Magus Cone Shell

Conus magus - Intricate Patterned Shells

$45.00

The Magus Cone Shell, Conus magus, derives its name from the Latin for ‘magician’ or ‘sorcerer,’ a fitting tribute to its enchanting and cryptic patterns. This small to medium-sized predatory snail is widely distributed across the Indo-Pacific, from the Red Sea and East Africa to Japan and northern Australia. It is a common inhabitant of coral reefs, often found hidden under rocks or within sandy and rubble-strewn substrates in subtidal zones.

The shell is characterized by its relatively smooth texture and a conical shape with a slightly rounded shoulder. Its ground color is typically white or pale, overlaid with a series of distinct, triangular or tent-shaped markings. These markings, usually in shades of brown, orange, or black, are often arranged in irregular spiral bands, creating a pattern that seems to shift and change with the light. Like a magician performing a trick, C. magus is a specialist hunter. It is vermivorous, feeding exclusively on marine worms, particularly polychaetes. It uses its venomous, harpoon-like radular tooth to strike and paralyze its prey with precision, a feat of natural chemistry that feels like magic.

These are the marks of a treasure, individually painted by the sea.

gance this shell brings to your home.

  • The species name magus is Latin for ‘magician,’ referring to the shell’s spellbinding, cryptic patterns.

  • The venom of Conus magus contains conotoxins specifically tailored to the nervous systems of worms, which is why it is generally considered less dangerous to humans than its fish-eating relatives.

  • When hunting, it can extend its proboscis (the ‘harpoon gun’) to a length nearly equal to its own shell, allowing it to strike prey from a safe distance.

  • The color and pattern of the Magus Cone can be highly variable, with some populations having predominantly orange markings while others are mostly brown or black, making each shell a unique ‘spell’.
