Description

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.[4]

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.[5]

The maximum recorded length is 300 mm.[6]

A. juliana inhabits tidal pools and seagrass beds, to a depth of 20 metres.[7]
