AA << present behavioral and neurophysiological evidence that [Jumping spiders (Salticidae)] perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large (∼3 m) and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressure level (SPL) >>
<< Behavioral experiments with the jumping spider Phidippus audax reveal that these animals respond to low-frequency sounds (80 Hz; 65 dB SPL) by freezing—a common anti-predatory behavior characteristic of an acoustic startle response >>
<< Neurophysiological recordings from auditory-sensitive neural units in the brains of these jumping spiders showed responses to low-frequency tones (80 Hz at ∼65 dB SPL)—recordings that also represent the first record of acoustically responsive neural units in the jumping spider brain. Responses persisted even when the distances between spider and stimulus source exceeded 3 m and under anechoic conditions. >>

FonT: sarebbe interessante valutare se e quanto tempo prima la struttura neuroacustica del Phidippus audax sia in grado di percepire e discriminare le basse freq dei movimenti tellurici profondi che successivamente manifesteranno macro episodi di superficie (earthquake).
