Frog Types

American Bullfrog

• The American bullfrog is green and resides as far north as Canada, Nova Scotia and as far as Mexico. Normally, American frogs average 4 to 8 inches in length but some grow longer. This frog thrives in large pools of water, such as marshes, ponds and lakes. Bullfrogs have a wide-ranging diet and will eat just about anything that fits into their mouths including insects, fish, small snakes and even baby birds, according to the Fairfax County Public Schools website.

Tomato Frogs

• Found in the lush forests of Madagascar, the tomato frog has brilliant, fiery red skin. Its throat and yellowish belly also comes with light spots. During the first few months of birth, the skin of tomato frogs comes in a combination of red and yellow or orange spots. Their behavior is somehow similar to other frogs when they hunt and catch prey. While waiting for insects to pass by, they usually stay underneath the sand to keep their bright-colored skin out of sight. They strike potential prey animals as soon as they spot them. Whenever they feel threatened, they try to double their size by sucking air.

Monkey Frogs

• The monkey frog is a green species that thrives in the rain forests of Peru. Instead of spending most of their time on the ground, monkey frogs enjoy resting on high branches of trees. These rainforest frogs also have long limbs, which gives them tremendous flexibility. They can easily wrap their body and legs around sturdy leaves as they wait for insects to fly in their direction.

Green Frogs

• Green frogs can grow up to 3 inches long. Their skin is usually green or brown with visible ridges across their backs. Their natural habitat can be in the shallow waters of ditches, ponds, lakes and streams in the Eastern region of the United States. They usually eat tadpoles, spiders and insects. A female green frog can lay as much as 4,000 eggs.

Blue Poison Dart Frogs

• Blue poison dart frogs live in isolated areas of lush rain forests. Their diet consists of beetles, termites and ants. They can also be quite striking because of the bright patterns of their coat. A blue poison dart frog has blue skin with black patches and spots all over its body. While some frogs that belong to this species may also have brighter skin colors with minimal black spots, others may have more black patches that conceal their blue skin. Indigenous people of Colombia and South America dip the tips of their blowgun darts into the frog's skin to kill prey they hunt, according to the National Aquarium of Baltimore website.

Pig Frogs

• Rana grylio, also known as the pig frog, refers to nocturnal frogs that live in the Southeast areas of Texas. In general, pig frogs can grow up to 6 inches long. Their skin color ranges from dark shades of brown to light, olive brown. Most people identify them through their pointed heads as well as the visible dark spots all over their backs. They need to live in large bodies of water, so they usually live in lakes and marshes. Every night, a pig frog may search for prey animals such as small snakes, minnows, crayfish and even other types of frogs. Pig frogs also bear a strong resemblance to bullfrogs, because they can call out while they are on top of aquatic plants or floating on water. The sounds that a pig frog produces gave this species its name, because its calls usually sound like grunting pigs.
