About Hypselodoris saintvincentius Burn, 1962
Hypselodoris saintvincentius is a species of nudibranch first formally described by Burn in 1962. It has a dark blue-black body covered in hundreds of small black and white spots. An irregular, lined creamy-white pattern is typically present on its dorsum. Its gills and rhinophores are orange, and are sometimes outlined in white. This species can grow to a total length of at least 40 mm, and individuals have been observed feeding on sponges that belong to the genus Dysidea. This nudibranch is currently only known to occur in Southern and Southwestern Australia. It was originally described from a specimen collected in the intertidal zone at Coobowie, located on the west coast of St Vincent Gulf, South Australia, at coordinates 35.044260°S 137.739888°E. It has also been reported from Western Australia, and has been found at depths down to 12 m. This species is related to Hypselodoris infucata, a widespread tropical species, and Hypselodoris obscura, a similar species found in Australia.
