New paper on fish camouflage๐ŸŸ We placed scorpionfish on backgrounds of different pattern granularity to see whether they adjust their skin pattern. Find out what changes we observed! With @MatteoSanton @MicaToolbox https://t.co/1r813Ta3r7

Having a great time at #Behaviour2023. Be sure to check out my talk Thursday afternoon at 17:00 in seminar room 1. I'll be showing the importance of light and geometry for the mechanisms of animal camouflage.

Our new model of colour appearance shows how many visual illusions can be explained by the limits of early low-level visual neurones. e.g. why sometimes a dark surround makes a target lighter, and other times darker. https://t.co/gFZ2bpS5aB

So happy that my first PhD paper is finally OUT! ๐ŸŸ We show that scorpionfish change colour in response to their background within seconds and what this looks like from their prey's visual perspective. https://t.co/kWFxLK4qjn #camouflage #colsci @MicaToolbox @MatteoSanton
