The Sea Snail is a rare enemy that spawns in the Ocean on either end of the world, usually during the night. Even then the spawn rate is still the lowest of all enemies in the Ocean, one third that of Squids. It slowly crawls along the sea floor.
- 它非常像 Syrinx aruanus（澳洲圣螺）（俗称 Australian trumpet（澳大利亚香螺）或 false trumpet），这是世界上现存最大的蜗牛（带壳腹足动物）物种，也是世界上最大（最重）的腹足动物。
- The Murex sea snail was used to create purple dye, it was so rare that its value was its own weight in gold. This is also why no country has purple in any of their flags.
- 海蜗牛的 怪物图鉴条目：“This unusually large snail makes its home deep in the ocean. Its mucous can be manufactured into a purple dye.”
