Grenada is the southernmost island of the main Lesser Antillean island arc. Trinidad is a large island off northeastern Venezuela. It hosts two species of anteaters that are also found on mainland South America. Curaçao is a Dutch island off northwestern Venezuela. Escudo de Veraguas is an island off northern Panama. Despite its small size, it supports two mammal species found nowhere else: the bat "Artibeus incomitatus" and the only extant Caribbean sloth. Pilosans of the Caribbean The mammalian order Pilosa, which includes the
Mammals of the Caribbean connecting South America with one or more off-shelf islands). Colonization of a series of islands can occur either by an iterative rafting process ("island-hopping"), or by colonization of a large ancestral island which is then subdivided by into smaller islands by subsequent geologic or sea level changes (island-island vicariance). The restricted, unbalanced nature of the Caribbean mammal fauna implies that rafting was part of the overall process. This is consistent with the fact that megalonychid sloths, platyrrhine monkeys and caviomorph rodents have all shown a capacity for this type of dispersal (in their colonization of North America from South America
