Belgian biologist George Borenger discovered a giant frog in 1906 while investigating primeval forests in the wild, which feeds on insects, crustaceans, fish and molluscs, and if necessary, small mammals such as salamanders, small frogs and mice, and amphibians.
Local blacks would also catch the frog, roast it on a fire, cook it and eat it as food. Borenger later named it GiantSlippery Frog, the African giant frog. Years later, the African giant frog was identified as the world's largest frog. It is said that the giant frog is 17~32 cm long and weighs 1~7 pounds, and if you straighten your feet, you can reach one meter. In addition, the African giant frog, which adults can't grasp with one hand, its tadpoles are also quite large. And this frog has extremely high bouncing ability, can jump to more than 5 meters high. But the endurance is not good, and after jumping six or seven times, I can't jump.
In the 80s, the United States imported a large number of giant frogs from Africa to compete in the "high jump". Most of the giant frogs died on the road due to their long distances. Even if they go to the United States, they die quickly because of the disobedience. While international transactions are now banned, there are still some illegal transactions that take place in secret.
Don't think that its huge size is particularly survivable. On the contrary, it is extremely demanding on the environment, can only live in the tropical rainforest where the water is turbulent, the waterfall is gushing, the water should be very clean and clear, the water temperature is between 16~23 degrees, and there is plenty of food around. And reproduction can hardly be carried out elsewhere. Hundreds of eggs are laid at once, and the diameter of the eggs is about 3.5 mm. After the female frog lays eggs, the male African giant frog comes out to fertilize it.
During this time, female African giant frogs also built their nests specifically to protect their offspring. The river moss is eaten when the frog eggs are finished incubating and then grows about 5 cm long over 90 days. This period is also the hardest time for the African giant frog, as it always protects the defenseless tadpoles from harm. Even when foraging outside the nest at night, African giant frogs usually move around to observe. Prevent its offspring from being eaten without being in danger. Animals are not the African giant frog's worst enemy, humans are.
For decades, due to the arbitrary destruction of primeval forests and rivers, the habitat of the African giant frog has been greatly reduced, and its living environment has been severely damaged. Africans often catch giant frogs in their homes as a delicacy. Eating African giant frogs has become fashionable in major towns such as the local area, and is popular at banquets and weddings, and African giant frogs can be sold in addition to eating. An African giant frog can sell for $8 for 6 pounds, and if it's bigger and heavier, one can fetch about $15.
The destruction of the environment, combined with human predation, has caused the African giant frog population to plummet. According to statistics, African giant frogs were still everywhere at the end of the 20th century. But after the 21st century, it will take a long time to take pictures of the life of the African giant frog. For this purpose, the IUCN has also listed the giant frog as an endangered species. In this case, humans have established national parks to protect their natural habitats, and sent biologists to African giant frogs for conservation work and artificial breeding. The local government has imposed an export limit of 300 birds a year to prevent the smuggling of African giant frogs. But this policy is not ideal, because most of the people who eat African giant frogs are local compatriots!
