Langjährige Haltung und Reproduktion der Spinnenschildkröte, Pyxis arachnoides arachnoides, bei kombinierter Freiland- und Innenhaltung mit Ästivationsphase.
Long-term care and reproduction of the spider tortoise, Pyxis arachnoides arachnoides, combining outdoor and indoor keeping, including aestivation.
, Sulzfeld & Hans-Jürgen Bidmon
Here the maintenance and breeding of the spider tortoise, Pyxis arachnoides arachnoides
is described. The tortoises are kept outdoors during the
summer with occasional interruption during longer periods of wet and cold weather when they returned to their indoor enclosures. After
that outdoor period the specimens are kept indoors to check their health status and in order to prepare them for a prolonged period of
aestivation in a room which is kept at about 18–16 °C and a relative humidity of 50 % or less. During that period the tortoises are lightly
hidden under dry hay. Only a small bowl of fresh water is present in case a tortoise decides to drink which happens rarely. For Pyxis arachnoides
aestivation belongs to an essential part of their natural life cycle which has to be provided for the welfare of the animals. Otherwise the tortoises
do not stay healthy and usually will not survive. This is probably one of the reasons why up to now there are no reports about (carapace)
pyramiding in Pyxis arachnoides
, because aestivating specimens show natural growth patterns during their annual life cycle despite the fact
that they feed on nutritious greens and non-aestivating specimens tend to die before pyramiding takes place. We refer to mating activity,
nesting and incubation conditions including the detailed temperature/humidity and incubation schedule used for both species, P. a. arachnoides
and A. radiata
. Furthermore, we describe their nutritional needs for the adults and for the raising of hatchlings and address issues that are
still open for discussion and further experimentation.
