The Intricate Murex (Rock Shell)
Chicoreus brunneus, commonly known as the Rock Shell or Murex Shell, is a striking marine species featured in the commemorative stamp series celebrating the rich biodiversity of the Andaman and Nicobar Islands.
Distribution and Habitat
Chicoreus brunneus is widely distributed across the Indo-Pacific region. It typically inhabits shallow coastal waters, living among rocks and coral reefs. As a carnivorous mollusc, it plays an active role in the marine food chain.
Physical Characteristics
This shell is admired for its bold and highly sculptured appearance, usually growing to a size of 70–80 mm. Its key features include:
- A solid, heavy structure with closely spaced spiral cords
- Prominent spines and fronds giving it a rugged texture
- A large blunt knob on the shoulder
- Dark gray-brown coloration
- A white aperture with a light orange edge
These intricate details make it one of the most visually distinctive shells in the marine ecosystem.
Ecological Role
As a carnivorous species, Chicoreus brunneus contributes to maintaining ecological balance by preying on other smaller marine organisms. Like other molluscs, it is highly sensitive to environmental changes, making it an important indicator of ocean health.
Its presence in the relatively pristine waters of the Andaman and Nicobar Islands reflects the ecological richness and stability of the region.

A Symbol of Marine Diversity
Chicoreus brunneus stands as a fine example of the complexity and beauty of marine life. Its inclusion in the commemorative stamp series serves as a reminder of the need to protect ocean habitats and preserve the delicate balance of marine ecosystems for future generations.
