The difference between frogs and frogs

Frogs are amphibians of the family Anura, which are divided into many kinds. The common ones are black spotted frog, bullfrog, tiger striped frog, and so on, and the frog is tiger striped frog, which means that the frog is a kind of frog. Our common frog is black spotted frog, black spotted frog and tiger striped frog are very similar, it is not easy to tell the difference. Let's take a look at the differences between them.

Morphological differences between frogs and frogs

1. Frogs: the body length of the frog is about 70-80mm, the male is slightly smaller, the head length is slightly longer than the head width, the kiss is obtusely round and slightly pointed, the kiss edge is not obvious, the distance between the eyes is very narrow, the forelimb is short, the batch tip is obtuse, the hind legs are short and fat, the tibial joint reaches the eye, the toes are almost fully webbed, and the epidermis on the back is yellowish green, dark green or grayish green, and the epidermis is relatively smooth.

2. The pheasant is burly and sturdy, the female is larger than the male, the body length can be more than 12 cm, the weight is 250-500 grams, the skin is rough, there are dark irregular markings on the head and side of the body, the back is yellowish green and slightly brown, there are more than ten rows of longitudinally arranged skin edges, the skin edges are scattered with small warts, the ventral surface is white, there are also irregular markings, there are gray-brown spots on the pharynx and chest, horizontal spots on the front and back legs, and round toes. The toes are fully webbed, the forelimbs are stout, the finger pads are well developed and gray, and the male frogs have a pair of external vocal sacs.

Reproductive differences between frogs and frogs

1. Frogs: the breeding period of frogs is from April to July, and the best part of spawning is in April. It usually begins to sing before and after rain and at dusk to induce female frogs to hold and lay eggs in rice fields, early rice fields or other still waters, and occasionally lay eggs in slow water. Each egg piece has 2-3.5 thousand eggs, mostly floating on the surface, 1.7-2.0 mm in diameter, heavy tadpole, weak tail muscle and well-developed caudal fin. The end of the tail is sharp and round, and the metamorphosis is completed in more than 2 months.

2. Pheasant: the breeding period of pheasant is from May to August. After waking up from hibernation, the pheasant will immediately carry out breeding activities, carry out in vitro fertilization in water, and become tadpoles after hatching, with a series of larval characteristics adapted to life in water. And with the different stages of development, the morphological characteristics also change. Tadpoles develop into frogs after metamorphosis, and then transfer to live on land. The life history includes three stages: eggs, tadpoles and frogs.

The difference of producing area between frog and frog

1. Frogs: frogs are mainly distributed in Jiangsu, Zhejiang, Jiangxi, Hunan, Hubei, Anhui, Shandong, Shanxi, Hebei, Sichuan, Chongqing, Guizhou, Fujian, Guangdong, Heilongjiang, Jilin, Liaoning and Inner Mongolia.

2. Pheasant is widely distributed in Jiangsu, Zhejiang, Hunan, Hubei, Anhui, Guangdong, Guangxi, Guizhou, Fujian, Taiwan, Yunnan, Jiangxi, Hainan, Shanghai, Henan, Chongqing, Sichuan and southern Shaanxi. It is also found in South and Southeast Asia abroad.

Differences in feeding habits between frogs and frogs

1. Frogs: frogs are omnivorous animals, of which plant food accounts for only about 7% of the diet, and animal food accounts for about 93% of the diet. The main foods are rice leaf roll, rice borer, rice bract insect, armyworm, corn borer, cotton red bollworm, gray borer, eyebrow mosquito night moth, rice eye butterfly, rice negative mud worm, rice weevil, beetle, ladybug, white-backed planthopper, gray-backed planthopper, rice black bug, brown-backed planthopper, rice leafminer, duckweed, fruit fly, mosquito and so on.

2. Pheasants: there are many kinds of food for pheasants, mainly on Coleoptera insects, accounting for about 36% of the food, and others include spiders, earthworms, polypods, shrimp, crabs, Loach and animal carcasses. It is hard to believe that it also eats frogs such as frogs, black spot frogs and mice, and they play an important role in the food of tiger frogs.
