The possibility and probability of over-water dispersal as a mechanism to explain the distribution of terrestrial animal species in the Caribbean has been hotly debated since the early part of this century. Each theory that has been proposed - including land bridges and over-water dispersal - has involved over-water dispersal to some extent in the distribution of animals. Yet many people remain sceptical of over-water dispersal, believing that the use of rafts is improbable, unobservable and consequently untenable. Here we present evidence to support over-water dispersal as the mechanism by which green iguanas colonized Anguilla.
