Table 4. Latencies of single-clicks measured at the experimental temperatures.

Peak	22°C	30°C	22°C repeated
N1	0.99±0.02	1.04±0.08	1.03±0.03
P1	1.49±0.04	1.16±0.02	1.66±0.03
N2	2.03±0.04	1.40±0.03	2.14±0.04
P2	2.81±0.06	2.38±0.10	2.96±0.04

Mean (±S.E.) latency (ms) of negative peaks (N1, N2) and positive peaks (P1, P2) of P. armatulus kept at 22°C, 30°C and 22°C repeated calculated as the time period between the onset of a single click stimulus 32 dB above hearing threshold and the peaks. N = 8, except N2 at 30°C (N = 7) and P1 at 30°C (N = 6).
