EDGE Analysis

Thomasset's frog is the largest of the Seychelles’ native frogs, reaching a maximum length of 55 mm. Much information is lacking about this species, although it is known to be restricted to relatively undisturbed habitat in wet, rocky areas along streams, and has a preference for higher altitudes. This species is a rock climber, and is most often found at night sitting on rocks and large boulders. It is the rarest frog species in the Seychelles and is currently threatened by habitat degradation, mainly due to fire and invasive species. It might be at risk because of its small range, which makes it vulnerable to threats such as ecological disasters or climate change.
