Common water frog or green frog

The physical characteristics of the pond frog ideally lie intermediate between those of its parent species Pool Frog and marsh . Depending on the genetic disposition may resemble either more of one or the other kind of an individual as well . This concerns both the body size and the color and pattern of the top of the abdomen and limbs, or even , for example, the length of the lower leg in relation to the head-body length. Even for the hock on the rear inner toe applies to this intermediate position . When pond frog is the callus internus called hock and raised in relation to the toe length greater than in the marsh , but smaller and more asymmetric than the little water frog.

Specimens with genetic proximity to the marsh up to nine inches (male ) or eleven inches (females ) long. In the " normal case" , the top is colored green grass - but occasionally brown - and of a light green line along the center back (from the tip of the snout to vent ), and two clearly protruding back glands bars marked . Also, dark spots and stains can often be identified .
