Which jellyfish feed by filtering tiny organisms from water?

While many jellyfish are predators that use stinging cells to capture prey, some species engage in filter feeding to extract minute organisms and algae from the water.1

Specifically, members of the order Rhizostomeae utilize this method. In these jellyfish, the mouth is replaced by thousands of minute pores located on frilly, fused oral arms that trail behind the animal. These structures form a spongy area that acts as a filter, collecting tiny organisms and detrital material.21
