Symposia and workshops on opisthobranchs

Numerous biologists (malacologists) and citizen scientists, including many scuba divers, study the marine mollusks known as opisthobranchs, which are a large and diverse group of shelled and (mostly) shell-less, saltwater gastropods, the common name for which is sea slugs (including nudibranchs, sacoglossans, etc) and bubble snails.

Meetings of an informal group of opisthobranch scientists have occurred in the past.

Numerous examples are listed on the Sea Slug Forum website.

In 2015, in Southern California, "Sea Slug Day" was October 29, "the birthday of Terry Gosliner from the San Francisco's California Academy of Sciences"[7] (Gosliner is an expert on nudibranchs).
