Distribution

This species is found often off the southern coasts of India and Sri Lanka. Populations of animals with similar-looking shells from New Zealand and Australian waters have been assimilated into this species. Occasional records indicate a possible presence of the species in Philippine waters. Further study on this species should reveal its exact distribution.
