The frog is not a frog, it is only a subspecies of frogs, they still have many differences. Frog body length is usually 70-80mm, male frogs are slightly smaller, while the fowls are a bit stouter than frogs; frogs breed from April to July, and usually start to chirp to attract females before and after the rains and at dusk, while the fowls breed from May to August, and they start to reproduce immediately after hibernation.
A. Is the frog a frog
1. Is the frog a frog
The frog is not a frog, it is just a subspecies of frogs, essentially, the frog and frogs still have a lot of differences, the frog is a kind of frogs similar to the toad, also known as the tiger frogs, and frogs are frogs that have a greenish back color or frogs are frogs with a blue or striped back color.
2, the difference between frogs and frogs
(1) body type
① frogs: body length is generally 70-80mm, and the male frogs to be slightly smaller in length, its head length is slightly larger than the head width, narrow eye spacing, the forelimbs are short, while the hind limbs are short and fat, between the toes is almost fully webbed; it is the back of the epidermis is yellowish-green, dark green, or grayish-green, and the epidermis is also relatively smooth.
② chickens: head than the frog is a little more robust, female chickens head than the male chickens head, body length can be more than 12cm; its throat and chest and gray-brown spots, front and hind limbs have a transverse spot, toes rounded, full webbing between the toes, the front limbs are stout; chickens of the back of the yellowish-green with a little brown, and their ventral surface for the white, there are irregular markings.
(2) Breeding
① Frogs: Breeding period is from April to July, generally before and after the rainfall and at dusk will begin to chirp to attract female frogs, frogs eggs are mostly laid in the rice paddies, early rice fields or other static waters, and occasionally in the slow-flowing water spawning, the eggs generally float on the water surface.
② Field Frogs: Breeding period in May-August, usually immediately after hibernation, they will begin to reproduce, in vitro fertilization in the water, the eggs hatch and become tadpoles, with the different stages of development, the morphological characteristics of the tadpole changes, tadpoles after the development of frogs, and then transferred to the land life.
(3) origin
① frog: mainly distributed in Jiangsu, Zhejiang, Jiangxi, Hunan, Hubei, Anhui, Shandong, Shanxi, Hebei, Sichuan, Chongqing, Guizhou, Fujian and other places.
② Frogs: Shandong, Guangxi, Guizhou, Fujian, Taiwan, Yunnan, Jiangxi, Hainan, Shanghai, Henan and other places are distributed, but also in Southeast Asia and South Asia around the distribution.
(4) food
① frogs: omnivorous animals, the main food rice leaf roller, rice borer, rice borer, stick insects, corn borer, cotton bollworm, ping-pong ash borer, eyebrow mosquito moths, rice eye butterflies, rice mudbugs, rice weevils, tortoiseshell, ladybugs, white-backed ticks, gray-backed ticks, rice blackbugs, brown backed ticks, rice leaf miner flies and so on.
② field fowl: can eat more things, there are spiders, earthworms, polypods, shrimp, crabs, loaches and animal carcasses, etc., at the same time, they will also eat the zephyr frogs, black-spotted frogs and other frogs and small mice, but they are still coleoptera insects as the main prey.
(5) Price
The market price of frogs is relatively low, while the market price of fieldfares is much higher than that of frogs because of the small number of wild ones.
Second, what is the difference between frogs and bullfrogs
1, the difference between frogs and bullfrogs
(1) appearance
① frogs: male frogs body length of 25-27mm, while the female body length of 29-34mm, frogs, the end of the muzzle blunt tip, protruding from the edge of the lower lip, the tympanic membrane is slightly greater than the third finger suction cup. Closer to the eye, no plow bone teeth.
② bullfrogs: body length between 70-170mm, there is a part of the bullfrog, body length up to 200mm or more, the bullfrog's skin is very smooth, no dorsal folds, the muzzle is wide and rounded, the tympanic membrane of female bullfrogs is about the same as the eye and the male bullfrogs are significantly larger than the eye.
(2) Growing environment
①The fieldfrogs: live in paddy fields, ditches, ponds, reservoirs, marshes and other places with water below 900m above sea level, and their habitat will change with different life periods such as foraging, breeding and overwintering.
② Bullfrogs: generally inhabit small lakes and permanent ponds, which have aquatic plants and shallow water made by sediment accumulation, where bullfrogs hide in the shallow water, and they generally breed in river gullies, rice paddies, and still waters with abundant water plants.
2, bullfrog predatory
Bullfrogs can prey on a variety of things, both insects, small shrimp, small crabs and other invertebrates, but also fish, small frogs, tadpoles, salamanders, young turtles, snakes, rodents and other small vertebrates.
3, the bullfrog distribution of the region
Bullfrogs are generally distributed in Sichuan, Chongqing, Guangxi, Hunan, Xinjiang, Yunnan, Zhejiang, Fujian and other places.
4, the value of bullfrog
(1) Bullfrog meat is a high-level health care medicine, a kind of high-protein, low-fat, low cholesterol health food; at the same time, the bullfrog meat also has a very high medicinal value.
(2) The skin of bullfrogs is a high-quality material for musical instruments, a good raw material for tanning, and it can be used to extract high-level exempted gum.
(3) Bullfrog oil can be used to produce high-quality fat; and the pituitary gland of bullfrogs is a highly effective oxytocin; the scraps of bullfrogs can also be made into high-quality feed.
(4) The bullfrogs bred by artificial culture have high economic benefits with fast growth, high yield, low cost and high value.
