However, it is usually difflcult to identify the sex of the caller because the individual cannot be seen underwater.
Weddell seals (Leptonychotes weddellii) produce a wide variety of underwater vocalizations, as well as a number of closed-mouth call types in air, which sound very similar to the underwater versions.
This study used surface calls to determine whether Weddell seals produce sex-specific calls or whether there are differences in the attributes of calls made by both sexes.
