Triangle Treefrog - Dendropsophus triangulum
This amazing frog with something like paws marks on its dorsum is scientifically named Dendropsophus triangulum (Hylidae), an uncommon species found in the Amazon Basin in Colombia, Ecuador, Peru, northwestern Bolivia, and Brazil.
It is small frog less than 40 mm with several color patterns or morphs, so many that It was described as a new species four times subsequent to its first description in 1869, because different colour morphs were thought to be new species.
In general, Dendropsophus triangulum bears two large pectoral patches that are in contact or nearly so (weak, distinctly apart), a light dorsum with or without a varying number of dark blotches or spots and red venter (lemon-yellow). However, this morph is quite different than the more standard form, more akin to the “giraffe phase” of the sister species Dendropsophus leucophyllatus.
