Emydoidea blandingii (*)
The Blanding's turtle (Emys blandingii or Emydoidea blandingii) is a semi-aquatic turtle of the family Emydidae. It is considered to be an endangered species throughout much of its range.
Its genus classification is mixed with both Emys and Emydoidea in favor among published sources in 2009 and 2010.
The Blanding's turtle is a medium-sized turtle with an average shell length of approximately 18 to 23 cm (7.1 to 9.1 in) with a maximum of 25.5 cm (10.0 in). A distinguishing feature of this turtle is the bright yellow chin and throat. The carapace, or upper shell, is domed, but slightly flattened along the midline, and is oblong when viewed from above. The carapace is speckled with numerous yellow or light-colored flecks or streaks on a dark background. The plastron, or lower shell, is yellow with dark blotches symmetrically arranged. The head and legs are dark, and usually speckled or mottled with yellow. The Blanding's turtle is also called the "semi-box" turtle, for although the plastron is hinged, the plastral lobes do not shut as tight as the box turtle's.
Blanding's turtles take 14–20 years to reach sexual maturity. Mating probably occurs in April and early May with nesting beginning in early June and lasting throughout the month. The clutch size varies from region to region. In New York, the clutch size ranges from 5–12 eggs with an average of eight.
Behavior and life span
The Blanding's turtle overwinters under or near water, in mud or under vegetation or debris. During the nesting season, a female Blanding's turtle may be found more than a kilometer from where it hibernated. It is omnivorous, eating crustaceans and other invertebrates, fish, frogs, crayfish, carrion, berries and vegetable debris. It is capable of catching live fish. The Blanding's turtle may live to be 80 years old.
The Blanding's is a timid turtle and may plunge into water and remain on the bottom for hours when alarmed. If away from water, the turtle will close itself up within its shell. It is very gentle and rarely attempts to bite. It is very agile and a good swimmer.
Distribution and habitat
The primary threat to the Blanding's turtle is habitat fragmentation and destruction as well as nest predation. It is listed as an endangered species in the states of Indiana, Illinois, Maine, Nebraska, Massachusetts, South Dakota, Missouri, and Nova Scotia, though it has no federal status in the US. The Blanding's turtle is also fully protected in Michigan as a special concern species. In Canada, Blanding's turtles have been listed as either threatened or endangered throughout their range. The Great Lakes /St. Lawrence population in Ontario and Quebec is federally threatened  and the Nova Scotia population is endangered.
