Euphlyctus hexodactylus

The call is made from the water and consists of a single long watery croak, made up of about 23 pairs of pulses, the first of about 3ms duration and lower in amplitude, the second longer (9ms) and increasing in amplitude with time. Pulses have a dominant/fundamental frequency of 0.9kHz, with spectral sidebands at 2.1, 6.5 and

11.1 kHz. Calls last about .02-0.6 seconds. A different call is made when another male is in close proximity, with energy concentrated between 0.55 and 3.7 kHz. One such call, lasting 4.6 seconds, was composed of pulses from 0.02 to 0.06 seconds which increased in amplitude, culminating in an attack on the intruding male (see figure below). The alarm call of this species is a blood-curdling screech.
