Description

Janthina exigua is one of the smallest species of Janthina. Like their congeners, it builds a bubble raft, which is blown by the wind. The snail cannot swin and will drown if it falls of its raft. It waits until a chance encounter with its prey, the Portuguese Man-o-war, Physallia physalis.

This snail has a circumtropical distribution. Often after a storm, you can find many purple snails as well as its host (one beached specimen shown here).

These photos were taken a day before President Obama visited the Bellow Air Force Station, and the beach was closed to the public.
