Common name : distorted whelks

Aspect : characterized by significant distortion and irregularity in shape; this arises from the growth pattern where each new whorl must expand over a prominent, thickened ridge on the previous whorl, resulting in an asymmetrical, elongated, or "crooked" appearance; range in size from 20–150 mm; outer lip is often thickened and flared; coloration varies from cream to brown with darker spiral bands

Feeding : predatory carnivores (polychaete worms, sea urchins and bivalves)

Environment : inhabit shallow to moderately deep tropical and subtropical marine environments, in the Indo-West Pacific region (e.g., from East Africa to the western Pacific, including Australia and New Caledonia) in sandy or muddy subtidal bottoms at depths of 5–100 m, often among seagrass beds, coral reefs, or rubble
