Brockets or brocket deer are the species of deer in the genus Mazama. They are medium to small in size, and are found in the Yucatán Peninsula, Central and South America, and the island of Trinidad. Most species are primarily found in forests. They are superficially similar to the African duikers and the Asian muntjacs, but unrelated. About 10 species of brocket deer are described.

The dwarf brocket, or chunyi, is a small species of deer native to the Andean highlands in western Bolivia and southeastern Peru, where it is found in forest and páramo. Its pelage is reddish-brown with dark grey foreparts and neck. The underparts are lighter brown, and the muzzle short and thick. It weighs around 11 kg.

The Mérida brocket, also known as the Meroia brocket or rufous brocket, is a small species of deer. It is found in forest and páramo at altitudes of 1,000–3,500 metres (3,300–11,500 ft) in the Andes of northern Colombia and western Venezuela.

This bird is commonly found from 1500–2400 meters above sea level.

The cream-backed poison frog is a species of frog in the family Dendrobatidae endemic to Colombia. Its natural habitats are subtropical or tropical, high-altitude grassland, shrub-dominated wetlands, swamps, intermittent freshwater marshes, rural gardens, urban areas, and heavily degraded former forests. The cream-backed poison frog is one of the less-toxic of the family. It has undergone several name changes since its discovery. Originally called Dendrobates subpunctatus, its name was changed to Colostethus subpuctatus once the family Dendrobatidae underwent a division of species and genera other than Dendrobates were coined. Recently, minor skeletal differences have separated the cream-backed poison frog from the rocket frogs, and placed it in another genus entirely, Hyloxalus.
