The ghost nudibranch, Lecithophorus capensis, is a species of dorid nudibranch, and is only found in South Africa.

It is a marine gastropod mollusc in the family Polyceridae.

[1] This species is endemic to the South African coast and is found on both sides of the Cape Peninsula from the intertidal to at least 30 m.[2] The ghost nudibranch is an almost transparent animal with a deep body and an opaque white margin.

Its digestive system is visible as a purple mass at the posterior end of its body.

[3] The ghost nudibranch feeds on colonial sea squirts and bryozoans.
