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).

Looks like a domesticated rabbit that was abandoned here. Totally out of place -- and it never moved as we drove by in a Jeep ("hey, was that a black rabbit?!"), backed up, got out, and took a few photos.
