According to the Kuaiduo Encyclopedia, we learned that the victory dawn crab (scientific name: Matuta victor), also known as the tenacious dawn crab, latent sand crab, and sand sui, is an animal of the genus Dawn Crab in the family Dawn Crabidae. Its cephalothorax is nearly round, the forehead is slightly wider than the eye sockets, the middle part of the front edge is protruding, and it is divided into two teeth by a "V" shaped notch. The lower inner eye socket teeth are smooth and obtuse, with 3 small blunt teeth on the edge. Victory Dawn Crabs are non-toxic and can be eaten. Its meat is tender, delicious and nutritious. It is a carnivorous animal that often dives into the sand with only its eyes exposed, waiting for opportunities to prey on other small animals nearby, such as short-fingered monk crabs and double-splayed window crabs. It sometimes also eats the carcasses left by stranded fish.

The Victory Dawn Crab is found on sandy beaches and shallow sea bottoms in the Indian and Western Pacific Oceans. In China, it is mainly distributed in the East China Sea and South China Sea. It can also be found in Japan, Korea, Australia, Malaysia, Singapore, Indonesia, Philippines, New Caledonia, Fiji Islands, India, East Africa, and the Red Sea.
