Java Edition guides/Update Aquatic

This guide is a simplified overview of all the changes in Update Aquatic ( 1.13.x releases), which assumes at least some familiarity with the World of Color Update (Java Edition 1.12.x releases).

New
Several new mobs are added to the game. Here is a list of the mobs to look out for:

Music tracks
Note: these track previews have been shortened to 30 seconds on the wiki due to an agreement with the author to allow them on the wiki

Water
The physics for water have also been changed, and the way the player interacts with water has also changed.

Swimming
There is now an actual swimming animation used by the player while underwater, which can be activated by sprinting underwater. This also allows the player to move in any direction they are looking including down. Players who cannot sprint, i.e. are too hungry to sprint, cannot swim. Crouching underwater also allows the player to descend at a faster rate.

While swimming, players can go through one block gaps similar to when using an elytra.

Item and Experience
Items and experience orbs now float to the surface of water rather than sink, this makes dying underwater easier to deal with because all of the player's items now wait at the surface. This also allows for easy vertical item transportation.

Bubble Columns
For more detailed information see Bubble Columns.

Magma and soul sand now make bubble columns when placed underwater. Magma naturally generates in underwater ruins and where underwater ravines meet lava, while soul sand does not currently generate naturally in oceans. Players are able to breathe while in bubble columns.

Magma bubble columns pull things down to the bottom; this includes items, players, mobs, and boats. Soul sand bubble columns rapidly push all entities, including players, to the surface.

Breath
The breath meter no longer instantly refills when entering air from underwater; this means it is no longer possible to instantly refill the air meter with a torch while underwater.

Vision
Water has been given unique colors depending on the biome they are in.

Water is also now clearer, and the longer the player is underwater the clearer it becomes.
