QI of the Day: “Why do fish have stripes and spots?”
“To confuse and scare predators”
Actually, recent research by Kelly et al provides a range of counter evidence that the leading theories, ie. “Predator defence by mimicking predators’ enemies’ eyes, deflecting attacks or intimidating predators…Striped body patterns have been suggested to serve for both social communication and predator defence.”). These hypothesis are contradicted by a range of data and observations. For example, “Contrary to our expectations, spots and eyespots appeared relatively recently in butterflyfish evolution and are highly evolutionarily labile, suggesting that they are unlikely to have played an important part in the evolutionary history of the group.”
And why does the Cocoon resort have a trompe l’oeil shadow on the wall of a wrought iron grille as if the sun was shining through some window on the Riviera? Just for a bit of aesthetic whimsy (maybe that is an explanation for reef fish too). Even more mysterious is how the shadow is created as there is absolutely nothing on the villa windows except what appears to be clear glass. It’s a bit more design wizardry from the resort…floating furniture, shadows of invisible things – it’s like staying a Hogwarts. Magic all over the resort from the reef to the rooms.
