Blue Depths
This is a datapack that improves the Minecraft ocean and river ecosystem by adding new mobs, blocks, and a brand new ocean boss. The new sea creatures include Orcas, Sharks, Sturgeons, Jellyfish, Catfish, and Tuna

The datapack REQUIRES the provided resourcepack to play. [Latest Resource Pack Download]
Blue Depths transforms Minecraft’s oceans into a living, breathing ecosystem, providing new creatures that Minecraft normally wouldn’t add (ahem… sharks).
Blue Depths is meant for players who want a deeper ocean experience without sacrificing performance or vanilla balancing. Players can conquer these new creatures and even raise them as their own, experiencing their life cycles.
Along with that, the datapack also adds a new difficult boss to the game, The Nameless Depth, a being lost to time and forgotten by the ocean.
An in-game guidebook can be crafted using a book and salmon, and provides a much better explanation of all the features.
Fully compatible with multiplayer.
