Socotra: Socotran Tree Snails En Masse

A very bizarre phenomenon that can be witnessed on Socotra are thousands of endemic land snails climbing big trees (either gracing blood trees or the equally large endemic Boswellia). There are various explanations why this happens – either the snails are trying to escape the heat or they are seeking some sort of nutrients and food. Whatever the cause – it’s pretty surreal, as snails cover trunks and thick branches with incredible density, it’s like a Manhattan of snails.
