Neptunazurea kempfi is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae.[3]

Taxonomy

This species has previously been placed in the genera Chromodoris (Alder & Hancock, 1855) and Mexichromis (Bertsch, 1977).[4][5], then transferred to Felimare (Ev. Marcus & Er. Marcus, 1967) by Johnson & Gosliner in 2012.[6][5]

The most recent development belongs to Ribeiro et al. (2025)[7], in which molecular and morphological analysis of specimens within Felimare led to the establishment therein of genus Neptunazurea (Ribeiro, García-Méndez, Valdés, Schrödl & Padula, 2025). Neptunazurea kempfi specifically received a full taxonomic review within the study.

Distribution

Distribution of Neptunazurea kempfi includes Florida, Mexico, Costa Rica, Venezuela, Brazil, Puerto Rico and Panama.[5][8]

Description

The body is elongate, narrow, with the posterior portion of foot extending slightly beyond the mantle margin.[5] Background color is bright blue with a thick yellow line around the mantle margin.[5] There is a central white line and a series of large black and white spots extend down the dorsum.[5] Rhinophores and gills are blue, branchial leaves are with black rachises.[5] It is up to 20 mm long.[5][9]

Ecology

Minimum recorded depth is 6 m.[10] Maximum recorded depth is 37 m.[10]
