As a lesser known group, we struggle to fill our presenter schedule, and we cannot pay people much to our dismay. We would love to have Elasmo Week this year, but we do need a few more presenters. If you or someone you know wants to share or teach anything cool...

First day looking at rays at Cal Academy with the Dulvy lab! #dulvylabgoesoutside Earth2Ocean Science SFU Biological Sciences

#wingheadwednesday Did you know the Endangered winghead’s head can be up to half the size of its body length? #sharksnearme #dulvylabgoesoutside SFU Biological Sciences Nicholas Dulvy

#ThrowbackThursday We use museum specimens from the Gulf of Thailand give us some insight into the diversity of life in the area 50+ years ago, a diversity we don’t see today, these big rhinorays and the winghead shark are no longer found in the area #lostsharks #WorldOceanDay

Smile it's #flatsharkfriday ! Here all week California Academy of Sciences w. Rachel Amanda Arnold 🦈✨ measuring gill and tail shape to develop trait-based approach to #LifeHistories #FunctionalEcology #sharkscience

Happy #FlatSharkFriday! I got to meet one of my thesis specimens, the bareback guitarfish (Rhinobatos nudidorsalis), and #reunited with LostSharkGuy California Academy of Sciences

Just another #MakoMonday… You might know that the Endangered Shortfin Mako is the fastest shark around, but did you know that they also have one of the largest brain-to-body ratios? #sharksnearme

🚨 New Paper out 🚨 #GuitarfishArePlucked now published in Marine Policy showing high volume in international trade and LESS THAN HALF of ideal management in place globally: bit.ly/GuitarfishPluc… #FisheriesManagement #SharkScience #CITES #Overfishing

The next area of focus for the Important Shark and Ray Areas Project is the Western Indian Ocean! Please submit preliminary areas of interest by August 11. More information here: drive.google.com/drive/folders/… Please share with interested colleagues!

My first paper as first author is out now, published #OpenAccess ! Special thanks to all my coauthors that helped make this a reality. Check it out here: royalsocietypublishing.org/doi/epdf/10.10… Nicholas Dulvy Wade VanderWright 🌊🦈 @DrLucyHarding David Jacoby Nicholas Payne

Happy International Ghost Shark Day! Our team and partners work to understand and protect sharks and their relatives, including the chimaeras ("ghost sharks") Learn more about ghost shark conservation: onlinelibrary.wiley.com/doi/full/10.11… Learn more about us: iucnssg.org/mission-vision…

Hot off the press in time for #FlatSharkFriday - my master's thesis with LostSharkGuy on guitarfish is published! Huge thank you to Save Our Seas for supporting the work, the wedgefish & guitarfish symposium, and the special issue in ESR!!

Happy #International_Womens_Day to these amazing scientists who provide me with *constant* support in the lab

🚨NEW PAPER ALERT🚨 Out now #OA in Royal Society Open Science: "Ecological lifestyle and gill slit height across sharks" 🔗 royalsocietypublishing.org/doi/10.1098/rs… #SharkScience #OpenAccess Nicholas Dulvy Jenny Bigman Anthony Iliou 🧵 below

Rachel getting ready for her 2nd round of measuring rays! This time at UBC’s Beaty Biodiversity Museum 🐳 - looking forward to pulling these little guys out in July #dulvylabgoesoutside #raysnearme #sharksnearme

#raysnearme Some metabolic morphology with ray burritos happening down Beaty Biodiversity Museum 🐳 with Earth2Ocean Science crew #MuseumMonday #SharkScience

Rachel was stoked to find one of her MSc species Austin's Guitarfish Rhinobatos austini SAIAB here in Makhanda, South Africa

Okay so today we got to see the BIG tanks SAIAB and found the Reef Manta Ray Mobula alfredi; the #hottake was that this was just gills-on-fins... look at the length of those gill slits... #MetabolicMorphology

Phew! after 2 weeks working SAIAB its a wrap. We measured 25+ #MetabolicMorphology traits from 43 sharks & 240 ray specimens, spanning 60 species, from endemic catsharks, skates & electric rays to pelagic and deepsea sharks. The Coelocanth was discovered in East London by

New #GlobalSharkTrends study published in Science Magazine reveals that #overfishing has more than halved shark & ray populations over the past 50-years causing widespread erosion of ecological function and exceptionally high extinction risk 👉🏽Full article bit.ly/GlobalSharkTre…
