Ollotis melanochlorus (Cope, 1877). Photographed at Monteverde, Costa Rica. Endemic to Costa Rica. This is a lowland moist and wet forest species usually seen during the wet season. Females reach 103 mm. Formerly placed in the genus Bufo.

Male Golden Toad, Ollotis periglenes (Savage, 1967). Near Monteverde, Costa Rica. While this species is called the "golden toad" it is clearly not golden in color. Males are bright orange, females are mostly black and red. Described by science in 1967 it is likely now extinct. This lower montane rainforest frog may have been wiped out by the infectious fungus that is decimating many amphibian populations. These photos were taken in 1986, only one male was observed in 1989 by researchers monitoring the population. The sexual dimorphism in this species is apparent from the lower photo. Formerly placed in the genus Bufo.

Marine Toad, Rhinella marinus (Linnaeus, 1758). Upper photo: a juvenile from Charlottesville, Tobago; lower photo, an adult from the Arima Valley, Trinidad. One of the largest toads, possibly the largest. Females may exceed 240 mm in length and females may weight up to 1.5 kg. They will eat almost anything, including manufactured pet foods. Females may lay more than 12,000 eggs at a time, the eggs hatch in 3-4 days, the larva metamorphose in 60-75 days, and captive specimens are known to live 16 years. The Marine Toad is native to the Western Hemisphere, and ranges from southern Texas throughout Central America, and into South America. It also occurs in natural populations on Trinidad and Tobago. However, it has introduced into Florida, the Caribbean, Australia, and other areas in the Eastern Hemisphere and has become an invasive species. In Australia and other parts of the Eastern Hemisphere it is known as the cane toad. [Formerly placed in the genera Bufo and Chaunus. Humans and dogs have died from ingesting the skin secretions and eggs of this toad.
