Pinctada longifolia has a breeding base in the East China Sea, the South China Sea and the Taiwan Strait, Japan, the Philippines and other places, generally distributed within 30 cm of shallow sea warm water, mostly inhabiting the sediment or sand seabed.
It has a pale brownish yellow body, 7 to 8 teeth on the upper edge of the frontal horn, 4 to 6 teeth on the lower edge, and the lateral view of the base of the frontal horn is higher than that of Chinese shrimp and lower than that of Penaeus Meggi. The posterior frontal ridge extends near the posterior edge of the cephalothorax without a central groove. The first antennal whip is slightly longer than the cephalothorax, and the third jaw of the male shrimp has long brush-like hairs. There are intermittent notches on the frontal ridge, and the warts at the top of the anterior fragment of the female mater are smaller than those of Murgey shrimp.
P. longifolia is an annual shrimp, but there are also individuals with a life cycle of up to two years, in which it has to go through several different stages of development, each different stage of development, the requirements for external environmental conditions are not the same, that is, individuals at different stages of development, showing different ecological types.
Around the time of the Qingming Dynasty every year, P. pertusus perennially rises with the water temperature, and travels from the overwintering sea area to the inland bay and estuary as bait and spawn.
