Conus dalli explained

Conus dalli, common name Dall's cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.

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.

Not to be confused with † Conus dalli Toula, 1911 which is, according to Fossilworks, a synonym of † Conus imitator Brown and Pilsbry 1911^{[1] [2]}

Description

The size of an adult shell varies between 32 mm and 80 mm.

The spire is indistinctly grooved. The body whorl is obscurely spirally ribbed below. The color of the shell is yellowish brown, with reddish brown longitudinal stripes, interrupted by four revolving bands of white spots, and occasional white spots on the darker surface. The interior of the aperture is rosy pink.^[3]

Distribution

This species occurs in the Eastern Pacific off the Galapagos Islands, and the Gulf of California to Panama. Type locality: Islas Marias, Golfo de California.^[4]
