Dendronotoidea
These nudibranchs resemble Aeolids. They have tubular sheaths that surround
the rhinophores (rhinophoral sheaths), a mid lateral anus on the right
side, with tufts of gills along the sides of the broad mantle. The head
usually has an oral veil (velum). If there is a mantle skirt is absent
or reduced to a small ridge with paired cerata which range from simple
to elaborate, containing branches of the digestive glands and gills along
each side of the body. Size ranges from 1-30cm. They eat soft corals, anemones
or hydroids. Members of Tethydidae family have no radula and feed on small
crustaceans, caught with a net-like oral veil.
Families include: Tritoniidae,
Bornellidae, Marianinidae, Hancockiidae, Dotidae, Scyllaeidae, Tethdidae,
Phylliroidae and Lomanotidae.
