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

The thin shell is striated throughout. The color of the shell is yellowish or violaceous white, clouded.with chestnut, with distant revolving series of chestnut spots and short lines, most conspicuous on two irregular lighter bands.[3]

The shell of Conus brazieri G. B. Sowerby III, 1881 is rather solid, with revolving striae throughout. Its color is whitish, tinged with pale rose-pink, with two broad, light yellowish brown bands, sprinkled here and there with a few very minute brown spots. The spire is conspicuously marked with dark brown blotches.[4]

Distribution

This marine species occurs in the Pacific Ocean off the Moluccas, the Philippines, the Marshall Islands, Solomon Islands and Vanuatu; off Australia (the Northern Territory and Western Australia)
