The life spans of frogs in the wild are widely unknown, but likely range from one day to 30 years. In captivity, frogs have been known to live more than 20 years.
#7:Paedophryne Amanuensis — The Frog Species With the Shortest Lifespan.
Frogs can take up to four years to develop to full maturity. An adult frog can reach up to 13cm in length and can vary in colour from green to brown, and even red or yellow.
Mayfly. The mayfly is a small, winged insect that is found all over the world. It has a lifespan of only 24 hours, it is known for being one of the shortest living animals in the world. Mayflies are known for their short lifespans and their ability to mate in mid-air.
Glass sponges (Hexactinellida) are animals that live 10,000 years. Some scientists think that some glass sponges survive up to 15,000 years. Not only are glass sponges the longest-lived animal on earth, but they're also one of the oldest animal types.
They cannot be stopped but it is possible to slow the rate of these processes. This can be done by changing one's lifestyle (diet, exercise, etc). The science of aging is not yet fully understood; therefore, it is difficult to determine an absolute limit of 200 years.
"The oldest frogs overall are roughly 250 million years old from Madagascar and Poland, but those specimens are from higher latitudes [than the Chinle frog] and not equatorial." The discovery of the Chinle frog may also be a sign of things to come.
The oldest frogs ever discovered have been unearthed in rocks from Madagascar and Poland, dating back roughly 250 million years.
Some have tiny teeth on their upper jaws and the roof of their mouths while others sport fanglike structures. Some species are completely toothless. And only one frog, out of the more-than 7,000 species, has true teeth on both upper and lower jaws.
Flexi Says: Frogs may not sleep like humans but they do have periods of rest during which they tuck their limbs under their body, cover their eyes with their nictitating membrane and stay immobile for long periods of time.
Frogs Can Experience Oxytocin Increases – AKA Happiness
Like oxytocin in humans and other animals, mesotocin in frogs helps these amphibians feel content with their environment and not be stressed.
In fact, among the amphibians, the anurans, or frogs and toads, are perhaps the most intelligent, and have the largest brain to body ratio of the amphibians.
While the life spans of frogs in the wild are unknown, frogs in captivity have been known to live more than 20 years. There are over 6,000 species of frogs worldwide.
The little grass frog is the smallest frog in North America. It is relatively slender with long legs, small toe pads and a pointed head. The little grass frog can be tan, reddish, greenish or pinkish, and its pattern is variable.
Argentine palaeontologists have uncovered fossilized remains of a rare species of frog that lived two million years ago, the science and technology agency at the La Matanza national university said Monday.
Some say that their name refers to the fact that amphibians live in two places- on land and in water. Others say their “double life” refers to their two distinct life stages – a larval and an adult stage. There are more than 6,000 species of amphibians living today.
“Frogs have been around for well over 200 million years, but this study shows it wasn't until the extinction of the dinosaurs that we had this burst of frog diversity that resulted in the vast majority of frogs we see today,” said study co-author David Blackburn, associate curator of amphibians and reptiles at the ...

Triadobatrachus massinoti, the world's first frog
About 250 million years ago, long before the arrival of the dinosaurs, a ten-centimetre-long amphibian with a flat, compact body emerged on the supercontinent Pangaea. Unlike its salamander-like ancestors, it only had a small tail supported by six vertebrae.
earth: 'The purple frog's lineage is 120 million years old. It has seen Earth itself evolve' | India News - Times of India.
Aubrey de Grey is one of the world's leading – and most talked-about – biomedical gerontologists. Meet the man who believes that the first person to live to 1,000 years of age has already been born. Aubrey de Grey is one of the chief proponents of research utilising genomics to explore longevity.
Scientists have found a way to lengthen worms' lives so much, if the process works in humans, we might all soon be living for 500 years. They've discovered a "double mutant" technique, when applied to nematode worms, makes them live five times longer than usual.
