Rapid surveying of benthopelagic ecosystems with a towed mini-ROV Open
Surveying benthic communities has historically relied on snorkel or SCUBA, but these methods are labour-intensive, inefficient (∼1000 m2 per day covered for one dive pair) and depth-limited (2 of benthic surveys per day, p…

Widespread and Convergent Evolution of Cone Monochromacy in Galeomorph Sharks Open
Color vision is widespread in marine vertebrates but is notably lacking in whales, dolphins, seals, and apparently also sharks. All sharks studied to date possess only a single spectral class of cone and are thus potentially totally color …

Assessing lobster and co-predator feeding rates on barrens-forming sea urchins in South East Australia Open
Globally, key predators such as lobsters are thought to control urchins. In south-eastern Australia, the role of Sagmariasus verreauxi (eastern rock lobster) as a key predator of the native urchin Centrostephanus rodgersii (long-spined urc…

Spiny lobster predation of barrens‐forming sea urchins is not limited by body size, but may be overstated Open
Worldwide, lobsters are considered key predators that control urchin populations. It has been widely reported that lobster size plays a significant role in the size of urchins they feed on, as does the size of the urchin. Generally, it is …

First evidence of microplastic “nurdle” consumption by fish in south-eastern Australia Open
"Nurdles" are small, spherical pellets used in plastic manufacturing which can pollute waterways and there are increasing reports of nurdle ingestion by fishes worldwide. We investigated nurdle occurrence for two ecologically and economica…

Ray bioturbation rates suggest they shape estuary processes Open
Bioturbation of sediments is a key ecosystem service in estuarine and marine ecosystems, and rays (superorder Batoidea: skates, stingrays, electric rays and shovelnose rays) are among the largest bioturbators, modifying their habitat throu…

Can denticle morphology help identify southeastern <span>Australian</span> elasmobranchs? Open
Elasmobranchs are covered in scale‐like structures called dermal denticles, comprising dentine and enameloid. These structures vary across the body of an individual and between species, and are frequently shed and preserved in marine sedim…
