Common in the Solitary Islands Marine Park. All Australian waters including Tasmania. Circumtropical distribution in tropical and temperate waters.
Frequents intertidal and subtidal algal and seagrass habitats.
Specimen pictured 50mm in length, discovered in intertidal rock pool. This species lacks the gland that produces the reddish purple coloured ink found in some other sea hare species. It also is able to use the posterior end of the foot as a temporary sucker, enabling it to extend to reach food sources. Known to reach at least 200mm in length.
