Scottish Nudibranchs iBook

Available here as an iBook

and here for Kindle

A photographic guide to the nudibranchs and other sea slugs recorded around the coast of Scotland. 107 species are described and illustrated, with up to 8 images for each species, including their spawn and food, and general information on the main groups. There are also distribution maps for 102 species and reproductions of the illustrations from Alder & Hancock's 1845-55 monograph for 74 species. All 107 species are illustrated in the Kindle version.

Where species are identified with the genus followed by a sp. number, as in Phestilla sp. 2, the numbers are from Gosliner, Behrens and Valdes: Nudibranchs and Sea Slugs Identification: Indo-Pacific, 2015.

The site has been updated to reflect the taxonomy of the family Fionidae modified according to:
A Radical Solution: The Phylogeny of the Nudibranch Family Fionidae. Cella K, Carmona L, Ekimova I, Chichvarkhin A, Schepetov D, Gosliner TM (2016).
