Bioluminescence is the production and emission of light by a living organism. On dark nights on Tomales Bay, bluish flickers are visible in the water column, which come from blooms of bioluminescent dinoflagellates. These creatures bridge the boundaries between plant and animal, because they both photosynthesize (plant) and locomote (animal). These little creatures emit short flashes of light when disturbed and can put on quite a show for kayakers. Seasonal schools of sardines and anchovies create a phosphorescent trail in the water, which can be amplified when being chased by seals or Night herons. Experience all this glowing activity at night with famed naturalist Ellen Sampson for an out of this world adventure! Kayak rental included.
