Systematic assessment of the increasing presence of white sharks in Atlantic Canadian waters 🦑🧪🐟🦈 www.int-res.com/abstracts/me...

🦈 Heading to Sharks International 2026? Consider applying to our session: 🎯 Quantifying the Chase: New Frontiers in Predator–Prey Dynamics We’re exploring tools, techniques & cross-disciplinary insights. 🌐 si2026.org @sharks-int.bsky.social #SharksInternational2026 #SharkScience #MarineEcology

🦈 #shark New research from Dr. Viktoriia Kamska findd the #dermaldenticles of a #blueshark contain closely spaced scales made of guanine. Pressure changes can alter the spacing of these guanine scales within a cell, and that can subtly shift the colors of skin www.eurekalert.org/news-release...

Por si las coloraciones y patrones que habían eran pocas! ;)

What Basking Sharks Tell Us About The Climate Crisis

Ocean warming increases residency at summering grounds for migrating bull sharks (Carcharhinus leucas) 🦑🌎🐟🦈 www.sciencedirect.com/science/arti...

New paper lead by @etspencer.bsky.social We use biologging to understand why great hammerheads may specialize on large prey like other sharks. If they hunt blacktips off south Florida then they probably only have to catch a shark once per month link.springer.com/journal/442

Exciting news: our new study just published! We looked at how Important Shark and Ray Areas (ISRAs) can also support the identification of Key Biodiversity Areas (KBAs). Our findings? 1 in 5 ISRAs already qualify as KBAs.

How ‘Jaws’ Sank Shark Conservation Before It Began www.forbes.com/sites/meliss... Shark numbers are down more than 70% since the 1970s, and the economic and ecological fallout is now impossible to ignore.

🦤🌐🧪 White sharks are on the rise in Atlantic Canadian waters! Our new study reveals an increase in their presence since 2019, with migration probabilities up to 3.7x higher and their seasonal stay extending by over 20 days bit.ly/meps_761_145

📣 Just out! @FAO.org has released the most detailed report ever on the state of marine fish stocks! The data shows that some of the world’s fisheries are recovering thanks to effective, science-based management. 👉 bit.ly/4l0LV28 #UNOC3 #BlueTransformation

Mientras viajaba en tren ha saltado la noticia de que Colossal, la compañía del señor que vio Jurassic Park y dijo "esto es un plan cojonudo" la ha vuelto a liar. Así que vamos a hablar de ello.

I’m excited to share that the final chapter of my dissertation has been published. We used multiple applications of network analysis to acoustic telemetry data to explore seasonal movements of great hammerhead sharks tagged in the FL Keys. 🧪🦈 doi.org/10.1111/jfb.70039

Sobrepesca y cambio climático, el cóctel que amenaza a algunas poblaciones de tiburones y rayas en el Mediterráneo. El @informemarbalear.bsky.social indica que el quelvacho (Centrophorus uyato) se encuentra en peligro de extinción en aguas de Mallorca. @marillesfoundation.bsky.social #SARKO

1/2 Some fishes hide behind sharks to surprise their prey. It has been documented in the Mediterranean (Lampione, Italy), they are blue runners (Caranx crysos) hiding behind sandbar shark (C. plumbeus). (paper) esajournals.onlinelibrary.wiley.com/doi/10.1002/...

🆘 According to the IUCN Red List, sawfishes are among the most threatened marine vertebrates globally, with populations declining by more than 90% due to overexploitation and habitat loss. Without urgent conservation action, they face extinction.

Our bias towards charismatic species leaves 'ugly' animals behind in conservation efforts. But should looks determine which species we protect?🐡 🎧 @ipbes.net podcast ep feat. the world's ugliest animal "Mr. Blobby": https://www.podbean.com/ew/pb-j54ym-17ac1d1
