This species of aeolid
nudibranch is about four inches long. It feeds on
hydroids containing zooanthellae,
and stores them in its cerata,
where they live and multiply. The zooanthellae supply the
nudibranch with nutrients. The numerous cerata are shaped
to supply maximum surface area for the zooanthellae to
thrive. This aeolid is usually found in shallow water
where the sunlight needed for photosynthesis is most
intense. |
