, lacking the broad belly-scales found in most other snakes and possessing dorsally located eyes. Their most notable feature is their skin and scales. The skin is loose and baggy, giving the impression of being several sizes too large for the snake, and the scales, rather than overlapping, are tiny pyramidal projections that led to their common names.
