5. Rapid Reproduction

Cuban tree frogs have a high reproductive rate and can lay a large number of eggs during the breeding season. This, combined with their ability to adapt to a wide range of habitats, allows them to quickly establish thriving populations in new areas. Their rapid reproduction can further exacerbate their impact on native species and ecosystems.

How to Identify a Cuban Tree Frog

If you live in an area where Cuban tree frogs are present, it’s essential to know how to identify them. Here are some key characteristics that can help you distinguish them from other frog species:


Cuban tree frogs are typically large frogs, measuring around 1.5 to 5 inches in length. They have smooth, warty skin that can range in color from light tan to dark brown or gray. One distinguishing feature is their bulging eyes with vertical pupils.

These frogs also have adhesive toe pads that help them cling to vertical surfaces, such as trees or walls. Their toe pads are larger and more pronounced compared to other tree frogs.


The call of a Cuban tree frog is loud and distinctive. Males produce a deep, resonating “brraaark” sound that can be heard for long distances. Their calls are often described as similar to the sound made by a rubber band being plucked.

Size and Folds

Adult Cuban tree frogs are larger than most native American tree frogs. Their bodies are thick and bulky, and they have well-developed, muscular hind legs. They also have noticeable skin folds on their backs and sides, giving them a slightly wrinkled appearance.

If you encounter a frog that matches these characteristics, there’s a good chance it could be a Cuban tree frog. However, it’s always best to consult with a local expert or herpetologist to confirm the identification.

What Do Cuban Tree Frogs Eat?

The primary diet of Cuban tree frogs consists of insects. They will eat beetles, ants, moths, flies, and other small insects that they can catch. These frogs are excellent hunters and can quickly snatch their prey with their long, sticky tongues.

In addition to insects, Cuban tree frogs are also known to eat small vertebrates. They will consume small lizards, frogs, and even other tree frogs. They are opportunistic feeders and will take advantage of any food source that presents itself.

Where Do Cuban Tree Frogs Live?


In Florida, Cuban tree frogs have become highly invasive and pose a threat to the native ecosystem. They have been able to establish populations in various parts of the state, particularly in the southern region. Due to their adaptability, these frogs can survive in a range of habitats, including suburban neighborhoods, agricultural lands, and natural areas.

Hawaii and the Caribbean Islands

Cuban tree frogs have also been introduced to Hawaii and the Caribbean islands, where they have become invasive and negatively impacted the local wildlife. In Hawaii, they compete with and prey upon native frog species, leading to declines in their populations. Similarly, in the Caribbean islands, Cuban tree frogs have been known to outcompete and displace native tree frogs.

Habitat Requirements

Cuban tree frogs require moist environments to thrive. They are commonly found near bodies of water, such as ponds, lakes, and swamps. They also seek out shelter in trees, shrubs, and human-made structures, including buildings and houses. These frogs are excellent climbers and are often observed on walls, ceilings, and even windows.
