Green Frog Anatomy

Green frogs are  easy to find nestled stoically among weeds and high grasses within, and adjacent, to ponds.  These frogs are variably colored, but typically have tan legs with black stripes.  Often mistaken for bull frogs (another common aquatic species) during all stages of life.  Newly hatched tadpoles cannot be visually distinguished from bull frogs, but adult species can be differentiated by inspection of dorsal lateral-ridges (DLR):  green frogs have DLR; bull frogs do not have DLR.   See above photo showing dorsal-lateral ridges of green frog.

Green Frog in water

Green frogs are an extemely common type of anuran that is native to United States and Canada.  An anuran is  an order of  amphibian comprising  frogs, toads, and tree frogs that lack a tail in  adult stage and have long hind limbs for leaping and swimming.

They will instinctively remain still and rely on camouflage to avoid any perceived threat.  Venture closer to a pond and these smaller frogs (approx. 3″) will spring into the pond (if on land), or dart underwater.  Wait 10 seconds and they will typically resurface within the same square meter of the pond.  A quick hand can catch this Green Frog Top Viewspecies of frog fairly easy; a net is a guaranteed catch.  These frogs will not venture far from water, which is useful to evade predation and essential to avoid dessication.  These frogs also rely on their freshwater habitat for mating, laying eggs, and hunting prey.   Freshwater habitats with duckweed provide
