In the case of a crab in general, there is nothing particularly liked, he just walks sideways, but he should like a bright ground crab in general, there is nothing particularly liked, he just walks sideways, but he should like a bright place. The crab should be playing with seaweed on one side.

Of course, this crab likes to play on the beach. Well, the sand on the beach, pebbles are the best toys for crabs. So they should prefer to play in the sand.

To give them egg skin or egg yolk, I raise it to eat, rice can also be tried, the important thing is to put mud and sand, change the water frequently.

Marine crabs eat fish, and freshwater crabs eat rainbow worms and fish. Brother.

Crabs are omnivorous. The foods they can eat are:

1. If conditions permit, feed live nematodes, or attack the core to feed egg yolks. Pay attention to the amount of feeding, eat within half an hour, if you can't eat, the water will become dirty;

2. You can also feed them fish, sea crabs can feed the internal organs of chickens and ducks, or small fish and shrimp, whether raw fish or dried fish, they can accept it;

3. They may also be fed fish feed, bloodworms, dried shrimps, snails, and mussels;

4. It is best to feed some grass foods frequently, such as bitter grass and elosa.

The vast majority of species of crabs live in the sea or near the sea, but some inhabit freshwater or land. Common crabs include pike crab, open sea pike crab, blue crab and Chinese mitten crab (river crab, hairy crab, clear water crab) and so on.

A small group of crabs breed entirely in freshwater, and they mostly inhabit the rocks of mountain streams. There are also a few crabs, such as ground crabs, that can adapt to life on land, burrowing in damp mud holes, and migrating to the sea during the breeding season. The vast majority of crabs are omnivorous.

Some crabs are carnivorous, such as pike crabs, which can prey on fish, shrimp and molluscs. A small number of crabs, such as the crab, scrape or filter feed on algae and organic debris.

The crab's habits and reproduction are very interesting.

After several shells, they grow into big-eyed larvae, and the big-eyed larvae grow into juvenile crabs after several shells, and the appearance of juvenile crabs is almost the same as that of adult crabs, and then after several shells, they become crabs. Most marine crabs are released into the ocean without hatching after their eggs have matured. The hard carapace of the crab protects the crab from predators, but the carapace does not expand as the body grows.

Therefore, the growth of crabs is interstitial, that is, after a period of time, the body will continue to grow after the old shell is shed. The largest crabs on the planet are spider crabs, with their feet spread out and wide to a meter, and the smallest crabs are bean crabs, which are less than half a centimeter in diameter.

Although the crab is small, it has all kinds of organs. When the hard shell of the crab is removed, we can find that the crab's body parts are protected by a layer of shells, shield-like shells that biologists call carapace. The pair of appendages in front of them have strong chelae that can be used for foraging, and the other four pairs of appendages are the feet of the crabs, and the crabs rely on these four pairs of appendages to walk and move, and they walk in a unique and interesting way, mostly walking sideways rather than straight forward.

The exception is monk crabs, which walk straight. Crabs spend most of their time looking for food, they are not picky eaters, and they can eat as much food as they can get their hands on. Small fish and shrimp are their favorite, and some crabs also eat seaweed, even animal carcasses or plants.

Crabs eat other animals, and other animals may also eat crabs, for example, humans use crabs as a delicacy. There are also water birds that eat crabs! Some fish also like humans to eat crab legs.

When young and juvenile crabs float in the sea in groups, they may be eaten by other marine organisms, which is why crabs lay a lot of eggs when they lay eggs.

Fiddler crabs are common crabs on the seashore, and the giant claws of male fiddler crabs resemble playing a violin, so they are also called fiddler crabs or fiddler crabs.

Sideways! If you eat meat, you still eat the meat of male crabs is sweeter, the gill cover at the bottom of male crabs is triangular, and the bottom gill cover of female crabs is more oval.

It's fun for two crabs to clamp themselves with their own pincers!

The other party is also super ruthless· Legs and feet, look at this point and feel it!

It's fun to use crab clips or fish or other live things, too· Played in the kitchen before! Put some alcohol on the back! He runs fast at all!

It might be a little cruel! ~
