I've figured out that certain biomes in Terraria can be transplanted - mine or collect enough materials from the original biome (for instance mud blocks and jungle grass seeds) and then plant them somewhere else at the right altitude (above or below ground). The biome should then take root and the biome's own monsters, music and background will appear. The corrupt and hallow biomes even spread on their own in hardmode.

Are there any biomes that can't be replicated just by transplanting tiles? If I use a pickaxe and hammer to steal a bunch of bricks and wall sections from the dungeon, could I make my own dungeon somewhere else and get dungeon enemies to spawn? What about the ocean biome? Do I just need sand and a big enough body of water for sharks to appear, or will they only spawn near the edge of the map?

Pretty much all of the biomes (using Terraria's liberal definition of "biome") can be moved to another location, within certain limits.

The most extreme example is a Meteor crash site biome, which can exist anywhere, at any height. At the other end of the spectrum, we have the Dungeon, which cannot be moved at all.

Completely immovable

  • The Dungeon, because it requires an unsafe background wall below the Dirt Wall depth (cannot be placed by the player).
  • The Underworld, which is restricted to the very bottom of the map
  • The Sky, which, like the Underworld, is just there at a certain altitude.

Mostly immovable

  • The Ocean is not completely immovable, but very inflexible. It is both restricted to a certain height (above the surface level), and can only exist within 250 blocks from either edge of the map. You can create an artificial Ocean in the middle of the map, but that won't spawn Sharks, nor will it grow Corals. Creating artificial Oceans that sort of float above the real one does work; I have actually done so to farm Corals.

    I wonder if extending the ocean further inland would still have the desired effect? If it does work and you manage to bring the coast in the middle of the map, you might be able to "cut" the ocean in the middle of the extension and you'd be left with an "isolated ocean" in the middle.

    @JeffMercado Nope, it's 250 blocks from the edge. Anything beyond that would just be water on sand.

    Add spider nests to the immovable list. Like the dungeon, they are associated with specific unsafe background walls. Commented Jul 23, 2015 at 0:41

In 1.0.6 they made it so placing dungeon walls and bricks were able to create 'safe' housing. I am not sure if this removes the ability to transplant the dungeon biome but it does seem to imply that. Note that a dungeon requires depth as well as the right blocks however.

Which brings me to my next point. The only other challenges to moving a biome are the ones that are elevation based as there is no way to get around that requirement. For example you can not get harpies to spawn at ground level just by digging a wide open space.

Other areas you mentioned above though? Yeah, no problem. You can create a new jungle just by making one, you can indeed get sharks to spawn by making a large enough body of water (Which is much easier to do with the new mechanical items added to the game).
