This is the Spiral Babylon (Babylonia spirata), a marine gastropod mollusc in the family Babyloniidae. Recognisable by its ovate-conical, smooth, thick shell with a prominent spire and a broad, angled shoulder giving a channelled appearance around the whorls. The ground colour is white or cream, adorned with spiral bands or blotches in shades from pinkish-orange to dark brown, and it can reach shell lengths up to around 4.9 cm.

Location:
Indo-West Pacific region. Found in shallow marine habitats from the intertidal zone down to depths of about 60 m—typically on fine sand, mud, or shelly substrates, and occasionally among seagrass beds in neritic zones.

Average Size:
Up to approximately 4.9 cm in shell length.

Family:
Babyloniidae

Species:
Babylonia spirata

Ecological Role:
A carnivorous scavenger, feeding on carrion and organic detritus, burrowing into the substrate and aiding in benthic nutrient recycling.

Reproduction:
Non-broadcast spawner. Development proceeds without a free-swimming trochophore stage; larvae develop within egg capsules and emerge in a more advanced form (typically as veliger or juvenile). Specific spawning or larval duration details are limited.

Conservation Status:
Not globally evaluated or listed as threatened. It is harvested for food and shell, carrying commercial interest, though detailed population assessments are limited.
