The crowned nudibranch (Polycera capensis) is a species of dorid nudibranch. It is a marine gastropod mollusc in the family Polyceridae.
This species is found off the southern African coast from Luderitz in Namibia to Port Alfred in South Africa. It is found from the intertidal to 35 m. [1] It has been reported from Australia. [2]
The crowned nudibranch is a smooth-bodied variably coloured nudibranch. The ground colour is white or grey and there are usually black, yellow or orange stripes longitudinally along the notum, though these can be absent. The head has six yellow projections. The gills and rhinophores are black, and may be spotted with yellow. Alongside the gills is a pair of yellow projections. The animal may reach 50 mm in total length. [3] A study using DNA sequencing found that there were two species amongst specimens identified as P. capensis, one of which appears to be the Twin-crowned nudibranch of Gosliner, 1987. [4]
The crowned nudibranch feeds on bryozoans of the genus Bugula . Its egg ribbon is a wavy white collar.
Limacia clavigera, sometimes known by the common name orange-clubbed sea slug, is a sea slug, a species of dorid nudibranch. It is a marine gastropod mollusc in the family Polyceridae.

The giraffe spot nudibranch, Ancula sp., as designated by Gosliner, 1987, is a species of colourful sea slug, specifically a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae. As of November 2009, it remained undescribed by science.
Polycera quadrilineata, is a sea slug, a species of dorid nudibranch. It is a marine gastropod mollusc in the family Polyceridae. The specific epithet quadrilineata means four-lined and refers to the four longitudinal black lines present on the original specimen. This species is sometimes called the fourline nudibranch. In 2020 a integrative molecular and morphological study showed that P. quadrilineata was a complex of two species in the NE Atlantic and one of these species was given the new name Polycera norvegica.
The twin-crowned nudibranch, scientific name Polycera sp., as designated by Gosliner, 1987, is a species of dorid nudibranch. It is a marine gastropod mollusc in the family Polyceridae. As of November 2009, it was undescribed by science.
