I am hiring a PhD student to join our group in Lund, Sweden working on an ERC-funded project to untangle color and polarization vision in some amazing crustaceans – minute water fleas and pugnacious mantis shrimp! Please forward this to promising students. Apply here: lu.varbi.com/en/what:job/...

Last week we had two fantastic speakers join us at the University of Exeter Penryn campus @uniexecec.bsky.social for our annual Darwin Week celebration! Thank you to both @matteosanton.bsky.social and Andrew Hendry for each of your inspiring seminars and workshops. We have loved hosting you!

I wasn’t aware of how cute and interesting cuttlefish could be until @matteosanton.bsky.social showed us his research at @uniexecec.bsky.social Those pattern changes during predation are really mesmerising!🦑

My collaborator at University of Copenhagen, Anders Garm, is looking for a 3 year postdoc to work on bioluminescence, neurobiology and ecology of ctenophores. More information here: candidate.hr-manager.net/ApplicationI...

Reposting for the Monday morning scrollers! Funded PhD opportunity with me @multipleye-lab.bsky.social @bristolbiosci.bsky.social - spiders, their eyes, and their babies under long- and short-term light pollution!

Exciting times ahead - I'm beyond delighted to be joining @bristolbiosci.bsky.social in 2026! 🎉🕷️🎉🐌🎉 I'm also looking for a PhD student to join @multipleye-lab.bsky.social in our new home! Come and study the effects of light pollution on the evolution and development of spider eyes with us 🌃🕷️👀 👇

🐠💥2 year postdoc in fish sensory ecology!! 💥🐟 If you’re into animal colour, collective behaviour, predator-prey interactions, enjoy behavioural experiments and fieldwork, please apply! Based in Oxford with fieldwork in northwest Thailand (and elsewhere). Please repost! www.jobs.ac.uk/job/DNM294/p...

Our study published in Ecology was recently mentioned in the latest issue of Science.

With its UFO-like display, the cuttlefish may look like it’s trying to get attention—but its intent is anything but. The undulating black stripes confuse prey, making the creatures all but invisible to crabs and other victims: scim.ag/3FVL43z

In our latest paper, we describe how the passing-stripe hunting display of the broadclub cuttlefish camouflages the hunting predator during the final moments of the attack. Read more here www.science.org/doi/10.1126/... @drmartinjhow.bsky.social @jtroscianko.bsky.social @bristolbiosci.bsky.social

Great @nytimes.com article on our latest cuttlefish study. Watch this space for more cuttlefish science soon! @ecologyofvision.bsky.social @bristolbiosci.bsky.social @drmartinjhow.bsky.social @vancedberg.bsky.social

What a Crab Sees Before It Gets Eaten by a Cuttlefish (Gift Article)

Cuttlefish use visual tricks to avoid being eaten. New research shows how they deploy similar camouflage to bamboozle their prey.

In new video footage, cuttlefish show off their dazzling camouflage techniques, such as creating stripes that move over their bodies or mimicking non-threatening objects

First paper out on this incredible study system! We describe the remarkably different hunting displays used by the broadclub cuttlefish in the wild. Paper: dx.doi.org/10.1002/ecy.... Stay tuned for more!! @drmartinjhow.bsky.social @vancedberg.bsky.social @ecologyofvision.bsky.social

Our latest paper on the jump kinematics and choreography in the Oz Splendid Peacock spider. We filmed & analysed locomotory jumps in male & female spiders. The males are incredibly light - measuring just 2mg - and oh they can jump! Videos in the thread. Open Access - read here: tinyurl.com/4bnpz9tz

With 12 photoreceptor classes, mantis shrimps have highly complex eyes. A study from Justin Marshall's lab shows behavioral evidence for color opponency, shedding light on visual processing in these eyes. journals.biologists.com/jeb/article/... 🧠 🧪 @jexpbiol.bsky.social Photo credit: Roy Caldwell
