Scientists have developed a scalable “holdfast-graft” method to reseed Tasmania’s lost giant kelp forests. By binding hatchery kelp to other seaweed stubs, divers achieved 40× higher survival. Within a year, the grafted kelp began reproducing—kick-starting self-sustaining forests. #GreatSouthernReef

Time to vote for the Australian Bird of the Year! I’m backing the Tawny Frogmouth. It looks like a stick, acts like a log, and still manages to be ridiculously charming. Could this be its year?Vote here: www.theguardian.com/environment/... #AussieBirdOfTheYear #TawnyFrogmouth

Study spotlights West Papua habitat as whale sharks face increased pressures

Bleaching on both the Great Barrier Reef and Ningaloo is a warning we can’t ignore. The window to protect our coral reefs is closing fast and we must act now to limit warming and safeguard these iconic ecosystems. 🔗 www.bbc.com/news/article... #CoralBleaching #MarineScience

🦈 Heading to Sharks International 2026? Consider applying to our session: 🎯 Quantifying the Chase: New Frontiers in Predator–Prey Dynamics We’re exploring tools, techniques & cross-disciplinary insights. 🌐 si2026.org @sharks-int.bsky.social #SharksInternational2026 #SharkScience #MarineEcology

🚨New paper! 🌍🦈😇 What do seafloor patterns reveal about fish, fear & food webs? Tracking reef halos at Ningaloo Reef, we found they shrink in summer but grow in winter, correlated with seasonal temp and upwelling. Single snapshots don't tell the full story. Context matters! 📖 rdcu.be/ewTI1

Port Jackson season is kicking off in Sydney, and I couldn’t be more excited! Ready to brave some chilly waters for some face time with these curious little sharks 🦈❄️

2024 saw a global bleaching event, but bleaching doesn't always mean corals die. Using drones, we found the 2024 bleaching event killed over 90% of shallow corals at Lizard Island. 🧪🦑🧵 We have to act now. @griffith.edu.au JCU MQ @geonadir.bsky.social CSIRO link.springer.com/article/10.1...

🐠🦈 Just out: In this paper we ask "How has reef trophic structure changed since humans started removing predatory fishes from Caribbean coral reefs?". www.pnas.org/doi/10.1073/... Illustrations @cookedillustrations.com

📣 We are excited to announce the opening of submissions for two prestigious #ECR awards: 🐟🏅 ASFB Early Career Excellence Award www.asfb.org.au/awards/asfb-... 🐟🏅 Early Career International Travel Scholarship www.asfb.org.au/awards/early... 🚨 Applications close 30 June #fish #biology #science

In 1907, Kumataro Ito was hired to illustrate the nudibranchs collected on the Steamer Albatross' Philippine Expedition. 490,000 specimens were collected & stored in ethanol. They've lost their beautiful colors, but the illustrations are still stunning: blog.biodiversitylibrary.org/2017/08/arti... 🧪

Yet again we are seeing "unprecedented" marine heatwaves in 2025. buff.ly/mnEcYcV What will we see in 2025 & beyond? @dansmale1.bsky.social comments, “If this continues through the summer we would expect to see widespread biological impacts. This is a significant warming event." buff.ly/U6iBTBN

Last call ⏳🚨 If you have any elasmobranch and killer whale interaction records we want to hear about it! Please reach our team with the email below, would love to include them in our global review!

🚨NEW PAPER🚨 We used acoustic telemetry to track 355 white sharks over a 15 year period in California, describing differences in seasonal trends among demographic groups. DM if you need a copy, and huge thanks to all collaborators - it took a village! www.publish.csiro.au/WR/WR24136

My first first-author paper (my master's work) is finally out in @animalecology.bsky.social ! We found that the recovery of reef shark populations invoked anti-predator behaviours in mesopredatory reef fishes on Ashmore Reef in Western Australia🦈🐟. doi.org/10.1111/1365...

In 2019, we showed that tiny, bottom-dwelling fish can fuel coral reef energy fluxes. In our new paper, we reveal a dramatic dichotomy in their functional role across coral reef habitats separated by a few 100 meters. esajournals.onlinelibrary.wiley.com/doi/full/10.... @esajournals.bsky.social

Wrapped up this week with a very cool encounter. Behold, the majestic Glaucus atlanticus! This pelagic nudibranch inhabits the open oceans where it feeds on venomous creatures, like the man o' war. This beauty has been on my bucketlist for a long time. Thanks @joshuacinner.bsky.social for the spot!

Oh hey. Hey you. Keep swimming. You're doing great. Bluestripe Snapper (Lutjanus kasmira), South Ari Atoll, Maldives

My colleagues at NOAA fear for their jobs. Their satellite observation today of accumulating heat stress (already above mortality thresholds) on the northern Great Barrier Reef: Yet again a deadly mass coral bleaching event is underway. Without NOAA, climate & reef scientists will be blind.

Love bites? Pre-copulatory behaviours of whale sharks (Rhincodon typus) at Ningaloo Reef, Western Australia 🦑🧪🐟🦈 www.frontiersin.org/journals/mar...

Time for your annual reminder that it’s Tasmanian devil dispersal season! This means young devils out finding their way in the world are particularly vulnerable, & often drawn towards roads for easy passage & food. So watch your speed on Tassie roads this season & keep an eye out 👀

Continuing with the angelfish theme, here is another one of my favorites, the Majestic Angelfish (Pomacanthus navarchus). It's found in the western Pacific, mostly within the Coral Triangle, and it's always uncommon, so I photograph it every time I see it! #ichthyology

🚨🦈 New shark science! 🦈🚨 We observed a sexually mature male whale shark biting the caudal fin of a (likely juvenile) female whale shark. Biting is a pre-copulatory behaviour for many shark species, so this observation provides possible insights into the mating behaviours of this endangered species 🌊

🚨 OUT TODAY! 🚨 New paper in @science.org shows the decline of global shark and ray populations, with declines of specific ecological groups more severe than others 🦈 🔗 Article and press release bit.ly/GlobalSharkTrends 🧵Full thread below ⬇️

We have a starter pack for people studying predator-prey interactions, dynamics, consequences, ect. Please reply or DM if you want to be added. Also keep an eye out for the Gordon Research Conference on Predator-Prey interactions that will be held in early 2026 in Italy. go.bsky.app/PACvzLU

Woke up in Tasmania and found a platypus on my coffee stroll. I rate this morning a solid 12/10 #wildoz

Terrible news today: This year, one-third of coral cover has been destroyed in two northern sections of the Great Barrier reef due to anthropogenic heating. Results for the southern sections (which were even hotter) have not been officially released. www.aims.gov.au/information-...

Hello BlueSky. I'm Emily- a marine ecologist with an interest in predator-prey interactions, ecosystem function, and I really like sharks. Generally, I try to spend as much time as possible underwater. I recently moved to Sydney and am enjoying the diving scene (see video). Excited to chat!
