From sixgills to baskings! Our new #maximus_SHARK project is up and running, and we're visiting the Catalan fishing guilds to start a new collaboration with their fishermen. Together, we'll try to broaden the ecological knowledge of this species in the NW Mediterranean. @manelgazo.bsky.social
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!

New maps reveal the scale of #saiga migrations across #Kazakhstan and the threats they face.
They highlight key migration routes and show how roads, railways and infrastructure can fragment habitat and disrupt movements.

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 👇🏻🦈
The latest #FAO #SoMFi report shows we're steadily getting to an overall more sustainable framework of #resource exploitation. Room for improvement (e.g 28% women workforce, some important fish stocks yet to reach their MSy) but results tell us we're on the right track.
Killer whales and dolphins have been recorded working together to hunt salmon :)

📊 Over 80% of the specimens had ingested microplastics — mostly PET and cellophane fibres, the kind found in countless everyday products.
Even more than in sharks from other Mediterranean areas like the Tyrrhenian, Ligurian or Balearic seas. Why?
