Our new research paper is out. We found microplastic ingestion by the blackmouth catshark (Galeus melastomus) in the canyoned continental margins of the Gulf of Lion was high, more than in other parts of the Mediterranean and was influenced by the role of those canyoned margins. Full thread 👇🏻🦈

Cutting teeth probably let smaller sharks get higher in the food web than those with grasping teeth. Awesome stable isotope study led by fabulous PhD graduate Sabrina Riveron! @griffith.edu.au onlinelibrary.wiley.com/doi/10.1002/...

We’ve recently finished our #Bocadolça project, the main aim of which was to determine presence and seasonality of the bluntnose sixgill shark (Hexanchus griseus) in the deep waters off Catalonia (NW Mediterranean). @manelgazo.bsky.social (1/3)

Breaking barriers: Transoceanic movement by a bull shark 🌊 🧪 🦑 doi.org/10.1002/ecy....

Yesterday, an unfortunate 7m-long basking shark (Cetorhinus maximus) was caught by trammel nets in Port de la Selva (NE Spain), close to shore. Sightings of this species start to be more frequent along the Catalan Coast at this time of the year, likely driven by ++[phytoplankton] in the region.

New study shows that #SouthernOcean #warming plays a greater role than #Arctic Ocean warming in shifting tropical #rainfall in a future climate, increasing rainfall in #Brazil and enhancing #drought risk in the #Sahel. www.nature.com/articles/s41...

Cognitive perception of circulating oxygen in seals is the reason they don’t drown 🦑🌎🧪🦭 www.science.org/doi/10.1126/...

Important paper shows white shark reproductive population in eastern Australia might be as few as 500 adults... challenges the idea that shark populations are "exploding" onlinelibrary.wiley.com/doi/pdf/10.1...

New research by Colloca et al. found that the average contribution of elasmobranchs to the total annual landings of EU fisheries operating in the Mediterranean Sea from 2013 to 2022 was, in economic value... 0.60%. link.springer.com/article/10.1...

Lots to learn from Rwanda www.telegraph.co.uk/global-healt...

To set up a protocol for the release of accidentally captured bluntnose sixgill sharks 🦈…. the key is to listen and learn from the experts. A huge thank you for your time and knowledge, skippers! Projecte #Bocadolça @marinemegafauna.bsky.social @irbio-ub.bsky.social @ub.edu @ignasinr14.bsky.social

The wave of rising shark & ray extinction risk #GlobalSharkTrends 👉 started in rivers, estuaries, nearshore coastal waters 👉 before rapidly expanding out across the oceans. Lower risk only in harder-to-fish nearshore habitats, ie, 👉 Kelp/algal reefs 👉 Rocky reefs, & 👉 Deepsea 🧵10/20

Hello there, folks. Looks like Bluesky is here to get us all back on the right track. Well then, I’m up for that too. I’ll be mostly posting about shark research and conservation and, quite frequently, about these guys (Hexanchus griseus) in the Mediterranean. See you around!
