Behaviour

Like other box turtles it lives its whole life within a small home range and closes its hinged shell when threatened. It is most active after rain and in the morning, and burrows in for winter.

Why they matter

Box turtles spread the seeds of the fruit they eat and eat slugs and snails. They breed slowly, so road deaths and collecting reduce them for decades.

Reproduction and lifecycle

Nest — Dug in open soil
Eggs — Usually 3 to 8
Incubation — About 70 to 90 days
Hatchlings — Small and secretive
Maturity — At several years
Lifespan — Several decades

Living around people

  • Carry one across a road in the direction it was heading. Never move a box turtle to a new place; it wanders until it dies.
  • Never put a box turtle in a pond; it can drown.

Misconceptions

  • A box turtle far from water is lost. It is a land turtle, at home in woods and fields.
