[3]
Description
The maximum recorded shell length is 301 mm.[2] The shell of Cassis tuberosa is typically cream colored with dark brown spots. The dorsal surface will have fine growth lines and fine spiral lines to create a "canceled effect".[3]
Habitat
The minimum recorded depth for this species is 0 m.[2] and maximum recorded depth is 27 m.[2] The species resides in shallow coastal waters around sandy beaches, as well as reef environments. It lives in tandem with seagrass beds, macroalgae banks, rhodolith beds and coral rubble.[3]
Human use
The shell of this species has been used for creating cameos.
The attractiveness of the shell is one of the main reasons C. tuberosa is taken for human use. Due to their preference for shallow waters, they are easily accessed by tourists.[4]
