A large toad measuring up to 100 mm in length. Like all true toads they have glandular skin, no teeth and parotid glands. They are found in the African savanna where they prefer wooded areas with high day time temperatures. They are cryptically coloured to help them blend into their terrestrial habitat where they spend the majority of time. Each year they make long journeys overland to breed in temporary water bodies such as vleis, dams and pans.
To avoid detection the tadpoles of the eastern olive toad will match the substrate of the pool by assuming either a darker or lighter shade.
Male eastern olive toads appear to be faithful to their call site. Each breeding season they will return to the same position.
Eggs of the eastern olive toad hatch in just 24 hours. It then takes 64 to 90 days for them to change into their adult toad form.
The inside of the eastern olive toad’s legs are red. This is called flash colouration which is designed to confuse predators.
