The sea nettle (Chrysaora fuscescens) is one of the most fascinating creatures of the open ocean. These jelly fish, as they are commonly known, are invertebrates with tentacles up to 15 feet long and a bell of up to 3 feet in diameter. Their deadly sting paralyzes their prey which includes pollock, plankton, and other jellies, and they can travel as much as 3,600 feet up and down in the water daily in search of food.

This image was made at the Monterey Bay Aquarium, which is a wonderful place to experience the undersea world without getting wet! The graceful movement of the jellies is mesmerizing to watch and the large displays offer unlimited possibilities for creative photography.
