Why is hiking in a zebra onesie a smart move if you want to avoid being devoured by flies? And why are skunks more stripy in predator-rich forests? Find out this, and more, from @bristolbiosci.bsky.social experts @drmartinjhow.bsky.social & Tim Caro on BBC CrowdScience: www.bbc.co.uk/programmes/w...

So keen to read THE RADIANT SEA by @stevehaddock.bsky.social & Sönke Johnsen! In the introduction, @helenscales.bsky.social says it's like having the authors "looking over your shoulder and telling stories," an experience I've been lucky enough to get with Steve. Also, COVER CEPHALOPOD 🐙🦑🌊

A huge thanks to my amazing co-authors @drmartinjhow.bsky.social and James Herbert-Read, as well as all members of the @marinebehavecol.bsky.social at @camzoology.bsky.social and @ecologyofvision.bsky.social for their help, and @thembauk.bsky.social for their brilliant logistical support! 🤝

Motion After‐Effects Induced by Dynamic Illumination in Crab Vision While in humans, background motion can disrupt the detection of visual cues even after the moving background component has ceased, it remains unknown whether natural forms of background motion might ...

🚨Our new paper is out NOW in @ecol-evol.bsky.social 👀 Here we show that prior exposure to dynamic illumination can have a persisting effect on the visual perception of 🦀, reducing their ability to detect predators even after the dynamic illumination has ended.

🤝 A HUGE thanks to @ecologyofvision.bsky.social group for inviting me to their lab at @bristolbiosci.bsky.social to conduct these experiments, and to my wonderful co-authors (and former PhD supervisors) James Herbert-Read (@marinebehavecol.bsky.social) and @drmartinjhow.bsky.social 🥳🎉💪

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.

Absolutely buzzing that my paper with Daniel, describing our discovery of electroreception in caterpillars, has been awarded the @pnas.org Cozzarelli Prize for the best paper in its field published last year! I should make little medals for the caterpillars and wasps 🥇🐛🐝

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.

Great @nytimes.com article on our latest cuttlefish study. Watch this space for more cuttlefish science soon!

Check out these amazing cuttlefish. Stealth hunting taken to the extreme!!!

First paper out on this incredible study system! We describe the remarkably different hunting displays used by the broadclub cuttlefish in the wild.
