What senses do clawed frogs use to find their food?

[tgampper]

Silurana tropicalis is one of my favorite species. Genetically, they are more closely related to the genera Pipa (South America) and Hymenochirus (dwarf clawed frogs, Afirica) than Xenopus. The genus Siluriana was resurrected a while ago. For the most part, the Pipids are both scavengers and hunters. Eyesight is poor and they rely on olfactory stimuli to detect food sources over far greater distances than other species of frogs and toads. The frog's lateral line system is very efficient in detecting waves in the water and will quickly orient itself in the direction of the source.

If you are interested in the frog's sensory perception, read Sensory Perception and the Lateral Line System in the Clawed Frog, by Andreas Elepfandt. He also wrote several articles on underwater acoustics. You can do a Google Scholar search for the articles.
