Remember the Mexican wave? A few months ago, our Fish Lab published a very exciting paper about sulphur mollies and how they collectively perform a very interesting wave to dissuade and distract predators. This behavior is so unique that dozens of news outlets around the world picked up the news and published articles about it (see them in our Press Review). Now, the Fish Lab went back to Mexico to see if collectives of fish can distinguish different predator bird species and if so, to understand how they do it.
While on their trip, our researchers sent us pictures to give a glimpse of their typical day on the field, and it looks really exciting. Scroll all the way down for captions and credits.
