DR PHIL BISHOP
They don’t develop a tongue so much like the introduced frogs. They tend to lunge at things with their mouth open, and there is a different attachment. Introduced frogs have a tongue that is attached right at the front so it can flick it out a long way, whereas native frogs have their tongue sort of secured at the back, so they can just sort of stick it out a little bit, so they sort of open their mouth and lunge.
