A week from now I will be traveling across the world to Colombo, Sri Lanka for #SharksInternational2026 ! If you are interested in shark life histories and what drives population growth rates, come see my presentation @sharks-int.bsky.social #SI2026

I’m headed to Sri Lanka in 1 week for #SharksInternational2026! Excited to see everyone’s work! If you’re interested in species’ MPA coverage, international reporting of no-take areas, or a new tool for exploring coverage for your study species/region, come check out my talk @sharks-int.bsky.social

If you: - are part of the ray fan club, - wonder why I post from a museum collection every few months, - are interested in the connections between morphology, ecology, and biodiversity, And are going to #SharksInternational2026, check out my talk on Monday, 4 May at 12:40! @sharks-int.bsky.social

Happy International Day of Women and Girls in Science! Grateful for the mentors, collaborators, and friends who make science stronger every day. #WomeninSTEM @rachhson.bsky.social @sfubiosciences.bsky.social @sfuscience.bsky.social

New paper out today in @natrevbiodiv.nature.com by the #GlobalSharkTrends team: Bending back the curve of shark & ray biodiversity loss; Read the paper here: rdcu.be/eZ9n9 @sfu.ca @sfubiosciences.bsky.social @earth2ocean.bsky.social

@rachhson.bsky.social at #EEA2025 Trait-based ecology uses biological features to predict an animal’s ecology. Sharks with certain fin shapes shapes have bigger gillslits, faster swimming speeds. Can be measured from museum specimens- Rachel spent months in museums all over Europe.

Successfully wrapped up our third and final week measuring rays in Europe at the Natural History Museum in London 🇬🇧 huge thank you to @nhm-london.bsky.social for hosting, and thank you @amandasodysseys.bsky.social and @nickdulvy.bsky.social for helping me measure 309 rays representing 123 species!

A bit late, but we’ve (@rachhson.bsky.social @nickdulvy.bsky.social) wrapped up our second week measuring rays across Europe. Goodbye Paris and thank you to the teams at @mnhn.fr who made it possible! 🇫🇷✨on to London 🇬🇧! @earth2ocean.bsky.social #labwork #mobulamonday #scienceinaction #womeninstem

Day 1 in Museum du Naturalle Histoire du Paris #MetabolicMorphology #SharksNearMe #DulvyLabGoesOutside #LoveMuseums #RaysNeedLoveToo #Paris #Brusselles #HamburgNaturalHistoryMuseum #NaturalHistoryMuseumDeParis

Just wrapped up a great week measuring rays at the Museum der Natur Zoologie @leibnizlib.bsky.social in Hamburg 🇩🇪 for @rachhson.bsky.social’s PhD, over 135 specimens measured! 🦈✨ Next stop: Paris 🇫🇷, as our whirlwind tour through Europe’s ray collections continues @nickdulvy.bsky.social

🚀 Sharks International 2026 website is LIVE! We’re thrilled to officially announce the launch of our brand new website: si2026.org This is your go-to hub for everything related to Sharks International 2026. Follow our page for the latest updates on #SI2026!

A spectacle to behold, in the shallows, hugging this island, we see broad cowtail rays and mangrove whiprays - and looking with a close eye, few juvenile blacktip reef sharks weave between the rays. Footage by Sebastian Staines. #saveourseasfoundation #sharksandrays #conservation #videography

Always glad to celebrate my sisters in STEM! Happy International Day of Women & Girls in Science 👩‍🔬🦈- Grateful for the incredible women who have supported me and for all the amazing women scientists blazing trails and making a difference every day. #WomenInScience #WomenInSTEM @rachhson.bsky.social

Wow, hi new followers 👋! I'm Rachel, a PhD Candidate with @nickdulvy.bsky.social in the @earth2ocean.bsky.social group. My research explores the ecofunctional morphology of sharks and rays, so I'm working on connecting what species look like to the role they play in their environment.

OPEN CALL for Sharks International 2026 proposals for keynote speakers, themed sessions and panels, workshops, and side events 📢 🦈 Please submit proposals via: forms.gle/9EiKJVncMoa7... Deadline: 15th March 2025

New summary of 2 massive recent publications documenting the status and trends of sharks, rays, and chimaeras 🧪🦈🌎 @mongabay.bsky.social news.mongabay.com/2025/01/new-...

New #GlobalSharkTrends study published in @science.org reveals #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/GlobalSharkTrends 🧵1/20

Ok, this one I *do* want your help with. Making a starter pack of shark and ray scientists and conservationists. There are a lot of folks I missed, help me fill this out. go.bsky.app/Q1x1gJB 🧪🌎🦑🦈🐠

Congrats @nickdulvy.bsky.social ! www.sfu.ca/sfunews/stor... 🦑🌎🧪🐠

If you want to present at the upcoming 7th International Marine Conservation Congress, today is the last day to submit an abstract! 🧪🦑🌎

👾It’s finally here! 👾The community science mobile game that we’ve been working on with our fronds at FathomVerse and @mbarinews.bsky.social is now available for FREE in the Google Play and Apple App stores! Download it here: www.fathomverse.game

What a great weekend for E2O! The Palen & Côté labs made waves at #PEEC2024 at the Bamfield Marine Sciences Centre. Meanwhile, the Dulvy lab shared insights at #NEPSSVI at the Seattle Aquarium. From local invasive species to global protected areas, we are passionate about sharing our science! 🌊🦈

Deepwater sharks and rays make up half the global shark and ray diversity but have been largely left in the dark for shark and ray conservation. 🦑🌍🐟   #SharksintheDark #GlobalSharkTrend bit.ly/SharksInTheD...

Happy #International_Womens_Day to these amazing scientists who provide me with *constant* support in the lab @rachhson.bsky.social @hannahvwatkins.bsky.social

Super excited to welcome new PhD student Rachel Aitchison to the Earth to Ocean Research group at Simon Fraser University. She's working on "Metabolic morphology of rays"
