What Kind of Baby Frogs Do I Have?

Frogs are amphibians. They begin their lives by hatching out of eggs as tadpoles that live underwater. Frogs will gradually lose their tadpole qualities and begin to look like smaller versions of the adults of their species. There are over 3,900 species of frogs worldwide, so figuring out what kind of baby frog you have may take some effort.

  1. Tadpoles

    • If your baby frogs are still tadpoles, it will be difficult to discern exactly which species of frog you have. The U.S. Geological Survey has put together an identification key for describing tadpoles of the frog families found in the United States and Canada (see Resources). Closely examine your tadpoles and choose the sections that match their descriptions. Doing this reveals the frog family to which your tadpoles belong. You will be better able to figure out their exact species when they progress from the larval to the juvenile stage.

    Male or Female

    • Determining the sex of your baby frogs is difficult, especially when you are unsure of their species. You will probably have to wait until they have matured into adulthood to find out their sex. Male frogs are often angular and smaller, whereas females are larger and robust. Males also often make calling sounds while females are more quiet. Males sometimes develop dark or rough spots on the insides of their limbs and digits during mating season. These nuptial pads help in the mating process. These sex identification traits do not apply to every species.

    Native Species

    • If you know that your baby frogs came from a local source, they will probably belong to a native species. Visit your library to find regional guide books. These texts often list and describe local wildlife species, including frogs. Find the description that most closely matches your baby frogs. Another option is to seek out a local wildlife expert. Government agencies like the Bureau of Land Management and the National Park Service employ wildlife specialists that will be able to identify your frogs for you.

    Exotic Species

    • Use extreme caution if you have reason to believe that your baby frogs belong to an exotic species. Many types of exotic frogs are brightly colored. Some types are also poisonous to humans and animals. Secure your baby frogs where they cannot escape into your home or outside. Refrain from touching them. Check your library for books on exotic frogs, contact a wildlife specialist or consult with a pet store owner that offers frogs as pets. Any of these sources should help you find out whether your frogs are exotic or dangerous to keep.
