Adult: Species description based on Ibanez et al (1999) and Savage (2002). A very large toad (males to 145 mm, females to 175 mm). Dorsal: Dorsal coloration varies from yellowish brown to dark brown. The dorsum is mottled in females and uniform in males. The paratoid glands are very large. Ventral: The ventral surface is cream-colored, with or without dark mottling. Eye: The iris is brown. Extremities: The hands and feet are mostly unwebbed.
Breeding season: Breeding occurs year-round (Ibanez et al 1999). Rhinella marina uses a wide variety of aquatic habitats for breeding, ranging from temporary pools to rivers and lakes (Ibanez et al 1999). Egg: Small, black eggs are laid in strings in shallow water (Ibanez et al 1999). Tadpole: The tadpoles are small and black (Ibanez et al 1999). The tadpoles often aggregate while feeding during the day (Hughey pers. obs.).
Habitat: Rhinella marina inhabits both humid and dry environments, as long as there is some vegetation available for cover (to 3000 m.). It is typically more abundant in disturbed habitats and rare in pristine forest (Ibanez et al 1999). Ecology: Rhinella marina nocturnal, and is commonly encountered on the ground in urban environments (Ibanez et al 1999). Call: A long, low trill (Ibanez et al 1999). The call can be heard from very far away (Ibanez et al 1999). Type locality: America
