''Hypselodoris bullockii'' is a species of colourful sea slug or dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.〔Bouchet, P.; Caballer, M. (2012). Hypselodoris bullockii. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=560043 on 2012-06-11〕 ''Hypselodoris bullockii'' is quite variable in color. ''Hypselodoris apolegma'', which looks similar to this species (and distinguished by a ''reticulate pattern gradually merging in to the pinkish purple'' 〔() ''Hypselodoris apolegma'' (Yonow, 2001). Sea Slug Forum. Accessed 10 February 2009〕), and was assumed to be possibly a different color form of ''H. bullockii''.〔 However, recent phylogenetic data confirm the distinction of the two species, and suggest a sister species relationship between them.〔Johnson R.F. & Gosliner T.M. (2012) ''Traditional taxonomic groupings mask evolutionary history: A molecular phylogeny and new classification of the chromodorid nudibranchs.'' PLoS ONE 7(4): e33479〕 ==Distribution== This nudibranch is found in the Tropical Western Pacific Ocean and the eastern Indian Ocean.〔() ''Hypselodoris bullocki'' (Collingwood, 1881) - Page 1 Sea Slug Forum.
