What are the living habits of abalone?

1. Abalone likes to hide during the day and come out at night. Abalone kept in a pond usually stays dormant during the day and slowly moves as soon as it gets dark. They are most active from 10 am to 3 am. At that time, their heads and feet are fully extended, and the tentacles on the cracks of the mantle extend from the holes in the shell, crawling on the bottom or wall of the pond. They can crawl up to 50 cm per minute.

2. Abalone also has the habit of returning to their nests. They often like to live in caves, go out to hunt for food at night, and return to the caves to live when it is almost dawn.

3. Abalone likes to eat brown algae or red algae. For example, the large abalone likes to eat wakame, young kelp and Sargassum. Abalone raised in a pond can eat dozens of grams of small kelp every day. The amount of food abalone eats varies with the season. Generally, they eat more in the season with higher water temperature, and they are less active and eat less in winter.

4. Abalone likes to eat brown algae or red algae. For example, the big abalone likes to eat wakame, young kelp and Sargassum. The amount of food abalone eats varies with the season. Generally, it eats more in the season with higher water temperature; it is not very active in winter and eats less. There are many types of abalone and they are widely distributed. Abalone is distributed along the coast of my country.

5. In the north, Dalian and Changshan Island produce more abalones, which are large and ovoid. In the South China Sea, there are abalones and abalones. Abalones and abalones are similar in shape, but smaller. Abalones are larger in size, and their shells are more like ears. The meat on their feet is the thickest, and the shells cannot completely cover them.

The head of the abalone is well developed, and its two tentacles are very thin and long when stretched. There is a short protrusion on the back of the base of each tentacles, and the eyes grow at the end of the protrusion. There is a head lobe between the two tentacles, and there is a proboscis on the ventral side of the head lobe, with a sun at the front end of the proboscis. There is a powerful radula inside the mouth, which is a unique organ of many shellfish. It is a chitinous belt with many rows of small teeth on it, and its shape is very similar to a file. Shellfish use these small teeth to scrape and grind food.

Generally speaking, herbivorous species have more denticles with round tips, while carnivorous species have fewer but powerful denticles with hooks or spines at the tips. Abalone is a herbivorous species, so its radula has a large number of denticles.

The outside of the abalone's body is covered with a thick calcareous shell, which is a right-handed spiral shell and shaped like an ear. Its Latin name can be literally translated as sea ear because its shell is shaped like an ear.

What are the living habits of abalone?

Abalone is a very valuable seafood. It is not a fish, but a single-shell mollusk that crawls on rocks below the low tide line in shallow seas.

The abalone's body is covered with a thick calcareous shell. Its shell is a right-handed spiral shell that looks like an ear. Its Latin name can be literally translated as "sea ear" because its shell looks like an ear. In addition, the abalone shell has a series of spiral protrusions that gradually increase from the top of the shell to the ventral side. Some of these protrusions near the end of the whorl are penetrated into holes, and the number of holes varies with different species. The large abalone distributed in northern my country has 4-5 holes, and the variegated abalone distributed in the south has 7-9 holes. In ancient my country, abalone was named "nine-hole snail" because of this feature.

The head of the abalone is well-developed, and its two tentacles are very thin and long when stretched out. There is a short protrusion on the dorsal side of the base of the tentacles, and the eyes grow at the end of the protrusions. There is a head lobe between the two tentacles, and there is a proboscis on the ventral side of the head lobe, and there is a sun at the front end of the proboscis. There is a powerful radula inside the mouth. The radula is a unique organ of many shellfish. It is a chitinous belt with many rows of small teeth on it. The shape is very similar to a file. Shellfish use these small teeth to scrape and grind food. Generally speaking, herbivorous species have more small teeth with round tips, while carnivorous species have fewer small teeth, but they are powerful, and often have hooks or thorns at the tip. Abalone is a herbivorous species, so the number of small teeth on its radula belt is extremely large.

The abalone's foot is particularly thick and is divided into two parts. The upper foot has many tentacles and hillocks to sense the outside world; the lower foot is oval when stretched, with a flat belly, suitable for attachment and crawling. We eat abalone mainly for its foot muscles.

The mantle of abalone is the same shape as the shell, covering the back of the body. Unlike other snails, there is a crack on the right side of the mantle of abalone. The position of this crack is equivalent to the position of the hole on the edge of the shell. Tentacles grow on the edge of the crack. When the abalone moves, these tentacles extend from the shell hole to play a role. The crack on the edge of the mantle is a characteristic of primitive gastropods, such as the seam snail, the famous red scallop and the keyhole snail.

Abalones live in rocky reefs with fast-flowing water and lush seaweed. They like to live in coastal islands or rocky corners protruding from the coast. Abalones often crawl in cracks or caves in rocky reefs. The depth of their distribution varies with species. For example, the large abalone in northern my country is generally distributed in water depths of more than ten meters. In winter, they move to deeper waters to avoid the cold, and the depth can reach 30 meters. In spring, they slowly move up, and some can live several meters below the tide line. Small abalone can even be found near the low tide line.

Abalone likes to hide during the day and come out at night. Abalone kept in a pond usually stays dormant during the day and slowly moves as soon as it gets dark. They are most active after 10 o'clock and before 3 o'clock in the evening. At that time, their heads and feet are fully stretched, and the tentacles on the cracks of the mantle extend from the shell holes and crawl on the bottom or wall of the pond. They can crawl up to 50 centimeters per minute. Abalone also has the habit of returning to their nests. They often like to live in caves, go out to forage at night, and return to the caves to live when it is almost dawn.

In the deep sea, the temperature is low (4 degrees Celsius) and the sunlight cannot reach, so there are few nutrients, so abalone grows very slowly in this hidden environment, which is why those big abalone are so expensive while small abalone are very cheap.

Abalone is a very precious seafood. It is not a fish.

It likes water.
