Pliocercus euryzonus burghardti — Black Halloween Snake
Joseph Ehrenberger spotted this pretty snake as it prowled slowly along the creek's edge. Neither of us were sure that it was not a coral snake, so we just watched it crawl around as we waited for the rest of our group to join us. (Matt Cage eventually arrived and identified the snake as Pliocercus.) Note that in the second photo it has crawled right over a very young basilisk lizard without either animal apparently realizing this.
