Behavioral Evidence of Predator–Predator Commensalism: Cobia Track and Feed on Prey Disturbed by Southern Stingrays We documented a novel predator–predator commensal foraging interaction between cobia (Rachycentron canadum) and a southern stingray (Hypanus americanus) in a shallow coastal habitat of Biscayne Bay, ...

@juliasaltzman.bsky.social was in the right place at the right time to record and generate an ethogram of a stingray-cobia pair, an interaction fishers have relied on to find and sight-fish for cobia!

Who Nose What Flows: Shark Narial Denticle Morphology and Hydrodynamic Implications Synopsis. Dermal denticles (scales) are important in influencing the movement of water around a shark’s body. To date, most of the research on denticle mor

I finally did it. My first chapter is FINALLY written and out for all to see. If you’ve attended my talks you 100% know what this is about. If you haven’t attended my talks, shark nostrils are more interesting than we thought. Enjoy! academic.oup.com/icb/advance-...

Nursery Resource Use Dynamics in Great Hammerheads (Sphyrna mokarran) Across Ontogeny The ecological trade-offs required by nursery dependence are poorly understood. Using multi-tissue stable isotope analysis, this research provides evidence of constrained resource use in juvenile gre....

Annual GRFP thread, more relevant than ever (# of awards down 50%).

This thread is for students who didn't win the GRFP today. Who are wondering if they belong in science, or scrolling through posts that start "So excited to announce..." with a little spurt of bitterness they aren’t proud of. 1/9

We have a new #sharkscience paper just out on working with batoids, including ethical considerations and guidance regarding the difficult choices field researchers sometimes face. This was a global collaborative with many authors, and is published as #openaccess link.springer.com/article/10.1...

Predicting Sawfish Habitat in a Changing Environment NOAA Fisheries and partners published research that identifies key habitat features of juvenile endangered smalltooth sawfish and predicts where else they could be.

Satellite map of south west Florida showing hotspots of juvenile smalltooth sawfish abundance as small pixels scattered around inshore coastal bays.

Smalltooth sawfish are beautiful, weird, and endangered. With colleagues at @noaa.gov and @coastalelasmos.bsky.social, our 15-year study revealed habitat preferences and hotspots of juvenile sawfish, suggesting key areas to protect around SW Florida as climate changes. Data access was a key hurdle.

Couldn’t miss it! 💙

Awesome job @drcatmac.bsky.social !!
