fauna of this privileged site is the most diverse of the island.
Among the vertebrate species we can find the rare almiquí
(Solenodon cubanus), representative of Cuban Pleistocene fauna;
the royal woodpecker (Campephilus principalis bairdii); the Cuban
parrot (Amazona leucocephala leucocephala), and the catey (Aratinga
euops), endemic species belonging to the same family of the parrot.
Another curious species that lives here is the sapito guantanamero
(Peltoplrine ramsdeni), a tiny tailless amphibious species about
3 cm (1.2 in) long.
In the zones of Baracoa and Maisí, the easternmost of the
province, there is a mollusk having arboricole habits, the polimita
picta. This species, producing extraordinarily beautiful and colorful
shells, is quite sensitive to changes in luminosity, humidity, temperature
and salinity of the environment reason why it has not adapted to
live in other territories.
