After reading the small experiment, you will understand, why is the sand crab called the sand crab?

Sand crabs mostly live in the intertidal and supratidal zones of the warm sea, and are burrowing animals, generally burrowing in deep holes on the beach.

The cave where sand crabs live is generally spiral-shaped, and a sand tower is formed at the entrance of the hole, which is unique to sand crab caves. Female sand crabs have a sand tower in their burrows, and male crabs may live in their burrows. The muddy mud of the tidal flats is not suitable for digging holes to catch sand crabs, and the burrows of sand crabs often have "opposite holes", you dig once, and the sand crabs will flee to the other side.

According to the characteristics of the sand crab that it is clamped, the fisherman uses a rope to stuff it into the hole and slowly pull it out to trap it, which is commonly known as "pulling the sand crab". Sand crabs are very agile and not easy to catch, often crawling with the second and third pairs of feet, with a speed of up to 1 meter per second, and the sand crab will only use the fourth pair of feet when it stops or changes direction. Sand crabs have long eye stalks, so they can peek out of the cave even if they are in the cave.

Sand crab larvae feed on plankton, and adults like to climb in mangroves, toss branches and leaves, and use claws to catch flies, insects, decaying small animal carcasses (fish, shrimp, sea cucumbers, molluscs, etc.), and also eat algae.

For the sand crab catching, after finding the sand crab hole, first judge the size of the sand crab and the difficulty of catching the sand crab. There is a very simple way to judge, the sand crab with a large hole is large, and the sand crab with a small hole is small. There is a lot of sand crab sand shaved out by the entrance of the cave, and those caves that do not see a little movement are deep holes, which are difficult to catch, and shallow caves are easy, and you will be caught by digging along the sand crab holes.

If you're lucky, you'll see sand crabs struggling to dig holes. The holes of large sand crabs are often very deep, even more than 1 meter deep, and they are not in a straight line. You can use the method of filling dry sand:

It is to take some dry sand and carefully pour it into the sand crab hole, pour it near the mouth of the hole, and then excavate.

Sand crabs can not be farmed in fresh water, and can be stored in fresh water in the short term, because of the different living habits and environment, marine crabs cannot survive in fresh water for a long time.

Sand crabs mostly live in the intertidal zone and the supratidal zone of the warm sea, and generally burrow in deep holes on the beach, and sand towers will be formed at the entrance of the hole, which is unique to sand crab caves.

You don't need to look at the small experiment to understand that the sand crab is called the sand crab because it was originally named that.

Sand crabs, why do they eat sand.

Sand crabs eat sand and spit out sand balls! It's called sand crab balls, and this one doesn't have a lot of attention. Because sand crabs are the dominant crabs living in the intertidal zone and the supratidal zone of the warm sea, the cave dwells in the deep hole of the beach, the hole is generally spiral-shaped, and the hole mouth forms a sand tower, which is unique to sand crabs.

The hole of the female crab is as high as a sand tower and may contain a male crab. The sand crab is extremely agile, often crawling with two pairs of feet and a speed of up to 1 meter per second, and only uses four pairs of feet when stopping or changing direction. The sand crab has a long eye stalk, and it can also peek out of the hole while in the hole.

The larvae feed on plankton, and the adults like to climb in the mangroves, toss the branches and leaves, catch flies, Kunchun larvae, rotting small animal carcasses (fish, shrimp, sea cucumbers, molluscs, etc.) with chelicerae clamps, and also eat algae. Fiddler crabs swallow sediment, and females can clamp the sediment into their mouths and discard the inedible parts. The male has only one feeding chela, and the other chela is very specialized, and its weight can reach 1 2 of the overall weight, which is called the mating chela, and can make various show-off actions before mating.

Female crabs follow the swimming male crabs into the cave to mate. At night, the male crab taps the ground rhythmically with a large claw to attract the female. Fiddler crabs are one of the most interesting groups of crabs because they have social swarming behaviors, and their vision can be used as a signal for crabs to communicate, communicate, and warn each other.

Sand crab sauce is a delicacy that Beihai people can't do without all year round, and it can be said that almost every local household has this flavored sauce. The taste of sand crab is extremely fresh, so the method is very simple, and too complicated process will destroy the original freshness of sand crab.

Step 1: Choose live sand crabs, don't die them.

Step 2: Place the sand crab in a bucket with clean seawater, let the sand crab swim in it and wash it gently by hand, changing the water several times. The purpose is to clean the sand crabs. (I'm in silver.)

The beach is washed directly in the seawater and brought back, and it can be sorted out directly.

Many people's practice is to use tap water to clean it when they get home, I have done it before, and I found that the tap water will wash away the original taste of the sand crab, and the flavor of the sand crab juice made is far behind).

Step 3: Remove the umbilical cover from the bottom of the belly of the sand crab, or squeeze out the dirt from the bottom of the umbilicus.

Step 4: Put the sand crab into a clean and dry clay tray (similar to a tamper), add two taels of salt per kilogram of sand crab, and mash the sand crab with a clean wooden stick. (I use a glass jar, remember not to use a plastic jar, the sand crab juice made from the plastic jar has a peculiar smell and affects the taste).

Step 5: After mashing, put in an appropriate amount of chopped garlic, an appropriate amount of ginger, (you can add an appropriate amount of chili pepper), an appropriate amount of white wine, and mix well. (Adding too many trimmings will affect the original flavor of the sand crab juice, so I only add cold boiled water.)

I heard that the sand crab juice made with pure white wine is more delicious, so I'll leave this for the next experiment).

Step 6: Divide it into glass bottles (this step can also be done with a glass lid on a clay disk) and leave it in the sun to dry for about an hour (if the amount is large, the drying time will also increase). The result is the traditional North Sea sand crab sauce!

Finally, a few pictures of the finished product and tempting specialties!

Braised beans in sand crab sauce is a special dish in Beihai, which uses the unique taste of sand crab juice. It is made in a simple way, drizzling sand crab juice when the beans are almost ripe, and then simmering for a while, and it can be freshly baked. Someone once described this dish as follows:

The green beans are sandwiched with some thin crab shells, crab legs and the like, and the juice is light gray. In addition to the sweetness of the beans, there is also a very special taste, a little fishy, but very fresh, and it is addictive. "The taste of the beans is mixed with the aroma of crab, the taste is salty, and sometimes when you eat the beans, you will chew out the sound of crab legs. ”
