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.
