Its two recognized subspecies include the Bronze Frog and Northern Green Frog.

One will also notice prominent seam-like skin folds running down the sides of its back. This is one feature that distinctly distinguishes the green frog from its look-alike bull frog.

Call

The loud and distinct call of the male green frog sounds exactly like a plucked banjo string. It is usually produced as a single note. The male frogs call from their territory and their call is a way of defending their territory.

Habitat and Distribution

The Green frog breeds in the eastern half of the United States and Canada. Its populations are especially concentrated in the southeast corner of Manitoba.

Green frogs can be found in a variety of shallow fresh water habitats including ponds, lakes, road side ditches, streams, swamps and brooks. These frogs instantaneously leap into the water on sensing danger.

Diet

These frogs feed on almost any prey that it can capture and fits its mouth. Their diet includes invertebrates, spiders, shrimp, fish, smaller frogs, snails, smaller snakes and tadpoles.

Green frog tadpoles are known to feed on algae and water plants.

Reproduction

The peak breeding season begins from April and continues till mid August. These frogs usually prefer semi-permanent or permanent freshwater as breeding grounds.

It is interesting to note that the male green frogs call for their mates from their own respective territories; they do not bunch up while calling for their mates as in the case of most frogs.

The actual act of mating occurs in a position where in the male grasps the female using his forelimbs, from her hind end or behind. During the act, the female frog releases her eggs while the male releases his sperms that get to the eggs for the process of fertilization to occur.

Females can lay up to 4000 eggs; the eggs are deposited in water and are usually attached to submerged vegetation.

The green frog tadpoles are identified to be olive green in color; however they may appear iridescent creamy white from below. The tadpoles metamorphose and turn into froglets in period involving more than a year (approximately 400 days).

Male frogs reach their sexual maturity by the time they are 1 year old; females take slightly longer and become sexually mature in around 2 – 3 years.

Behavior

The adult green frogs mostly prefer to stay in water. However, the juveniles can be spotted over land especially when there is wet grass and soil.

Habitat: If you intend to keep one or two frogs, a 10 gallon aquarium is what you will require. It is important to remember that you need to increase the aquarium size if there are many frogs.

The aquarium should comprise of half land/ half water kind of a set up; similar like the natural habitat that these frogs are generally accustomed to.

There are few things that you cannot afford to miss when you set up the habitat for the green frog. Make sure to choose a soil or sphagnum moss and keep it damp. However, first things first so an aquarium without a top or cover can be fatal; the aquarium has to have a top so that the frog cannot escape.

A water dish (preferably 3 to 4 inches deep) will be excellent for your pet frog to go in; the water has to be changed regularly on a daily basis.

You are recommended to use logs or bark pieces that are large enough to be serve as hiding places for your frog.

A UV fluorescent lamp can be used so that the frog can bask and derive its nutrients.

Tadpoles can be kept in water filled aquariums.

Feeding: Your new pet friend will love to eat live crickets, earthworms, slugs and crayfish. Tadpoles should be fed fish flakes, steamed vegetables and zooplankton. Please note that it is not recommended to feed celery or salad to the tadpoles.

Hygiene: It is important to clean the tank atleast once in a week. It is recommended to use 1% of bleach solution in order to clean the tank; but make sure to clean the tank thoroughly again to erase the foul smell of the bleach. Using a tank vacuum cleaner or turkey baster will make it convenient for you to pour the used and dirty water out of the tank.

It is also important to wash the rocks and furniture with hot water on a regular basis to destroy the germs.
