In some cases, animals do not seem to identify components of complex environmental chemical cues. The pool frog (Rana lessonae) provides an example. After being exposed to a mixture of morpholine and /3-phenylethanol during development before metamorphosis, the froglets prefer the mixture but are not attracted to either of the two compounds (Ogurtsov and Bastakov, 2001). 

Tadpoles of frogs Rana lessonae and Rana esculenta Pike Esox luteus Rinse Swim, rest, edge use Stauffer and Semiitch, 1993... 

Tadpoles of the two closely related frog species Rana lessonae and Rana esculenta respond more to chemical cues of their predator, the pike E. lucius, than to visual and tactile ones. The strongest swimming, resting, and edge-use behaviors - all considered antipredator responses - occurred to a combination of...
