Replacing all wild-caught fish with agriculture production would require converting land area bigger than the Amazon rainforest into crops. www.tandfonline.com/doi/full/10....

Christmas cookie cutter shark by Tim Andraka. 🎄

Scientist friends, If you submit a paper for peer review and it gets rejected, consider responding to those comments before you resubmit it elsewhere. Because if you get the same reviewer at the next journal and you totally ignored their feedback, they're now very annoyed with you.

Absolutely horrified at the shooting in Bondi. There is no place for hate in this country, I hope there are serious legislative and behavioural changes at the federal level to ensure this never happens again.

That's a monkfish not a tasseled wobbegong. > The photograph does not show a tasseled wobbegong. Rather, it depicts a goosefish, which is also known as a monkfish or American angler.

Honestly, when will unis and other research orgs collectively say enough is enough, and invoice them for all our unpaid labour that drives publishers MASSIVE profits? The Money in Scientific Publishing danielroelfs.com/posts/the-mo... @danielroelfs.com #KnowledgeSlavery

We knew Ningaloo’s #coral bleaching was severe. But what we found 6 months later was still a shock theconversation.com/we-knew-ning...

"Dead bucket list": great term referring to places we've always wanted to see but have been forever damaged by climate change

I'm so, so tired of reading, reporting on and seeing these results. This was easily one of the prettiest places in the world, forever changed. www.theguardian.com/environment/...

Grateful to spend two days on the Klamath watching chinook, liberated by dam removal, return to streams from which they’d been precluded since the Titanic sank. Fish are everywhere, in numbers that stagger the mind & locations that biologists figured would take years to repopulate. Too beautiful.

Perhaps a dumb milestone, but still amazed to see me hit the 2000 citations mark in Google Scholar. What a wild ride it's been to get to where I am!

Teaching-intensive trimesters can be tough, but it can be so rewarding to look at student feedback. Favourite this trimester: "Vince is the G.O.A.T."

I really shouldn't have to spend extra hours just checking to see if the references in student assessments are all just AI hallucinations. What a collective waste of time AI is for our society!

Did my honours lit review manually back in 1998…took me a full day working till 2am to finish. Then someone said oh there’s this program called endnote that does that for you. Saved myself hundreds if not thousands of hours since.

Use reference managers people. So many wasted hours doing it manually...

100% stand by this.

Time to move marine surveying into the 21st century. Our work demonstrates that underwater drones produce sea cucumber surveys that are equivalent to snorkellers and SCUBA @griffith.edu.au @geonadir.bsky.social @jcu @mq @gbrf link.springer.com/article/10.1...

Eastern Australian humpback whale population now well above pre-whaling levels, report finds - ABC News 🦑🧪🌎

85% of Australians Agree: You Can’t “Shark-Proof” the Ocean. New research (from me) - A new nationwide survey (from me) and collected by YouGov has revealed overwhelming agreement among Australians: shark attacks cannot be completely prevented. #sharkattack #shark #nswpol #qldpol

This great anecdote speaks to the character quality of both Jane Goodall and Gary Larson.

Vale Jane. A giant.

One of my 'hobbies' it taking macro pictures of corals at night. Up close these are always beautiful, alien looking things, often with fluorescent colours. This way, you can see individual coral polyps that make up the colonies!

I am not anti-fishing. I am not anti- shark fishing. But hammerheads in particular are species of significant conservation concern, and one of the worst candidates for “catch and release” of any known fish species. And it’d be nice if media coverage *of hammerhead fishing* mentioned that

Truly incredible that we can make a wetsuit that makes you less vulnerable to getting stabbed before we make one that doesn’t give me a mega-wedgie

Worried about shark bite? We can now produce scientifically tested shark proof wetsuits that reduce the likelihood of traumatic injuries www.publish.csiro.au/WR/WR25019?f...

For those of view wondering, we had evidence this happened for decades before it was ever witnessed. This footage is amazing!

When you're marking student assignments that cite your fish science nerd mates RIP Rob Redford

The fascinating about 99% of living organisms is they're just land for another organism to live on. In this case, most sea cucumbers have little scale worms that scurry across them and call the sea cucumber home.

Some awesome news for your Monday. Critically endangered grey nurse sharks are increasing in number by about 5% a year, the first time the conservation efforts have seemed to work for this species! Still just 1500 breeding adults across eastern Australia... www.abc.net.au/news/2025-09...

Pretty amazing that I can map over 500,000 m2 of reef at 0.5cm resolution in under two hours, and then spit out a digital surface model a day later. Incredible how far drone tech has come in the last decade!

I love being able to hang out with rare and threatened species at Heron Island like this Whitespotted Guitarfish. There are a few that hang around the channel at any one time, and they typically just rest on the sand. Despite their appearances, this is not a shark but a ray!

Drone observations reveal white shark (Carcharodon carcharias) dorsal fins are highly flexible and possible investigatory structures onlinelibrary.wiley.com/doi/10.1111/... 🧪🌎🦑🦈🐠

So grateful to be able to introduce @griffith.edu.au students to one of my favourite places and some rare and fascinating species of Heron Island.

Back in paradise to teach @griffith.edu.au 3rd year marine science capstone. What a place to teach and learn marine science!

"Australia has the second-lowest public expenditure on tertiary education institutions in the OECD…This has resulted in an endless chase for dollars (international students & “the next big thing”) rather than thinking about what an educated Australia should look like” www.smh.com.au/national/nsw...

I've been telling most every academic to drop Twitter and move to Bluesky for over a year. Now there's evidence as to why they should do this.

I shared this obviously-full-of-ridiculously-wrong-nonsense diagram And it’s striking how many AI fan techbros say that the problem is me not understanding the power of this tool No, the problem is that it generates response that are full of ridiculously wrong nonsense and people believe it.

"AI will change medicine", meanwhile, in the real world AI is making doctors worse at basic doctor things

Pretty amazing the surfer was completely unscathed given the good chunk taken out of the board! A white shark is most likely responsible given one was seen via drone just moments later at the same beach

I'll admit, I was skeptical when they said Gemini was just like a bunch of PhDs. But I gotta admit they nailed it.
