Name: Seashells of Malaysia
Date of Issue: 11 November 2008

Seashells are the hard, protective layer of a marine animal, typically that of marine invertebrates. Seashells are commonly attributed to marine molluscs which has various sub-categories such as gastropods (e.g. snails), bivalves (e.g. clams), and chitons.

Seashells are commonly found deposited along the sea shore by waves and tides. Only the shells are washed up unto the beach empty and clean, the animal already have died and rotted away or have been eaten by predators or scavengers. Seashells come in a variety of shape, sizes and colours depending on the species. The presence of a particular species in the area is usually indicative of the water quality and hydrology.

Collecting empty seashells by beachcombers is a harmless hobby but majority of seashells are collected alive and in bulk for commercial trade and this exploitation causes negative impact on the rarer species.

The trumpet triton is a very beautiful animal, growing up to the length of a man's forearm. It is the main nemesis of the crown-of-thorn starfish, a voracious giant thorny starfish that is known to kill off large stretches of coral reef. Some people believed that the harvesting of the trumpet triton for its shell, has allowed the crown-of-thorn starfish to proliferate unnaturally, thereby causing damage to coral reefs.
