#' Fiddler crab body size in salt marshes from Florida to Massachusetts, USA at PIE and VCR LTER and NOAA NERR sites during summer 2016.
#'
#' We collected ~30 male, adult Minuca pugnax from thirteen marshes from  Florida to Massachusetts and measured their carapace width with calipers. Water and air temperature data were collected from monitoring programs (i.e., LTER, NERR sites), nearby weather stations, and ocean buoys for 2016.
