Distribution and Habitat
Country distribution from AmphibiaWeb's database: Brazil
The species is most often found on the edges of the Reserva Florestal Adolpho Ducke in Brazil and in large open areas.
Life History, Abundance, Activity, and Special Behaviors
The species is terrestrial and nocturnal. In the Reserva Florestal Adolpho Ducke in Brazil, it reproduces in small and large ponds throughout the year, but with a peak in the wet season. Clutches contain around 900 eggs that are deposited on the surface of the water in gelatinous strings. The tadpoles are light gray and live on the bottom of ponds.
Juveniles of Bufo marinus are similar in general form and color to B. granulosus, but B. marinus has distinct parotoid glands behind the eyes, whereas the parotoid glands of B. granulosus are smaller and difficult to see in juveniles.
