hi guys, the other day i was at my local herpetological society(that is one confusing word ha ha) and was asked why garters scales are so keeled. I realy haven't the slightest clue how to answer that question. Another member in the group suggested that it might be becuase that snakes slither through loose debris and that the keels help keep the debris out from between the scales. I would realy like to know the correct answer to that question
