Felimare juliae is a species of sea slug or dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.[1]
This species was described from a specimen measuring collected intertidally at Praia das Conchas, Cabo Frio, state of Rio de Janeiro, Brazil, -22.8708°N -41.9811°W and a paratype, from Ilha dos Papagaios, Cabo Frio -22.8969°N -41.9839°W. Reported from Florida and probably present at intermediate localities in the western Atlantic Ocean.[2]
Felimare juliae is similar in appearance to Felimare picta with a dark blue background colour but is densely covered on the mantle and foot with fine longitudinal orange lines. The mantle has a frilly edge with a marginal orange line enclosing a series of larger pale blue spots and pale blue spots occur amongst the orange lines.
