New theory predicts movement of different animals using sensing to search

CHICAGO, Sept. 22 (Xinhua) -- A Northwestern University (NU) research team has developed a new theory that can predict the movement of an animal's sensory organs while searching for something vital to its life.

The study focuses on South American gymnotid electric fish, using data from experiments performed in lab, but also analyzes previously published datasets on the blind eastern American mole, the American cockroach and the hummingbird hawkmoth. The three senses were electrosense, vision and smell.
