Cuban treefrog
Osteopilus septentrionalis (Duméril and Bibron, 1841)


Osteopilus septentrionalis or Cuban treefrog is native to Cuba, Isla de la Juventud, Bahamas and the Cayman Islands. It is a very large warty treefrog that can grow up to 1.1-6.5 in. (2.8-16.5 cm) long, measured from snout to vent. It has large toepads typical to many treefrogs. The color of O. septentrionalis varies from gray to brown to olive-green to blue-green. It has the ability to change color. It is larger than species native to Florida and size is one of the easiest ways to distinguish it from native treefrog species. Noxious skin secretions may help protect it from predators such as birds and snakes.
Life Cycle
O. septentrionalis usually breed in the spring and summer, but in suitable conditions they may breed year round. Reproduction is usually stimulated by warm summer rains. Especially rain associated with tropical weather systems and intense thunderstorms. The number of eggs deposited by a female is related to her size, with larger females laying over 15,000 eggs per season. Any site without predatory fish is suitable for breeding.
Osteopilus septentrionalis have been found in Florida, but it is believed that they have the ability to expand their range into other southeastern states. O. septentrionalis prey on native frogs and toads. They also compete with native species for the available resources both as adults and as tadpoles.
Control Efforts
Report sightings of O. septentrionalis. If you are sure of the identity, then humane euthanization can help control this species around your home.
