Entity Type Tags

Use the etag:[entity type tag] parameter to more efficiently search for entities included in the tag.

Tags are a Minecraft concept for organizing blocks, items, and entities into groups. There are quite a lot already defined in Minecraft but you can also create your own via datapacks.

For example, etag:minecraft:aquatic would search for any aquatic mobs. See the full list .

You can even supply multiple tags, like etag:minecraft:aquatic,minecraft:boat.

Defining your own tags would be an extremely powerful way to group entity types.
