How does a bullfrog digest animals, is his stomach so big?

First of all, the size of the bullfrog is clarified, the bullfrog can grow very large, up to the size of a chicken. The adult body is generally between 70 and 170 mm long, and the maximum can be more than 200 mm, making it one of the largest frogs. As a result, bullfrogs can feed on larger creatures.

Food has a digestive process: probably the bullfrog feeds, swallows through the esophagus, enters the stomach and intestines, and the peristalsis of the digestive tract plays the role of stirring and mixing, and the digestive enzymes in the digestive juice are digested, and this process is accompanied by chemical reactions.

Bullfrogs are native to North America.

It is a member of the list of invasive alien species in China, including Sichuan, Chongqing, Guangxi, Hunan, Xinjiang, Yunnan, Zhejiang, Fujian, etc. Its meat is delicate, delicious, nutritious, has certain medicinal value, and is the main breeding species of edible frogs in various places.

Bullfrogs are cultivated on a large scale in Fujian, Guangdong, Zhejiang and other coastal areas in China, and the aquaculture output is increasing year by year. The domestic processing of bullfrog series products can be achieved with the characteristics of good concealability, nutrition and convenience. It is more and more in line with the increasing requirements of people's life rhythm and the increasing requirements for food nutrition, convenience and fast food.

Bullfrogs prey on invertebrates.

Such as insects, small shrimp, small crabs, etc., small vertebrates, such as small fish, small frogs, tadpoles.

Salamanders, hatchlings, snakes, and rodents eat a lot.

The bullfrog digests animals, and its stomach is the result of adapting to its feeding habits, and its stomach is divided into four parts: cardia, fundus, gastric body and pylorus.

The cardia is the part of the stomach that connects to the esophagus, and this part is made up of sphincters that control the backflow of food. The fundus of the stomach is rich in glands, and the digestive juices secreted contain chemicals such as proteases and hydrochloric acid, which are used to digest food. The pylorus connects with the small intestine to complete the digestion and absorption of food.

In summary, bullfrogs digest animals by secreting a variety of chemicals while using the muscles in their stomach to control the flow of food.

Don't get me wrong, bullfrogs are different from frogs, frogs are indiscriminately caught by humans and are on the verge of extinction, bullfrogs are overflowing, listed as invasive alien species, bullfrogs were originally introduced by some people to breed as ingredients, there are many farms that breed bullfrogs, many restaurants have boiled bullfrogs, a bullfrog is almost the size of a chicken, nutritious, delicious.

Bullfrogs are greedy by nature and eat heavily during the growing season. When feeding with bait trays, groups compete for the upper plate, and the weak, small ones are often squeezed out of the plate. The maximum stomach volume of a bullfrog can be up to 10 times that of an empty stomach.

Bullfrogs are naturally **, and it often happens that large frogs eat small frogs, and they can also swallow snakes. Bullfrogs can eat and are hungry tolerant, and when there is an extreme lack of food, the level of metabolism of bullfrogs will naturally decrease.

The bullfrog has a green or brown body with a white to pale yellow belly and black stripes on its limbs. It is about 20 cm (8 inches) long and 25 cm (10 inches) long on its hind limbs. Adults weigh more than 1 kilogram (1 pound).

Lives in or near still water. Breeding in spring, eggs are laid in water. Tadpoles are greenish-brown in color with dark spots.

The tadpole stage lasts 1 to 3 years and is determined by climatic conditions. Many bullfrogs are edible or used as experimental material.

After the bullfrog ingests and swallows, the food enters the human stomach and intestines through the esophagus, although the peristalsis of the digestive tract helps mechanical digestion and plays the role of stirring and mixing, but it mainly relies on the role of digestive enzymes in the digestive juice for chemical digestion. The final products of food digestion are amino acids that are dissolved in water.

glycerol, fatty acids, and glucose.

Such nutrients are mainly in the elongated, surface area.

The large and small intestines are absorbed by the intestinal wall, and then enter the human capillaries or lymphatic vessels, and are transported to the tissues and organs of the bullfrog's body through blood circulation for growth and development and energy consumption. Undigested food residues in the stomach and small intestine enter the human intestine and reabsorb part of the water contained in them, forming feces, and finally passing through the cloaca.

and its opening hole to be excreted into the body.

Bullfrog tadpoles feed mainly on green algae in water.

