1. What are the similarities and differences between “snail” and “earthworm”?

same:

1. The body is sticky.

2. The crawling speed is not very fast. They like to live in dark and humid places.

different:

1. Snails have shells but earthworms do not, so snails are pests.

2. Earthworms can burrow underground and are good friends of crops. The difference between them in exploring the world is that snails use tentacles, while earthworms use the bristles on their bodies.

snails

1. The body structure of a snail: The body of a snail is soft, with a shell on its back. The shell grows with the snail as it grows. There are two pairs of tentacles on the head of the snail, with eyes on the top of the long tentacles. The foot used by the snail to crawl is called the ventral foot. The snail can use the ventral foot to crawl on various objects such as glass and cotton thread in a wave-like manner, leaving mucus.

2. Snails can respond to external stimuli, such as extending and retracting their tentacles and retracting their bodies into their shells to avoid danger. We can wake up sleeping snails by putting them in water.

3. The habit of snails: They are suitable for living in cool and moist grass. Snails mainly eat fresh vegetables, and also eat bread and other foods.

earthworm

1. The body structure of earthworms: The body consists of three parts: the mouth, the annulus, and the anus. The annulus is at the end closer to the mouth. The mouth is responsible for eating, the anus is responsible for excretion, and the annulus is responsible for reproduction.

2. Earthworms can respond to external stimuli. They can stretch and retract when crawling, and will shrink their bodies when encountering danger. They are not suitable for living in water and will drill out of the soil after a heavy rain.

3. Habits of earthworms: Earthworms are suitable for living in moist, dark, loose soil. The food of earthworms is mainly rotten fallen leaves.

They are two different species, but both are hermaphrodites. Both can be used as Chinese medicine. The movement and excrement of earthworms are very beneficial to improving the quality of soil, which can keep the soil permeable and healthy, and play an important role in agriculture. Generally, snails feed on plant leaves and tender shoots, so they are an agricultural pest.
