Life History, Abundance, Activity, and Special Behaviors
Reproduction occurs in lakes, ponds, swamps, puddles, old riverbeds, ditches and rivulets with stagnant or semi-flowing water. Males enter breeding areas before females. Amplexus is pectoral. The clutch in the form of two strings of eggs, 1.5-2.3 m in length, containing 1200-7400 eggs. Metamorphosis occurs in summer. Mass mortality of B. gargarizans larvae occurs in pools with high tadpole density of the brown frog Rana dybowskii.
Sexual maturity of this toad is probably attained during the 3rd-4th year of life; the majority of adults are 5-6 years old.
Adult B. gargarizans consume insects, especially Coleoptera and Hymenoptera. Other invertebrates such as Mollusca, Myriapoda and Arachnoidea are eaten in smaller quantities.
