what is it?

The western pond turtle ( Actinemys marmorata or Emys marmorata ), or Pacific pond turtle is a small to medium-sized turtle growing to approximately 20 cm (8 in) in carapace length. It is limited to the west coast of the United States of America and Mexico, ranging from western Washington state to northern Baja California. In May 2002, the Canadian Species at Risk Act listed the Pacific pond turtle as being extirpated in Canada.
