Subnautica 2 splits its map into named biomes, each with its own ecology, depth band, and creature mix. Coral Gardens is the shallow heartland where most fish live; Overgrown Ruins is the mid-depth Axum-ruin biome with the Hoverthorn and Pneuma populations; the Sparse Plains, Deep Start, and Collector Leviathan Arena cover the deeper corridors. Each page below lists the creatures and deposits actually placed in that biome, sorted by how often you'll meet them.
