Living habits
Looking for food
Crabs spend most of their time looking for food. Generally speaking, they are not picky about food, and they can eat all the food they can. Small fish and shrimp are their favorites, but some crabs eat seaweed and even animal carcasses or plants.
compete
Crabs eat other animals, and other animals may eat crabs. For example, humans regard crabs as delicacies, and waterfowl also eat crabs. Some fish like to eat crab feet just like humans. When young and underage crabs float in the sea, they may be devoured by other marine life, so crabs must lay a lot of eggs when laying eggs.
type
They rely on the mother crab to give birth to small crabs, and every time the mother crab will lay a large number of eggs, the number can reach more than one million. After these eggs hatch in the belly of the mother crab, the young crab can leave the mother and float around with the coastal water. After molting several times, it grows into a big-eyed larva, and after molting several times, it grows into a young crab. The appearance of young crabs is almost the same as that of adult crabs, and they become crabs after molting several times. Most sea crabs are directly discharged into the sea without hatching after their eggs mature.
