Surinam Toad Uses Fractal Fingertips as a Touch-Based Fovea to Hunt in Murky Waters
A new study reveals that the Surinam toad, or pipa frog, hunts prey using highly sensitive, fractal-like fingertips that function as a tactile fovea, compensating for poor vision in murky waters. This discovery suggests a shared evolutionary strategy between amphibians and mammals for prioritizing sensory input.
