Due to a lack of numbers, experts added the Cuban solenodon to a list of extinct species in 1970. Walker's Mammals of the World states that members of the genus Solenodon feeds on various fruits and vegetables. They communicate with twitters, chirps, squeaks, squeals, and clicks. The Cuban solenodon is Endangered, and populations of Hispaniolan solenodons are highly fragmented, with the Haitian subspecies restricted to a small area in the western Tiburon peninsula. It is critically endangered through habitat loss and pollution – and because it is used in traditional Chinese medicine. By the 1990s a couple populations persisted in the Dominican Republic, but Haiti’s only population of solenodons was predicted to have only 10-20 years left before it vanished. Resembling a large shrew the Cuban Solenodon was once common all over Cuba but since the introduction f domesticated animals such as dogs and cats these rare creatures have become extremely uncommon and were thought to have been extinct up until a recent discovery in 2003.
