Did you know that as a species, estuary stingrays shift as much sand as the mass of the Great Sphinx of Giza each year? This shifting of sand is integral to their environment, helping with nutrient cycling, oxygen penetration and other ecosystem services:

NEW STUDY: Ray bioturbation rates suggest they shape estuary processes Grew et al. investigated the role of Estuary Stingrays (Hemitrygon fluviourum) in shaping sediment dynamics within the Brisbane Water estuary in New South Wales, Australia. https://t.co/zYJmR9I6N1

Stingrays' decline could spell trouble for delicate estuarine ecosystems, fisheries - Great write-up of @MollyGrew_ first PhD chapter from @abcnews
abc.net.au
Using drones, aerial imagery, and 3D modelling to map and identify stingray feeding pits on the estuary floor, a study has found they play a significant role in health of estuarine ecosystems.

Excited to share my first PhD chapter! Using drones we found rays turnover 21,000 tons of sand annually in an Australian temperate estuary - a greater mass than the Great Sphinx of Giza! Highlighting the importance of rays to the ecosystem 🌊🥞 https://t.co/laDMfor31p

This study used aerial drones to map daily ray bioturbation activity and extrapolated these patterns using aerial imagery to assess sediment displaced annually by rays during foraging activities at...

Did a bit of public outreach this weekend! It was such a great morning sharing my knowledge of cownose rays with members of the public. Thanks for having me, Joey!
Another massive thank you to all ECRs that gave fantastic presentations at the Blue World funded Sydney Harbour MER activity in Parsley Bay this weekend. You provided the community with a wealth of information and re-ignited our passion to conserve our marine environment.

Last week I spoke to ABC News 24 about Charlotte the stingray, who has become pregnant with no male involvement in a North Carolina Aquarium. You can check out the entire interview here: https://t.co/arg0HDY83O Happy #FlatSharkFriday!

Here's another piece by @mel_pud @WildlifeMag I contributed to on everyone's (or at least my) favourite stingray right now - Charlotte in a North Carolina Aquarium - who's making waves after becoming pregnant with no males around. Happy #FlatSharkFriday! https://t.co/6rhIwawjU8

Rumours of a shark being the father to Charlotte's pups weren’t true – but the real story is still fascinating.
