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.

Calling all isotope ecologists. IsoEcol 2026 will be held between October 12-17th, 2026 at the University of Hong Kong See www.isoecol.com/2026/ for more

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!

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!

Bluesky now platform of choice for science community - Ars Technica | Media coverage of our new paper

"Sponges are the only animals that if broken down to the level of their cells, can reassemble themselves. A sponge is passed through a sieve to break apart its cells. The cells recognize each other and reform into small new sponges." #shapeoflife #spongeThursday youtu.be/ORV3qV8GFF4?...

Academia may not give you job security, flexibility, or wealth, but it will let you unexpectedly connect to eduroam in foreign cities

"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.

Hi, anyone who wants to fire my colleagues in the humanities can go directly to hell. Please no one assume “scientists” are signing on for this just because one dumbass did. The humanities are essential. We absolutely can’t do without them as educational institutions or as a society.

Here is yet another example of marine protected areas benefiting fisheries news.mongabay.com/2025/08/enco...

So, so true.

Nature giving some good material for your next horror flick as per usual. Barnacles (normally filter-feeding crustaceans) grow INSIDE deep water sharks. Some pretty hardcore piercings...

Feeling lucky to have seen Ningaloo in its prime. Devastated that my children will never have that chance.

#NingalooReef "annual surveys of the northern section of the reef in May found up to 90 per cent of coral had been bleached down to 20 metres depth", the "lowest cover of live coral" observed since 2007 "up to 50 per cent of the examined coral was dead in May" but "more would be dead now"

A result that is not surprising to any of us who have worked on the reef in the past year. The Great Barrier Reef is officially in a worse state than it has ever been. www.bbc.com/news/article...

Every single time I hear people challenge commercial fisheries, my response is 'recreational fisheries are often worse, except there's almost no management or policing of it'

This but any kind of science, fieldwork, paper, presentation...

Whenever I (or other shark conservation experts) say "Ocean Ramsey does not raise awareness, she says very wrong things about threats to sharks and their policy solutions," some people feel the need to say "but she taught me something" ...and what they say is always a very wrong thing!

This is your regularly-scheduled reminder that another way of saying “near the beach” is “in the water, where sharks are supposed to be.”

Cutting teeth probably let smaller sharks get higher in the food web than those with grasping teeth. Awesome stable isotope study led by fabulous PhD graduate Sabrina Riveron! @griffith.edu.au onlinelibrary.wiley.com/doi/10.1002/...

So these are basically land shark insects eh? Neat

Sam once again proving he's the BAMF

It's thrilling to see an angelshark swim past a camera in Cardigan Bay, Wales. First sighting in years! As I wrote in What the Wild Sea Can Be, angelsharks are critically endangered but they are certainly not gone. There's so much to fight for in our ocean 💙🌊🦑🦈 www.theguardian.com/environment/...

Fantastic progress. This is a huge first step to getting to grips that shark nets are ineffective and a waste of taxpayer's money. www.theguardian.com/environment/...

Do Sharks Really ‘Play Dead’? The Complicated Truth About Tonic Immobility. www.forbes.com/sites/meliss... New research suggests tonic immobility in sharks might be a leftover behavior with no clear modern-day function, lost by some species but not others.

While North America has been distracted by #sharkweek there has been a major algal bloom in the waters off South Australia and thousands of sharks, rays and many other types of marine life washing up dead on beaches. /1 www.inaturalist.org/projects/sa-...

One of the most common science myths is that we need 10k steps a day...a number originating from a Japanese ad. In general, the more steps the better, right? However, several studies now identify inflection points around 7k as significantly reducing many health risks, from heart to dementia.

Has a marine park been placed where lots of fishing used to occur? If not (and this is where most MPAs sit) then it isn't going to be an effective conservation tool.

Friends, if you want to learn about shark ecology and biology and how scientists study these, I am teaching an online course through Center for Wildlife Studies! You can take it for graduate course credit, for CPE credit, or just to learn! There’s also an optional 3-day field research experience!

Brushturkeys are epic animals. When they decide to dig a nest, nothing stops them. At @griffith.edu.au on the Gold Coast, they've had to put signs up for vehicles because there's no way to stop it from doing its thing!

In the last week I've had papers accepted, rejected, & everything in between. I'm equally proud of the rejected ones (usually about fit and a good dose of journal snobbery) as I am the accepted ones. The key is that U have 2 keep at it - refining, revising, improving, and sharing. Don't give up!

"Boys clubs" are one of the worst things in science, as is the way a lot of women and minorities are treated. Science is better when we're all working together.

For those internationals who follow me, there's a state-sized death zone in the oceans south of Adelaide (South Australia) caused by an algae bloom like we've never seen. Everything in that area is basically dead, including sharks and rays, fishes, crabs... everything. It's unprecedented. 🧪🦑

Effects of marine heatwave driving ‘foreseeable’ SA algal bloom could rival black summer fires, scientists warn

Apparently you can’t tell jokes on Bluesky, so here’s my favorite shark joke. What do you call a shark with no eye? A shrk! Wait No Sorry that joke only works with fish
