Diet & Feeding

An omnivore eating worms, crayfish, frogs, snails, fish, fairy shrimp, leeches, aquatic insects, plants and carrion; combine pellets with animal foods.

Temperature & Humidity

In the wild it estivates underground for most of the year and is active in the rainy season, so its activity varies strongly by season.

Temperament

Females have been seen staying with their nests from a few hours up to 38 days after laying.

Health & Cautions

It can live more than 40 years, so plan long term.

Notes

Former subspecies such as the Arizona mud turtle are now widely treated as separate species; check the scientific name and origin. Never release a captive animal into the wild.

About Yellow Mud Turtle

A small turtle named for the yellow coloring on its throat and neck, with a flattened shell and hinged plastron. It can live over 40 years and suits intermediate keepers who enjoy quiet observation.

7 things to know before welcoming a Yellow Mud Turtle

1. 1Provide Deep, Diggable Substrate

   Yellow Mud Turtles spend a lot of time buried in substrate. Give them a deep enough layer to burrow into and hide completely, and keep it from drying out too much.

2. 2Balance Water and Land Areas

   This species isn't fully aquatic — it moves between water and land. Set up both a shallow water area and a dry land area in the enclosure so it can move freely between them.

3. 3Shy and Reserved by Nature

   This turtle tends to be quiet and reserved, preferring to stay hidden rather than be out in the open. It's better suited to keepers who enjoy watching from a distance rather than frequent handling.

4. 4A Unique Summer Dormancy

   In the wild, this species spends most of the year dormant underground in a behavior called aestivation. In captivity, its activity level can vary a lot with the seasons and environment, so don't be alarmed by quiet periods — just keep observing.

5. 5An Omnivorous, Varied Diet

   Yellow Mud Turtles are omnivores that eat both animal and plant matter. Basing the diet on a quality commercial turtle food supplemented with varied nutritious items helps support long-term health.

6. 6A Multi-Decade Commitment

   This turtle can live for more than 40 years, so caring for it is a long-term commitment that extends well beyond adulthood. Before bringing one home, think carefully about whether you can provide care for the long haul.

7. 7UV Light and Temperature Control

   UVB lighting and proper temperature management are essential for healthy shell and bone development. Set up a basking spot and a temperature gradient so the turtle can regulate its own body temperature.

Frequently asked questions about Yellow Mud Turtle

Q.How big do they grow?

A.Males reach up to about 16.8 cm in carapace length, while females max out around 12.8 cm — males grow larger than females in this species.

Q.How long do Yellow Mud Turtles live?

A.They're a long-lived species known to live for more than 40 years. It's important to consider whether you can commit to their care over such a long timeframe before bringing one home.

Q.Does it need an aquatic setup or a land setup?

A.It needs both — this species moves between water and land, so the enclosure should include a shallow water area as well as a dry land area. A layout that gives access to both is ideal.

Q.My turtle suddenly buried itself and stopped eating — is that normal?

A.Yellow Mud Turtles have a natural behavior called aestivation, where they burrow underground and become much less active. It's common for them to stay buried and go off food for a while during seasonal changes, so as long as there's no obvious sign of illness, it's fine to just keep an eye on them.
