Common Name: Rusty Robber Frog
Scientific Name: Strabomantis bufoniformis
Family: Strabomantidae
Locations: Colombia, Costa Rica, and Panama
Size: 2 – 3.7 inches (50 – 94 mm)

The Rusty Robber Frog lives along the streams in lowland and moist forests. They are primarily nocturnal, spending its nights catching insects near the stream. While the frog may live near the stream, they don’t reproduce in them. The female frog lays her eggs in the sand. The frogs are a direct developing species, skipping a free living larval phase (aka no tadpoles).

The International Union for the Conservation of Nature (IUCN) Red List assesses the Rusty Robber Frog as Endangered. The two main problems for the frog are Chytrid Fungus and habitat destruction. The frog is probably extinct in Costa Rica now since it hasn’t been seen there since 1978.
