Frog family is a general term for a class of organisms, they all have common characteristics, with smooth and moist skin, strong hind limbs, and slender waist, etc., the world's frog family has a total of about 50 genera and 670 species, the smallest known frog is the Ama Utong frog, the body length is only 7.7 mm, there is no small fingernail cover large, and the largest frog is the protagonist to be introduced today, weighing 6 pounds of giant harmonic frog, also known as "African giant frog".

Frogs are a relatively widely distributed amphibian in the world, from high mountains to basins, from the tropics to the cold zone, in addition to Antarctica, even the southern edge of the Arctic Circle has traces of frogs, and two-thirds of the world's frogs are concentrated in Asia, so frogs are very common in our impression.
However, the giant harmonic frog this "African giant frog" can be much more mysterious, this frog is currently known to be the world's largest frog, body length of 30 cm, thick hind limbs extended, the entire frog body can be close to 1 meter long, plus about 6 pounds of body size, looking at those unknown regions in the world, the possibility of reaching this heavyweight is very small.
Giant harmonic frog has very high requirements for the environment, this large frog currently only survives in the tropical rainforests of southern Cameroon and northern Equatorial Guinea, the average temperature here is maintained between 25-29 degrees Celsius for a long time, and the giant harmonic frog likes to live in a large river with fast water flow and clear water, only such a stream can guarantee a rich oxygen, and this harsh living conditions are also doomed to the living space of the giant harmonic frog is very small.
Look at the world's largest toad sea toad next door, that is another world, invading Australia, the population has expanded sharply to 200 million, there is a great situation to conquer the whole of Australia, not only to see what to eat and what to eat, there is a high poison, only a very small number of predators can threaten it, the vast majority of predators see it to hide, there is no way.
Giant harmonic frog basically only at night out of activity, very afraid of heat they will be soaked in cool water almost the entire day, the outside temperature as long as more than 23 ° C is not conducive to the growth of giant harmonic frog, in Africa, which is known for its high temperature, can have a perennial 23 ° C habitat is really going to find a place, but maybe the temperature in Africa is very low, otherwise how can there be Africans who come to Chongqing will shout heat stroke to return to Africa to escape the heat?

As the nature of amphibians, the vast majority of amphibians' reproductive strategies are to win by quantity, and will produce thousands of eggs during the breeding period, and then let these eggs survive on their own, good luck can hatch and grow, bad luck will not worry too much, after all, the base is there, there will always be "fish that slip through the net".
But the giant harmonic frog is different, the breeding period of the giant harmonic frog in July, August or December, January of the following year, before each breeding, the female macroharmonic frog will choose in advance away from the rapids of the depression, after finding a suitable depression, the macroharmonic frog will clean up the leaves and debris in the depression, if there is no suitable depression, the macroharmonic frog will even carry stones to stage the water flow, so scientists speculate that the reason why the macroharmonic frog will grow to such a huge size may be related to the ability to carry heavy objects.
After building the nest, the giant harmonic frog produces hundreds of eggs with a diameter of about 3.5 mm at a time, and guards these eggs for the next 3 months to hatch, this cub protection behavior is also rare in amphibians, the giant harmonic frog is large, its tadpole is also large, the average tadpole can be the size of a goose egg, holding it in the hand like a carp.
In addition, the courtship of the giant harmonic frog is also very peculiar, the general frog calls the mate by drumming the air into the vocal sac to pronounce it, while the giant harmonic frog does not use such a complicated way, they directly open their mouths to make a call, and the female decides who is "Ruyi Langjun" according to this call.

In addition to conventional crocodiles and snakes, there are basically no animals that can threaten their survival, and because of the huge size of the food, the giant harmonic frog also plays the role of a hunter to catch some small animals, such as mosquitoes this "snack", only relying on them is really not enough to "plug the teeth".
But the giant harmonic frog and all animals on the earth, the thousands of calculations do not count the existence of humans, the beginning of the nightmare of the giant harmonic frog is after humans feel good taste, since then the giant harmonic frog has been served on the table as a delicious ingredient, for humans, the huge size of the frog makes it easier to be caught, and limited to physical fitness, jumping seven or eight times will have no strength.
At the end of the 20th century, macrotuneal frogs can be easily seen, but today, their tracks have been very difficult to find, there was a French journalist in order to take photos of this giant frog, searched in the rainforest for 4 months, and the huge size of the macrotuneon frog has also become the star animal of the reptile market, in the local market a 6-pound macrotune frog can buy 2,000 CFA francs, about 4 US dollars, like a larger macrosonal frog can sell for 8,000 CFA francs, and in Equatorial Guinea, Ordinary people earn only about $2 a day, and a giant frog can top a week's income, which shows how attractive it is to the locals.
At present, the "World Union for Conservation of Nature" has listed the giant harmonic frog as an endangered species, and the government of Equatorial Guinea has also set an export limit of 300 per year, but with the expansion of human activities and the destruction of the environment, the temperature of many streams in the place where the giant harmonic frog lives has increased by as much as 5 ° C compared with the past, and the future survival path of the giant harmonic frog is very unoptimistic.
