Leptoconus ammiralis - Striped Maritime Splendor

$12.00

The Admiral Cone Shell, scientifically classified as Leptoconus ammiralis, is a medium to large species of predatory sea snail renowned for its striking pattern and formidable presence. Its name, “ammiralis,” is Latin for ‘admiral,’ a fitting title for a shell with such commanding stripes. This species is widely distributed across the Indo-Pacific, from East Thailand and Japan to Northern Australia, Fiji, and the Marshall Islands. It typically inhabits sandy or muddy substrates, often found beneath rocks or among algae in subtidal zones ranging from 2 to 240 meters deep.

The shell of L. ammiralis is moderately solid to heavy, with a conical shape and an angulate shoulder. The ground color is typically white, overlaid with 2 to 6 broad spiral bands of pale orange to dark brown. These bands are intricately patterned with dark spiral and axial lines, frequently interrupted by distinctive white triangular “tents” that create a dramatic, high-contrast effect. This species is molluscivorous, meaning it preys on other mollusks, and it is known to hunt members of the Strombidae family. Like all cone snails, it employs a venomous, harpoon-like radular tooth to subdue its prey, making it a highly effective marine predator.

  • High-Contrast Mosaics: The bold white tents and dark bands are perfect for creating dramatic visual effects in resin art and inlay work.

Each of these shells is a natural masterpiece, sustainably and ethically collected. As a product of nature, every shell will have unique variations in pattern intensity, banding, and the arrangement of its white tents. These variations are the signature of a truly individual treasure.


Each of these shells is a piece of the ocean’s art gallery, sustainably and ethically collected. They are crafted from natural Spotted Marbled Cone snails (Conus ebraeus), celebrated for their unique, dappled patterns and elegant conical form. Please remember that as a natural product, every shell will have its own unique variations in shape, size, and the beautiful patterns on its surface. These are the marks of a treasure, individually painted by the sea.

gance this shell brings to your home.

  • The subspecies pseudocedonulli is found in the Indian Ocean and can be distinguished by a prominently tuberculate (knobby) shoulder, unlike the typically smooth shoulder of L. a. ammiralis.

  • The radular tooth of the Admiral Cone has two barbs and a long serrated edge, an adaptation perfectly suited for gripping and envenomating its hard-shelled mollusk prey.

  • The intricate pattern of white tents and dark bands is not just for show; it provides excellent camouflage on the sandy and rocky seabeds where it hunts.

  • Despite its beauty, the Admiral Cone is a serious predator. Its venom is potent enough to quickly subdue other mollusks, showcasing the evolutionary arms race of the sea.
