Sulfur Hydrothermal Vent Deep Ocean Biome & Scaly-foot Snail

It is suggested to add the Scaly-foot Snail (Chrysomallon squamiferum)—an endangered deep-sea living fossil with a 500-million-year history—to Minecraft's Sulfur-Themed Update, integrating real-world science and wildlife conservation. This creative concept is put forward by a Chinese Minecraft player.
