The clicks of Yangtze finless porpoises ( Neophocaena asiaeorientalis asiaeorientalis ) from 7 individuals in the tank of Baiji aquarium, 2 individuals in a netted pen at Shishou Tian-e-zhou Reserve and 4 free-ranging individuals at Tianxingzhou were recorded using a broadband digital recording system with four element hydrophones. The peak-to-peak apparent source level (ASL_ pp ) of clicks from individuals at the Baiji aquarium was 167 dB re 1  μ Pa with mean center frequency of 133 kHz, -3dB bandwidth of 18 kHz and -10 dB duration of 58  μ s. The ASL_ pp  of clicks from individuals at the Shishou Tian-e-zhou Reserve was 180 dB re 1  μ Pa with mean center frequency of 128 kHz, -3dB bandwidth of 20 kHz and -10 dB duration of 39  μ s. The ASL_ pp  of clicks from individuals at Tianxingzhou was 176 dB re 1  μ Pa with mean center frequency of 129 kHz, -3dB bandwidth of 15 kHz and -10 dB duration of 48  μ s. Differences between the source parameters of clicks among the three groups of finless porpoises suggest these animals adapt to their echolocation signals depending on their surroundings.
