Sphaenorhynchus caramaschii is known to occur in the highlands (the type locality is at 910 masl) of the states of São Paulo, Paraná, and Santa Catarina; in Santa Catarina it also occurs in a lowland locality (about 150 masl)(Toledo et al., 2007).
Habitat and Ecology
The species can often be found in open and flooded areas, and permanent swamps, generally with deep waters (i.e. over 1m deep). Water bodies with floating vegetation are also favoured (L.F. Toledo, pers. comm. 2008). Sphaenorhynchus caramaschii can also be found in permanent and temporary ponds in open areas. Reproduction occurs in the rainy season (September-March), where males call from floating vegetation in ponds. Eggs are laid in lentic water, from which exotrophic tadpoles emerge. The eggs are attached individually to submerged vegetation (Toledo et al., 2007).
It seems to be an abundant species (Toledo et al., 2007).
No threats are currently known for this species.
No conservation measures are currently known for this species.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its likely wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
Sphaenorhynchus caramaschii can be distinguished from other similar species by a combination of morphological characters and advertisement call features (Toledo et al., 2007).
