Baby sharks, belly buttons, and the science of invincibility

Some newborn sharks have a belly button... but it heals! What can this teach us about injury healing, especially w/ ocean warming? New study by @shamildebaere.bsky.social & #physioshark team published in J. Fish Bio.

Marine wildlife fleeing to poles due to global heating as Australian oceans face ‘uncharted’ future From 2040 onwards the average year for marine ecosystems is likely to be more extreme than the worst years experienced up until 2015, researchers say

Marine wildlife fleeing to poles due to global heating as Australian oceans face ‘uncharted’ future. The rules that we’ve been relying on for ocean protection and conservation… they’re going to have to evolve.

Fossil fuel lobbyists outnumber all Cop30 delegations except Brazil, report says One in every 25 participants at 2025 UN climate summit is a fossil fuel lobbyist, according to Kick Big Polluters Out

At COP30 numbers are jaw-dropping: 1 in 25 participants is a fossil-fuel lobbyist. If change is going to come from within, then this isn’t a cameo, it’s control. We need institutional integrity & transparency - not just token seats at the table. www.theguardian.com/environment/...

“The National Marine Fisheries Service announced today that it will form a federal task force to curb Pacific humpback whale entanglements in fishing gear. Dozens of humpbacks are entangled off the Pacific Coast every year.”

Getting the EPBC Act right | Biodiversity Council Australia Our factsheet outlines the strengths, weaknesses, and recommended improvements to the Australian Government’s proposed environmental law reforms.

Australia is reshaping its national environment laws, but EPBC Act reforms still leave big gaps. Weak standards, political exemptions, & no accountability for climate impacts = risks for nature. Strong, enforceable protections matter - especially now. biodiversitycouncil.org.au/resources/ge...

Juvenile humpback whale dies off NSW coast while entangled in shark net It is the first whale to have died out of 15 entangled in shark nets on Australia’s east coast so far this year

Heartbreaking loss: juvenile humpback whale (~8m) entangled & drowned in shark net off NSW coast. Shark nets don’t necessarily do what we assume -- protect beach-goers -- and pose serious risks to sharks, whales, dolphins, turtles, and other non-target animals.

But dozens of Australian scientists, including some of the country’s top climate researchers, wrote Albanese this week expressing dismay at the target, imploring the government “to go further”.

Newborn sharks swim like ‘ninjas’ to avoid predator attacks New research shows that baby blacktip reef sharks use warm waters to boost their escape performance from adult sharks, barracudas and other predators.

Newborn reef sharks are ninja swimmers! 🥷🦈⚡️ Our latest study shows pups can dodge predators in under 20ms. A reminder of how amazing—and vulnerable—shark nursery habitats are. Read more via @jcuofficial.bsky.social : www.jcu.edu.au/news/release...

Congratulations! Well deserved!

Dream of breathing underwater inspired fish physiology career A gift of snorkelling gear and trip to Florida was all it took to hook 8-year-old Jodie Rummer, now renowned fish physiologist, into marine science.

Feeling incredibly proud to be featured in Cosmos Magazine in a piece by Dr Richard Musgrove on my journey in fish physiology, climate change, coral reefs, & sharks. Thanks to all the colleagues/students who make this work possible. 🌏🦈🪸

The Great Barrier Reef is a global icon & national treasure, but it's also a frontline casualty of climate change. What happens to the Reef is a warning signal for marine ecosystems globally. We still have time — but only if we act now.
