Nguva yetadpole nhanho inosiyana zvichienderana nemamiriro ekunze, asi inowanzogara kwemavhiki akati wandei kusvika kumwedzi mishoma.

Basa rekuchengeta kwevabereki muAmerican Toad egg hatching

American Toads haipe chero tarisiro yevabereki yakananga kune mazai avo kana macheche. Kana mazai akaiswa, vabereki vanovasiya kuti vakure vakazvimirira. Zvisinei, kusarudzwa kwenzvimbo yakakodzera yekukandira zai nehadzi kunogona kuita zvisina kunanga mukupona nekuchechenya kubudirira kwemazai.

Zvinogona kutyisidzira mazai eAmerican Toad uye hatchlings

Mazai eAmerican Toad uye hatchlings anotarisana nenjodzi dzakawanda dzinogona kuitika munzvimbo yavo. Hove dzinodya, zvipembenene, uye shiri zvinogona kutora mazai, zvichideredza mikana yekubudirira kubudirira. Pamusoro pezvo, kusvibiswa, kuparadzwa kwekugara, uye kushanduka kwemamiriro ekunze zvinogona kuisa njodzi dzakakura pakupona kweaya matanho asina njodzi eAmerican Toad life cycle.

Kuenzanisa American Toad yai kuchechenywa nemamwe marudzi

Kana tichienzanisa kuchechenywa kwezai reAmerican Toad nemamwe marudzi, misiyano inocherechedzwa uye kufanana kunobuda. Mamwe marudzi anogona kuva neakareba kana kuti pfupi incubation nguva, nepo mamwe anogona kuva akasiyana tembiricha zvinodiwa. Kunzwisisa kusiyana uku kunopa maonero akajeka pamusoro penzira dzakasiyana dzekuberekana dzinotorwa nemhando dzakasiyana dzeamphibian.

Mhedziso: The timeline yeAmerican Toad mazai ekuchechenya

Mukupedzisa, kuchechenywa kwemazai eAmerican Toad inzira inonakidza inokonzereswa nezvinhu zvakasiyana. Kubva pakukandira mazai ekutanga kusvika pakuchochonywa kwetadpoles, nhanho imwe neimwe inoda mamiriro ezvakatipoteredza kuti ibudirire. Nokudzidza nguva uye zvinhu zvinobatanidzwa muAmerican Toad kuchechenya mazai, masayendisiti anogona kuwana ruzivo rwakakosha mumatanho ekutanga ehupenyu hweamphibians anonakidza aya, zvichibatsira mukuchengetedza kwavo uye kunzwisisa kwehupenyu hwavo hwakasiyana.
