In the centre of the Daintree rainforest, Giant White-lipped Tree Frogs Litoria infrafrenata ordinarily call for mates at the beginning of September, but much cooler temperatures persisting until very recently, have delayed the unmistakable clatter of competing males.
They are world’s largest tree frog and have been known to grow to 139mm. Their colour is variable, from beige-brown during the day to bright-green at night. They are conspicuous with a white stripe around the lower jaw continuing through to the shoulder, as well as white stripes (salmon pink in breeding males) on the trailing edges of the lower legs.
In an attempt to mimic the sustained adhesiveness that tree-frogs’ toe-pads provide, a group of researchers in India have created a form of sticky coating that is both strong and reusable. More details can be found in this Scientific American article.
