Light Wаves? In clаss yоu were аsked tо оbserve an unusual biological phenomenon (e.g. a black lemur self-anointing with a millipede) and then hypothesize what you thought could be happening. Time to do that again, only this time with the phenomenon of bioluminescent waves. In some parts of the ocean humans can see a mysterious glow. This glow is usually intensified by movement; swimming, surfing, or boating through it makes the glow more intense. Scientists have discovered that the glow is caused by dinoflagellates living in the water. Dinoflagellates float near the surface of the sea where they make a living via photosynthesis and the ingestion of other types of phytoplankton; dinoflagellates in turn get eaten by copepods, small marine crustaceans. Dinoflagellates have special structures called scintillons inside their vacuoles that generate this light using an enzyme called luciferase. Generating this eerie blue-green light costs energy and resources. Interestingly, they only generate this light at night and only in response to motion.
