The World of Sharks podcast returns with the launch of Season 8. On this episode, we explore the world of shark movement and behavioural ecology with expert Dr @sammy-shark.bsky.social, research scientist at the @stanfordhopkins.bsky.social. Listen here: saveourseas.com/worldofshark...
Excited to be co-hosting my first session at my favourite conference 🦈 Let us know if you need more details
🦈 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: Our long-term imagery from Central CA white shark sites reveals extensive injuries & scars. What causes these wounds? We developed a classification system to categorize injury patterns. 📖 www.frontiersin.org/journals/mar...
🚨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
📽️🦈Dive deep into the Monterey Bay White Shark Project 🦈📽️ Our new video showcases the team and technologies being used to study large predators and their prey in the Monterey Bay National Marine Sanctuary www.youtube.com/watch?v=zqSd...

Feel in love with penguins on a visit to Isla Pingüino today. Very jealous of all you penguin researchers out there!

I always love hearing about @emilylester.bsky.social's work using life-size shark models to look at risk effect behaviours. This was the first paper from her PhD on the topic nsojournals.onlinelibrary.wiley.com/doi/full/10....

I love this paper by @sammy-shark.bsky.social et al. Shark vertical movements are fascinating to me, and this paper makes the most of a cool high resolution dataset from an ecophysiology perspective. 🦑 🧪 🦈 www.nature.com/articles/s41...

Hi Bluesky! I'm Sammy and according to my research to date, I'm a big fan of movement and sharks. What scholargoggler.com doesn't tell you is that I also love to surf, hike, drink wine with friends, and generally be outside.
