As described by the Monterey Bay Aquarium, these jellies come in a rainbow of colors. Nicknamed the “blue blubber”, this jelly isn’t always blue. Some blubber jellies come in shades of chalky white or plum purple.

Why does this drifter don so many different hues? Scientists still aren’t sure, but they tend to find the bluest blubbers in clear ocean water. In bays and rivers, blubber jellies wear earth tones instead.

While constructing this movie, I noticed the rhythmic pulsing of the blubbers as they propelled themselves around the tank. It reminded me of the similar up and down rhythmic motion of dancers at a rave. Hence, my choice of an electronica soundtrack. If you watch the movie closely, you’ll notice some head banging going on.
