The Sphaenorhynchus surdus, also known as Cochran's lime treefrog, is a type of frog that belongs to the Hylidae family. This special frog is found only in southern Brazil. It lives in the eastern parts of the Paraná, Santa Catarina, and northeastern Rio Grande do Sul states.
For a long time, many frogs from the south of São Paulo state all the way to Rio Grande do Sul were thought to be S. surdus. But in 2007, scientists described a new species called Sphaenorhynchus caramaschii. This helped them understand the differences between these frogs.
About Cochran's Lime Treefrog
Adult male Cochran's lime treefrogs are quite small. They measure about 23 to 29 millimeters (less than 1.5 inches) from their snout to their rear end. They have a dark line that runs along their back and sides, from their nose almost to their legs.
These frogs do not have an ear drum (called a tympanum) that you can see from the outside.
When they are young, these frogs are tadpoles. A large tadpole can be about 53.5 millimeters long in total. Its body alone makes up about 18.5 millimeters of that length.
Male frogs make calls during the hot, rainy season. They often call from plants floating on the water. Their calls are short, usually lasting less than 2 seconds. The main sound of their call is around 2.2 to 2.4 kilohertz.
Where They Live and How They Are Protected
Cochran's lime treefrogs live in low bushes. These bushes are usually found around large, permanent lakes. They can live at different heights, from about 100 to 1200 meters (about 330 to 3,900 feet) above sea level.
Even though there are many of these frogs, they face a challenge. Water pollution is a threat to their homes and their survival. Protecting their watery habitats is important to keep them safe.
