The difference between bullfrog and frog

Many people cannot tell the difference between bullfrogs and frogs, but in fact, there are huge differences between bullfrogs and frogs. Apart from external factors such as different appearances, the biggest difference between bullfrogs and frogs is that bullfrogs are edible, but frogs are not. This summary is easier to understand. I believe that after understanding the following content, it will be easier to distinguish between bullfrogs and frogs.

The bullfrog is native to North America and is a large edible frog second only to the African stream frog. It is named bullfrog because its croaking sound is loud and resembles a bull's mooing.

Bullfrogs are very nutritious and delicious, and are loved by people.

Bullfrogs are very nutritious. According to analysis, every 100 grams of bullfrog meat contains 19.9 grams of protein and 0.3 grams of fat. It is a high-protein, low-fat, extremely low-cholesterol food that tastes delicious.

Bullfrogs also have the effects of nourishing, detoxifying and treating certain diseases. Medically speaking, when people (especially women) are on a diet, eating frog meat can stimulate the appetite. Frog meat is most suitable for patients with weak stomachs or excessive stomach acid.

The skin of bullfrog can be made into leather, which is made into high-end gloves and elastic ties, and is very popular among consumers.

Its skin can also be used to make hide glue, which is used as glue on jewelry, diamonds, jade and other decorations.

Its waste products such as bones, heads, internal organs, limbs and feet can also be processed into feed for fish and livestock.

Frogs are not edible: this is because frog meat contains Desmodium meningitidis, a white thread-like parasite that can damage local human tissues and may even cause blindness if eaten. In addition, when chemical fertilizers are applied in farmland, some pesticides accumulate in the bodies of insects. Frogs that swallow these insects will also be infected with the pesticides. If people then eat the poisoned frogs, they can easily get poisoned.

Difference: The most obvious difference between bullfrogs and frogs is their mouths, and the two frogs are easy to distinguish.

Among frogs, there is a kind of tiger frog, which is distributed in Asia and most parts of my country. Individuals are large, with a body length of more than 12 cm and a weight of about 250 g. Their appearance and body color are similar to those of bullfrogs, but their morphological characteristics are obviously different.

(1) Bullfrogs are particularly large, with adult frogs weighing up to 1,500 grams and being more than twice as long as tiger frogs.

(2) The skin on the back of the bullfrog is relatively flat and has no skin folds; the skin on the back of the tiger frog is rough, with dark stripes on the body and obvious horizontal stripes on the limbs. This is the main difference between the two.
