It is often confused with Nassarius obsoletus, a cooler water snail less suited to tropical marine aquarium temperatures. Nassarius vibex is a species which is often selected for marine aquaria. A Southern Sinagua site in Verde Valley, Arizona where 'shell played a major role in the economic system of this culture.' Modern uses 1130 to 1275, shell beads were manufactured by the inhabitants of the Exhausted Cave near the Clear Creek Ruins. These beads had previously been thought to be the oldest examples of jewelry. Īll these examples predate several 75,000-year-old Nassarius kraussianus beads which were found at Blombos Cave, South Africa (including some colored with red ochre). A further group of pierced shells, some with red ochre, has been recovered from the Aterian levels at the Taforalt site in Morocco these Nassarius gibbosulus beads have been securely dated to about 82,000 years ago. Two shell beads found in Skhul Cave on the slopes of Mount Carmel, Israel, are thought to be 100,000 years old, whilst another found at Oued Djebbana, Algeria, is believed to be 90,000 years old. Several beads made from Nassarius gibbosulus shells are thought to be the earliest known forms of personal adornment, or even jewelry. The shells of species in this genus have a relatively high cyrtoconoid (approaching a conical shape but with convex sides) spire and a siphonal notch. They often burrow into marine substrates and then wait with only their siphon protruding, until they smell nearby food. Most Nassarius species are very active scavengers, feeding on crabs and carrion as dead fish, etc. These snails usually live on mud flats or sand flats, intertidally or subtidally. Species within this genus are found worldwide. Nassarius would then mean 'someone who uses such a wickerbasket for catching fish'.Įcology Distribution and habitat The name is derived from the Latin word 'nassa', meaning a wickerbasket with a narrow neck, for catching fish.
