3. San Diego's Glowing Tide
A bit of magic touches the San Diego shores every few years. Millions of phytoplankton turn the waves a glowing blue at night due to a phenomenon called bioluminescence. The phytoplankton, called dinoflagellates, look red in daylight, which is why when they appear in mass it’s called a "red tide."
As a matter of fact, dinoflagellates' nighttime glow is the result of a defence mechanism when they start glowing as an organism tries to eat them, attracting even bigger creatures to come chase the predators away.
