    Keeled scales.

    I've been wondering why garters have evolved keeled scales.What advantages do they get from this adaption?

    Found this info. Seems to make sense.

    Awesome link...I had no idea about the stridulating...but it is very cool. I think the camoflauge thing makes perfect sense.

    Never heard of "stridulation" before. That is pretty interesting.

    Cool Re: Keeled scales.

    The "stridulation" is not the reason why garter snakes have keeled scales. The "being less shine" can be a reason, but i suspect the most important reason why they have keeled scales is that it helps during the swimming. They can get more resistance that way, I guess. When you are completely smooth the swimming is less effective.

    Re: Keeled scales.

    Well...the link that Steve posted actually said that the keeled scales were more for camoflauging purposes...the "less shine" effect. I can see them being effective for swimming purposes as well. I think the mention of stridulation was just an added..."this is cool too"...factor.

    Re: Keeled scales.

    I hadn't even thought about stridulation in snakes before, but I've had some pretty large spider stridulate at me before. I would have to agree with the camouflage theory though. I'm sure keeled scaled would help with swimming though

    What about aquatic snakes that don't have keeled scales and fully terrestrial snakes that do? And if the keels help with swimming, it should work on land as well, against the substrate and vegetation.
