The Benefits of Frogs

Frogs and toads eat billions of insects each year making them a valuable asset to any area they can be found. They also provide a critical food source for snakes birds fish and a lot of other types of wildlife. Another very important role of frogs is they are a environmental indicator. They are often the first species to show signs of a problem with the environment, pollution or any other changes in the local ecosystem.

The frogs skin is covered with many types of protective toxins. Some are good for preventing the frog from being eaten by predators, while others are as a protective layer from fungus or bacteria. Many of said toxins are currently undergoing research to determine the viability of them being used for drugs in people. Most of the frogs external chemicals and toxins have quite an effect on humans. The chance for groundbreaking medical breakthroughs are great with these chemicals.

On this website you will find many different species of this great amphibian. Some are poisonous, some are huge and some are your local variety. They are all similar, yet very different in many ways.

I tend to concentrate mostly on various species of tree frogs on this site, especially the poisonous types, but each day our list of frog information grows larger and we do have a large variety of all types of these amphibians.

Frogs are one of the greatest animals on the planet. Archie Carr once said “Frogs do for night, what birds do for the day: They give it a voice. And the voice is a varied and stirring one that ought to be better known.” Frogs were the first animals on land that evolved vocal cords. They have had a voice around 180 million years! Some of these amphibians with the greatest singing voices tend to be various species of tree frogs. There are over 5000 different types of frogs in the world that we know about, there are likely a lot more. Considering the habitat that most frogs live in they can be hard to locate, the Amazon Jungle has tons of different species. New research, which is based on reconstructing  family trees for hundreds of varying frog species from around the world, revealed that the frogs in the Amazon rain forest have been around for millions of years longer than the earliest tree dwelling species in other locations. So they have had a lot more time to evolve and diversify, leading to a concentration of various frogs in that relatively small area.

How Frogs Sing

 Air Flow in a Frog During Calling

Many Male frogs have vocal sacs (as shown in the image) These sacs resonate sounds similar to megaphones. It is common for the chirping of a male to be heard up to a full mile away! This calling is what will attract females for breeding. You can always tell when spring has sprung, by the sound of frogs and toads chirping away in the swamps and other wetlands.

 

Frog Anatomy

The frogs skeleton differs from most animals. They lack rib bones, they don’t have a neck and cannot lower their heads. They have a pelvis that slides up and down the spine. This pelvis is thought to help the frog jump.  Most frogs have 4 toes in the front and five on the back feet. The length of these toes will differ greatly between frogs.The toe length and bone structure is determined by whether or not the frog needs to climb and grip trees. Tree frogs will have much longer toes than a water dwelling variety.

The frogs bone structure is not terribly different than a humans, especially the toes and leg bones. The collarbones are also shaped similar to the same bones in a person’s body.
