Pig Frogs are somewhat smaller than Bullfrogs overall, their snout is a bit more "pointed" and their longest toe on the hindfoot is webbed all the way to the tip.
The easiest way to distinguish them at a distance is by their calls. The name Pig Frog is a reference to their pig-like grunt.
I have been fooled before into thinking I was hearing feral pigs when in a pond with Pig Frogs calling.
This Pig Frog was recorded in Pasco County, Florida.
