How many varieties of snails are there? 20

Mud snails, generally inhabit lakes, ditches, ponds and rice fields, this kind of snail we eat to raise for a few days, after raising the snail meat is delicious, the nutritional value is OK.

2.Stone snails, like to adsorb on stones, generally grow in relatively clear and clean streams and rivers, its activity is the habit of day and night, hiding under the stones during the day, coming out to feed at night, stone snails are nutritious food, the meat is crisp and sweet.

3.The appearance of the snail is similar to that of the mud snail, and the head and gastropods are protruding when crawling in the water, and the head has 2 pairs of antennae, and it likes to live in rice fields and ponds. It is an omnivorous snail based on plant-based bait, which we generally do not eat (take it home to feed chickens and ducks).

There are a lot of mud snails in the pond of my uncle's house, we picked up 5-6 catties in about 1 hour, this kind of snails can not be remembered to eat at home, must be raised with water for two or three days, during which the water must be constantly changed to wait for the snails to spit out the mud in the body before they can be burned and eaten, before burning, the tail of the snail should be reduced with pliers to facilitate the rapid meat.

Heat the fire, add oil to the pot, add bean drums, garlic and other ingredients to stir-fry the flavor of snails and garlic and ginger, add the soup after the herb seeds are seasoned and simmer for 10 minutes. [Like].

There are two kinds, one is naturally born and the other is artificially farmed.

Nautilus, loquat snail, weave snail, phoenix snail, dragon palace Weng Rong snail, etc.

1. Nautilus: marine mollusk, only found in the Indian Ocean and the Pacific Ocean, north to the south of Japan, south to the Great Barrier Reef, west to the Andaman Sea, east to Fiji and other regions. Located in French New Caledonia, the main production area of nautilus, the nautilus is also used as the main pattern of the national emblem.

Nautilus has undergone hundreds of millions of years of evolution on the earth, but its appearance and habits have changed very little, and it is called a "living fossil" in the ocean, which has high value in studying biological evolution and paleontology.

2. Loquat snail: Loquat snail is a kind of loquat snail in the family Loquat snail of the order Heteropodae. It is mainly distributed in Malaysia, Indonesia, Chinese mainland and Taiwan, and often inhabits the subtidal zone.

3. Weaving snail: commonly known as sea snail, sea lion snail, wheat snail or white snail, and in some places it is also called cut incense snail, small yellow snail, and nail cone snail. It belongs to the phylum Mollusk, Gastropoda, and Snails.

The appearance characteristics of the snail are that the tail is sharp, slender, about 1 cm in length and about cm in width, and is abundant in the coastal areas of Guangdong, Zhejiang and Fujian. Its appearance is characterized by a pointed tail and a slender snail, with a length of about 1 cm and a width of about cm.

4. Phoenix snail: It is widely distributed and has traces in the Indo-Pacific waters south of Amami Island in Japan, north of Australia, and east of East Africa. Hainan, Xisha Islands, South Korea, Indonesia, Malaysia, Singapore, Taiwan.

5. Longgong Weng Rong snail: commonly known as snakeskin snail. Family and genus classification: shellfish, molluscs, gastropods, primitive gastropods, and snails.

The snail can be said to be a large group, with more than 40,000 species, and belongs to the mollusks among the invertebrates. The more common varieties are as follows:

1. Salamander: also called spiral snail. Usually lives in crevices in rocky reefs. Shaped like a spinning top, the shells are thick.

Because of its wide living area, the temperature requirements are not strict. Ideal for keeping in aquariums with lots of live rocks, no special feeding is required. It will also help clean the algae on the tank wall, which can effectively control the algae in the aquarium.

2. Horseshoe snail:

Horseshoe snails are also called felt cap snails and pearl snails. The shells are smooth and spiral-shaped. There are some unsolved taxonomic problems with this snail, and most pearl snails live in colder water.

It is very popular in breeding and is a good helper for controlling algae. Suitable for keeping in aquariums with live stones. Safe for corals.

Intolerant of copper-containing drugs and high nitrates. Difficult to reproduce in an aquarium.

3. Crab snail:

4. Star snail: also called Astraya star snail or Astraya snail. The shell is tapered; Some have radial threads. If there is enough hiding place and space, the star snail will be very suitable for keeping in an aquarium.

It would be better if it could provide living stones for it to eat the algae, which will also eat the algae on the walls of the tank. In particular, it will eat cyanobacteria and diatoms. If you fall off your back, you often can't turn over on your own and need the help of your keeper.

It is sensitive to copper-containing drugs and cannot tolerate high nitrate environments. You can add some vegetables such as spinach and lettuce.

