Fig. 2. Male túngara and background spectral reflectance. (A) Average spectral reflectance of body regions from 15 male túngaras (solid lines) including head (+), dorsal ( ${blacktriangleup}$ ), ventral ( ${triangleup}$ ), non-inflated vocal sac (•) and inflated vocal sac ( ${circ}$ ). Average background material spectral reflectance is also shown (broken lines) including mud (•), stone ( ${blacksquare}$ ) and dead leaves ( ${diamondsuit}$ ). (B) Average spectral reflectance of the vocal sac of a representative male túngara frog in non-inflated (•) and inflated ( ${circ}$ ) states. Mean ± s.e.m. reflectance data include replicates made in left, middle and right areas of the vocal sac.
