deluge frog have an awesome power to climb in wet environment near waterfalls , where average tree frogs would be washed away .
research worker compared the gripping ability oftorrent frogs , a class of frogs that hold up in fast - flowing peck or mound streams , to that of tree frogs , and found that torrent salientian were much well at gripping wet , steep and rough surfaces . The frogs ' unenviable secret , the researcher find , involves hugging wet and rough surfaces with their toe , belly and thigh .
Males of the (A) Harlequin Tree Frog (R. pardalis) and (B) the Black-spotted Rock Frog (S. guttatus), a torrent frog, in their natural habitats.
" Torrent frogs stick to very wet and rough surfaces by attaching not only their specialized toe launch area ( like many tree frogs do ) , but also by using their belly and adaxial ( intimate ) thigh skin , " study research worker Thomas Endlein , of the University of Glasgow in Scotland , wrote in a statement . [ 40 Freaky Frog exposure ]
Sir Herbert Beerbohm Tree toad frog can climb still surface , thanks to capillary forces between the fluid molecules between the wet surfaces and the frogs ' toe pads . Yet , puzzlingly , torrent frogs can cleave to surfaces even when there ’s enough piddle to destroy this adhesive bound .
Endlein and his workfellow decided to put the amphibian ' incredible sticking abilities to the test . They locate a specie of torrent frog ( Staurois guttatus ) and trees batrachian ( Rhacophorus pardalis ) on a weapons platform that could be tilted from horizontal to upside - down , and tested how long the animals could cling at different angles , levels of roughness and water stream .
On ironic , quiet surfaces , bothfrogshung on equally well . But on blind drunk surfaces , at both high and depressed flow rates , the torrent frogs adhered at steeper angles than the tree frog — even when their toe launch area were submerged in water , event showed .
The spread out platform was transparent , allowing the scientist to measure the areas of the frogs ' bodies in tangency with the surface .
In addition to their pads , both frog specie seem to practice big parts of their belly and thighs to get a clutches . But whereas the Sir Herbert Beerbohm Tree frogs ' belly and thigh detached from the platform at unconscionable Angle , the cloudburst frogs increased their use of these body parts .
Measurements from a force transducer showed the force on different skin part weakened in pissed conditions by nigh the same amount in both types of frog , suggesting the pelter frogs ' better grasp was due to the greater eubstance area in contact with the surface .
Using a scan electron microscope , the researcher also found that the toe launching pad of torrent frogs are outfit with elongate cells on their edge , with straight channels in between . These channels could allow excess pee to debilitate out , helping the frog keep their grip .
The study was detailed today ( Sept. 25 ) in the journalPLOS ONE .
