YouTube video by Elasmopoulo First acoustic telemetry tagging of blue shark (Prionace glauca) in the Ría de Vigo (Galicia, Spain)

#BELAS News❗❗
A new species joins the crew. Yesterday we tagged our first blue shark in the wild! 🦈

That makes it species number 8 in the “blue” waters of Galicia! 🌊🟢 Still chasing one more elusive species… but we’re out there, ready! 🦈🔍🤿

Tagging season never stops!! 💪

Density-dependent network structuring within and across wild animal systems Nature Ecology & Evolution - The number of individuals in a given space influences animal interactions and network dynamics. Here the authors identify general rules underlying density...

Happy that my shark data contributed to this collaborative paper brilliantly led by @gfalbery.bsky.social on animal social networks. Out in @natecoevo.nature.com

If density drives greater network connectedness, >80% of relationships are nonlinear (75% with saturating trends).

I hope you are going through your week like this small spotted catshark interacting with a sea lettuce 🦈 🥬

More to come in and outside the Ría de Vigo 👀

Científicos descubren cómo se comportan los tiburones y las rayas en la ría de Vigo El proyecto Belas desarrolla iniciativas para preservar los elasmobranquios, que son vitales para mantener el ecosistema costero. Ya han marcado 215 ejemplares de siete familias

Thrilled to see our project featured in #LaVozdeGalicia! 🦈✨

The article showcases the behaviour of sharks and rays in the Ría de Vigo, with a stunning underwater montage by #JoseIrisarriCastro 👏

We’re back in the blue! 🌊
Our third BRUV season has officially kicked off, and it’s already looking promising:

63 deployments ⛵
73 hours of underwater footage 🎥
4 elasmobranch species spotted 🦈

More to come in and outside the Ría de Vigo 👀

This octopus grew a ninth arm—which soon developed a mind of its own Study highlights just how flexible cephalopod’s bodies are after injury and during recovery

Nice feature of the incredible work done by Jorge Urcera on octopus arm regeneration featured in @science.org! 🐙🐙

A bifurcated limb showing signs of autonomous behaviour. Another example of octopus complexity.

Amazing!
Will it be on a "first come first served basis"? Or can we apply later without the risk of not having places left? 😀

I will forever be haunted by this footage.

Trawling has only been filmed underwater a few times in documentary history, and never with such clarity.

What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives.

A new species joins the crew. Yesterday we tagged our first Raja montagui in the wild! 🦈🥞

Tagging season is in full swing!! 💪

Congrats!!🥳🥳

We’re back at it! 🎣🦈
Tagging season is officially underway again in the Ría de Vigo 🌊🌞
Kicking things off with the same mission: understanding movement, behaviour & connections of our elasmobranch friends.

Stay tuned for more field updates, fins, and (hopefully) successful recaptures! 💪

Do you work with skates or rays? 👀

Go and check out the freshly published review paper, led by Danielle L. Orrell, about the best practice recommendations for capture, handling, anaesthesia, euthanasia and tag attachment!🎣✋🏼💉🪡

Amazing❗❗
I will check it out 🦈🦈

Wow👀
Very interesting and nice blog‼️
Looks like I have my plan cut out for tomorrow 😀
Thank you so much for sharing this

Thank you so much!
I will give it a try 💪

Will be there! 🦈

Tank you for the recomendation :)

Perfect!
I was just considering joining my first @oceantracking.bsky.social study hall :)

Let's see if someone else has another trick? @aquatictracking.bsky.social 👀👀

I will give it a try 😀
Thank you!

Thank you very much for the recommendation, Chris!

However, I don’t think this approach would work in my case because I’d have to repeat the process for each tagged fish.
😅

It would be a bit too much to handle case by case. I’m looking for something a bit more automated if possible.

I'm plotting fish detections between acoustic telemetry receivers in #R using geom_path()… But my tracks are overlapping like sardines in a can — and even worse, some swim straight through land! 😱🏝️ I’d love to add some curves between detection points to avoid both overlapping paths and any accidental land crossings.

Hola, fishy data lovers! 🐠💻

Quick question for all you R wizards out there:
How do you make some elegant, non-overlapping curves between two detected points in #R? Asking for a friend (aka me)… 👀🐟

I'm wrangling with #geom_path() and well it's winning.
Any tricks? Hacks? I'm all ears (and fins) 🦈🦈
