About the Western Pond Turtle
The western pond turtle (Actinemys marmorata), also known commonly as the Pacific pond turtle is a species of small to medium-sized turtle in the family Emydidae. The species is endemic to the western coast of the United States and Mexico, ranging from western Washington state to northern Baja California. It was formerly found in Canada (in British Columbia), but in May 2002, the Canadian Species at Risk Act listed the Pacific pond turtle as being extirpated.
Its genus classification is mixed. Emys and Actinemys were used among published sources in 2010. It was known by several names in the Indigenous languages of its range, including kʰá:wanaka: (Northeastern Pomo), kʰa:wana (Southern Pomo), and ʔaləšək (Lushootseed).
The dorsal color of A. marmorata is usually dark brown or dull olive, with or without darker reticulations or streaking. The plastron is yellowish, sometimes with dark blotches in the centers of the scutes. The straight carapace length is 11–21 cm (4.5–8.5 in). The carapace is low and broad, usually widest behind the middle, and in adults is smooth, lacking a keel or serrations. Adult western pond turtles are sexually dimorphic... Wikipedia →
