The Cuban tree frog is a large (up to 4.5” or 12.5 cm in length from head to vent (SVL)) invasive exotic species that was first reported in the Florida Keys in 1927. They likely arrived in cargo ships from Cuba and have since spread all the way to North Florida. They are brown to white in color with occasionally spots on the dorsal side. Froglets often have orange irises. Their large toe pads enable them to climb up the sides of houses and are often seen on windows. They were first reported on Sanibel around 1970 and have spread to most habitats on the island. They are very common around human dwellings. They produce a poisonous liquid from the bumps on their back that deters many animals from eating them and causes burning and eye-watering if rubbed in the eyes, nose or mouth. They are also known to devour our smaller native tree frogs. Their call is a squeaking sound that is reminiscent of rubbing your fingers on a balloon.
