About Aplysia juliana Quoy & Gaimard, 1832
This species, a sea hare, lacks a purple gland, so it cannot produce ink, and only releases milky secretions. The posterior end of its foot functions as a sucker. Its color is most commonly brown with paler spots, but it can also come in a range of other shades, including solid all-black. The maximum recorded body length of this sea hare is 300 mm. This species has a cosmopolitan, circumtropical distribution across all warm seas. It lives in tidal pools and seagrass beds, and can be found at depths down to 20 metres.
