From seahorses to sharks, 3,000+ fish species have been caught in bottom trawls, including those most at risk. Our new global inventory shows that what’s recorded is only a glimpse of the true toll of bottom trawling. projectseahorse.org/bottom-trawling-catches-...

Our #FishOfTheWeek this week is… the Great Hammerhead (Sphyrna mokarran) 🐟

Energetic benefits of prey choice for a shark-eating shark - Oecologia Optimal foraging theory has been used to understand the foraging choices of animals but is rarely applied to large predatory fishes due to difficulties measuring their behavior in the wild. Great hamm...

Energetics suggest Great Hammerhead Sharks only need to eat ~0.7% of their body weight per day of other sharks to survive. Means a ~250 kg big one would only need to eat one ~50 kg shark every three weeks! Good reason to be shark and ray-eating specialists.

What Ocean Ramsey does is not shark science or conservation: some brief thoughts on “the Shark Whisperer” documentary Netflix has a new (sarcastic air quotes) “documentary” out about Ocean Ramsey, who longtime readers and followers know is a serial wildlife harasser who also coordinates massive online …

Enough of you asked me about this that I wrote some brief thoughts on Ocean Ramsey's particular brand of pseudoscientific nonsense. I believe this addresses almost all of the frequently asked questions I receive, but as always I am happy to answer serious questions asked in good faith.

Thanks for hosting this! This was fun!

Success! No whale hunting in Iceland at all this year - Whale and Dolphin Conservation

I saw on LinkedIn that there is officially no whaling in Iceland this summer! The last remaining minke whaler is selling there boat!

Less than 3% of the ocean being protected is a crazy stat!

David Attenborough has such a unique perspective, having lived for so long I love it.

Overfishing drives over one-third of all sharks and rays toward a global extinction crisis The IUCN Red List of Threatened Species is increasingly used to reveal the health of ocean biodiversity. Dulvy et al. assess 1,199 chondrichthyans and demonstrate the need for fishing limits on target...

Sharks out living dinosaurs but might not out living over fishing is so sad

Conservation and population research is so important. I just read a paper that said three chondrichthyan species are now critically endangered possibly extinct due to over fishing! #OceanChat

"The idea of bulldozing through a pristine rainforest causes outrage, yet we do the equivalent underwater thousands of times every day" Attenborough's before/after footage of dredging and trawling operations is powerful #OceanChat

I’m going to be honest I don’t think I’ve ever seen a video from below of these bottom trawlers.

For the experts in the chat Is there a better way we can do this so it doesn’t hurt the sediment up?

Mine is out cold no amount of wows could wake her 😂

I'll never get tired of watching bait balls. #OceanChat

I just took a class looking into symbiosis and it was so interesting! I’ve taken microbiology in my undergraduate but to apply it to other organisms was a really cool perspective!

Coral reefs so cool! I love seeing all the different communities and diversity in coral reefs! They help a lot with camouflaging some reef sharks helping the juveniles shelter from predators! They are so valuable!

New paper! Electric rays can use their electric discharge to repel large sharks. Here a white shark carrying a camera approaches a Pacific electric ray. Something caused it to sprint 20 m shallower!

MBL scientists use skates and their embryos to study skeletal development. By shining a light through egg cases, scientists can watch the entire maturation process.
