Deep Sea Magma zone

The Underwater Magma zone would be a deep sea Biome or underwater cave Biome with a very volcanic theme. Lots of magma and thermal vent blocks as well as extremophile life, like shrimp, and worms. Fish would prey on these, and bigger fish prey on them. Some potentially deadly monsters could lurk in these depths. Bioluminescence plants could dance in the current, providing shelter for creatures to hide. Players would seek this Biome for the drops from monsters and fish. To make this experience less frustrating items should be neutrality buoyant, so players need not chase items to the surface.
