Bioluminescent Plankton

Live bioluminescent plankton (Pyrocystis fusiformis) that glows bright blue when swirled or shaken at night. These single-celled marine dinoflagellates photosynthesize during the day and light up in the dark, making them a striking science project, classroom demo, or desk display.

Start with a live culture or a complete starter kit, and keep your culture going long term with our Refresh nutrient solution. Read our Bioluminescent Plankton Care Guide for more.
