The Marsh or Helmeted Terrapin inhabits temporary pans and other slow moving and still waters. They appear in the rainy season and dig themselves into the mud to survive the dry season. They are also called side-necked terrapin since they do not retract their heads but flip them sideways into their shell when in danger. That way, one eye remains functional. This is a juvenile, about a month old and 5 cm long. Adults reach a size of up to 32 cm.
