Dzinozivikanwa nemitsetse yadzo mitema neyeyero, inofanana nepeteni yengwe, nekudaro zita radzo. salamanders idzi dzinobva kuNorth America uye dzinowanikwa munzvimbo dzakasiyana-siyana, kusanganisira masango, masango, uye kunyange pedyo nemisha yevanhu. Zvisikwa zvehusiku, zvinonyanya kushanda panguva yehusiku, uye zvibori zvakanakisa. Tiger salamanders anochinjika zvakanyanya uye anogona kugara munzvimbo dzese dzepasi uye dzemumvura.

Anatomy yeTiger Salamanders

Tiger salamanders ane yakasarudzika anatomy inovagonesa kurarama munzvimbo dzakasiyana dzekugara. Vane muviri wecylindrical une muswe wakareba, unoyera kutenderera masendimita matanhatu kusvika masere pakureba. Ganda ravo rakatsetseka uye rakanyorova, zvichiita kuti vafeme nepaganda ravo. Vane makumbo mana ane nzara dzakakura zvakanaka, dzinobatsira mukuchera nekubata mhuka. Meso adzo madiki uye akaurungana, uye ane muromo wakapamhama une mazino akapinza. Aya salamanders anewo matinji akasarudzika kumusana anonzi parotoid glands, ayo anoburitsa zvinhu zvine muchetura senzira yekudzivirira kubva kune zvikara.

Hupenyu Kutenderera kweTiger Salamanders

Hupenyu hwekutenderera kwetiger salamanders hunokatyamadza. Zvinotanga nehadzi inokandira mazai mumiviri yemvura yakaita semadziva kana madziva. Mazai aya anochochonya kuva mhungu, inozivikanwa se "salamander tadpoles." Tadpoles ane gill uye anogara mumvura, achidya tupukanana tudiki. Sezvavanokura, vanoita metamorphosis, panguva iyo vanokura mapapu nemakumbo. Shanduko iyi inovabvumira kusiya mvura vogara panyika. Kana vanyatsokura, vanova vakura tiger salamanders uye vakagadzirira kuroorana uye kubereka.

Habitat uye Kugoverwa kweTiger Salamanders

Tiger salamanders inogona kuwanikwa munzvimbo dzakasiyana siyana dzekugara muNorth America. Iwo akanyanya kuwanda muUnited States, Mexico, uye Canada. Aya salamanders anochinjika uye anogona kurarama munzvimbo dzakasiyana siyana, kusanganisira masango, masango, uye kunyange magwenga. Kazhinji dzinowanikwa pedyo nemvura, semadziva, madziva, kana machakwi, kwadzinoberekera nekukandira mazai. Tiger salamanders anozivikanwawo kuchera pasi pevhu, achitsvaga pekugara panguva yekunyanya mamiriro ekunze kana kudzivirira zvikara.

Kudya uye Kudyisa Tsika dzeTiger Salamanders

Tiger salamanders anodya uye ane chikafu chakasiyana. Semakonye, ​​anonyanya kudya zvipenyu zviduku zvemvura zvakadai sezvipembenene, crustaceans, nehove duku. Kana vachinge vaita metamorphosis uye vova vanhu vakuru, kudya kwavo kunowedzera kusanganisira huwandu hwakawanda hwemhuka. Vakura tiger salamanders vanodya zvipembenene, dandemutande, makonye, ​​zvipuka zviduku, uye kunyange dzimwe amphibians. Vavhimi vane hunyanzvi, vachishandisa pfungwa yavo yekunhuwidza uye kuona kwakanaka kwazvo kutsvaga nekubata mhuka yavo. Mazino avo akapinza uye shaya dzine simba zvinovabvumira kudya mhuka yakakura kudarika saizi yavo.

Kubereka uye Kusangana maitiro eTiger Salamanders

Tiger salamanders anoratidza mafambiro anonakidza ekubereka. Munguva yekuberekesa, iyo inowanzoitika munguva yechirimo kana kutanga kwezhizha, varume vanoenda kumadziva ekuberekesa uye vanobudisa nhare dzakasiyana kuti vakwezve vakadzi. Kana mukadzi angosarudza wokuroorana naye, vanoita kutamba kwokupfimbana, kunosanganisira kutenderera uye kubata-bata. Mukono unozoisa spermatophore, pakiti yembeu, pauriri hwedhamu, iyo hadzi inounganidza ichishandisa cloaca yayo. Fertilization inoitika mukati, uye mukadzi anozokandira mazai ayo mumvura, umo anokura kuita mhungu.

