The Eastern Mud Turtle (Kinosternon subrubrum) also referred to as the Common Mud Turtle sometimes, is a fascinating species native to the southeastern United States, known for its adaptability and distinct physical features. These small, semi-aquatic turtles typically measure between 3 to 5 inches in length and weigh around 1 to 1.5 pounds. They have smooth, dome-shaped shells that range in color from brown to black, with a yellowish or cream-colored plastron. Some individuals exhibit subtle pattern variations on their shells, depending on their genetics and habitat. A key feature distinguishing the Eastern Mud Turtle from other turtles is its hinged plastron, which allows it to close its shell tightly for protection.
Eastern Mud Turtles are found in wetland environments such as marshes, ponds, slow-moving rivers, and muddy swamps. They are particularly suited to climates with warm summers and mild winters. During colder months, they exhibit brumation, a hibernation-like state, by burying themselves in mud or debris to survive low temperatures. Males are typically smaller than females and have a concave plastron and thicker tails, while females possess a flatter underside and broader shell. Compared to other mud turtles, Eastern Mud Turtles have smoother, more uniformly colored shells with fewer ridges.
This species is native to the United States, with a range extending from New Jersey to Texas and southward to Florida. In the wild, they prefer shallow water with soft substrates and plenty of vegetation, where they can find food and lay eggs. Breeding occurs in spring and fall, with males actively pursuing females. Females lay 2 to 6 eggs in shallow nests near water, often in loose soil or sand. Hatchlings emerge after 80 to 100 days of incubation. In captivity, successful breeding requires a carefully managed environment, including separate nesting areas and controlled temperatures to replicate natural conditions.

Eastern Mud Turtle Care Guide
Caring for an Eastern Mud Turtle requires attention to their health, environment, and diet. These turtles are hardy but can face health problems such as shell rot, respiratory infections, and vitamin deficiencies. Shell rot, often caused by poor water quality or fungal infections, manifests as discoloration or soft spots on the shell. It can be prevented through regular water changes and tank maintenance. Respiratory infections, linked to improper temperature or humidity, show symptoms like wheezing or nasal discharge. Regular UVB lighting ensures they receive adequate vitamin D3, essential for shell and bone health.
Grooming needs for these turtles are minimal, involving occasional cleaning of the shell with a soft brush to remove algae or debris. They generally do not enjoy handling and can become stressed if overhandled. While not highly interactive, they can recognize feeding times and respond to their owner’s presence.
Annual ownership costs for Eastern Mud Turtles vary but typically fall between $250 to $400, excluding the initial setup. Initial costs include a tank, lighting, filtration system, and heating equipment, ranging from $150 to $300. Recurring expenses include food, electricity for heating and lighting, and occasional veterinary checkups. Reputable turtle care brands like Zoo Med, Fluker’s, and Exo Terra offer products for their care, and these can be purchased online through retailers such as Amazon or Chewy.
Yes, Eastern Mud Turtles are aquatic. They live in freshwater environments like marshes and ponds. They also spend time on land during hot or dry seasons by digging into the ground.
Eastern Mud Turtles are not fully nocturnal. They are active during the day and early evening. At night, they often stay hidden in water or mud for safety and rest.
Eastern Mud Turtles are omnivores and require a diet that combines animal protein, plant matter, and commercial turtle pellets. Juveniles should be fed daily, while adults can be fed every other day. A balanced diet includes about 60% protein sources such as worms, shrimp, or small fish, and 30% plant matter like romaine lettuce or aquatic plants like duckweed. High-quality commercial pellets, such as those by Mazuri or Rep-Cal, make up the remaining 10% of their diet.
Avoid feeding them processed human food, high-fat meats, or nutrient-poor options like iceberg lettuce or spinach, which may contain harmful compounds. Fresh, live food such as mealworms or snails can provide enrichment while meeting their nutritional needs. Products from trusted brands are available on platforms like Amazon or specialty reptile stores.

Eastern Mud Turtle Indoor Habitat Requirements
Setting up a proper habitat for an Eastern Mud Turtle is critical to its well-being. A single turtle requires at least a 40-gallon tank, while a pair or group needs a larger enclosure of 75 gallons or more. Their enclosure should replicate their natural habitat, offering both water and land areas. A sandy or smooth gravel substrate, along with live plants like Anubias or floating vegetation, provides a stimulating environment. Adding driftwood and rocks creates hiding spots and mimics their natural surroundings.
The water temperature should be maintained between 72 to 78°F, with a basking area heated to 85 to 90°F. UVB lighting is essential to support their health, as it aids in calcium absorption and prevents shell deformities. Reliable UVB lamps like Zoo Med’s ReptiSun are highly recommended. Filtration is equally important to maintain water quality, and canister filters such as Fluval or Eheim are excellent options. Submersible heaters with built-in thermostats help stabilize water temperatures, while a digital thermometer ensures accurate monitoring.
When housing multiple turtles, ensure adequate space and hiding spots to reduce territorial aggression. Tanks should include ramps or basking platforms to allow easy access to land areas. For breeding setups, provide a sandy nesting area to encourage egg laying. Reputable manufacturers like Tetra and Aqueon offer high-quality tanks and equipment suitable for Eastern Mud Turtles.
Yes, Eastern Mud Turtles can carry Salmonella bacteria. It doesn’t affect the turtle but can be passed to humans through touch or by cleaning their tank or water.
It is generally legal to own an Eastern Mud Turtle in most U.S. states. However, check for restrictions in states like Georgia, New Jersey, or Hawaii, which have tighter wildlife laws.

Things an Eastern Mud Turtle Owner Should Consider Before Adopting One
Before adopting an Eastern Mud Turtle, it’s important to understand their behavior and habitat needs. These turtles are not particularly interactive but can be hand-fed and will engage with enrichment items like floating toys or live prey. They are unsuitable for free roaming outside their enclosure, as they require controlled temperatures and humidity.
Eastern Mud Turtles interact well with plants, rocks, and enrichment items in their tanks. Compatible tank mates include other non-aggressive turtles, small fish, or aquatic animals, but interactions should always be monitored. Enrichment can include food puzzles, basking platforms, or floating decorations, which help keep the turtle mentally stimulated. Products from Fluker’s or Exo Terra are widely available online and provide excellent options for enrichment.
