They say that wearing stripes can make you look thinner. Well, lizards don't care about looking sveled.

But their stripes might help them avoid getting caught by a hungry predator.

And not by camouflage. No, it may be that the stripes make them look like they're moving slower than they

really are, messing up the predator's timing. That's according to a report in the journal

Royal Society Open Science. Gopal Murali, at the Indian Institute of Science Education Research,

got interested in the question of why so many lizard sport stripes while perusing hundreds

of images of the

conspicuously decorated critters. Surprisingly, when we looked into the literature, we did not find

any direct experimental evidence for the role of striped coloration in lizards. Seems such eye-catching

coloration would make the bearers easier for predators to spot in the wild. So Morali wondered whether bright stripes might create a sort of optical illusion,

one that would disorient predators and maybe get them to grab a lizard's tail

rather than a more vital body part.

Since it is well known that the tail of lizard can be easily lost

and most of the predators are known to attack the head or body of the lizards,

we thought that the presence of contrasting stripes on the body of lizards in motion

might actually trick predators to attack the tail,