Kukura uye Kuvandudza Matanho eTiger Salamanders

Mushure mekuchechenya kubva mazai avo, tiger salamanders vanotanga rwendo rwavo semakonye. Sezvavanokura, vanokura zvishoma nezvishoma mitezo uye vanorasikirwa nemakumbo avo, vachichinja kuva vechidiki vepanyika. Panguva iyi, vanoramba vachikura uye vachikura kusvika vakura. Mwero wekukura kwetiger salamanders unogona kusiyana zvichienderana nezvinhu zvakaita sekuwanikwa kwechikafu, tembiricha, uye mamiriro ekugara. Zvinotora makore akati kuti kuti vasvike pakukura pabonde, vamwe vanhu vachitora makore anosvika matatu kana mana kuti vakure zvizere.

Zvinhu Zvinokanganisa Kukura kweTiger Salamanders

Zvinhu zvinoverengeka zvinokonzera kukura kwetiger salamanders. Kuvepo kwechikafu chakakwana kwakakosha pakukura nekukura kwavo. Kuwana kudya kwakasiyana-siyana, kusanganisira mapuroteni-akapfuma nyama, kunokurudzira kukura nekukurumidza. Zvinhu zvakatipoteredza zvakadai setembiricha nehunyoro zvinoitawo basa rakakosha. Salamanders munzvimbo dzinodziya dzinowanzokura nekukurumidza kupfuura idzo dziri munzvimbo dzinotonhora. Hunhu hwekugara uye kuwanikwa kwepokugara kwakakodzera kunogona kukanganisa kukura kwekukura. Pamusoro pezvo, makwikwi ezviwanikwa uye predation pressure inogona kukanganisa kukura, sevanhu vakatarisana nemakwikwi epamusoro kana kudzvanyirira vanogona kugovera simba rakawanda mukupona pane kukura.

Avhareji Saizi yevakuru Tiger Salamanders

Adult tiger salamanders vanozivikanwa nehukuru hwavo hunoshamisa. Paavhareji, vanoyera pakati pe6 kusvika ku8 inches pakureba, nevamwe vanhu vanosvika 14 inches. Chimiro chavo chemuviri chakasimba chinobatsira pakukura kwavo kwakakura. Nekudaro, zvakakosha kuti ticherechedze kuti panogona kuve nekusiyana kwakakura kwehukuru pakati pevanhu, vamwe vari diki kana hukuru pane avhareji saizi.

Kusiyana kwehukuru pakati peTiger Salamanders

Tiger salamanders anoratidza hukuru hwakasiyana, mukati uye pakati pehuwandu. Zvinhu zvakawanda zvinoparira kusiyana uku. Genetic factors dzinoita basa, sezvo vamwe vanhu vangagara nhaka majini anovafungidzirisa kukura kana kuita madiki. Zvinhu zvezvakatipoteredza zvinewo kukanganisa, sezvo salamanders munzvimbo dzakapfuma-zviwanikwa dzinogona kuwana chikafu chakawanda, zvichikonzera hukuru hukuru. Pamusoro pezvo, kukwikwidza uye kudzvinyirirwa kunogona kukanganisa saizi, sevanhu vakatarisana nemakwikwi makuru kana predation kudzvanywa vanogona kugovera simba rakawanda mukukura kana kupona, zvichiteerana.

Rekodha-Kuputsa Tiger Salamanders: Yakakura Yati Yambowanikwa

Munhau yose, kwave kune mishumo yezvikuru zvikuru zvetiger salamanders. Iyo yakakura kupfuura yese yakamborekodhwa yakawanikwa muKansas, inoyera 16 inches pakureba. Ichi chienzaniso chinoshamisa chakaratidza hukuru hwechokwadi hunogona kuitika hweamphibians aya. Nekudaro, vanhu vakadai vanotyora rekodhi havawanzo, uye mazhinji etiger salamander anowira mukati meavhareji saizi renji. Kuwanikwa kwezvienzaniso izvi zvakasarudzika kunoshanda sechiratidzo chekusiyana kunoshamisa uye kuchinjika kwezvisikwa izvi zvinonakidza.

Mhedziso: Kunzwisisa Kukura kweTiger Salamanders

Kukura kwetiger salamanders inzira yakaoma inopesvedzerwa nezvinhu zvakasiyana, kusanganisira genetics, nharaunda, uye kuwanikwa kwezviwanikwa. Aya maamphibians anotarisana nehupenyu hunonakidza, kuchinja kubva kumvura yemvura kuenda kune vanhu vakuru vepanyika. Kunzwisisa zvinhu zvinokanganisa kukura kwavo nekusimudzira kunopa ruzivo rwakakosha mune yavo ecology uye biology. Nepo tiger salamanders vachizivikanwa nekukura kwavo kunoshamisa, vanoratidza mutsauko wakakura muhukuru pakati pevanhu uye huwandu hwevanhu. Zvingave zvihombe kana zvidiki, zvisikwa izvi zvinoramba zvichitikwezva nekugona kwavo kunoshamisa kuchinjika uye kubudirira munzvimbo dzakasiyana dzeNorth America.
