CATDOLL : CATDOLL: Crabs can be kept in water for a few days

Crabs can be kept in water for 5 to 10 days.

Crabs can live in water for 5 to 10 days. You can put the crabs in a tall plastic bucket with smooth inner walls. Be careful not to stack them. Just add water to half the height of the crab. Do not bury the crab completely. The crab will be unable to breathe if the water is too deep.

Using this method to preserve crabs, if the temperature is not too high, they can generally be preserved for 5 days. Under reasonable preservation conditions, crabs can survive for about 10 days by adding some water to maintain humidity. Crabs are picky about their living environment and cannot be too dry or too wet.

Crab's living habits

1. Foraging

Crabs spend most of their time looking for food. They are generally not picky eaters and will eat anything they can get their claws on. Small fish and shrimp are their favorites, but some crabs eat seaweed and even dead animals and plants.

2. Competition

Crabs eat other animals, and other animals may also eat crabs. For example, humans regard crabs as delicacies, and water birds also eat crabs. Some fish also like to eat crab legs like humans. When young crabs float in the sea in groups, they may be preyed upon by other marine life. Therefore, crabs lay a lot of eggs when spawning to ensure the survival rate of crabs.

3. Reproduction

They rely on the mother crab to give birth to the crabs. Each time the mother crab will lay a lot of eggs, the number can reach millions or more. After these eggs hatch in the abdomen of the mother crab, the larvae can separate from the mother and float around with the coastal tide. After several molting, they grow into big-eyed larvae, which molt several more times to grow into young crabs. The appearance of the young crabs is almost the same as that of adult crabs. After several more molting, they become crabs.
