... WGS84; 784 m a.s.l.), we observed a male individual of Macrobrachium potiuna Müller 1880 (carapace length of 45 mm) feeding on a small-sized juvenile treefrog (snout-vent length ca. 25 mm, ~ 55% of the shrimp size) (Figure 1). These anurans are primarily arboreal and usually inhabit stream beds, bromeliads, or rocky cavities in the Atlantic Forest (Frost 2011). ...
