Inhaltsangabe

Uncover how shells travel the world: from ship ballast to plant shipments, and even in the bones of timber and soil.

This concise, evidence‑based study explains the varied ways land and freshwater molluscs spread far from their homes. It covers natural means of dispersal and the notable role of human activity, including shipping, ballast, horticulture, and transport of plants. The text focuses on real observations and examples to show how shells and their eggs can hitch rides across oceans, continents, and even railways, shaping where species live today.

- How molluscs migrate with ballast and cargo
- The role of plants, soil, and garden trades in moving species
- Case examples of snails and freshwater shells found far from their origins
- The evidence for human‑mediated dispersal and its ecological implications
