Stephen's rocket frog (Anomaloglossus stepheni) is a frog. It lives in Pará and Amazonas in Brazil and in Suriname.[2][3][1]

Body

The adult male frog is 14-17 mm long from nose to rear end and the adult female frog was 16-18 mm long. The skin of the frog's back is more than one brown. There is a darn brown stripe from the nose to the middle of the body. There are blue-white dots under it and on the toes. The male frog's voice sac is white or gray in color. Young frogs have dark heads and light brown backs.[3]

Home

These frogs are awake during the day.[3] These frogs live on the dead leaves on the ground in forests that have never been cut down and forests that are growing back.[1]

This species lives in the leaf-litter of old growth and secondary tropical rainforest. It lays its eggs on land, and tadpoles are nidicolous[1]

Scientists have seen this frog inside protected places: Área de Proteção Ambiental de Presidente Figueiredo - Caverna do Moroaga, Floresta Nacional de Saraca-Taquera, Floresta de Faro, Reserva Biológica de Uatuma, Reserva Biológica do Rio Trombetas, Reserva Florestal Adolpho Ducke, and Reserva Extrativitsa Riozinho do Anfrisio.[1]

Food

Adult frogs eat termites, flies, and beetles. Young frogs eat collembolans and mites.[3]

Young

The frogs have young between November and March. The female frog lays eggs on the sides of rolled leaves. She lays 3-6 eggs at a time. The tadpoles grow in nests on land. The male frog watches the eggs and tadpoles.[3][1]

Danger

Scientists say this frog is not in danger of dying out. The forests are large.[1]
