of the suborder Dendronotacea are a highly diverse group characterized
by rhinophores that have a cup-like sheath. Most have two rows of
cerata (or cerata-like) dorsal processes that are used for respiration.
Dendronotids are predators feeding on a wide variety of other
invertebrates, depending on family. Many can swim by flexing the body
and some (Phylliroidae) are planktonic. At least eight families are
known from Hawaii.
