Gonatodes spp. display marked sexual dimorphism.  The female (left) of Gonatodes albogularis is relatively drab compared to the male (right).   She’s still quite beautiful.

  A blind, fossorial snake, we found this Leptotyphlops on the sidewalk, curiously enough.  It’s a tiny, energetic snake and was very difficult to photograph.  The tail has a bit of yellow and an odd spin (Wikipedia won’t tell me what it is for…).
