Sandy feet! Whose feet?

"When a family spends a day at the beach, the children investigate various footprints to see what type of creatures live along the shoreline. Rhyming text turns a sandy beach into an outdoor classroom. The tracks and habits of local wildlife, including hopping sandpipers, scuttling crabs, and burrowing turtles, are identified and explained for young ecology detectives. STEM-based back matter includes information on how clues like footprints can identify the type of wildlife inhabiting any given habitat"--OCLC.
