The eastern mud turtle (Kinosternon subrubrum) or common mud turtle is a common species of turtle in the family Kinosternidae. The species is endemic to the United States. There are two recognized subspecies. The eastern mud turtle is a small and often hard to identify species. It measures 3–4 in (7.6–10.2 cm) in carapace length. The carapace is keelless, lacks any pattern, and varies in color from yellowish to black. The plastron is large and double hinged, and can be yellowish to brown, and may sometimes have a dark pattern. The chin and throat are a yellowish grey, streaked and mottled with brown, while the limbs and tail are grayish. The eye, or iris, of the eastern mud turtle is yellow with dark clouding, and its feet are webbed.
The specific name, subrubrum, meaning "under red", refers to the red-orange plastron of hatchlings. The eastern mud turtle is omnivorous and feeds on insects, crustaceans, mollusks, amphibians, carrion, and aquatic vegetation. Smaller eastern mud turtles prey on small aquatic insects, algae, and carrion, whereas larger ones can feed on any type of food that they can fit in their mouth.

Rare
Under 5% of wildlife watchers report an Eastern Mud Turtle sighting in Washington on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 25 reptiles we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Eastern Mud Turtle in Washington on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Eastern Mud Turtle sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.

GBIF citizen-science records
It is estimated from how often the Eastern Mud Turtle is recorded against all the reptiles logged in Washington (24 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
