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

[2] Originally described from Ko Ha, Andaman Sea, Thailand.

[3] This animal can be distinguished by large, conical, bright orange-tipped tubercles scattered over the dorsum.

Below each of the orange tips the tubercles is a band of solid white.

There is a single black line extending down the length of both the rhinophore club and stalk, on the posterior midline.
