The Indian River Lagoon lights up from regular summer dinoflagellate blooms and winter comb-jelly aggregations.
In summer the bioluminescent dinoflagellate Pyrodinium bahamense produces bright blue-green flashes when water is disturbed.
In cooler months comb jellies (sea walnuts and related ctenophores) create a different, often rainbow-like glow.
