乐生活Friend @ the two blue ribbon of the butterfly is given to my first three Traumatophora triscalpta (Martens, 1875). It’s interesting to see that the neck of the snail has obvious contraction, three teeth in the mouth correspond to three striations on the outside. This structure is apparently for predators like giant carapace or fluorescence. The soft flesh of snails can enter and exit freely, while insects can hardly drill in from the screw to harm them. Tridentata is a large ornamental snail commonly found in Tianmu Mountains, and is placed in the subfamily Basnail (Wu, 2019) because of the discovery of a vectorial structure.
