Spring Peeper

Description:

Spring peepers are tan or brown in color with a dark cross that roughly forms an X on their dorsa (thus the Latin name crucifer, meaning cross-bearer[2]), though sometimes the marking may be indistinct.[3][4] They have a body length between less than 1 in (25 mm) to 1.5 in (38 mm)[4] and a weight between 0.11 and 0.18 oz (3.1 and 5.1 g).[3] The species has large toe pads for climbing, although it is more at home amid the loose debris of the forest floor.[3] The color variations of the P. crucifer are mostly tan, brown, olive green, and gray. Females are lighter-colored, while males are slightly smaller and usually have dark throats. This frog has a vocal sac located by its throat, which expands and deflates like a balloon to create a short and distinct peeping sound. Only males have the ability to make this loud high-pitched noise, and they use it to attract mates. [wikipedia]
