The diet of all three species was primarily osteichthyans, but with some cephalopods and chondrichthyans. However, chondrichthyans and cephalopods were consumed by O. halei in small numbers, but made up a large proportion of the total mass of the stomach contents. Prey taxa were mostly demersal, only two prey groups (Carangidae and Scombridae) being identified as pelagic. When quantified by mass, Gymnothorax prasinus (green moray) was the most prominent prey item, followed by P. auratus (snapper), Girella tricuspidata (blackfish), and unidentified bony fish. The TL we calculated for wobbegongs (4.24) is similar to that of an earlier study (4.3; Chidlow, 2003), and is the highest of the Orectolobiformes (average 3.6, maximum 4.1; Cortés, 1999). Recognizable prey items were identified to the lowest taxon possible, using reference collections of fish otoliths (78 Australian species) and cephalopod beaks (∼20 species) held at the South Australian Museum, and reference guides (Smale et al., 1995; Lu and Ickeringill, 2002). Wobbegong Shark Size: The maximum length of the wobbegong is recorded about 3 m. They are commonly known as the "Carpet shark". Wobbegongs with empty stomachs or bait only were common (ca. Graduate School of the Environment, Macquarie University. When it comes to hunting sharks have … Although the proportion of empty stomachs was high, the data obtained contribute to better understanding of the diet and feeding habits of wobbegongs and their role in the trophic ecology of NSW coastal rocky reefs. The Wobbegong Shark (Orectolobidae, Carpet Shark)! The MDS plot had a high stress level, indicating a poor fit between actual distance measures and distance in the ordination, so the plot was difficult to interpret and did not show any major trends. 8 0 obj The diets of wobbegongs in NSW waters were dominated by bony fish, with cephalopods and chondrichthyans also important. However, Heidi becomes visible again in open water. Within the bony fish category and when quantified by mass, carangids were the most important prey group, followed by sciaenids, labrids, and kyphosids. endobj uuid:1a279ded-1dd2-11b2-0a00-0ef678d4d7ff Cephalopods were noted as prey of wobbegongs in this study and also by Cochrane (1992) and Chidlow (2003). In Western Australia (WA), Chidlow (2003) found that bony fish were the dominant prey of wobbegongs, with occurrences of 60% and 66.7% in O. ornatus and O. maculatus, respectively. , where O. ornatus, and the ANOSIM suggested that the diet of any Orectolobiformes, explaining their lower TL.
