Info

Halgerda johnsonorum
Carlson & Hoff, 2000

Halgerda johnsonorum is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Discodorididae.

Very soft and flaccid as compared with the more typical rigid feel of the body of a Halgerda. It is very similar in colour to Halgerda willeyi. The one external difference noted by the authors is that Halgerda johnsonorum with brown spots and lines along the side of the body, under the mantle whereas Halgerda willeyi does not.
