(CNN) — A large concentration of bioluminescent plankton has formed in the water near San Diego, treating late-night beachgoers to its eerie, electric blue glow. Daniel Humphrey stayed out late on Monday night to take these photos of the bioluminescent waves at Torrey Pines State Beach near San Diego. It's actually called a red tide because the reflection of light off the tiny creatures' bodies gives the water a red tint. Jamie Feldman says the bioluminescent glow from the red tide near San Diego is mezmerizing. The last red tide in the area was in 2013 and lasted a week.
