The world is big, there are no wonders. Have you ever seen a flying frog? In the tropical forests of southeast Asia, India and China, there is a different kind of tree frog that can glide through the forest, and people are accustomed to calling it a flying frog.
The appearance of flying frogs is not the same as the frogs and toads we usually see, the fingers and toes of their limbs are large and long, and the ends are expanded to become suction cups, through the thin transparent suction cup skin, we can see that between the two bone nodes at the ends of the fingers and toes, there is a "y" shaped cartilage. The frog uses large suction cups on its fingers and toes to attach to the trunk and branches of trees to climb lightly and will not fall to the ground.
Frogs have a very developed web membrane between their fingers and toes, when the fingers and toes are extended, the webbed membrane opens to an area of about 30 square centimeters, and can fly tens of meters away from the sliding period between two trees, and they can even move several meters away by jumping on the flat ground. Or land safely from a tree like a man on a plane with a parachute.
When gliding and flying, the frog's hind toes not only assist the forelimbs to shoot the air for flight, but also play the role of a rudder, as long as the hind limbs are moved, it can fly in another direction at will. The frog also has a flying trick, before flying, it will inhale a lot of air to inflate its body in order to achieve the best gliding effect.
With the exception of the flying frog, which is a gifted frog, most frogs have well-developed limbs, particularly long hind limbs, and are good at jumping, and their vertical and horizontal bounce distances are usually 10 and 24 times their body length. For example, the rain frog has an extraordinary jumping ability, jumping effortlessly from one tree to another in the woods.
Poison dart frog, when you encounter it, retreat
In fact, among the surviving amphibians, the most successful is the frog. Not only are they the most diverse, but they are also widely distributed. Most frogs are extremely adaptable, and can be seen from high mountains to depressions. There are about 200 kinds of frogs in China, including some extremely rare frogs, such as the tiger striped frog of the national second-level protected animal.
The tiger striped frog, also known as the water chicken, is large and stout, and the female is larger than the male. The female frog is about 12 cm long and weighs up to 250 g, making it the largest type of frog that lives in rice paddies. This frog as a whole is yellow-green with a dark pattern, which is somewhat similar to that of a tiger.
In China's Emei Mountain there is also a kind of frog called horned frog, as the saying goes, from the heart, this sentence is also applicable to the horned frog, just look at its appearance, there are horns on the head to see is not good lord. The horned frog has a short and fat body, and there are horn-like protruding pieces of flesh near the eyes, which are fierce, no matter what it is, as long as it bites, it will not easily release.
The Chinese forest frog, also known as the earth borer, is a famous medicinal frog. Its back is earth-gray with yellow and red dots and a dark triangular class at the eardrum. Forest frogs live in the trees on the slopes of northern China. Their dried bodies and female frog fallopian tubes can be made into "clam toad oil", which can cure fatigue cough and so on.
Have you ever considered why frogs call so loudly? Most frogs can make a loud cry because underneath the frog's mouth, there is a special tissue that can retract the air. When air is released, it emits a chirping sound through the vibration principle. Different frogs have different volumes of their calls. Even frogs of the same breed may make different calls.
Of course, there are exceptions to everything, and not all frogs need to expand and contract their own "vocal tissue" to make sounds, there is a frog called a mountain clam, which does not need to expand its own "vocal tissue" in the process of singing.
The bullfrogs in the frog species have the highest song in the frog world, and their collective chirping sound can even travel three kilometers or more. In the rainforests of South America, there is a tree frog called the Cochi frog, which is a small frog, only the length of a small finger, but the song is unusually loud. Scientists have found through measurements that their chirping can even exceed 100 decibels.
Most frogs make chirping calls that are used during mating and courtship. Scientists have found that many female frogs can distinguish which male frogs are "strong" through their calls, and mate with them, so as to ensure the continuation of the excellent genes of the entire population, the weak and the strong, the survival of the fittest, which is the most real nature.
Among frogs, different species of frogs may vary greatly in size, mentioning large frogs may not be unfamiliar to you, common bullfrogs, of course, there are larger frogs than bullfrogs, that is, the African Cameroonian giant frog, it is the largest frog in the world, with a body length of more than 30 centimeters.
Since there is the largest frog, there must also be the smallest, and the smallest frog in the world is the Ama utong frog, with an average body length of only 7.7 mm. It is found in Papua New Guinea, an island nation in the western South Pacific. If you put the largest and smallest frogs together, it is really interesting to think about.
