Ocean



The Ocean is a biome found at both left and right edges of a world, comprising both the easternmost and westernmost 676 feet (338 blocks) of the map. It consists of a sandy beach and a large body of water that extends toward the end of the map, with Shell Piles being occasionally generated in clumps. Palm Trees grow on the surface (since 1.2.4), and can be harvested for Palm Wood. Seashells and Starfish are found commonly on the surface and underwater, and can grow over time. Corals also grow on the seabed.

Enemies in the Ocean include Crabs, Pink Jellyfish and Sharks. Squids and Sea Snails rarely appear underwater, and respectively drop Black Ink and Purple Mucus. Critters in the Ocean include Dolphins, Seagulls, Seahorses and Sea Turtles.

Oceans will commonly contain Water Chests with loot pertaining to water.

Oceans have a 1/4 chance of generating Ocean Caves during world generation, which are water-filled tunnels with ceilings made of hardened sand beginning at the Ocean floor. These tunnels have a chance of generating with Water Chests and other standard underground items.

Tips

 * Players exploring the Ocean run the risk of drowning if not equipped with the proper accessories. In addition to plenty of healing potions, items and potions that aid breathing, such as the Breathing Reed and Gills Potion, a Magic Mirror for returning home quickly, and Flippers to aid swimming should be brought along. The Grappling Hook or Ivy Whip may also be of some help in returning to the surface for breath. The Neptune's Shell or any of its upgrades removes the need to breathe altogether.
 * Players may drain the Ocean by tunneling down to the Underworld, where water evaporates.
 * Another way of draining the Ocean is by making an air pocket, emptying a Lava Bucket in it and placing a background object (e.g. furniture) in the lava. Allowing water to flow in will cause it to disappear, as the object prevents Obsidian from being generated.
 * When attempting to preserve the Ocean biome from being infected in Hardmode, simply digging a horizontal gap under the seabed is insufficient because world data extends a little past the edge of the world. The gap must be created vertically along the beach of the Ocean to prevent the spread of Corruption/Crimson or Hallow.
 * The Oceans have a lot of space, making them good places for large-scale builds like arenas and farms.
 * While not currently possible to expand the Ocean biome further inland, it is possible to extend the watery area to the inner edge of the naturally spawning beach.

Trivia

 * The version's Ocean music used to be exclusive to only those versions, but has since been implemented into the  as the Ocean Night theme.
