Flower crabs grow in a special environment and need to find food in the deep sea, so the production of flower crabs is less and the price is relatively higher. Green crab is a common type of crab, the production is larger than flower crab, so the price is relatively cheaper. In the market, the price of a medium-sized flower crab is usually more than 100 yuan, while the price of a medium-sized green crab is usually about 50 yuan.
