Spring sea slugs - so many around at the moment. The once rare rainbow #seaslugs are becoming quite common, more Polycera around than I’ve seen before, my second ever disco Doris. Here’s some recent clips
- a teaser before something bigger out next week…

60,000 oysters have been dropped into the Firth of Forth in restoration project Restoration Forth has reintroduced 60,000 European flat oysters to the Firth of Forth, doubling targets to restore lost oyster beds and boost marine…

🎉 Thing we love to see! 60,000 oysters restored to the Firth of Forth, Scotland 🦪

Previously wiped out by overfishing & pollution, it's heartening to see this vital habitat coming back, filtering water & bringing marine life with it 🌊

A tiny hermit crab is bullied and knocked upside-down. No worries, though, as she gets back up and then pulls her house back over her head for protection! 🦀🦑

The largest rockpool we run field trials in. Three floats can be seen in the water, in the sun with blue sky above.

The rocky shore half an hour later, with very ominous grey clouds and rain in the distance over St Andrews.

Fieldwork photos taken 30 minutes apart and just before we got rained on quite spectacularly!
You really do just have to wait half an hour in Scotland if you don't like the weather ☀️🌊☔

Amazon waterway noise threatens unique social life of giant river turtles Hatchlings talk inside their shells to time their birth, but the roar of massive barges may soon drown out their sound.

A new Amazon shipping waterway for grain exports may silence the sophisticated communication of the giant river turtle.

Scientists warn that industrial noise threatens this likely endangered species’ unique social life and migration patterns.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South Af....

Since our first review didn't identify any soniferous fishes from the Antarctic, we are so happy that folks are exploring this great unknown in fish #bioacoustics!

Last weekend's reading and exploring 🌿☀️📚
I thoroughly recommend this book by @robgmacfarlane.bsky.social for those who have not yet read! Also thoroughly recommend a walk around Burnhope Reservoir in County Durham for people around those parts!

An algorithm underlying directional hearing in fish Veith et al. show how a fish—Danionella cerebrum—can reliably startle away from sound. It uses the relative phase between particle motion and pressure to infer the direction of sound. This sensorimoto...

How do fish localize sound without interaural cues? @johve.bsky.social et al. found a behavioral algorithm for directional hearing that predicts behavior from a pressure/motion phase comparison and accounts for how this relationship varies with distance. www.cell.com/current-biol...

Pleased to announce the BioDCASE Challenge 2026 - the Bioacoustics Data Challenge! Now with 6 different tasks to choose from, each an open-data computational challenge of its own: https://biodcase.github.io/challenge2026/ #machinelistening #BioDCASE #bioacoustics #DCASE #sound

We saw so many ragworms during fieldwork today, bright green for the breeding season! @animalsdoingstuff.bsky.social

How to draw a hermit crab

The thumbnail of a youtube video. A hand carries a minuscule microphone in front of a bird of prey, who is staring at it intently. The title of the video reads "I interviewed animals with a tiny mic again".

No one:
Bioacousticians:

Two crabs (Cryptosoma bairdii) in mating posture (the male is larger and is sort of enveloping/hugging the smaller female). They are calappids, so they have big broad claws and cute eyestalks

Valentine's Day themed crab thread! ❤️🦀🦑🧪

The shamefaced heart crab, Cryptosoma bairdii, has nothing to be ashamed of because we love them (and in this photo, they love each other if you know what I mean)

A brief break from the beautiful Scottish weather we've been having lately finally allowed us to get out for a little spot of fieldwork yesterday! @animalsdoingstuff.bsky.social 🦀☔🪸

So excited to see this recommendation coming from the Animal Sentience Committee, really hoping it leads to some real change in decapod protection

Government criticised for ‘glacial pace’ writing UN high seas treaty into law The Government is moving at a “glacial pace” to ratify a landmark UN pact to protect delicate ecosystems in international waters, a coalition of green groups has said.

🌊 "As an ocean nation, we can & should be leading the way" @hugotagholm.bsky.social

The #HighSeasTreaty has entered into force thanks to the 81 countries who ratified it. Incredible news. But where's the UK? The govt MUST move to ratify, before we're left behind

🐦Community composition coupled with habitat fragmentation drives acoustic divergence in bird assemblages

It turns out all species (Atlantic & Pacific) do, yet little is known about how this evolved. A novel structure found only in the Atlantic species offered the answer, but it isn't quite what you think...🌍 🧪

ShoalBase | Join, Explore, Contribute Now ShoalBase offers a global database on fish social behaviour, supporting research, conservation, and ecology through community contributions and visual data mapping.

🧵1/9 There are 35,000+ fish species, but we have formal social-behaviour classifications for a tiny fraction. Most knowledge lives in the experience of researchers, fishers, divers, aquarists, naturalists, and Indigenous communities, but almost none of it is centralised. So we built ShoalBase.org.
