Do white sharks become conditioned or make associations with cage-diving boats? Answer: NO We tracked >70 sharks for 4 years and observed an opposite response: habituation, where white sharks response to the boats decreased over time tinyurl.com/3rtd7tk8 led by @Yuri_Niella

I showed the results of aerial surveys of #bleaching on the #GreatBarrierReef to my students, And then we wept.

Just in time for Christmas! Check out my new White's Seahorse Illustration: stickfigurefish.com.au/collections/wh…


This year we've been getting quite a few Eastern rock lobsters (Jasus verreauxi) on our BRUVs, much more than I have seen in previous years. Obviously they are attracted to the bait, this one really didn't want to let go! 😄


The NSW Fisheries Scientific Committee has determined that the Lord Howe abalone (Haliotis rubignosa) is eligible for listing as Critically Endangered under the Fisheries Management Act 1994. To view the determination and make a submission see: dpi.nsw.gov.au/fishing/threat…

Looks like an awesome job opportunity!

We had an unexpected visitor to one of our BRUVs last week whilst sampling off Port Stephens.... #marinelife #oceans 🦭 😎


My contribution to National Science Week is this interview that went live today for the ABC Conversations show. @Aus_ScienceWeek #ScienceWeek If you want to learn about the world of seahorses, then this is the show for you! abc.net.au/radio/programs…


This was definitely one of the more 'interesting' scenes I've captured underwater! 😉

Just two friends going for a swim off Norfolk Island 🦈🐄 Video shown during @icft2023 🎥 @daveharasti



Came across this QLD Groper diving yesterday. Previously I had only ever seen 1 in the region in the past 15 years; this year I have seen 6 at various sites 😎 There seems to be more frequent sightings in southern Australia waters, perhaps another species expanding its range? 🤔
