For that reason, many are seldom seen and poorly known even though some of them are among the most colorful aeolids. Most feed on hydroids and store nematocysts in cnidosacs at the tips of their cerata. However, some  feed on scleractinian corals and do not have cnidosacs. Many species also secrete defensive chemicals from glands in their cerata. This is particularly prominent where it may compensate for the lack of nematocysts. There are about 44 species known from Hawaii in at least four genera (Abronica, Eubranchus, Fiona, and Tenellia). The family was recently revised to include the families Tergipedidae  and  Eubranchidae (Cella, et. al., 2016). We've tentatively assigned undescribed and insufficiently studied Cuthona spp. to Tenellia as per Cella, et. al., 2016.
