If you are interested in related taxa that are not traditionally considered sea slugs (opisthobranchs), please see the lower heterobranch addendum and the marine pulmonate addendum. Both also include some families that have been placed in the Opisthobranchia by some authors.

Although they're not closely related to sea slugs, we've added a prosobranch addendum for Velutinids and other prosobranchs that are often mistaken for opisthobranchs.
