Species of the Week: The Wood Frog

Photo by Simon Lunn

Our #SpeciesOfTheWeek is the Wood Frog (Lithobates sylvaticus). As winter nears and temperatures drop, these frogs are becoming inactive for the season – they have special adaptations that allow them to survive the cold winter by tolerating the freezing of their blood and tissues! Typically settling down in spots close to the surface in soil and leaf litter, their breathing and heart rate begin to slow until stopping altogether. During this time, their bodies produce a special antifreeze substance that prevents ice from forming within their cells, which would otherwise cause them to burst. They will then remain in this dormant state until the weather warms again in the spring when they will thaw and begin mating. Here at Murphys Point, we often find Wood Frogs in the campgrounds as they like to live in the leaves on the forest floor where they can camouflage and hide from predators. Have you ever seen a Wood Frog while camping here at the park?
