1. #1Safe fauna

   Keys: Fauna, Fish, Animals, Creatures, Aliens, Alien, Animal, Creature

   Bladderfish (used for water), Boomarang, Crismon Ray, Cuddle Fish, Eyeye, Garyfish, Gasopod, Ghost Ray, Hole Fish, Hoop Fish, Hover Fish, Spine Fish, Spade Fish, Reginald, Red Eyeye, Rabbit Ray, Peeper, Oculus, Magmarang. These are all passive fauna and are mostly used for food, supplies and crafting because they are safe and are (mostly) not dangerous.

2. #2Hostile fauna

   Keys: Fauna, Animal, Creature, Alien, Aliens, Creatures, Animals, Fish

   Ampeel, Biter, Blighter, Bone-Shark, Crabsnake, Crab-Squid, Crashfish, Lava Lizard, Mesmer, River Prowler, Sandshark, Warper, Stalker. All of these Fauna in 4546B's oceans are aggressive and dangerous, and it is best to stay away from them unless you have advanced protection.

3. #3Safe Shallows

   Keys: Safe Shallows, Shallows, Shallow, Coral Reef

   Maximum depth 80 meters. Temperature averages 32℃. The Safe Shallows is where {{user}}'s escape pod crashed. The Safe Shallows contains coral reefs sprawling over the entirety of the biome's seabed, as well as small cave systems that can be found beneath the surface. As its name implies, this biome is one of the safest in the Crater, 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 near Gasopods, and the caves are 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 is home to a variety of life forms; coral, fauna, and flora alike, with a great abundance of harvestable materials and edible creatures. It is one of the most colorful biomes in the game.

4. #4Kelp Forestselective

   Keys: Zone, Area, Biome · Secondary: Kelp forest, Forest, Kelp, Creepvine

   Maximum depth 170 meters. Temperature fluctuates from 15°C to 28°C. The Kelp Forests are one of the most productive and dynamic ecosystems on planet 4546B. Kelp Forests are home to mostly passive life forms, with the only exceptions being Stalkers and Drooping Stingers. The seabeds are mostly mossy and sandy, with the terrain being comprised of grassy knolls and arches, which sometimes show entrances to small cave systems. There are also many canyons to be found in these forests. There are a lot of decorative flora on the sandy, grassy bottoms. Most of the raw materials found here are at medium-level depths, with many harvesting nodes such as Limestone and Sandstone. Creepvine seed clusters, found on some Creepvines, provide light and are also crucial ingredients for making lubricant and silicone rubber. There are five Kelp Forests to be found, some containing wrecks, a destroyed lifepod, or both. Large amounts of metal salvage can be found here due to Stalkers' gathering behavior.

5. #5Bulb Zone

   Keys: Zone, Area, Biome · Secondary: Bulb, Koosh

   Maximum depth 480 meters. Temperature averages 13℃. The Bulb Zone is characterized by small crevices and overhangs in a vast, sandy, dune-like area. It is also abundant with small brown algae, and a large variety of plants with blueish-purple hues, the most notable of which being the various sized Bulb Bushes. A deep blue hue shrouds the biome which may make hazards difficult to spot. The Bulb Zone is deep and home to certain dangerous fauna. Notable predators, such as Bonesharks and Ampeels, can be found scattered throughout the Bulb Zone. Occasionally, Mesmers can also be found. There is a cave system located below the Bulb Zone, known as the Bulb Zone Caves. These caves are accessible via any of the three entrances located within the biome. One of the caves links to the Mushroom Forest Caves.

6. #6Crag Fieldselective

   Keys: Zone, Area, Biome · Secondary: Crag, Crag Field

   Maximum depth 460 meters. Temperature fluctuates from 12-24℃. The Crag Field is situated between the Grand Reef, Crash Zone, a Kelp Forest, and one of the Grassy Plateaus. To the south of the Crag Field is the Crater Edge, and to the north, the Aurora's engines. This deep biome features large rock spikes and rippling stone hills, bearing resemblance to the older Grand Reef, all of which is formed atop a massive crag dropping down into the Crater Edge. The Crag Field is a resource-rich biome home to a few low-level predators. Groups of Bonesharks are frequent in the area, and Tiger Plants can also be found in this biome. The biome also features a great abundance of minerals, both in node and deposit form, as well as other resources. Occassionally, a pod of Reefback Leviathans will pass over the Crag Field near the water's surface.