Phytoplankton such as diatome, or small other aquatic plants, also eat small zooplankton. its digestive system.

It is significantly different from the carnivorous adults, that is, the digestive tract of bullfrog tadpoles is long and coiled, and it is particularly developed.

The digestion process of food: after the bullfrog ingests and swallows, the food enters the human stomach and intestines through the esophagus, although the peristalsis of the digestive tract helps mechanical digestion and plays the role of stirring and mixing, but mainly relies on the role of digestive enzymes in the digestive juice for chemical digestion.

Nutrient absorption: The final products of food digestion are amino acids, glycerol, fatty acids and glucose dissolved in water. In this way, nutrients are mainly absorbed by the intestinal wall in the small intestine with a slender and large surface area, and then enter the human capillaries or lymphatic vessels, and are transported to various tissues and organs of the body of the bull wheel frog through blood circulation, as a pre-wax let for growth and development and energy consumption.

Excretion: Undigested food residues in the stomach and small intestine, after entering the human intestine, reabsorb part of the water contained in it, form feces, and finally excrete into the body through the cloaca and its opening.

Bullfrog tadpoles mainly feed on phytoplankton such as green algae and diatoms in the water, or small other aquatic plants, and also eat small zooplankton.

Its digestive system is significantly different from that of carnivorous adults, that is, the digestive tract of bullfrog tadpoles is long and coiled, and it is particularly developed.

<>1. The food ingested and swallowed by bullfrogs will pass through the esophagus into the stomach and intestines of bullfrogs, and bullfrogs rely on the mechanical digestive peristalsis of the digestive tract and the digestive enzymes in the digestive juices for digestion. 2. The nutrients produced by the bullfrog after digestion will be absorbed by the intestinal wall in the small intestine, passed into the capillaries and lymphatic vessels of the bullfrog, and transported to the various body organs of the bullfrog in the way of blood circulation. 3. The indigestible food residues in the small intestine of the bullfrog will be passed into the large intestine, and the large intestine will absorb part of the water in the food residue to form the feces of the bullfrog, which will be discharged to the body through the cloaca and its opening.

1. How do bullfrogs digest food

1. The bullfrog feeds and swallows it, and the food ingested into the body will pass through the esophagus into the stomach and intestines of the bullfrog. Bullfrogs rely on mechanical digestion in the digestive tract, peristaltic movements, and digestive enzymes in digestive juices for digestion.

2. The products after the digestion of bullfrogs are amino acids, glycerol, fatty acids, glucose, etc., which can be dissolved in water. These nutrients will be absorbed by the intestinal wall in the small intestine, and passed into the capillaries and lymphatic vessels of the bullfrog, and transported to the various body organs of the bullfrog in the way of blood circulation, ensuring the growth and development needs of the bullfrog.

3. The indigestible food residues in the small intestine of the bullfrog will be passed into the large intestine, and the large intestine will absorb part of the water in the food residue to form the feces of the bullfrog, which will be discharged to the outside of the body through the cloaca and its opening.

2. What do bullfrogs generally feed on?

1. What do bullfrogs generally feed on?

Bullfrogs generally feed on invertebrates such as insects, small shrimps, and small crabs, as well as small vertebrates such as small fish, small frogs, tadpoles, salamanders, young turtles, snakes, and rats. Tadpoles are the larvae of bullfrogs, which generally feed on plankton, algae, rotifers, larvae of insects, mosses, and aquatic plants.

2. Key points of bullfrog breeding.

1) The character of the bullfrog is relatively high, and there are often frogs eating frogs, and the bullfrogs should be raised in groups according to the size when they are artificially raised, and try not to let them eat the same kind.

2) Bullfrog juveniles are suitable for survival at a temperature of 25 -30, once the temperature exceeds 30 or is lower than 12, it will cause adverse effects on bullfrogs, including decreased appetite, growth stoppage, and even heat or freeze to death in severe cases. In the summer, when the temperature is high, the water in the frog pond can be replaced to achieve the purpose of cooling, and in the winter, when the temperature is low, plastic greenhouses can be built, and geothermal water can be used to achieve the purpose of heat preservation.

3) To ensure that the growth environment of bullfrogs is clean and hygienic, regularly clean up the leftover bait, and scrub the places where they feed. Carefully observe the bullfrogs in the breeding pond, once there are sick or dead bullfrogs, they should be taken out in time to ensure that the frog pond is clean and clean.
