Table 2.
Average and range of prey sizes derived from measured otolith length (OL) for prey consumed by Australian fur seals at Seal Rocks, Victoria, Australia from 1998 to 2014. All equations are from Furlani et al. [24]. The symbol ^ equates to the power of. Total length is the head–tail tip; standard length measures from snout tip to end of last vertebra and fork length from snout to middle of caudal fin rays. F represents female and M represents male.
