Squid

A squid is a common aquatic passive mob that spawns in rivers and oceans, and are the main sources of ink sacs, which they drop upon death.

In Java Edition, 2 to 4 squid can spawn in water or waterlogged block from Y-level 50 to 63 (inclusive), as long as the biome is a river or ocean variant. The block above must also be water, and the block below must be water or waterlogged.[s 1] Squid share the water creature mob cap with dolphins and nautiluses.

In Bedrock Edition, 2 to 4 squid can spawn in ocean biomes, and two can spawn in river biomes. In addition, squid spawn only on the surface, i.e. there must not be a solid or spawnable block above the spawn location.
