Conus dalli


Tropical Eastern Pacific


Distinctive pattern of rounded white triangles, on a red-brown background. Found in sand pockets of reefs. Very similar to Conus textile (Textile Cone) from the Indo-pacific region, differing mainly in location. Like many other Conus species, predatory, able to fire a tiny venomous 'harpoon'. Should not be handled live.


Max Size: N/A cm

Sea Temperature Range: 27.9-29.8°C

Depth: 0-50m

Habitat Generalization Index: N/A

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Least Concern

Occurrence: Infrequent (2.1% of sites)

Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed

Abundance: Solitary (1 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
