So you found a toad in your backyard or community and are unsure if it is a friendly native toad or the oh-so dreaded Cane Toad ( Bufo Toads ). Below are a couple pointers to aid in your identification process. After reading everything, if you are still unsure please feel free to reach out with a photo and we will be glad to help!
By far the easiest way for most people to distinguish an adult Cane Toad from other toads is the size. The Cane Toad is a behemoth when compared to the native toads, with the average adult measuring in between 5-9 inches. For comparison the native Southern Toad, which is the largest of all native types can grow to around half that size, with most adults being less than 4 inches in length. In a pinch, a credit card can be used as a measuring device. The average credit card is 3.4 inches in length, and by eyeballing the distance from nose tip to butt and comparing it to the credit card you will have a scale to work with. Most toads in SWFL over 4 inches are going to be Cane Toad.
Poison gland location and facial features
This is where things get tricky, but after learning these two telling features, you will become a Cane Toad identification machine. The Cane Toad has large triangular shaped poison glands that angle downward over the shoulder and a smooth "forehead" area, with no crests present. In comparison, the native Southern Toad has oval or kidney-shaped glands that are in a physically higher location on the toad and two distinct crests in the "forehead" region. Please note that these features start to develop when the toads are around 1 inch in length, before then it is very hard to distinguish between the two.
Cane Toads have a very distinctive call and are often heard in the evenings, particularly after a heavy rainstorm. Interestingly, while you may hear the calls one night and not another know that the Cane Toad are present year round. The Cane Toad is quite content to find a well maintained piece of land with year round access to water and settle in for the long haul.
