Conus martinianus is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones.[1]
These snails are predatory and venomous. They are capable of "stinging" humans.
The size of the shell attains 50 mm. The spire can have a regular conical shape or convex and contains 12 whorls with rather deep, punctulated striae. The smooth body whorl is obtuse at its summit and shows a small number of grooves at its base. The aperture is narrow and becomes almost imperceptibly wider at its anterior extremity, ending in a rather deep indentation. its color is uniform dark brown to lighter brown, interrupted in older specimens by narrow, longitudinal white bands.[2]
This marine species occurs off the Philippines and off the Solomon Islands.
