This closeup of a plume shows the individual polyps in their hydrothecae (note some polyps are open and actively feeding while others are retracted). The large structures are a string of corbulae with the reproductive gonophores (and captive medusae) inside.

This individual, captured off Sares Head in August 2014, is much greener than the other individuals shown. I am not certain if the green is an intrinsic color or if it comes from algae living on the exumbrella. Bell diameter is about 4 cm.
