TABLE II. Relative abundances of Chromodoridinae from three sites in the Sea of Cortez and west Mexico: Bahía de los Ángeles, Baja California (data from Bertsch, 2008), La Paz region, Baja California Sur, Gulf coast and Isla Cerralvo (data from Angulo Campillo, 2003, and Bertsch pers. obser.), and Bahía de Banderas, Jalisco-Nayarit (data from Hermosillo González, 2006; see also Bertsch, 2011). Numbers and percents of nudibranch specimens observed during 1-10 year long term studies. Type localities of the species are given in parentheses. *Note that Hypselodoris ghiselini is considered a Gulf of California endemic.
