Population Trend
This species is common in sheltered bays (Kuiter et al. 2002). There is no population information available for this species. It is very rare in southern Japan (Masuda et al. 1975). It is rare in the Calamianes group of islands, Philippines but this may be because of its cryptic habit (Werner and Allen 2000).
