We found that the whip-tail in pelagic rays restores stability during gliding locomotion, acting as a key passive stabilizer.

🌊These cases may then be washed ashore, recording these can help us map areas that are important for the species which lay them!

Don’t forget to record your sightings on our website or the iRecord app!

New Paper!🦈🚨

I’m so excited to share this! We used underwater cameras to study sharks, skates and rays in Scotland. From 682 hours of footage we recorded 6 species, including the Critically Endangered flapper skate. Check out the paper below!

Animal tracking with particle algorithms informs protected area design Particle algorithms strengthen the value of acoustic telemetry for conservation.

Interesting read this morning - new paper on #elasmobranchs and #acoustictelemetry led by Ed Lavender - integrating acoustic telemetry, archival data and particle algorithms to investigate space use within + beyond an MPA, well worth a read! www.science.org/doi/10.1126/...

Recent declaration of the #Cardigan-Caernarfon Bay Important Shark and Ray Area by the @iucnshark.bsky.social highlights wider regional significance for #elasmobranchs and the need for more #shark research.

Moments like this remind us why we spend so much time out here: the thrill of discovery, contributing to science, and the chance to see South Africa’s lesser-known species up close.🇿🇦

Assuming not a hoax, here’s a small unidentified #shark caught by an angler on a S coast beach in U.K that doesn’t match any local/regional species. They’re seeking an id - any ideas? @seatrustwales.bsky.social @iucnshark.bsky.social #Elasmobranchs

One of the joys of studying museum collections: discovering tiny treasures like this little round stingray!

These species of chimera typically inhabit depths of up to 374m, so when the currents and ocean conditions are on our side, we get the rare opportunity to find these alien looking egg cases!

Hi! I'm a #marinebiologist researching data poor & rare #sharks & #rays. I'm running away from the bird app before it implodes 🙃

If I'm not posting about #elasmobranchs I'm usually spreading my love of #Irish by sharing marine themed posts as Gaeilge w/ #OceanAsGaeilge. It's fun - stick around! (:

I encountered several Marbled Torpedo (electric) rays during my #openwaterswimming session this morning. #Gibraltar #marinelife #elasmobranchs

The $1-Billion Shark Trade: Can Conservation Keep Up? Shark and ray products now rival the fin trade in value, but with many species threatened, conservation requires immediate, country-specific action. A comprehensive report outlines solutions.

“This report is a call to action………... It is the only way these species will survive and continue to thrive in aquatic ecosystems.”
