1, production and growth cycle: the production of Australian dragon is relatively small, and its growth cycle is longer. This means that the cost of breeding Australian dragons is relatively high, resulting in higher prices. In contrast, Brontosaurus has a larger production and a shorter growth cycle, so the price is relatively low.

2. Price: Because of the large production of Porcupine, the price is relatively affordable; while the production of Auslese Dragon is small and has seasonal restrictions, so the price is relatively expensive. In the market, the price of Australian dragon is more than 200 yuan per catty. In contrast, the price of Boron is relatively more affordable, the price is between 100 yuan and 150 yuan per catty.
