The common musk turtle, also known as the "stinkpot" due to its ability to emit a foul odor, is a popular pet turtle species. Belonging to the family Kinosternidae, these turtles are native to eastern North America and are known for their relatively small size and inquisitive nature. Understanding their dietary needs is crucial for ensuring their health and longevity in captivity.
Understanding the Common Musk Turtle
The common musk turtle (Kinosternon odoratus) is characterized by its blackish-brown, highly domed carapace with a vertebral keel, which tends to flatten out in adults. The plastron is reduced in size. These turtles are found in various aquatic habitats, including slow-flowing streams, rivers, lakes, and ponds, across a wide geographic range from Florida to Ontario, and west to Texas and Wisconsin. They typically reach a maximum carapace length of 4 to 4.5 inches, with males being slightly larger than females. A healthy common musk turtle can live for 30 to 50 years in the wild.
Dietary Needs of Common Musk Turtles
Common musk turtles are primarily carnivorous, with a diet consisting mainly of high-protein foods. In the wild, their diet includes small snails, mollusks, crayfish, and aquatic insects such as dragonfly and damselfly nymphs. They also actively hunt small tadpoles and terrestrial insects that fall into the water. Occasionally, they consume plant matter like Elodea species or duckweed.
In captivity, it is essential to replicate this varied diet to ensure the turtle receives all the necessary nutrients.
Recommended Food Items
Aquatic Turtle Pellets: Commercial aquatic turtle pellets are a convenient and readily available food source. These pellets are formulated to provide a balanced diet and are often accepted by common musk turtles.

Invertebrates: A variety of invertebrates can be offered, including:
- Earthworms
- Grasshoppers
- Crickets
- Ghost shrimp
- Small crayfish
Snails: While snails can be a part of their diet, it is crucial to avoid feeding wild-caught snails due to the risk of parasite transmission. Wild snails can be intermediate vectors for parasites that affect various animals, including lung flukes that can harm common musk turtles.
Algae Wafers & Tortoise Pellets: Spirulina algae wafers and commercial tortoise pellets can be offered as supplemental food items, providing additional nutrients and variety.
Feeding Guidelines
- Variety is Key: Offer a varied diet to ensure the turtle receives a wide range of nutrients.
- High-Protein Focus: Prioritize high-protein foods to meet their carnivorous needs.
- Supplementation: Consider supplementing their diet with calcium and vitamin D3, especially for indoor turtles that may not receive adequate UVB exposure.
- Avoid Overfeeding: Monitor the turtle's weight and adjust the amount of food accordingly to prevent obesity.
Setting Up the Ideal Habitat
Proper housing is essential for the health and well-being of common musk turtles.
Tank Size
A 20-gallon aquarium with a submersible canister water filter is suitable for one adult common musk turtle. A 40-gallon tank can house a pair, with a larger filter to handle the increased waste. Housing two male common musk turtles in the same tank is not recommended due to potential aggression.

Water Quality
Use non-chlorinated water in the enclosure. The water depth should allow the turtle to touch the bottom with its hind legs while still being able to stretch its neck to breathe at the surface without constant paddling. A strong filter system suitable for shallow water is necessary to maintain water quality. Regular tank cleaning is crucial, using dechlorinated water. Water care products can help reduce the time spent on upkeep.
Temperature and Lighting
Maintain a water temperature of around 80°F. While common musk turtles do not always bask, providing a dry basking area is still beneficial. Position a basking light above the spot where the turtle would bask, maintaining a temperature of about 90 degrees Fahrenheit in that area.
High-quality UVB bulbs are essential for turtles to metabolize calcium and avoid vitamin deficiencies. Keep lighting on a 12-hours-on/12-hours-off cycle to mimic natural conditions.
Substrate and Decorations
Substrate is not required, and a bare-bottomed tank is easier to clean. Decorations such as PVC pipes, driftwood, and rock piles can provide hiding spots and enrichment for the turtle. These decorations can also serve as basking sites if they break the surface of the water.
Handling and Interaction
Common musk turtles can be feisty and may bite if they feel threatened. Handle them gently and only when necessary. Keep your fingers toward the rear of the carapace to minimize the likelihood of a nip, but be aware that they have long, flexible necks.

Health Considerations
Like all basking turtles, common musk turtles are susceptible to vitamin A and D3 deficiencies. Ensure they receive a varied diet and adequate UVB exposure. Poor water quality can lead to eye and skin problems, such as pinkish skin, a pinkish plastron, and puffy skin or eyes. Maintain clean, oxygenated water to prevent these issues.
