Research started of with a bang in Israel! First night of sampling with Drs. Leigh Livne Aviad Scheinin was a success! Using an @eimedical EVO III this gravid dusky shark was tagged with @LotekWireless tech to follow her movements and see where she gives birth!
Big day, big year in our lab!!!@BeckahCampbell has passed her Phd comps and has advanced to candidacy! @sharkbrooke passed hers earlier this year- think we are happy? ⬅️ to see! So proud of these two for all their hard work and leadership advancing the labs research.
Linking reproductive state to habitat use and movement is critical to effective management. To do this we connect ultrasound images to reproductive hormones. The female porbeagle in the video was pregnant (gravid) and we are tracking her movements now. Where will she go?
Check out @sharkbrooke grabbing a blood sample from a porbeagle shark in order to evaluate circulating levels of reproductive hormones. We use this information to continue to develop non lethal techniques to study this life history stage in sharks and other fish.
Nothing says Happy Friyeah like a porbeagle release! 13 sharks were double tagged and will collect great habit information for those sharks over the next year. Of particular interest are our 6 pregnant females- we can’t wait to see where they go!
We wrapped up our portion of research with @physioshark this week looking for pregnant blacktip sharks. We’ll be tracking momma sharks to determine habitat use around French Polynesia and where they are giving birth!
We researchers rarely get to see our tagged sharks swimming around collecting data! Check out this pregnant blacktip reef shark affixed with a @lotek Psat. Great video by @rummerjodie and @brooke_anderson1 as part of @physioshark research! Can’t wait see where she gives birth!
Incredible end to a fantastic porbeagle trip! 13 sharks @LotekWireless tagged and we are now tracking 6 @eimedical pregnant sharks for @sharkbrooke dissertation! So happy to see them swim off to give us data! More info to come!
Just finished an amazing 3d of tagging blue, mako, and porbeagle sharks off Cape Cod with excellent team @DrNeilHammer @LauraHopeM @sharkbrooke@NolaSeas. 13 sharks satellite tagged and happily released! Excited to see where they go next 🗺
You think Porbeagle sharks like New England? Check out the movement of 12 sharks fitted with fin mount sat tags! Many of theses tracks represent over two years (and counting) worth of data. Looking forward to putting more tags out on Expedition Porbeagle!
NEW COLLABORATIVE PAPER: Our team, co-led by @DavidCurnick, compiled the first global synthesis of vertical habitat use by elasmobranchs.

Congrats to our @sharkbrooke who was selected as the winner of the Donald R. Nelson award at this years American Elasmobranch Society meeting for her work on porbeagle sharks! Great Job brooke!!!!Kudo’s to her collaborators and mentors!
Excited for two research expeditions in the Caribbean! Hopefully we get to see some shark moms! Using an ultrasound allows us to better understand what habitats are important for shark moms and their babies (Check out the teeth (red ⬅️) on this one) ! ! More to come!!!
Baby porbeagles- otherwise known as “porkchops” so cute! Expedition new England is less than 6 weeks away!! We can’t wait to learn how this little lamnid is using the Gulf of Maine!
Pregnant porbeagle shark update! Check out Watts’ incredible 7 month journey -her most recent locations show her moving inshore to potentially give birth before heading back off shore. These observed movements are the first for this species! So cool!
