The ocean biomes are the biggest water surface biomes. They are often the biggest part of the overworld. Ocean biomes will vary in temperature and depth. Often being considered as separate biomes when these changes occur, which is why we’ll look into Minecraft cold ocean biome specifically.
Cold ocean biome
As with other biomes, the ocean one has its own vegetation and materials spawning in. We will find caves easily beneath the surface or even some generally effective mining spots. However, it’s possible to find some open ores in the open, especially when the ocean is quite deep. Depth also determines whether ocean monuments will spawn. These spawn regardless of the ocean’s temperature but require a certain depth to start generating.
Cold oceans are first distinguished by their color in Minecraft. They will be dark indigo. At the bottom of a cold ocean, you can expect mostly gravel blocks with a few sand blocks about. Some dirt can also be found, although gravel will take up the majority of this area.
Vegetation
The ground of oceans will be mostly barren, growing no grass. However, it has its own plants to compensate for that lack of grass. Sea kelp and kelp grow across the bottom of the Minecraft cold ocean, giving some extra items to collect.
Although lighter on diversity, the ecology of underwater plants can be quite different from standard ones we find above ground. Making it worthwhile to pick up a few before emerging back to the surface. These plants are perfect for experimenting too, giving us a few more unique materials to play with.
Mobs
In the underwater areas, we will find none of the usual mobs. Instead, they are replaced with unique ones. Squids, fish, dolphins, and turtles are present throughout water areas, offering a passive presence with easily gatherable materials.
As far as hostile ones go, the drowned mob will be the most common enemy found under the sea. They come with the trident variant, which can kill you quite fast. Keeping out of their reach and striking after they swing is the best way to survive far longer in underwater encounters.
The difference in location can make fighting more difficult. Overall mechanics of underwater areas can make fights harder. Among those problems, we can definitely experience swim speed as one of the problems. Different speeds on land and sea can be hard to adjust to once we switch from one to the other.
Considering we fight underwater mobs less often, their patterns can be harder to distinguish. When fighting in these conditions, take extra care. It’s better to prolong a fight by a bit than lose it, especially if we’ve already stocked up on items from the ocean.
