[3] H. auricula also resembles another species called H. antarcticus and as a result of this many scientists go debate on whether or not they exhibit synonymy based on morphological features.

[4] H. auricula is 2-2.5cm tall and funnel shaped with a long stalk, a central mouth, and eight radiating arms that can have, at most, 100 kidney-shaped tentacles that are found at the tip that is an identifying feature for this species.

[1] This species lives among the mid-eulittoral to shallow sublittoral ranges of an intertidal zone with the presence of adequate circulation for marine eelgrass and other algae.

[5] The more favorable conditions for larval habitat would be similar: a large density of macroalgal species, which is dependent on wave action.

[8] Haliclystus auricula has been found to generally prey on species under the order of Copepods, Amphipods, Ostracods, and Isopods that are often around their attached algae within the intertidal zones.
