Who we are

The Opisthobranch Newsletter was founded in 1969 with a mission to support scientific and medical research relating to seaslugs (Mollusca, Opisthobranchia, Nudibranchia) and their allies. Starting in 1996, www.Seaslug.com has provided professional and popular information resources and photos from around the world. This is a primary reference source for information about gastropods, marine slugs, seaslugs, anaspideans, lamellarians, heteropods, pteropods, gymnosomatans, opisthobranchs, pyramidellids, nudibranchs, micro-shells & related mollusks.
