Lot Essay

Still veiled in mystery, the evolutionary benefit of the uncoiled form is still not fully understood. It may have been that this species inhabited the benthic zone, and thus did not require a form suited to swimming. The spiny defences would therefore have been necessary to protect a slow moving animal on the sea floor.
