'''''Verconia norba''''' is a species of colorful sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae.<ref name="WoRMS">Bieler, R. (2015). Verconia norba (Er. Marcus & Ev. Marcus, 1970). In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=866658 on 13 January 2016</ref>

== Distribution == This species is found throughout the tropical Indo-West Pacific.<ref name="Noumea Crocea">[http://www.seaslugforum.net/factsheet/noumnorb Noumea norba], Sea Slug Forum.</ref>

==Description== The length of the body varies between 7&nbsp;mm and 25&nbsp;mm. In this species the mantle can vary in color from reddish purple to pinkish orange. The mantle border is creamy white. Just inside the mantle border are a series of reddish purple streaks or smudged marks which are a more vibrant purple than the main body color. Along the midline of the animal is a white patch that matches the white border. This patch sometimes encircles the gills and extends anteriorly between the rhinophores. The line is often broken into two patches anterior-posteriorly. The rhinophores and branchia (gills) have an orange-red tint. Identifying individual purple sea slugs within the genus ''Noumea'' can be challenging because [http://www.seaslugforum.net/noumpur2.htm purple forms exist in several related species].

==Ecology== The food source for this species has not been definitely identified, however this species has been found on coralline alga, which may prove to be part of its diet.<ref name="test">[http://www.seaslugforum.net/find/5074 ''Noumea norba'' food source], Sea Slug Forum.</ref>
