All ocean world?

Have survival world going on in a ocean world called Map 11, as mentioned in the minecraft menu

The world doesn't start underwater. You start a regular world and the new aquatic zones appear in the oceans and other bodies of water in the world. If you already have a realm or world created you must travel to a previously unexplored area for any of the
new aquatic content to appear.

If you play in a survival world like I do you have to make a lot of underwater breathing potion to really explore the deep ocean areas.

Everything except new world locations such as mines...strongholds...ravines....bigger oceans....etc

Although the current seed I use isn't all water, (it's got maybe two trees in the whole world) it's got this amazing part out in the ocean where it glows at night. Upon investigating I was surprised to see lava far below the ocean. Naturally curious as to
how lava was flowing freely in the ocean I swam down to investigate. Well almost all of my air bubbles were gone when I got there but when I did just before I was going to drown I fell OUT of the ocean and into a massive cavern below. When I looked up, there
was the ocean above me, pouring into this huge opening in the ocean floor like a giant water fall. The entire ocean was just falling into this massive mountain like cavern below filled with a network of other caverns and lava everywhere. It was an amazing
sight for sure.





I'll have to investigate it further sometime. It looked like a great place to start my own version of "Rapture" down there lol.

That is the beauty of random generated worlds...They can be pretty random. I would love an ocean world to build ships and stuff in.
