"Discover the dangerous animals"

The island is considered a tropical paradise, including lush, green flowering plants and trees as well as a plethora of animal life. While there are many reasons why people choose to visit the country, one of them is to enjoy the unspoiled tropical terrain. A positive aspect is that there are very few animals that pose a threat to humans. In fact, the country is considered to be free of any type of dangerous snake, which is great positive all on its own. However, the plethora of animals includes endangered species and those that are uniquely indigenous to the island such as the Cuban Spider Monkey and the Tree Frog 

There are over seven thousand different types of insects, five hundred different types of fish, and three hundred different types of fish in and around the island.

Dangerous Animals

As whole, the island is considered to be free of dangerous fauna. However, there are two different species that could potentially cause a threat to a human. While the threat is relatively minor, one should be aware that it does exist.

Cuban Crocodile

Among the animals on the island the crocodile is an endangered species that lives in the swamplands. When it comes to this type of reptile, the Crocodile has a relatively small range, preferring to stay in the swamps, but it is well adapted to land and could pose a threat to humans. The creatures can reach up to ten feet in length and prefer a diet of fish, turtles and other water dwelling creatures. 

The Aedes Mosquito

The second animal danger in the country comes from a tiny insect the mosquito. As well known, the small, buzzing bug can carry a number of different human infections. The most common disease born by mosquitoes on the island is Dengue Fever. This illness causes flu like symptoms that could lead to greater problems, including bleeding, and in severe cases, death. People in Cuba are urged to take steps to protect themselves from mosquitoes, using repellents, mosquito nets, and protective clothing. 

Mammals in Cuba

The Prehensile Tail Hutia is a small rodent creature that is able to use its partially prehensile tail to climb trees within the tropical forests of Western part of the country. This rodent is endemic to the island, meaning it cannot be found elsewhere, and is considered endangered. The animal is no threat to humans, existing off a diet strictly of fruits and vegetation.(1)

A species of shrew, the Cuban Solenodon was once considered extinct, yet has recently been found to be alive by seriously endangered. This tiny animal lives off the insects that can be found within the thick undergrowth of the forest floor. The Solenodon is a nocturnal creature.(2)

While not indigenous to the island, the Indian Mongoose is found in a decent sized population in Cuba. These small animals were introduced to the island by humans to help control the population of nuisance rodents. The mongoose feeds on many small creatures, including snakes. (3)


The smallest frog in the world measures 10mm and is found on the island.


The island is home to a few different species of bats, including the Bulldog Bat, the Pallid Bat, the Fruit Eating Bat, and the Funnel Eared Bat. These nocturnal flying creatures feed off fruits, vegetation, and insects. They do not pose a threat to humans or other animals. Huge colonies of bats can be found inside the Caverna de Santo Tomás (Saint Thomas Caves) in the Pinar del Rio province, the most extensive cave sytem on the island.

The bats became one of the most famous Cuban animals as the logo on the Bacardi rum bottle.

Taranatula Cuba

The Tarantula

There are thousands of different insects on the island, and most of them are harmless to humans. An animal that may seem quite frightening but is not dangerous is the Tarantula. an Arachnid. 

There has been research done indicating that there are over twenty-one different species of Tarantulas indigenous to the island alone. The spiders tend to prefer the tropical trees as their home and prefer a diet of insects. 

The tarantulas tend to stay in the forests, but can occasionally be found in human habitats, which can seem frightening to tourists, but are not dangerous.
