The largest frog caught in the world:
The biggest frog in the world is the giant frog in Cameroon, West Africa. African giant frog is the largest frog in the world, belonging to the family Ranidae, and its common name is African giant frog. Appearance characteristics: body length10 ~ 40 cm, usually about 30 cm, weighing about 3 kg, it is the largest frog in the world. The head is wide and flat, the skin is smooth, the hind legs are very strong, the feet are webbed, and he is very good at swimming. The body surface is blue-gray to green with brown markings. Living in forest streams, aquatic, rarely leave the water. Very shy, when disturbed, I immediately dive into the water, so it is not easy to catch. They feed in the water and feed on other vertebrates. The male frog is larger than the female frog and has a larger eardrum. Most of them are distributed in Cameroon and Equatorial Guinea.
In West Africa, tourists often hear legends about giant frogs. But there are different opinions about what the giant frog really looks like. Some say it is as big as a chicken, while others say it is big enough to swallow a chicken; Some people say that there is a deadly poison, and people will be poisoned if they touch it, while others say that it is a delicious food and can be eaten? In order to solve the mystery of the giant frog, 1966, the National Geographic Society of the United States sent Dr. Char and his party on a field trip. Under the guidance of local guides, they finally found the world's largest frog in the tropical rain forest in northern equatorial Africa.
Giant frogs live near rapids or waterfalls in tropical rainforests, and often like to lie still on rocks and wet their skin with water mist from rapids. Do the locals call this frog? Limona? , which means? Mother's son? . Because it looks not only a little like a baby, but also as big as a baby. Its head is like a saucer, and its limbs are as thick as a human wrist. The total length from the mouth end to the toe end is about 0.9 meters and it weighs more than 3 kilograms. There are suction cups at the toe ends of the limbs, which can be attracted to smooth rocks. ? Limona? Hearing is sensitive and inaccessible, but you can't detect what comes from behind. Take advantage of this feature. The locals can catch it skillfully.
How many kinds of frogs are there in the world:
Frogs are also called frog and frog. Frogs are amphibians, with about 190 species. Among them, Rana nigromaculata is widely distributed and has a large number, followed by Rana nigromaculata, Rana chensinensis, Rana tigris, Rana chensinensis, Rana angularis, Rana bullfrog, Rana beard, Rana Emei, Rana harpsichord, Rana flying, Rana maculata, Frog Bufo Rana, Frog Frog Frog Frog, Frog Frog Frog and Frog Frog. Supatar golden frog, red frog, narrow-mouthed frog, Pangu toad, brown tree frog, face-faced tree frog, Zhuluo tree frog, orange-bellied tree frog, Mohs tree frog, emerald tree frog, Taipei tree frog, Chinese tree frog, Gongde red frog, Swanhao red frog, Gushi red frog, Ladushi red frog, belly-spotted frog, light rain frog.
Frogs are amphibians, with about 190 species.
There are 73 species of arthropoda, which are distributed in sub-Saharan Africa. Small to medium-sized terrestrial frogs develop directly.
225 species of Ranidae, distributed in Africa, small to medium-sized arboreal species, tadpoles aquatic.
Ranidae, also known as Ranidae, is generally small in size. Widely distributed in temperate and tropical regions of all continents, except Antarctica and most parts of Australia. * * * There are more than 280 species of 6 1 genus, and there are four species of one genus in Taiwan Province. The outlet hole of the tadpole of Ranidae is located in the lower center of the abdomen, with no beak or horny teeth, which is different from other frogs and is a specialized type.
Ranunculaceae, except Australia and most parts of South America, are found all over the world. There are about 47 genera and 677 species, but there are still many differences in the classification of genera. Some scholars have subdivided Rana into many genera, which are not used here for the time being. Therefore, there are 14 species of a genus in Taiwan Province, among which bullfrog is an exotic species recently introduced.
Tree frogs are mainly distributed in tropical regions of Africa and Asia, so they are also called old world tree frogs. * * * There are 10 genus 190 species, and there are four genera and ten species in Taiwan Province. Tree Ranidae is an arboreal species, the finger (toe) end expands into a sucker, and there is Y-shaped cartilage in the sucker, and there is interstitial cartilage between the last two sections to facilitate climbing on the tree.
Among them, Rana nigromaculata is widely distributed and has a large number, followed by Rana zewalskii, Rana money and Rana tigris.
Rana nigromaculata: The body length is about 70-80 mm, the male is slightly smaller, and the head length is slightly larger than the head width.

The skin is smooth, with a pair of dorsal folds on the back, and 4-6 rows of irregular short skin folds between the two dorsal folds. The back is yellow-green, dark green or grayish brown, with irregular black spots of different numbers, black horizontal spots on the back of limbs, and smooth fish-white skin on the ventral surface.

Xenopus laevis, scientific name? Golden frog? In fact, it is the trade name of its albino color change. Because there is no tongue, we can only use its forelimbs to stir invertebrates in the water. It is distributed from the savanna of South Africa to Kenya in the north and Cameroon in Uganda in the west. Body length100 mm. The male will be smaller than the female, and the hind limbs have three pairs of horny claws. As a completely aquatic species, it lives widely in fresh water, especially in still waters. Most of them hide in the depths of the water during the day and climb to the shallows at night. The breeding period is from early spring to late summer, and the female frog can lay more than 2000 eggs per fetus.
The African giant frog may be the biggest frog in the frog family. An adult male frog weighs 3 kilograms and is about 30 centimeters long. If his legs are pulled apart, his length can reach 1 meter. It is said that only Suriname? Beafa marini? Toads can be compared. However, this rare frog is in danger of extinction, and its name has been on the red list of endangered species prohibited from international trade by the Washington Treaty.
