|Secondary Biomes: None|
Toxic planets can be found orbiting radioactive (yellow), frozen (blue) and fiery (red) star types. Unless players have a Radiation EPP Upgrade equipped they'll perpetually take damage from deadly radiation while on the planet.
The poison ocean found on toxic planets is infinite, and cannot be drained. All air below surface level is replaced with poison. To build underwater and not have poison spawn inside your structure, you must replace the background and foreground with blocks, then remove the foreground blocks and poison will stop spawning.
- This planet is toxic - the air is putrefied and the oceans are poisonous. Radiation exceeds safe levels by a factor of thousands.
- This highly radioactive planet is a poisonous wilderness inhabited by irradiated lifeforms. It's luminescent surface is toxic. An uninviting destination.
- This is a toxic planet replete with radiation. The noxious oceans are lethally poisonous... May I remind you that other destinations are available.
The surface layer of toxic planets is primarily made up of poison ocean with small scattered islands made from mud, raw sewage, rusty blocks and waste. Commonly these islands have trees which can be harvested for a plant fibre and toxic waste.

Toxic surface biomes use their own sets of music tracks for day and night.
Toxic planets do not have any sub biomes which appear, and toxic oceans do not appear as a sub biome on any other planet types.
There are no mini-biomes found on the surface or underwater in toxic biomes.
Toxic planets deviate somewhat from planetary standards due to being ocean-type planets.
- Space: Asteroids
- Atmosphere: Atmosphere
- Surface: Toxic (Primary Biome)
- Note: For ocean-type planets, the surface layer begins at y=1050 and the ocean surface is at y=1150 regardless of planet size.
- Subsurface: Toxic Ocean Floor
- Shallow Underground: Tarpit, Mushrooms, Wilderness, Mini Village, Underground 0a, Underground 0b, Underground 1a, or Underground 1b
- Mid Underground: Luminous Caves, Stone Caves, Bone Caves, Ice Caves, Underground 0c, Underground 1c, Underground 1d, Underground 3a, Underground 3b, Underground 3c, or Underground 3d
- Deep Underground: Cell Caves, Flesh Caves, Slime Caves, Underground 0d, Underground 5a, Underground 5b, Underground 5c, or Underground 5d
- Core: Blaststone Core Layer, Magmarock Core Layer, or Obsidian Core Layer
Weather in toxic biomes is either acid rain or clear. Weather happens for each planet based on the weights given to the weather types (probability is calculated by dividing a single weight by the sum of all weights); the probability for weather types on toxic planets is as follows:
There are only two harvestable crops found on toxic planets: Toxictop and Kelp. Toxictops can be harvested by interacting with them or by digging them up, but Kelp must be felled like a tree before it can be collected. Toxictop plants drop toxictop and have a chance to drop a seed which can be replanted. Toxictop is found only on the islands in the poison ocean while kelp is found only on the floor of the poison ocean.
The trees on toxic planets can be harvested for plant fibre and toxic waste, but do not drop seedlings so they cannot be replanted. Unlike Kelp on Ocean planets, Kelp on toxic planets drops saplings which can be planted to grow more kelp.
In addition to procedurally generated creatures, there are a variety of unique monsters, bugs and critters found in toxic biomes. Some of these are also found in other biomes, while others are unique only to toxic biomes. While these unique creatures have a chance to appear on toxic planets, they will not all appear on each one. In addition to unique creatures, each biome has multiple types of both procedural ground and flying creatures.
Unique monsters each have combat attacks, and they must first be weakened before capture. Once weakened players can attempt to capture using a capture pod. If successful they can then be released to battle alongside and follow the player.
Critters are smaller non-combat unique creatures which are not capturable using capture pods. They can be captured without weakening them first by using a relocator gun. After releasing a critter from the relocator it will stay in the area it was released into.
Bugs are very small unique creatures which can be captured using a bug net, and are then stored inside placeable jars. Bugs which are captured using a relocator will fly after release instead of being kept inside a jar.
There are a number of fish which can only be caught on toxic planets using a Durable Fishing Rod. These fish won't be seen swimming in the wild without a fishing lure to attract them. A basic fishing rod will not work on toxic planets.
Catching each of these fish will complete their entries in the fishing collection screen.

There are a variety of items which are specific to chests found in toxic biomes. Some of these may have a chance of being found in other places throughout the universe, but they've all been specifically allocated to toxic chests within toxic biomes.

The toxic biome parallax shows ruins of old structures, none of which remain. There are no villages or dungeons found on toxic planets - they're too harsh to support any type of settlements.
