Emydoidea blandingii
A semi-aquatic North American turtle with a bright yellow chin and throat. Its domed shell is speckled with yellow and its hinged plastron partly closes. It is known for showing almost no signs of aging.
Blanding's turtle is a semi-aquatic emydid centered on the Great Lakes, ranging from southern Canada (Ontario, south-western Quebec and parts of Nova Scotia) into the north-central and north-eastern United States (Minnesota, Wisconsin, Michigan, Illinois, Nebraska and elsewhere). Its genus is debated: the Reptile Database uses Emydoidea blandingii, while GBIF places it in Emys with the European pond turtle. Average straight carapace length is 18-23 cm, with a maximum of 25.5 cm. The key feature is the bright yellow chin and throat, and Indigenous tradition calls it the turtle with the sun under its chin. The domed carapace is slightly flattened along the midline and speckled with many yellow flecks on a dark background. The yellow plastron has symmetrical dark blotches and a hinge, but it does not close as tightly as a box turtle's. It takes 14 to 20 years to mature and stays active and fertile into its eighties and nineties, making it of interest to aging research. It is an omnivore that eats crustaceans, insects, snails, fish, frogs, carrion, berries and aquatic plants, and it is an agile swimmer. It is considered endangered across much of its range. It is rare in Japan, where captive-bred animals appear only occasionally.

Omnivore (crustaceans, insects, snails, fish, aquatic plants, berries)
An agile swimmer that approaches 25 cm, so it needs a large setup with ample water and a haul-out area.
An omnivore taking crayfish, aquatic insects, snails, fish, frogs, carrion, berries and aquatic plants; combine pellets with animal foods and plants.
Wild animals brumate in or under water, mud or vegetation; as a northern species, avoid prolonged heat.
Timid; when disturbed it withdraws into the shell or stays underwater for hours.
It takes 14-20 years to mature and can live beyond 80 or 90 years, so plan for care that may outlive the owner.
Both Emydoidea and Emys are used for the genus. It is endangered across much of its range, so choose captive-bred animals. Never release a captive animal into the wild.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