7. #7Blood Kelp Zoneselective

   Keys: Zone, Area, Biome · Secondary: Blood kelp, Blood, Trench, Kelp Trench, Blood Trench, Blood Kelp Trench

   Maximum depth 675 meters. Temperature averages 15℃. The Blood Kelp Trench is located southwest of Lifepod 5, between the Dunes, the Sparse Reef, one of the Grassy Plateaus and the Sea Treader's Path. The Blood Kelp Trench lacks the Crabsquids and Ghost Leviathan in the Northern Blood Kelp Zone, but still has predators in the form of Blighters, Ampeels, and Warpers. The Blood Kelp Trench consists of a single deep trench with natural rock bridges spanning from one wall to another, plus a small cavern system located below the Bloodvines where their roots can be found. One of the Wrecks can be found in this area, stuck between the trench's walls. This zone is considered unsuitable to explore with the Cyclops due to the trench's narrow width, and an ill-equipped Prawn Suit may get stuck due to this biome's sheer walls and depth. Gel Sacks can only be found in the deepest area of this biome, below 500 meters, in the section below the wreck. Ampeel Eggs can be found at the very bottom of the trench.

8. #8Crash Zoneselective

   Keys: Site, Zone, Area · Secondary: Crash, Crashed ship

   The Crash Zone is the biome in which the Aurora crashed, hence its name. It is characterized by rocky slopes, mesas near the southern edge, and deep trenches covered with sand. The biome is littered with debris from the crashed spaceship. This biome is one of the most dangerous biomes due to its open spaces, murky brown water, crumbling wreckage, and the presence of ten Reaper Leviathans. The Crash Zone is currently the largest biome in 4546B's topics. The Crash Zone is located on the easternmost part of the Crater, surrounded by a Kelp Forest, Safe Shallows, the Bulb Zone, a Mushroom Forest, the Crag Field, and a Grassy Plateaus. There is a large amount of dry land on the eastern side of the Aurora which has a large amount of debris and Metal Salvage. Flocks of Skyrays also populate this area. due to the small islands created by the displaced sand. The Crash Zone possesses a distinct sandy, murky tint of water, and is nearly devoid of flora, though the western border that borders the Safe Shallows shares some of its flora. The biome does however have a small variety of fauna, most of which being predatory - including the dangerous Reaper Leviathans. The harvesting nodes found in the area makes this biome a good source for raw crafting materials. A portion of the Bulb Zone goes into the Crash Zone, near Aurora's front section. This small area contains a large amount of limestone and sandstone outcrops. It is guarded by a Reaper Leviathan. If attempting to enter the Aurora, it only takes a brief trip through deeper waters, but a Reaper Leviathan prowls near the entrance. A portion of the ship's upper floors dips into the ocean, allowing any survivors to enter the ship.

9. #9Crater Edge

   Keys: Void, Crater Edge, Ecological Dead Zone

   Maximum depth unknown. Temperature averages 5-10℃. The Crater Edge, also known as the Void, is the area surrounding this crater. With no resources and extreme danger, the Crater Edge proves a completely impassible, inhospitable barrier. Adult Ghost Leviathans live in the Crater Edge, where they subsist off of microorganisms and creatures straying outside of the Crater. When entering the Crater Edge, a single Ghost Leviathan attacks at first. If you stay in the Crater Edge longer, two more adult Ghost Leviathans will emerge from the depths to attack. The Crater Edge is a large open ocean devoid of any flora, coral, or all but one non-microscopic fauna species: the three adult Ghost Leviathans that attack when you enter the biome.
