Zombie Snail

Common Name: Zombie Snail
Scientific Name: Nassarius spp.
Colouration: Smooth, elongated spiral shell in shades of beige, brown, or grey
Movement: Burrowing scavenger using a muscular foot and long siphon to detect food
Preferred Habitat: Sandy and muddy substrates in shallow marine environments
Diet: Detritus, decaying organic matter, leftover fish food
Ecological Role: Detritivore; stirs and aerates substrate while removing excess organic waste
Compatibility: Well-suited to the Living Ecosystems Aquarium and Living Sand beds, particularly in tanks with fish and regular feeding

The sustainably sourced Zombie Snail (Nassarius spp.) is a fast-moving, sand-sifting detritivore known for its ability to rapidly locate and consume decomposing matter. It plays a key role in waste processing and aerating the substrate in reef systems.

In natural environments, Nassarius snails contribute to the health of benthic ecosystems by removing detritus and uneaten food before it breaks down into harmful nutrients. Their activity promotes oxygenation of the sand and prevents anaerobic dead zones.

In the Living Ecosystems Aquarium, Zombie Snails are a vital part of the clean-up crew, especially in tanks with high fish feeding. Their active scavenging helps prevent nutrient spikes and supports the natural cycling processes of the Living Sand biome.

Reproduction:
In captivity, Nassarius snails may lay small egg capsules, although successful breeding is uncommon without specialised larval care.
