In fact, the real name of the love crab should be "tide crab". Whenever the tide rises, it will hide in the hole and hold up its strong and powerful crab at the entrance of the hole. Its large claws seem to be waving to welcome the arrival of the tide, hence the name "fiddler crab". Its body color also changes throughout the day and night. It is dark during the day and turns light gray at night. Love crabs are easy to raise, just feed them some vegetables, watermelon rinds, etc. every day.

Fiddler crab

A genus of the family Sand Crabs in the order Decapoda. The cephalothorax is trapezoidal. The front is wide and the back is narrow, the forehead is narrow, the eye sockets are wide, and the eye stalks are slender. The size of the two male claws is very different. The large claws (called mating claws) are extremely large, even larger than the body, weighing almost half of the whole body. The small claws are extremely small and are used for feeding (called feeding claws). The two female claws are small and symmetrical, with spoon-shaped knuckles. They are both feeding claws. Widely distributed in intertidal zones of tropical and subtropical regions around the world, it is a warm-water, gregarious crab. There are about 10 species in the genus Chinese Fiddler Crab. Common species include arc-edge fiddler crab, concave-fingered fiddler crab, white fiddler crab, ring-banded fiddler crab, etc., which are distributed in coastal provinces, Hainan, Taiwan and other provinces.

Fiddler crabs live in caves and often have dedicated caves, but they often change them every few days. The depth of digging a hole is related to the water table. Generally, the bottom of the hole needs to reach moist soil. Many male crabs also build a semicircular umbrella-shaped cover to cover the entrance of the cave. The activities of fiddler crabs follow a certain pattern with the rise and fall of the tide. During high tide, they stop at the bottom of caves. After low tide, they move to the beach to feed, repair caves, and finally occupy the caves in preparation for mating. They rely on vision and hearing to receive communication, contact, and warning signals. Achieve social gathering behavior. Fiddler crabs feed on sediment, swallowing the sediment, ingesting organic matter, and spitting out the inedible parts. Before mating, males can wave their large pincers to perform various showoffs to attract females. When moving in the intertidal zone, they seem to be summoning the tide, hence the name. The female then follows the male into the cave to mate. At night, males often tap their large claws rhythmically on the ground to attract females.
