The Safe Shallows is the first biome encountered by the player, as it is where Lifepod 5 crashed. This is also the starting point of the game, mainly located near the center of the map. The biome has multiple sections that are not directly connected to each other, but all these fragments of the biome have the same general look.
The Safe Shallows contains coral reefs sprawling over a large part of the area, with small cave systems that can be found beneath the surface. As the name implies, this biome is one of the safest in the game, as it is a relatively shallow area, there are few environmental hazards, and no predators call this biome home. However, caution should still be used for the occasional Gasopods passing through, and the caves are frequently home to hostile Crashfish. Some predators are also known to wander here from adjacent biomes, mainly Stalkers from the Kelp Forests, and Sand Sharks from the Grassy Plateaus.
The Safe Shallows offers plentiful diving experiences for all players, especially newcomers, as it is home to a variety of life forms; coral, fauna (mostly edible), and flora alike, with a great abundance of harvestable materials. It is one of the most colorful biomes in the game.
