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.
Proud to share our white shark team's newest project film 🦈 Months of collaboration, research, and ocean time distilled into one compelling story www.youtube.com/watch?v=eJdf...

🚨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!

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. 🦑 🧪 🦈
