Environments

The World of Terraria consists of eleven officially mentioned environment types, also known as biomes.

If you have had a hard time finding these biomes such as the Floating Islands, you can use these tools to help you locate them.

Forest


Forests are where most of the trees spawn. Trees drop Acorns when they are cut down, which can be used to replant them. Natural caves may be found in this environment, although most are not more than 100 feet deep its the best idea to build your house next to a big forest just incase you need more wood for some tools. Usually, the Player will spawn in a forest, near or in.

Monsters


 * Zombie (Night)


 * Doctor Bones (Night) (Rare)


 * Demon Eye (Night)


 * Slime (Day) (Includes blue and rarely the purple variants of the slime)


 * Pinky (Day) (Uncommon)

 * Bunny (Day)

 * Groom (Night) (Rare)

Oceans are large bodies of Water that spawn at both sides of the map.. Oceans often contain chests, they are also the only place you can find Coral.

Floating Islands are masses of land that appear in the sky. Just like forests, you can find trees and grass growing over dirt blocks, with some stone and Ores in the ground. Each Floating Island also has a building made of Copper, Silver, or Gold Brick which contains a chest. In the chest will be a Shiny Red Balloon, Lucky Horseshoe, or a Starfury along with other various items.

Floating Islands are also known as Sky Islands.

Monsters


 * Harpies


 * Zombie


 * Slimes

The Corruption
Main article: The Corruption

The Corruption forms during the creation of a map at a random position. In most cases there are 1 to 3 Corruptions per map. The Corruption spawns higher-level monsters regardless of time and thus should initially be avoided by low-level players. Shadow Orbs can be found here in deep caves called chasms. These chasms can reach all the way to the stone layer.

Monsters


 * Eater of Souls (and its variants)


 * Devourer


 * Corrupt Bunny


 * Corrupt Goldfish

Meteorite
Main article: Meteorite

Meteorites can spawn at night randomly or when you break Shadow Orbs and will land on the map somewhere. Meteorite Ore can be used to make Meteorite bars which can be used to make:


 * Meteor Hamaxe


 * Space Gun


 * Star Cannon


 * Phaseblades


 * Meteor Shot


 * Meteor Armor

Monsters


 * Meteor Head

Underground Jungle
Main article: Underground Jungle

The Underground Jungle is a very remote area of the World. It is often found near or under the Corruption. Like Dungeons, these areas have few dead ends; however unlike Dungeons they are covered in plants. They have special items that are unique to the Underground Jungle which are found in Jungle Shrines, small buildings made of Gold Bricks that are spawned at random locations. You can often find a higher concentration of Ores like Gold, Silver, Iron, and Copper in the Underground Jungle.

Monsters


 * Man Eater


 * Hornet (and it's variants)


 * Jungle Bat (Surface Jungle)


 * Snatcher (Rare) (Usually only on the Surface Jungle or near the surface)


 * Skeleton (when the Underground Jungle reaches the stone layer)


 * Fire Imp (when the Underground Jungle reaches the Underworld)

Dungeons
Main article: Dungeon

Dungeons are enormous buildings found close to the edge of a generated World, spanning many layers deep. They are filled with chests which contain unique items.

There is only one Dungeon in each World, although a player may create new Worlds and plunder the Dungeons to gain additional items. Although as seen in the picture the Dungeon can get cut off by the ocean and only have the Old Man. Digging down through the sand can most often reveal the buried Dungeon.

The Dungeon's upper level is home to an Old Man, which will turn into Skeletron should the player talk to him at night, or summon a Dungeon Guardian if the player attempts to enter the dungeon without killing him first.

Monsters


 * Dungeon Guardian (only if the player enters the Dungeon without killing Skeletron first)


 * Angry Bones (and its varients)


 * Cursed Skull
 * Dark Caster
 * Skeletron (Guardian boss)
 * Blazing Wheel (Immortal)
 * Spike Ball (Immortal)

The Underworld
Main article: The Underworld

The Underworld is a hellish realm (about 3500 Feet below on Large maps and 1700 on Small ones) that can be reached by digging past the stone layer. It is very easily identified by its background of stone with veins of Lava. It is primarily made of Hellstone ore deposits surrounded by Ash Blocks, with extensive pools of Lava. Chests with unique loot can be found here. Hellstone can be used to make molten tools and armor.

Monsters


 * Bone Serpent


 * Fire Imp


 * Lava Slime


 * Hellbat


 * Demon (Rare)


 * Voodoo Demon (Very rare)

Surface Jungle
Main article: Surface Jungle

The Surface Jungle is a tree-filled biome containing decorative vines. The trees here grow without the need to plant Acorns, as long as there is Jungle Grass present. The Surface Jungle typically directly connects to the Underground Jungle. This Biome was added in the 1.0.4 update.

Monsters

 * Piranha


 * Snatcher
