    Hey All,

    Is there a purpose to tubercles (raised bumps) on geckos? I'm referring to the rough knob-tailed desert species?

    Is it to mimic their environment or something else?

    Cheers,
    Brett

    That is a very interesting first photo, Brett!
    I have no idea about your question, though, but would be interested to find out.

    Id expect it to serve multiple purposes. As far as camouflage goes it breaks up their silhouette. The tubercles also assist in anchoring them in crevices while being harrassed by predators.

    Yeah I reckon it would help defuse the light.
    I was thinking it would also have to increase overall surface area, which could aid in thermo regulation.
