11 Habitat

12

13 Found throughout New Zealand. Wet lands Streams with reeds Pond weed Wood lands Coastal areas Dams They shelter under rocks (this is where I found my frog) and it was in a stream with reeds

14 Adaptive features They change colour from green to brown in breeding season They will also move to another area if the water is drying out. Have been found in very cold and wet areas and very dry areas. The Southern Bell frog is a very agile climber and they can travel up to a kilometre in 24 hours It is often seen walking a along the highway in Australia

15 Threats It is endangered in Australia and has disappeared from many areas where it was once widespread Disease such as Crytid Fungus Loss of Habitat due to grazing near streams of other animals and droughts and floods Predators such as Mosquito Fish
