They use these tentacles (features analogous to legs in terrestrial animals) to prey on fishes and other organism like tiny darts they consume, but they can also use them as a means of defense. The small Jellyfish get caught up and they are small enough to be consumed. They live both in the deep ocean and offshore. One other species is occasionally found in the same geographical range as Aequorea victoria; this other form has been called Aequorea coerulescens. The bioluminescence of jellyfish varies from species to species. These jellyfish, in turn, are food for other species such as the sunfish, thus contributing their grain of sand to the balance of the ocean ecosystem. Arai and A.
