Extended data

Living habits: Ampullaria gigas likes to live in fresh water with fresh water quality and sufficient bait. Many groups inhabit the shallow water near the pool, or adsorb on the stems and leaves of aquatic plants, or float on the water surface, and can live out of water for a short time.

The optimum water temperature for growth is 25 ~ 32℃. When the temperature exceeds 35℃, the growth rate will obviously decrease. The highest critical water temperature for survival is 45℃, and the lowest critical water temperature is 5℃. Pomacea canaliculata is an omnivorous snail which mainly feeds on plant food, mainly duckweed, vegetables and fruits.
