, and in common with other members of the family Membraniporidae has twinned ancestrular zooids
. However, Jellyella
can be distinguished by the presence of intricately branched processes (called spinules) projecting into the zooidal chambers. Jellyella
also have a calcitic

unusual in being a pseudoplanktonic
bryozoan found encrusting floating objects, both natural and artificial. Jellyella eburnea
is common on shells of the squid Spirula
(which become detached from the soft body of the squid after death) and on the shells of the planktonic gastropod Janthina
. Jellyella tuberculata
normally grows on the floating alga Sargassum
. By contrast, most other bryozoans are benthic
, encrusting things like kelp
