Samla bicolor is a species of sea slug, an aeolid nudibranch, a marine heterobranch mollusc in the family Samlidae.

[3] In Hawaii it can be commonly found in Big Island, Maui, Oahu, Niihau, Laysan, Midway and Kure.

[4] Samla bicolor can grow to a maximum length of 20 mm and has a translucent body and white tips to the oral tentacles.

There is an orange band near the tip of the rhinophores and on each of the cerata.

[5] Animals from different regions show subtle differences in coloration and in the shape of the oral tentacles and may be members of a species complex.
