The incredible diversity of life in tidal creeks and rivers has attracted me since childhood.  And while invertebrates and fishes predominate, areas where fresh and salt water meet hold wonderful surprises for reptile enthusiasts as well.  Today I’d like to discuss a turtle that I often find in brackish water habitats, and which seems to be evolving unique adaptations to survive there – the Snapping Turtle, Chelydra serpentina.
