Gracing our shiny year-end cover this month is a group of Pacific sea nettles Chrysaora fuscescens featured in the “Jellies Invasion” exhibit at the National Aquarium in Baltimore.

Our cover story, “Feeding Jellyfish: Problems and Solutions” (p. 90) tells of the trial-and-error search for the best way to feed captive jellyfish—the type of research typical to any vanguard investigation in the aquarium hobby.
