For the first time the information is presented on the linear dimensions of pre-larvae and larvae of the Talysh toad, Bufo eichwaldi from natural reservoirs in the southeast of Azerbaijan and bred in the laboratory from 17 to 46 stages of development.

The transition to exogenous feeding occurs starting from the stage 26 at the body length 4.69-5.73 and the tail 7.398.28 mm. Juveniles leave the water in the stage 44 at the body length 8,88-12,50 mm and the tail 0,1517,80 mm.
