Like all species within the genus Conus, these snails are predatory and venomous. They are capable of stinging humans, therefore live ones should be handled carefully or not at all.
The maximum recorded shell length is 80mm.
The shell is white, with revolving series of spots and irregular or cloud-like markings of orange, chestnut or chocolate, often forming interrupted bands. The base of the shell is grooved. The spire shows a single broad sulcus.
Larval stage
Conus spurius larvae hatch from egg capsules, swim for a couple of hours at most, then settle to the bottom as young adults.
Aided by currents, it is at this larval stage when range extension of the species is achieved.
Habitat
Minimum recorded depth is 0 m. Maximum recorded depth is 64 m.
