Acoustic tracking durations should be considered a minimum, since transmitters can remain active for 1,113 days (V13-1H) and 2435 days (V16-4H)
U uncomplicated transmitter implant; C Complicated transmitter implant; NA not applicable; ^a = probable mortality; ^b = dysfunctional acoustic transmitter; ^c = transmitter removed; ^d = actively transmitting as of June 20, 2023.
