We surveyed jewellery, arts-and-crafts and tourist shops in eight towns in Bali, Indonesia, in July 2014, to assess trade in four species of large marine mollusc shells (chambered nautilus Nautilus pompilius, Triton’s trumpet Charonia tritonis, horned helmet Cassis cornuta, and false trumpet Syrinx aruanus). Nautilus, Triton’s trumpet and horned helmet are protected species and cannot be collected or traded legally, whereas commercial trade in false trumpet is subject to strict regulations. We found 465 large shells openly for sale in Kuta-Legian (4 shops), Denpasar (2 shops), Ubud (14 shops), Tampaksiring (5 shops), Nusa Dua (7 shops) and Sanur (9 shops).
