Anaspidea
The order
Anaspidea, or sea hares, are benthic herbivores that may feed an a
variety of green and red algae as well as cyanobacteria. Cephalic
tentacles and rhinophores are large and flattened. The sides of the
body extend as parapodia that meet dorsally and may or may not be
fused. A small shell is usually present but is often either internal or
concealed by the parapodia. Only one family is known from Hawaii
but it includes some of the largest and some of the most common
opisthobranchs in state waters.
