Looks how to spot one

High-domed shell with a hinged plastron

A tall, rounded top shell with growth rings on each scute, and a hinged lower shell that lets the turtle pull in and close itself up almost completely, like a box. The shell is brown with a highly individual pattern of yellow or orange lines, spots and blotches. Males usually have red eyes, females yellowish-brown ones.13

Coloursbrown shell with yellow or orange lines, spots and blotchesdark brown plastronred eyes in males, yellow-brown in females3

Personality what they are like

Quiet and easygoing, a turtle that tends to shut itself in its shell when startled rather than flee. Wild individuals share overlapping home ranges without squabbling.12

Daily activity how busy a day looks

Active in daylight, especially in the early morning and after rain. Loves to dig into soil and leaf litter. Northern turtles go dormant (brumate) from about October to April, while southern ones may stay active all year.213

Grooming and care the hands-on bits

Provide a very shallow, wide water pan (under about 5 cm deep) for drinking and soaking, and a deep layer of moist dead leaves to burrow into. An outdoor pen with morning sun and plenty of shade is the preferred setup.4

Home where they are happiest

Ideally a large, secure outdoor pen with sun, shade and leaf litter; bury the fence a few centimetres and angle the top inward to stop escapes. An indoor tub works only as a temporary setup, with a 40-60 W heat lamp over one end and moist leaves or sphagnum peat as substrate.42

Food basics what goes in the bowl

A true omnivore. Young turtles eat more animal food, and adults lean more towards plants after about 5-6 years. Wild foods include earthworms, snails, slugs, insects, berries, mushrooms, roots and flowers. Keepers commonly offer earthworms alongside soft fruit such as strawberries or melon and leafy greens.2314

Company who they like around

A solitary but tolerant animal. In captivity keep only one male per enclosure, as males can clash; females can usually share. Hatchlings are best raised separately.41

The story where it all began

Box turtles are a uniquely North American group, and this species once ranged as far north as southern Ontario. The eastern subspecies became the official state reptile of both North Carolina and Tennessee, and the species is protected in international trade under CITES Appendix II.32

Fun facts for the dinner table

  1. 1

    One common box turtle is documented as having lived at least 138 years.3

  2. 2

    Its shell has a remarkable ability to regrow, and full regeneration of the top shell has been recorded.1

  3. 3

    They have a homing instinct that helps them find their way back to familiar places.2

  4. 4

    To cool down on hot days, a box turtle may spread saliva or urine on its legs so evaporation lowers its temperature.3

  5. 5

    You can often tell the sexes apart by eye colour: males tend to have red irises.3
