The common basilisk likes to hang out along rivers and creeks, but they also climb well. Very well. One morning my son Ian and I were sitting on the couch in the open living area of El Fenix (my lovely treehouse) when Ian pointed at the tree that grows through this room. Mom, look! was followed a second later by a strange cry even for a teenager, as the very large male basilisk that had caught his attention leapt from the tree onto Ian's shoulder! More commonly this particular lounge lizard suns himself at the edge of the deck, where he can retire onto the tree if the humans are being annoying.
