Abstract
Predator avoidance is critical to fish survival and yet multiple types of predator response are rarely recorded at the level of individuals let alone studied in detail. Behaviour of an individual adult male dragonet, Gross's stinkfish Callionymus grossi (Ogilby 1910) (Family Callionymidae) was observed over the course of four consecutive daily snorkelling sessions on high tides in the Maroochy River estuary, Queensland, Australia. On two occasions, the dragonet buried in the sand in the presence of a great barracuda, Sphyraena barracuda, whereas, smaller benthic predators or competitors and the observer sometimes provoked dorsal fin raising and fleeing responses of the dragonet. The dragonet, therefore, demonstrates multiple responses to potential predators and competitors seemingly depending on the likely severity of interaction. Further research of dragonet fishes is recommended to disentangle the functionality of fin display in this group, with the anti-predator function of fin displays and honest signalling of chemical defence a promising aspect for investigation.
期刊介绍:
Austral Ecology is the premier journal for basic and applied ecology in the Southern Hemisphere. As the official Journal of The Ecological Society of Australia (ESA), Austral Ecology addresses the commonality between ecosystems in Australia and many parts of southern Africa, South America, New Zealand and Oceania. For example many species in the unique biotas of these regions share common Gondwana ancestors. ESA''s aim is to publish innovative research to encourage the sharing of information and experiences that enrich the understanding of the ecology of the Southern Hemisphere.
Austral Ecology involves an editorial board with representatives from Australia, South Africa, New Zealand, Brazil and Argentina. These representatives provide expert opinions, access to qualified reviewers and act as a focus for attracting a wide range of contributions from countries across the region.
Austral Ecology publishes original papers describing experimental, observational or theoretical studies on terrestrial, marine or freshwater systems, which are considered without taxonomic bias. Special thematic issues are published regularly, including symposia on the ecology of estuaries and soft sediment habitats, freshwater systems and coral reef fish.
