This is a small nudibranch, with adults only growing to about 12mm. The body is translucent white, with scattered brown or green pigment on the back and cerata. The cerata have 2-3 rows of tubercles. The tip of each ceras is covered by a pale patch and encircled by a brown-coloured ring. The rhinophoral and oral tentacles are smooth, the tips of these tentacles are white with a sub-terminal brown band. Eubranchus doriae is sometimes confused with Eubranchus vittatus but may be readily distinguished by the presence of tubercles on the cerata.
