The snail is big, but the snail is small. The most common golden snail is actually the golden snail. The shell color of this golden snail is yellow, while the shell color of the snail is bluish brown. The snail shell of Ampullaria canaliculata shrinks rapidly from the outside to the inside, regardless of the diameter or angle, while the snail shell shrinks relatively slowly.

Ampullaria canaliculata, a mollusk belonging to the genus Ampullaria, is similar in appearance to a river snail, large in size, wide in feeding habits, strong in adaptability, fast in growth and reproduction, high in yield and cheaper than a river snail. There are some cases where unscrupulous merchants pretend to be snails in the market. So, what's the difference between snails and snails? How to distinguish snails from snails?

1, size

The snail is big, but the snail is small. Most snails are 1- 1.5cm. Snails generally grow to the size of grapes, and the size of walnuts is basically the limit. Snails can grow to the size of grapes in one month and walnuts or even eggs in one summer.

Step 2 color

One kind of golden snail is actually a golden snail. The pet aquariums in the market generally sell snails, which are not easy to cross and have no beautiful offspring genes. Snails are often called golden snails and mysterious snails because of their complex species and easy variation. The shell color of this golden snail is yellow, while the shell color of the snail is bluish brown.

3. Shell spiral

The snail shell of Ampullaria canaliculata shrinks rapidly from the outside to the inside, regardless of the diameter or angle, while the snail shell shrinks relatively slowly.

4. Spinal tail

The tail of the snail's spine is long and sharp. The vertebral tail of Ampullaria canaliculata is flat and short.

5, screw cover

Snail shells are round in shape. The snail cover of Ampullaria canaliculata is flat.

6. Difficulties

The snail shell of Ampullaria canaliculata is very fragile, which can be easily crushed by hand and properly broken when it falls to the ground. But the snail shell is hard, not only not fragile, but also difficult to crush by hand.

7, tentacles mouth

The tentacles of Ampullaria canaliculata are thin and long, while those of Ampullaria canaliculata are short and thick. The mouth of Ampullaria canaliculata is slightly petal-shaped and has two "beard"-shaped organs (equivalent to two pairs of antennae), while Ampullaria canaliculata is a cylinder (1 pair of antennae). Snails generally eat food, while snails only suck rocks or glass walls.

Such as the head of a river snail (1 pair of short thick antennae, columnar head)

Such as the head of a river snail (cylindrical mouthparts)

Such as the head of Ampullaria gigas (slender tentacles, split mouthparts)

8. Gas exchange tube

Ampullaria canaliculata sometimes stretches out an extremely long gas exchange tube, which can reach the length of the body, while the snail's gas exchange tube relies on a petal-shaped airbag (a bit like an ear) close to the snail's shell. Therefore, from this perspective, the ability of Ampullaria gigas to deal with dirty water should be stronger than that of snails. Snail/snail prefer clean water system, while snail is not afraid of dirty. Of course, this is only relative.

For example, the head of Ampullaria gigas (the thickest one, and the gas exchange tube extending upward).

9, spawning

You will see that the snail is pink, and it is transparent when it lays eggs around it.

10, snail meat

The flesh of Ampullaria canaliculata is light in color, mostly yellow and white, and the flesh of Ampullaria canaliculata is mostly blue-brown.
