fauna of Cuba is characterized by exceptionally high levels of endemism and biodiversity, a result of the island's long-term geographic isolation. Its ecosystems, ranging from montane rainforests and savannas to extensive coral reefs and mangrove swamps, host a unique assemblage of animals. This insular fauna has evolved with notable adaptations, including miniature species and a lack of large native predators, making it a globally significant biodiversity hotspot.

Endemic species

Cuba's evolutionary history has produced one of the highest rates of endemism in the Caribbean, with a vast proportion of its native species found nowhere else on Earth. Notable endemic vertebrates include the Cuban solenodon (Solenodon cubanus), the bee hummingbird (Mellisuga helenae), and the Cuban crocodile (Crocodylus rhombifer). The island's invertebrate fauna is even more distinctive, with thousands of endemic species of butterflies, land snails, and spiders. This remarkable uniqueness is studied extensively at institutions like the Museo Nacional de Historia Natural and is a focal point for international organizations such as BirdLife International and the International Union for Conservation of Nature.

Mammals

The native terrestrial mammal fauna is sparse but highly distinctive, dominated by small insectivores and rodents. The most famous are two surviving relict species: the venomous Cuban solenodon and the large Cuban hutia (Capromys pilorides). Other hutia species, like those in the genus Mysateles, are also endemic. The only other native land mammal is the Cuban fig-eating bat (Phyllops falcatus). Larger mammals, such as deer and wild boar, were introduced historically. Marine mammals include populations of the West Indian manatee (Trichechus manatus) in coastal waters and the Antillean manatee in estuaries like the Zapata Swamp.

Birds

Cuba is a premier destination for birdwatching, boasting over 370 species, including 28 that are endemic. Iconic endemics include the national bird, the Cuban trogon (Priotelus temnurus), the colorful Cuban tody (Todus multicolor), and the world's smallest bird, the bee hummingbird. Other significant species are the near-flightless Cuban kite (Chondrohierax wilsonii), the Cuban parrot (Amazona leucocephala), and the Zapata wren (Ferminia cerverai), found only in the Ciénaga de Zapata. Important bird areas are protected within the Alejandro de Humboldt National Park and the Guanahacabibes Peninsula.

Reptiles and amphibians

The herpetofauna is diverse, with over 150 species of reptiles and nearly 70 amphibians, most endemic. The Cuban crocodile, restricted to the Zapata Swamp and the Isle of Youth, is critically endangered. The island is famous for its anoles, a genus of lizards with spectacular adaptive radiation resulting in dozens of species like the Cuban knight anole (Anolis equestris). Other notable reptiles include the Cuban boa (Chilabothrus angulifer) and several species of freshwater turtle. Among amphibians, the brightly colored Cuban tree frog (Osteopilus septentrionalis) and the endemic rain frogs of the genus Eleutherodactylus are prominent.

Marine life

The waters surrounding Cuba, part of the Caribbean Sea and the Gulf of Mexico, contain vibrant coral reef ecosystems, notably along the Archipiélago de los Canarreos and off the coast of Jardines de la Reina. These reefs support a high diversity of tropical fish, sea turtles like the hawksbill sea turtle, and elasmobranchs including Caribbean reef sharks and nurse sharks. The Queen conch (Aliger gigas) and spiny lobster (Panulirus argus) are economically important invertebrates. Deeper waters are home to species like the Cuban dogfish (Squalus cubensis).

Insects and invertebrates

Terrestrial invertebrate life is extraordinarily rich, with thousands of species, particularly butterflies, beetles, and land snails. The Cuban giant land snail (Polymita picta), renowned for its vividly colored shell, is a prized endemic. The Cuban emerald (Chlorostilbon ricordii) is a hummingbird, but the name is also associated with dazzling endemic damselflies. Many species are narrowly restricted to specific microhabitats, such as the caves of the Sierra de los Órganos or the forests of the Sierra Maestra.

Conservation status

Many endemic species face threats from habitat loss, invasive species, and climate change. Conservation efforts are coordinated by the Cuban Ministry of Science, Technology and Environment and supported by partnerships with groups like the World Wildlife Fund and Fauna & Flora International. Key protected areas include the Ciénaga de Zapata (a Ramsar site), Alejandro de Humboldt National Park (a UNESCO World Heritage Site), and the Guanahacabibes National Park. Successful programs exist for species like the Cuban crocodile and the Cuban parrot, though challenges remain for critically endangered animals such as the Cuban solenodon and the Cuban kite.
