8.81 Underwater sound-locating ability of alligators. Alligators have shown the ability to determine the direction of an air- borne sound. But can they locate underwater sounds? This was the subject of research published in the Journal of Herpetology (Dec. 2014). Alligators inhabiting the flood control canals in the Florida Everglades were monitored for movement toward a sound produced from a submerged div- ing bell. Movements within a 180° arc of the direction toward the sound were scored as movements toward the sound; all movements in other directions were scored as movements away from the sound. Consequently, the rescarchers assumed that the proportion of movements toward the sound expected by chance is 180°/360° = 5. In a sample of n = 50 alliga- tors, 42 moved toward the underwater sound. ive the mut heth p Gttener sound is highe than expected by %3! hativ etheses ftesting higatothat eto b.a ahem apan mate mo k undewate Sme the tetstatisue o hisstudy d.
