This sea hare has no purple gland and therefore cannot produce ink, just milky secretions. The posterior end of the foot in this species can act as a sucker. The color of this sea hare is very often brown with paler spots, but it can be various other shades including plain black all over. The maximum recorded length is 300 mm.Welch J. J. (2010). "The "Island Rule" and Deep-Sea Gastropods: Re-Examining the Evidence". '' PLoS ONE'' 5(1): e8776. . ''A. juliana'' inhabits tidal pools and seagrass beds, to a depth of 20 metres.
