Circular Ear Shell

Haliotis cyclobates

Haliotis cyclobates, known as the circular ear shell, is a species of sea snail characterized by its nearly circular and elevated shell, which can reach a size of up to 60 mm. The shell features a rounded and convex body whorl, with a distinctively elevated spire formed by about three rounded whorls. Its surface is adorned with spiral cords and threads, along with numerous folds radiating from the suture. The coloration includes broad patches or stripes of chestnut-brown, green, and whitish tones, while the inner surface displays silvery hues with red and green reflections. The shell is notable for its five oval perforations, which are slightly raised at the edges. This marine species is endemic to Australia, found off the coasts of South Australia, Victoria, and Western Australia. It typically inhabits benthic environments, thriving in subtropical waters. Although specific depth ranges are not provided, the species is generally associated with rocky substrates in these regions. The circular ear shell primarily feeds on algae, contributing to its herbivorous diet. Its reproductive habits and life cycle details remain less documented, but it is known to reach maturity at a size that can vary. Encounters with the circular ear shell during dives can be intriguing, as divers may observe its unique shell structure and coloration. The species is assessed as Least Concern by the IUCN, indicating a stable status in its natural habitat.
