  Facts
  • All four species of native frogs in New Zealand are endangered of becoming extinct. There are only small numbers of them found in only a few places in New Zealand like Maud Island, Stephen’s Island and the Coromandel. There are no native frogs on the South Island.
  • The four species of native New Zealand frogs are called Archey’s Frog, Hamilton’s Frog, Hochstetter’s Frog and Maud Island Frog.
  • Three of the four species of native frogs don’t live in or near water; instead they live under rocks and in leaf litter on the forest floor where it’s cool and damp.
  • All the native frogs are very well camouflaged with brown (or sometimes green or red) blotches so that they blend in well with the rocks and leaves.
  • Native New Zealand frogs don’t hear very well as they don’t have external or middle ear structures, so you don’t hear them croak like other frogs.
  • Native New Zealand frogs are also quite small – sometimes only a couple of centimetres long.
 
  Did You Know?
  • The native frogs were named after the people who found them or the places where they were found.
  • The common frog that you’re likely to catch in a stream or pond is either a Green and Golden Bell frog or a Southern Bell frog, which are both from Australia.
  • Frogs like the Green and Golden Bell or the Southern Bell frog can lay between 3000 and 5000 eggs. A frog egg hatches into a tadpole which lives underwater. When the tadpole develops legs the tail is reshaped into the body to help turn the tadpole into a frog.
  • In New Zealand we also have Brown (whistling) tree frogs that are from Tasmania. The sound they make is more like a cricket than a whistle.
  • Nearly all frogs will only eat live food – flies, worms, bugs and beetles that are still alive.
 
  Experiments
Press your tongue up against the roof of your mouth. Can you feel the hard roof of your mouth? This is called your palate. Swallow and feel how your tongue presses up onto your palate to help you swallow.
Frogs don’t have a hard roof to their mouth. To get food down their throats they push their eyes down onto the food!
 
  Investigation
New Zealand Native frogs are very rare, but there aren’t many frogs around at all these days. There are lots of different reasons why frogs are dying out.
As humans develop land to build houses or farms the natural habitat of lots of animals including frogs can be destroyed.
Lots of animals like to eat frogs like cats, rats, stoats, ferrets, possums and even hedgehogs.
Poisons like herbicides and pesticides and other wastes that sometimes contaminate streams and rivers can kill lots of animals like frogs.
There is also a disease that frogs can get caused by a chytrid fungus. To help stop the fungus from spreading always release any frogs or tadpoles that you catch back in the area that you caught them.
