Like all species within the genus Conus, these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.

Description

Apertural view of shell of Conus praecellens A. Adams, 1855,measuring 25.5 mm in height, trawled at 80 fms. off Aliguay Island, in the Philippines.

The size of an adult cone varies between 20 mm and 63 mm. The shell is pear-shaped, broad and angulated at the shoulder, contracted towards the base. The body whorl is closely sulcate throughout, the sulci striate The intervening ridges of the rounded spire are carinate, concavely elevated, The acute apex is striate. The color of the shell is whitish, obscurely doubly banded with clouds of light chestnut, and the spire is maculated with the same. [3]

This is a variable species, yet two distinct forms are recognized: (1) sowerbii form, Reeve, 1849 (a thicker, darker, and more densely spotted form with 2 protoconch whorls), and (2) aliguay form, Olivera & Biggs, 2010 (2.5 pearly white smooth protoconch whorls, more slender, higher spire, rounded shoulders, lighter colored). [4] The sowerbii form is the most common form, and until the late 1990s was the only form typically found and in private collections.

Distribution

This marine species has a wide distribution. It occurs in the Indian Ocean off Madagascar, Réunion, Somalia, India, West Thailand and Western Australia; in the Pacific Ocean from Japan to the Philippines and Melanesia (Papua New Guinea, Solomon Islands, New Caledonia, Vanuatu).
