From D&D Wiki
Swarm of Bioluminescent Plankton
Medium swarm of Tiny beasts, unaligned
Damage Resistances bludgeoning, piercing, slashing
Swarm. The swarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a Tiny plankton. The swarm can't regain hit points or gain temporary hit points.
Variable Illumination. The swarm sheds bright light in a 5- to 20-foot radius and dim light for an additional number of feet equal to the chosen radius. The swarm can alter the radius as a bonus action.
Water Breathing. The swarm can breathe only underwater.
Found in the deepest oceans, swarms of bioluminescent plankton are made up of countless minute creatures that emit a slight glow. They form a crucial part of the ecosystem, as they are fed upon by many larger creatures, which are in turn eaten by others.
