Conus chaldaeus
Conus chaldaeus

Conus chaldaeus, common name the worm 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.


The size of the shell varies between 19.7 mm and 59 mm. The color of the shell is white, sometimes rose-tinted, with three or four revolving bands composed of irregular longitudinal dark chocolate or nearly black markings. The black markings are more continuous, so as usually to cover the length of the shell except an irregular white central band. Sometimes those markings are impressed so that the intervening white spaces project granulously or tuberculately above the surface; occasionally also the entire surface becomes dark chocolate with the exception of the white band, and a white spot here and there. These markings also ornament the slightly coronated spire. The aperture is white with clouded bands corresponding with the exterior markings. The surface of the shell is more or less striate throughout, but the striae become more prominent towards the dark stained base.
