Their biology is mostly unknown, except that they seem to feed exclusively on hydroids.

[1][2] Their body is covered with cerata-like dorsal and lateral outgrowths, with finger-like branches.

Their rounded head shows on each side of the mouth a tentacle, with tiny finger-like papillae.

The sheath of the rhinophore stands high and resembles the dorsal processes.

These nudibranchs are characterized by an unpaired oral gland.
