Description
These smooth-skinned frogs can grow to an average weight of 22.7 grams and length of seven to ten centimeters (2.8-3.9 in) with colors varying from gray to green, brown, yellow, or red and may be covered in blotches.[2] Males are usually smaller and darker than females and have nuptial pads on their first fingers to help hold on to the female during mating. The underbelly is white or yellow often with speckles.[3]
Breeding
Around three years of age, Rana temporaria temporaria return to the site where they first developed. Males return first and produce a low pitch growling croak to attract mates. A successful mate will wrap his forelimbs around the female in amplexus.
