After all, the watery Northwest seemed like welcoming habitat for bullfrogs. A little too welcoming, as it turns out.
The bullfrog has few predators here, and because it is considerably larger than our native frogs, it not only outcompetes them for territory and food but eats them as well. Where bullfrogs thrive in the PNW, you're unlikely to find any other frog. The big frog is also implicated in the precipitous decline of western pond turtles.
Really, the bullfrog will eat just about anything it can wrap its huge mouth around--the biggest ones even eat ducklings and small mammals such as mice. Like other frogs, they lack teeth, and so swallow their prey whole, using both forelegs to cram in the creatures if necessary. It even pulls its bulging eyes down into their sockets (just as it does when it blinks) and uses them to help stuff the food down its gullet.
Here to stay? 'Fraid so.