5. Wheat snail: 6. Bell snail:

The shape of the bell snail family is cone-shaped, pyramidal-shaped. The shells are grayish-white with maroon veins and are usually covered with algae. There are some varieties that have not used the extra one foot, black, white or brown. If you provide enough space and food, you will be able to adapt to aquarium life.

Morphological characteristics of snails:

The snail shell is conical, thick, the shell is about 3 cm high, the top of the shell, the spiral layer is 7 layers, the suture line is deep, and the body snail layer is slightly larger; The shell surface is yellowish-brown or dark brown, with obvious growth streaks and thick spiral ridges. The mouth of the shell is oval with an intact margin. It is, yellowish-brown, oval, smooth, with growth lines arranged in concentric rings.

The body is soft, the head is cylindrical, and the front end has a prominent muzzle; There is a pair of antennae at the base of the mouth, and there is a raised eye on the outside of the base of each antennae. The foot is located below the head and is large in shape with a broad plantar surface. The head and feet can be retracted into the shell, and when retracted, the snail shell is closed.

1.The appearance is different:

The size of the snail is generally relatively large, the small one is about the same as a quail egg, and the large one is like a ping pong ball. Its shell is relatively thin, with a smooth surface and a pale dark green color. The snail is generally smaller, about the size of a finger.

Its shell is thick and hard, with a textured surface and a deep dark green color.

2.Growing in different environments:

Stone snails grow in rivers and ponds, and are mostly attached to hard objects such as stones in the water, while field snails grow in rice fields, ponds, and rivers.

3.The taste is different:

Because of the large size of the snail, the meat is also large and tastes better, while the stone snail is small and the meat is smaller, and it tastes more chewy, but both snails are rich in nutritional value.

First of all, the snail is relatively large and grows fast, while the snail grows slowly and is much smaller. Generally, the snail will be the size of a baby egg, the big one will be the size of a duck egg, and the stone snail will be much smaller, generally not as big as our thumb.

From the point of view of living place, most of the snails live in rice fields, drainage ditches and ponds, while most of the stone snails live in the ditches of the outer rivers. That is to say, snails prefer to live in mud fields, while snails prefer places where there are stones and sand.

When snails and snails are the same size, they can only be distinguished by comparing the hardness and softness of their shells. The shell of a stone snail is particularly hard, while the shell of a field snail is much thinner and can be easily broken.

The above points are the most important differences between field snails and stone snails.

Both snails and stone snails can be eaten, like the meat in the snails is larger, and you can stir-fry them with chili peppers after you get them out, or you can braise the whole snail after cleaning the snail.

It's all about its shape, including some of its types, and I think there will be some gaps in its overall category, so there will definitely be a big difference.

The snail is a collective term for shelled gastropods of the class Gastropoda, with more than 40,000 known species worldwide.

The types of snails include salamander snails, horseshoe snails, crab snails, star snails, wheat snails, striped bell snails, Tongan weave snails, etc.

It belongs to invertebrates.

mollusks.

The body is covered with a cone-shaped, spindle-shaped, or oval-shaped hard shell, with swirling shells to protect the soft body, and the body secretes fluids that help it easily attach to smooth surfaces, as well as a harmful mixture to keep predators at bay.

Snails are a common name for the mollusks gastropods, which are an important part of the macroinvertebrates of wetland ecosystems.

The conch belongs to the mollusk gastropod, phylum molluscs. There are more than 70,000 species of shellfish in the world, and the marine species can be commonly known as sea snails.

Like other animals, mollusks such as conch have adapted to a kaleidoscopic environment. From rocks washed by the sea day and night to the dark and muddy depths of the sea, habitats of all forms have their own special mollusks. Tides affect the characteristics and distribution of mollusks that grow near the sea, as do the characteristics of the geological surface on which they live.

However, the food provided by sufficient sunlight is more important. Molluscans are best suited to inhabit the tropics, so the variety of sea shells in this area is breathtaking. Coral is the home of brightly colored snails, treasure snails, and vortex snails; In the mangrove forests, oysters live and live on their roots, stinging snails like to cling to branches and leaves, and crab snails crawl quietly on the mudflats.

Of course, the temperate sea will also be an eye-opener for collectors. The beach is a haven for many bivalves and burrowing gastropods such as the snail. At the mouth of the river, mud and sand are mixed, creating an environment where food is abundant, and large numbers of birdtail clams are often found.

The rocky shore is a great hunting ground for gastropods, which cling firmly to the rocks.

There are more than 100,000 species of gastropod alone.
