A guide to the nudibranchs and other sea slugs seen during the 1st Nudibranch Festival, 2016 in Anilao in the Batangas region of Luzon Island in the Philippines. Over 490 species are described and illustrated with general information of the families and groups. The iBook has over 1100 many with multiple images. All 490 species are illustrated in the Kindle version. This is the first guide to these beautiful molluscs in this area.

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).
