CATDOLL : CATDOLL: How many teeth does a snail have? Microscope

1. How many teeth does a snail have?

1. 25,600 pcs.

2. Snails refer to all terrestrial species of the class Gastropoda. Generally, Western languages ​​do not distinguish between aquatic snails and terrestrial snails. In Chinese, snails only refer to terrestrial species, while the broad definition of snails also includes giant shield slugs. Snails are an animal that includes many different families and genera. They feed on plants and lay eggs in the soil or on trees. They are more common on tropical islands, but some also live in cold regions.

2. Snails have more than 26,000 teeth. Are they the insects with the most teeth in the insect kingdom?

It is understood that snails are indeed the animals with the most teeth in the world. Although its mouth is about the size of a needle tip, it has 25,600 teeth. There is a small hole a little bit below the middle of the snail's tentacles. This is its mouth, and there is a serrated tongue inside, which scientists call "radula". Snails have a very wide range of foraging, and their staple food is various vegetables, weeds and melon and fruit peels; leaves, stems, buds, flowers, and juicy fruits of crops; all kinds of green grass and green plant feeds, juicy feeds, bran feeds, and cake feeds. Snails feed by mouth. The teeth of snails are very small and almost invisible. If there are few of them, it is inconvenient to eat. In fact, this is the evolution of organisms in the face of nature. In order to survive, they need to adapt to the environment. The teacher introduced some life knowledge of snails, especially that snails have more than 26,000 teeth, and asked us to observe the teeth of snails in a container with a magnifying glass on it. Through a magnifying glass, we saw many thin, sharp teeth like needles in the snail's open mouth. It was incredible. I thought it must be a gourmet, otherwise what would be the point of having so many teeth.

3. Introduction to the pink snail?

The red snail is a plump snail weighing about 20 grams. It is inedible and lives in the swamps of the scrub forests of North America.

In the swamps of North America, there live brightly colored red-shelled snails. They are plump and weigh about 20 grams. They are inedible. They like to hide during the day and come out at night. They love to eat chlorophyll on broad leaves. Their tongue is soft and long, with mucus, but it is actually very powerful. There are many teeth buried in the mucus of the long tongue that looks fresh and tender. There are 135 teeth in a vertical row and 105 teeth in a horizontal row, for a total of 14,175 teeth. Under a microscope, it looks like a nail board covered with spikes. When the tongue gently licks the green leaves, all the chlorophyll is eaten into the stomach.

4. How to describe the snail’s teeth?

1. All the teeth of snails grow on their tongues and are divided into several rows. According to calculations, they have more than 26,000 teeth in total. Although snails have many teeth, they are not used for chewing. They can only use their tongues to crush food for easy digestion.

A snail's teeth are very sharp, but they will slowly wear out and become blunt, and will be replaced by new, sharper teeth.

2. The snail's teeth are not like humans' "three-dimensional teeth" arranged up and down to chew food. Instead, they grow on the surface of the tongue and are called "radora tongue".

5. How scary would a snail be if it were magnified 100 times?

It's not very scary. It just has 260,000 teeth. It turns out that it relies on a large number of teeth to form a belt-like tooth house to chew food for better digestion.

There is a wide and thin horizontal fold on the snail's abdomen, with a sharper back end. This is its "foot". When a snail crawls, it uses its foot to cling to other objects. It moves forward by relying on the ups and downs of its foot with well-developed abdominal muscles.
