List of eulipotyphlans of the Caribbean
# List of eulipotyphlans of the Caribbean

The Caribbean region is home to two unique families of the mammalian order Eulipotyphla (incorporating the now defunct order Soricomorpha), which also includes the hedgehogs, gymnures shrews, moles and desmans. Only one Caribbean family, that of the solenodons, is still extant; the other, Nesophontidae, became extinct within the last few centuries.

For the purposes of this article, the "Caribbean" includes all islands in the Caribbean Sea (except for small islets close to the mainland) and the Bahamas, Turks and Caicos Islands, and Barbados, which are not in the Caribbean Sea but biogeographically belong to the same Caribbean bioregion.

## Overview

About fifteen species of Caribbean eulipotyphlans are known to have existed during the Quaternary, but not all Nesophontes species are universally accepted as valid. However, most of these, including all Nesophontes, are now extinct; the Cuban solenodon is classified as Endangered, while the Hispaniolan solenodon is classified as Least Concern.

The interrelationships of the two Caribbean genera remain unclear. Similarities in skull morphology have led some to propose close affinities between the two, but differences in characters of the teeth are evidence against a close relationship. DNA evidence suggests that solenodons are a sister group to a clade of shrews, moles, and erinaceids, with a molecular clock, providing evidence that the split from the other families occurred in the Cretaceous period, late in the Mesozoic era. How they came to the Antilles is unknown; they may have arrived either via overwater dispersal or via some sort of land bridge from North America, South America, or even Africa, and Nesophontes and solenodons may have different origins.

The genera of Caribbean eulipotyphlans are classified as follows:

* Order Eulipotyphla
   * Family Nesophontidae: Nesophontes
   * Family Solenodontidae: Solenodon and Atopogale
   * Unidentified genus

## Cuba

Cuba, the largest of the Antilles, also has the largest inventory of eulipotyphlans, including five members of Nesophontes and two solenodons.

* †Nesophontes major is known from cave deposits of uncertain age.
* †Nesophontes micrus, the most widespread and large Nesophontes, is known from a single mandible dated to the 14th century CE that was found on the surface of a cave deposit together with Rattus, suggesting recent survival.
* †Solenodon arredondoi is known from Late Pleistocene deposits in western Cuba.
* Atopogale cubana, the only surviving Cuban solenodon, has been confirmed only from eastern Cuba as a living animal, but there are several fossil records in the western part of the island.
* Some fossil cave samples from several localities represent solenodons that are larger than A. cubana, but too small for S. arredondoi. They have been identified as Solenodon cf. cubanus.

## Isla de la Juventud

Isla de la Juventud is a large island south of Cuba.

* †Nesophontes micrus has been recorded from the island.

## Cayman Islands

Two extinct undescribed species of Nesophontes are known from several cave deposits on the Cayman Islands, a British archipelago south of Cuba. The two are similar in morphology, but the species from Grand Cayman is larger than the one from Cayman Brac. They are closely related to each other and to the Cuban–Hispaniolan species N. micrus. The oldest record is from the latest Pleistocene, but they probably arrived there earlier in the Pleistocene, if not in the Pliocene. In the youngest layers of several deposits, Nesophontes is found together with introduced Rattus, indicating that its extinction occurred relatively recently.

## Hispaniola

Hispaniola is the second largest of the Antilles. It is divided into Haiti and the Dominican Republic.

* †Nesophontes hypomicrus has been found together with Rattus and remains from a cave in the Dominican Republic have been dated to the 13th century CE.
* †Nesophontes micrus has also been recorded from Hispaniola.
* †Nesophontes paramicrus has been found together with remains of Rattus; some bones from a cave in Haiti have been dated to the 14th century CE.
* †Nesophontes zamicrus has been found together with Rattus; some remains have been radiocarbon-dated to the 13th century CE.
* †Solenodon marcanoi is known from late Quaternary fossil deposits in southern Haiti and the southwestern Dominican Republic.
* Solenodon paradoxus, the Hispaniolan solenodon (one of two extant solenodons), is known both as a living animal and from fossil deposits throughout much of the island, except for northern Haiti. Separate subspecies occur in the northern (S. p. paradoxus) and southern highlands (S. p. woodi).
* Some chest vertebrae and associated ribs of a mammal, probably a solenodontid, have been found in amber in the Dominican Republic. These are probably not older than the late Oligocene. The animal would have been about the size of Nesophontes, with an estimated body mass of 150 grams (5.3 oz).

## Gonâve

Gonâve is an island off western Hispaniola, part of Haiti.

* †Nesophontes hypomicrus
* Solenodon paradoxus, the extant Hispaniolan solenodon, is known from a recent fossil deposit on Gonâve, but there are currently no known solenodon populations there.

## Puerto Rico

Puerto Rico is the smallest and easternmost of the Greater Antilles.

* †Nesophontes edithae, a large Nesophontes, has been recorded from an Amerindian site, and dated to about 1000 CE.

## Vieques

Vieques is the largest island associated with Puerto Rico; it is located east of the main island.

* †Nesophontes edithae, a Puerto Rican Nesophontes, has been recorded from a kitchen midden on Vieques.

## Saint John

Saint John is one of the main islands of the northern United States Virgin Islands.

* †Nesophontes edithae is known from archeological material.

## Saint Thomas

Saint Thomas is one of the main islands of the northern United States Virgin Islands.

* †Nesophontes edithae is known from archeological material.
