Article Synopsis
- * Over 1.2 million DNA sequences identified six classes from 80 different taxa, showing that sea lions are opportunistic eaters primarily consuming demersal species, with commercially important species like southern calamari and western rock lobster detected in less than 25% of samples.
- * The research highlights significant diet differences across sampling locations, enhancing understanding of sea lion prey and demonstrating the effectiveness of noninvasive scat analysis for studying regional biodiversity.
Reliable methods for identification of individual animals are advantageous for ecological studies of population demographics and movement patterns. Photographic identification, based on distinguishable patterns, unique shapes, or scars, is an effective technique already used for many species. We tested whether photographs of whisker spot patterns could be used to discriminate among individual Australian sea lion ().
