🚨 New paper alert! 👀In our new opinion piece in @Trends_Ecol_Evo, we propose #cephalopods as model systems to investigate the link between tactical #deception and #cognition in animals 🐙🦑🪄✨🧠

🤝 A HUGE thanks to @CamESS_CCLEAR for funding this work, to the @EcologyofVision group for inviting me to their lab at @BristolBioSci to conduct these experiments, and to my wonderful co-authors (and PhD supervisors) @JHerbertread and @DrMartinJohnHow 🥳🎉💪

🚨We are delighted to announce that our new paper is out NOW in @CurrentBiology 🦑🌅Here we show how #cuttlefish alter their #camouflage response under naturally occuring dynamic lighting ('water caustics')!

🚨So thrilled to announce that I've passed my PhD viva this week! A big thanks to @SensoryEcology and @EdgarCTurner for the great viva, as well as @JHerbertread and my lab @MarineBehavEcol for the most amazing cephalopod and crustacean-themed presents!🦑🦀

🌟CONGRATULATIONS🌟 to @IslaBaila on the 1st paper from her #PhD. Celebrating #ECR success is right up there as the best part of my job.
Thanks to coauthors @BenWilliamsSci @JohnStratford_ @sharkslikejazz @DrSteveSimpson

🚨We are delighted to announce that our new paper is out in #Ethology 🦀🦐🦑 Here we show that dynamic illumination has limited influence on the habitat selection and behavioural activity of #crustaceans and #cephalopods.

Thrilled to be featured in #Forbes - I'm over the moon that our research is reaching so many interested people 🎺🐠
Scientists have discovered an unusual way trumpetfish stalk their prey by using other fish to disguise their deadly movements.

🚨 We are delighted to announce that our new paper is out TODAY in @CurrentBiology 🚨 Here we provide the first direct evidence of how a predator - the trumpetfish - can use ANOTHER ANIMAL for concealment when hunting!

Find out more about the first findings of my #PhD on the effect of dynamic visual noise of #cephalopod behaviour 🦑
"Visual noise from caustic flicker does not affect the hunting success of cuttlefish"
@Chris_Drerup , @DrMartinJohnHow and @JHerbertread tested whether caustic flicker impairs the hunting success of cuttlefish.

Have you ever wanted to continuously film underwater species and their behaviours for up to 2 days at a low cost?
Well now you can with our new open-source design guide published in @MethodsEcolEvol!

🚨New paper alert!🦑... and again it's all about #bobtailsquids! In my #review in #MolluscanResearch, I summarise everything we know about the behavioural ecology of these charismatic #cephalopods. Have a look at this thread for a brief summary.

🚨 NEW PAPER 🚨 Traffic calming boosts breeding on coral reefs
Slowing down and giving reefs a wider berth boosts #fish breeding - encouraging growth and improving survival. Is it time to adopt acoustic sanctuaries? #OceanOptimism #CoralReefs rdcu.be/cNYqG How? A🧵

New paper!🚨When COVID prevented fieldwork, citizen science became the saviour! Using divers' observations across the Caribbean, we mapped the distribution of an intriguing trumpetfish foraging behaviour @JHerbertread @EGMitchell @CamZoology doi.org/10.1007/s00227-022-0…📸@Chris_Drerup

My first publication is now out in @ASNAmNat !! Natural visual noise reduces the ability of sticklebacks to respond to prey and in response they can adapt their behaviour to avoid these visually noisy areas. With @JHerbertread @C_C_Ioannou @ChrisRReid1 journals.uchicago.edu/doi/10…

🚨I know I talk a lot about the #burying #behaviour of #bobtailsquids, but do you know that the closely related #bottletailsquids also display a similar burying pattern. Check out my new #paper describing this cool feature for the tropical #bottletail #squid #Sepiadarium kochii🐙

So happy to share our new paper, hot off the press with @ICES_ASC!
We use #wrasse as a case study for assessing the #sustainability of inshore multispecies #fisheries, using data from @CornwallIFCA and @DevonSevernIFCA 🐟
