushushu bomzimba wabo luxhomekeke ezenzeka kokusingqongileyo. Olu phawu buchazwa yinkqubo kwegazi. Oku imelwe intliziyo egumbini-amabini kunye nesakhiwo nemithambo ezivaliweyo. Ngexesha igazi lakhe intshukumo lwemithambo kunye umfutho oxutywe.

Le luvo iqulathe ingqondo kunye umnqonqo kunye luvo. Yaye inxalenye yayo peripheral - luvo. Xa ingqondo, uphuhliso ethile lifika kwiCerebellum. Le ndima yenza iintshukumo ngokukhawuleza kwaye siququzelelwa iintlanzi. Iimvakalelo bayakwazi ukuqonda nasiphi eku-, kunokwenzeka kwi-bume emanzini. Ukususela lens iliso kweentlanzi ayitshintshi imilo layo kunye nendawo izilwanyana ungabona umgama omfutshane kakuhle kuphela. Kodwa uyakwazi ukwahlula imilo kunye nombala izinto ezahlukeneyo. sound ukuzala zomzimba kwaye iqulathe kwindlebe engaphakathi lu dityanisiwe isakhiwo onoxanduva eseleyo.

Veliswa iintlanzi nalo uneempawu zawo. Ezi izilwanyana dioecious, kunye uhlobo yezichumiso lwangaphandle.

Yintoni zidala

Inkqubo intlanzi lokuvelisa kwakhona ngokuba amaqanda. Senzeka emanzini. Imazi izala amaqanda, kwaye inkunzi uyitha kulwelo yakhe ZakwaLizwi Zehlabathi. Ngenxa yoko iqanda. Ngenxa iyantlukwano ngalinye mitotic kulowo iphuhlisa ngamnye omdala.

Ngamanye amaxesha lokwanda intlanzi unxulunyaniswa yokufuduka amaqanda kunye notshintsho okubonakalayo nokuziphatha kunye nolwakhiwo iintlanzi kweli xesha. Umzekelo, nesalmon zakha neenkomo ezinkulu, eziquka ezo izakususwa elwandle efikelela kuyo imilambo. Ngeli hambo kufuneka boyise imiqobo emininzi, ufuna ukunihlasela bakuthembe. Le ntlanzi zakha idolo ngasemva, imihlathi, wajika ngaphakathi ngaphandle izandla neenyawo. Baphulukene amandla amaninzi, emva kokuba inkqubo abadala neqanda kufa. Ngokumangalisayo, Qhotsa abaselula kubuyela phezu ngokwabo kwi yokuhlala enye.

iqela fish

A Iyantlukwano enkulu yimfuneko Ukuhlelwa eli qela kwezilwanyana. Ngoku izazinzulu baye bakhomba imiqondiso, leyo zihlelwe eklasini Pisces. ukubandakanya ngendlela uzimisele bubukho esinyini qubha, slits kumculo okanye iziciko kunye nohlobo esikalini. Ngoko ke akwenzeki ukwahlula phakathi ngethambo kunye nentlanzi cartilaginous. Kukho ezinye izinto ezibonisa apho ezi zilwanyana ezidityanisiweyo iqela. Umzekelo, iintlanzi ukuhamba ngenxa besasaza kwezinye iindawo zokuhlala, eyaziwa ngokuba sisaqhubeka. Kodwa, banikwa lo umda, umahluko phakathi kwamalungu yorhwebo bokuhombisa yezi izilwanyana zasemanzini.

neentlanzi cartilaginous

Yeyiphi eklasini intlanzi skeleton cartilaginous, kumculo slits ngumlomo oya ngaphandle? Easy ukuze bangazi. Le ntlanzi cartilaginous. Bona abanayo isinye qubha, ngoko nokuba bahlala phezu emazantsi, okanye sihlala motion. Sawfish, emhlophe, basking, ukrebe, stingray, stingray ... uyazi iintlanzi ezinjalo. Uluhlu ezidla eziyingozi ungaqhubeka uMtyholi elwandle, stingrays kunye fox ulwandle. Ezi zidalwa ulwandle ziyingozi kakhulu ngenxa yomphefumlo kwezilwanyana nabantu. Nangona bafumana neentlanzi cartilaginous kunye nezinto kakhulu msulwa. Ngoko ke, ukrebe nezihlahla dogfish utya intlanzi intlanzi. Ngaphandle awoyikekayo, akukho ingozi akukho ngabantu.

fish bony

Ngomhla umbuzo apho eklasini iintlanzi kakhulu luninzi, ukuphendula, mhlawumbi, yonke schoolchild. amathambo wabo ubunjwe ngokupheleleyo ithambo. Swimbladder ibekwe umngxuma emzimbeni, ivumela abanini wawo kumhlathi emanzini. Kwakukhuhlwa anxibé izingxobo kumculo hayi mingxuma ngamnye zivulwe ngaphandle. Ezi mpawu ziye iintlanzi esisodwa.

Ixabiso lentlanzi

Abameli lomqolo superclass ngokuyintloko babe ixabiso yorhwebo ebalulekileyo. Umntu othe wayidla inyama yabo amaqanda okunezondlo neprotini-rich. A Inani iresiphi kwiintlobo ezahlukeneyo akhawunti akazi. amafutha ane kudala lusetyenziswe njengendlela ukunyanga izifo zemiphunga yintsholongwane kunye wentsholongwane egazini. Abantu ngonyaka abambe inani elikhulu kweentlobo kunye eendidi zabo. Inyama kunye isidlo bone nako ifunyenwe. Isetyenziswa njengento isichumiso kunye ukudla izilwanyana ezininzi.

Kwiminyaka yakutshanje ukwandisa ukuthandwa lokuloba ezemidlalo, etsala nxaxheba abasuka kumazwe awahlukeneyo. Ndize ndikhwele izikhokeli, ezalisekisa yonke iminqweno, amaphupha kanye ngamnye wethu!

Ngenxa yoko, udidi apho lilungu iintlanzi kumiselwa liSebe awohluke yesakhiwo, umbutho kunye nendlela yokuphila.
