Now that I own three centrifuges, various pipettes, and tons of vials I think it is safe to say that my transition from boat captain to shore support is complete! #SawfishResearch

"A new study utilizing historic museum specimens has revealed a drastic decline in the genetic diversity of critically endangered largetooth sawfish. The findings show a sobering picture: globally, genetic diversity has plummeted."

Very sad update on the endangered #sawfish mortality events in early 2024 and 2025 in the Florida Keys. Thank you @CHANGINGSEAS and @SawfishRecovery team member Dr. Dean Grubbs for keeping this important story alive! #EverySawfishMatters

Findings of a significant declining trend in relative abundance of small juveniles and limited numbers of adult females are concerning.

There's still time to come visit our sawfish booth at the Burrowing Owl and Nature Festival!

Thank you @SCWaterkeeper and @tbwaterkeeper for building a coalition to stop the Skyway Cruise Port. Please sign this petition and stand up to protect the waters around Rattlesnake Key (where we caught, tagged, and released three newborn endangered smalltooth sawfish in 2023).

They will highlight potential development impacts to sawfish habitat in the Caloosahatchee River and explain how the public can get involved.

We had all the seasons this week for receiver downloading in Tampa Bay, Terra Ceia Bay, and Manatee River. Felt really bad for the divers on the cold days, but we got some exciting new data for our sawfish, shark, and cownose ray tracking studies!

🚨This is not good for Florida🚨 Staghorn and elkhorn corals are now functionally extinct in the Florida Keys and Dry Tortugas following the historic 2023 marine heat wave.

These toxins affect fish neurologically, causing them to spin and behave erratically. The critically endangered smalltooth sawfish are among the species that have been seen spinning and sawfish mortalities have been documented at unprecedented and alarming levels.
