[1] Sabia australis typically possesses a conical shell, with colors ranging from white to yellow or orange.

[2] The surface of its shell is usually rough and textured, providing protection against environmental circumstances and serving as camouflage against predators.

The size of its shell varies depending on factors such as age and environmental conditions, but typically reaches up to 30 millimeters in length.

[4][5] Sabia australis is a bisexual species, with its sexual development influenced by the proximity of conspecifics.

[4] For example, if it settles on a host alone, it quickly develops into a female, with its male phase being very short or nonexistent.
